ISO/IEC 17020 client experience
What it is
What is ISO/IEC 17020 and what is it used for?
ISO/IEC 17020 is the international standard for bodies performing inspection. It defines inspection as the "examination of an item and determination of its conformity with detailed requirements or, on the basis of professional judgement, with general requirements", and professional judgement is what separates inspection from testing: the inspector decides whether the item conforms, drawing on experience as much as on instruments. The standard sets out what a body needs for such judgements to be trusted: impartiality and a declared level of independence, competent and authorised inspectors, controlled equipment, documented methods, records, reports with the required content, a route for appeals and complaints, and a management system that keeps it all running.
It is not a certification standard. An inspection body is accredited: an accreditation body working to ISO/IEC 17011 reviews the documentation, sends assessors to the premises and into the field to witness inspections, examines the records behind the reports and, if satisfied, grants accreditation for a defined scope: the fields and types of inspection, items, methods or schemes and locations on a public schedule that regulators and purchasers use to decide whose reports they accept.
Current edition. ISO/IEC 17020:2026, the third edition, was published on 27 March 2026 and replaces ISO/IEC 17020:2012, now withdrawn. It categorises inspection bodies as Type A or Type non-A instead of Type A, B and C, strengthens impartiality and confidentiality, adds control of data and information and actions to address risks and opportunities, and aligns the management system clause with the ISO/IEC 17000 series common elements. ILAC resolved a transition of three years from publication, carried into Global ACI (Global Accreditation Cooperation Incorporated, which brought ILAC and IAF together on 1 January 2026; its MRA replaced the ILAC MRA and the IAF MLA), so accreditation to the 2012 edition is expected to cease to be recognised on 27 March 2029, subject to your accreditation body's own timetable. ISO/IEC 17020 requirements explained, clause by clause
Who it is for
Who needs ISO/IEC 17020 accreditation?
The standard applies to any body that performs inspection, whether inspection is its business or a function inside a larger organisation: independent inspection agencies, third-party inspectors in oil and gas and construction, lifting and pressure equipment inspectors, vehicle, vessel and cargo inspectors, and the inspection departments of manufacturers, operators and utilities. The scope you apply for should describe the inspections your clients and regulators rely on, not every service you could offer. Inspection bodies come to Sterling from four starting points:
- A regulator or a scheme owner requires accredited inspection. Many regulators require, or prefer, statutory inspections of lifting equipment, pressure systems, installations or vehicles by an accredited body, and sector schemes often make accreditation the entry condition; your scope has to mirror what they specify.
- Clients ask for it in tenders. Owners and EPC contractors in oil and gas, energy and infrastructure shortlist inspection agencies by accredited scope, and importers abroad want reports they can accept; under the Global ACI MRA, accreditation by one signatory is recognised by the others, except where regulation or law provides otherwise.
- Your in-house inspection department needs recognition. An inspection function serving its own organisation, or its organisation and outside clients, can be accredited as a Type non-A body, provided the impartiality risks of the relationship are identified, managed and shown to an assessor.
- You hold ISO 9001 and want inspection competence recognised. A quality certificate says your processes are managed, nothing about independence, inspector competence or the validity of a judgement. ISO/IEC 17020 adds those; an ISO 9001 system is a foundation for clause 8, not a substitute for accreditation.
Business benefits
How ISO/IEC 17020 accreditation supports your inspection body and its clients
Accreditation should win contracts and end arguments about the report. We start from the moments that cost inspection bodies money, a rejected report, a disputed finding, a lapsed qualification, and build the system around them.
- Reports that are acceptedA scope on the accreditation body's public schedule, recognised through the Global ACI MRA, so regulators, owners and importers accept your reports without a repeat inspection.
- Judgements you can defendDocumented methods, calibrated equipment and records showing what was examined, by whom and against which requirement, so a challenged finding has an answer and an appeal has a process.
- Independence stated, impartiality managedA declared Type A or Type non-A position and a live register of impartiality risks, so the relationship with the client or the parent organisation is handled openly, not discovered by the assessor.
- Inspectors whose competence is evidencedDefined competence per activity, qualification, authorisation and monitoring in the field, so competence is demonstrated rather than assumed.
- Consistency across inspectors and sitesOne method, one report format and one record set wherever the inspection happens, so two inspectors reach the same conclusion on the same item.
- A scope that can growMethods, competence files and equipment records built to one pattern, so a new field of inspection is a scope extension, not a new project.
Measure what these priorities should change: reports amended after issue, complaints and appeals, repeat inspections, lapsed authorisations, overdue equipment. A longer procedure is not a result.
Requirements
What are the main ISO/IEC 17020 requirements?
ISO/IEC 17020:2026 is organised in five requirement clauses, 4 to 8, followed by a normative Annex A on independence and an informative Annex B on optional elements of inspection reports and certificates. Clauses 4 to 7 concern the body and its inspection work; clause 8 is the management system behind them. The table is a plain-language map; the programme checks your body clause by clause, and the process clauses inspection type by inspection type.
| Clause | What it requires of you | What it looks like in practice |
|---|---|---|
| 4 General requirements | Operate impartially, identify risks to impartiality on an ongoing basis and show how each is eliminated or minimised, and keep information obtained during inspection confidential | A top-management commitment to impartiality, a risk register covering ownership, commercial pressure, other services and personal relationships, with actions and review dates, and confidentiality undertakings from everyone who sees client information |
| 5 Structural requirements | Declare the body's level of independence as Type A or Type non-A against Annex A, be a legal entity with adequate provision for its liabilities, and define an organisation with the management, technical responsibility and authority to perform inspection | An independence statement with its evidence, registration and insurance documents, an organisation chart, job descriptions, and a technical manager with a nominated deputy |
| 6 Resource requirements | Have access to enough competent personnel, define the competence needed, qualify, authorise and monitor inspectors, provide suitable facilities and equipment, calibrate measuring equipment with traceability where the result depends on it, and control externally provided products and services, including subcontracting | Competence criteria per activity, training and authorisation records, in-field monitoring of each inspector, an equipment register with calibration and in-service checks, controls on the technology used, and evaluated subcontractors and suppliers |
| 7 Process requirements | Review requests, tenders and contracts; apply documented inspection methods and procedures, including any non-standard method; identify and handle the items inspected; keep inspection records that let the inspection be evaluated; control data and information; issue an inspection report or certificate with the required content; and handle appeals and complaints through defined processes | Contract review records, a procedure per type of inspection with checklists and acceptance criteria, item identification and handling rules, records and site notes tied to each report, information systems with access control and backup, report templates with every mandated element, and an appeals and complaints register |
| 8 Management system requirements | Run a management system that supports clauses 4 to 7: policies and responsibilities, documented information and its control, actions to address risks and opportunities, corrective action, internal audits and management review | A concise management system in Effivity: controlled procedures and records, the risks and opportunities register, an audit programme that reaches the field, corrective actions closed with evidence and management reviews that decide |
What does useful ISO/IEC 17020 evidence look like?
An impartiality risk register with actions, the independence statement and its evidence, competence criteria and authorisations per inspector with monitoring records, calibration certificates and in-service checks, documented methods with completed checklists, item records, reports that match the records behind them, appeals and complaints files, and audit and management review records that show decisions. We identify the records each type of inspection genuinely needs and keep the management system records in Effivity from the first workshop, so the assessor sees a working body, not a binder.
ISO/IEC 17020 requirements explained, clause by clauseAccreditation process
How do you get ISO/IEC 17020 accredited?
Build an inspection body that meets the standard and can demonstrate it in the office and in the field, then apply to an accreditation body, which assesses you and decides. Sterling provides consulting and preparation; the decision belongs to the body, which is what makes the schedule worth having. Every body publishes its own procedure; the steps below are common to all.
- 01Define the scope, the independence type and the body.Agree which fields and types of inspection, items, methods or schemes and locations go on the application, decide Type A or Type non-A, and choose the accreditation body, normally the national one, checking its Global ACI MRA signatory status for inspection.
- 02Gap analysis: review the body against clauses 4 to 8 and Annex A, inspection type by inspection type.It covers impartiality and independence, structure, personnel, equipment, methods, records, reports, appeals, complaints and the management system, keeps what works and fixes actions, owners, dates and resources.
- 03Document the methods and build the evidence.Write the procedures, define and record inspector competence, authorise each inspector, bring calibration and in-service checks up to date, put the report templates into use and let records accumulate.
- 04Audit in the field, review, and close what is found.An internal audit that includes inspections observed on site, then a management review; findings are raised by us first and closed with evidence before the application goes in.
- 05Complete the accreditation body's assessment.Application and document review, a pre-assessment where offered, then the assessment at your premises and on site: assessors interview inspectors, sample records and witness inspections; nonconformities are closed by the body's deadline and its decision-makers grant the scope.
- 06Maintain the accreditation.Inspector monitoring, internal audits and management reviews continue, the body returns for surveillance, normally each year and with inspections witnessed again, and reassesses on the cycle it sets.
Establish who will accredit you before you compare prices. Only accreditation bodies operating to ISO/IEC 17011 accredit inspection bodies; a certificate of "ISO 17020 compliance" from a certification body or a consultancy is not accreditation and will be on no register. Before signing, ask which accreditation body it is and find it on the Global ACI list of recognised bodies. How to choose a credible ISO/IEC 17020 provider · The accreditation buyer's checklist
Cost
How much does ISO/IEC 17020 accreditation cost?
There is no list price for ISO/IEC 17020 accreditation: a four-inspector firm needs a different programme from a multi-country agency with six fields of inspection, and the accreditation body charges for the assessor days and witnessed inspections your scope needs. What we do promise is a proposal with every component visible and Sterling's fee fixed.
| Cost component | What affects it |
|---|---|
| Consulting and implementation | Current maturity, the fields and types of inspection in scope, the independence type and its impartiality work, locations, deliverables and how much of the work your team takes on (Design™ or Drive™) |
| Accreditation body fees | Application, document review, assessor days at your premises and for witnessed inspections, travel, and the body's annual and surveillance charges |
| Technical investment | Calibration of measuring equipment by accredited providers, inspector qualifications a scheme or regulator specifies, the standards you inspect against, and any equipment the methods need |
| Internal resources | Inspector and technical manager time for methods, competence records and witnessed inspections, management involvement, training and change |
| Software and learning | Included in a Sterling engagement: Effivity for the management system and Sterling Academy access for your people, with users, courses and access period confirmed in the proposal |
| Continued support | Internal audits, surveillance readiness, scope extensions, refresher learning and future changes under Sustain™ |
What moves the price
- The fields and types of inspection on the scope: each needs a method, competent inspectors and assessor time
- Locations and countries, and whether inspections are witnessed at one site or many
- Type non-A applications, where the impartiality case takes more work than for an independent body
- The state of equipment calibration and inspector records today
- Any existing ISO 9001 or ISO/IEC 17025 system, and the deadline a regulator, a client or the 2029 transition has set
What a Sterling proposal always shows
- Deliverables, responsibilities, assumptions and exclusions set out in writing
- Accreditation body fees shown separately, so you can compare the whole programme cost
- Effivity, training and Academy access itemised, at no additional cost
- Payment milestones linked to deliverables rather than dates
- One all-inclusive proposal. No surprises, ever
Timeline
How long does ISO/IEC 17020 accreditation take?
Plan on five to ten months for a first accreditation. Three things set the pace and none can be rushed: inspectors have to be authorised and then monitored on real inspections before the records prove anything; the body has to witness inspections, which means fitting its assessors around your clients' schedules; and its queue, document review, findings closure and decision take time you do not control. We plan around those dependencies and track the milestones in Effivity.
| Phase | What determines the pace |
|---|---|
| Scope and gap analysis | Access to inspectors, procedures, equipment and client records, and how quickly the scope and independence type are settled |
| Build and implementation | The number of methods to document, inspectors to qualify and authorise, equipment to calibrate, and the workload of the people doing it alongside client work |
| Evidence and review | Inspections under the new procedures so that records, monitoring and reports accumulate, then internal audit and management review |
| Accreditation assessment | The body's queue, assessor availability, the scheduling of witnessed inspections, the deadline for closing findings and the decision date |
If a regulator, a tender or the 2029 transition has set a date, share it at the start. We will say what is achievable, which inspections to schedule for witnessing and where an early scope decision saves months. A date offered before anyone has looked at your methods is not a plan.
The operations manager reports that implementation gave the company a more structured approach to its inspection activities, with better process consistency, documentation control and operational effectiveness, and a clear framework for competence management and continual improvement.
Challenges
Common ISO/IEC 17020 implementation challenges
Most inspection body programmes stall on the same five points, independence first. Each has a practical answer.
The independence type is unclear, or the body is less independent than it believes.
Ownership by a manufacturer, a parent that also maintains the items, inspectors who consult on the side. We work through Annex A with management, decide Type A or Type non-A on the evidence, restructure where the relationship must change and document the impartiality risks and controls for the rest.
Inspectors are experienced but their competence is undocumented.
Years in the field, no criteria and no records. We define the competence needed for each type of inspection, capture the qualifications and experience that exist, authorise each inspector for specific activities and set up monitoring, including observed inspections, that keeps authorisations current.
Methods live in the inspector's head.
Each inspector has a way of doing it. We write the procedure for each type of inspection with the standard, checklist and acceptance criteria, agree how non-standard methods are handled, and train the team to the same document.
Equipment is calibrated late, or not at all.
Gauges with no calibration status, unaccredited certificates, no in-service checks. We map which measurements affect the result, place calibrations with accredited providers, set in-service checks between them and bring the technology used during inspection under control.
Reports do not match the records behind them.
Reports written from memory, site notes discarded, amendments without a trail. We define the record set for every inspection, redesign the report and certificate templates around the required content, control data and information in your systems and set an amendment process, so any report traces back to what was seen.

How we deliver
How Sterling supports your ISO/IEC 17020 implementation
Every ISO/IEC 17020 engagement runs on Sterling OS™, our delivery operating system: five phases, each with named deliverables, decision owners and the evidence expected at its end. Choose the level of support your team has capacity for; the method, software and accountability stay the same.
- 01Design™Guided implementation: your inspectors and managers document, decide and record with Sterling's structure, templates, workshops and coaching.
- 02Drive™Fully managed consulting: Sterling consultants take on the agreed documentation, impartiality analysis and evidence build with your process owners.
- 03Sustain™Post-accreditation operation: surveillance readiness, internal audits, inspector monitoring, refreshers and new-inspector training, every year.
- 04Automate™The management system running in Effivity: documents, records, competence, equipment and calibration, impartiality risks, appeals and complaints, audits, actions and management review in one workspace.
- 05Revise™Scope extensions, new locations, changes in regulation, schemes or the body's requirements, and the move from the 2012 to the 2026 edition.
The engagement team, the weekly session, the deliverables and the decision owners are named before work starts and progress is reviewed against them, so an inspector who cannot be authorised in time is visible in month two, not in the assessment report.

Effivity · ISO/IEC 17020 management system software, included in every engagement
How Effivity helps you fulfil, automate and simplify the requirements of ISO/IEC 17020:2026.
Every Sterling ISO/IEC 17020 engagement includes Effivity, the ISO and GRC automation platform built by the Sterling group and used in 50+ countries. Its modules cover the management system, the part of ISO/IEC 17020 that most often slips between assessments: documents, records, competence and authorisations, equipment and calibration, subcontractors, impartiality risks, appeals, complaints, audits and management review. Your consultant configures the workspace within the agreed scope; inspection reports and site records stay in your own systems and are linked or attached as evidence, so the assessor sees one connected system. The subscription is included with the engagement, at no additional cost.
Impartiality risk register and confidentiality undertakings
Risks to impartiality identified on an ongoing basis, each with its source, owner, controls and review date, and confidentiality undertakings per person, so clause 4 is a living register, not a paragraph in the manual.
Independence statement, roles and responsibilities
The declared Type A or Type non-A position with its evidence, the organisation structure, the technical manager and deputy, and the responsibilities for each inspection activity, kept current as the body changes.
Competence, authorisation and monitoring records
Competence criteria per type of inspection, qualifications, training, each inspector's authorisation for specific activities and the monitoring record behind it, linked to Sterling Academy, so the authorisation matrix is a report, not a reconstruction.
Equipment register, calibration and in-service checks
Every instrument with its identification, location, calibration status, due dates, certificates and in-service checks, so an overdue calibration is flagged before it goes on site.
Subcontracted inspection, calibration and suppliers
Requirements, evaluation, approval and re-evaluation records for subcontracted inspection, calibration providers and suppliers, with their accreditation evidence attached.
Report control and amendment trail
Report and certificate templates with the mandated content, approval by authorised personnel, links from every report to the records behind it and a controlled amendment process, so any report can be traced to what was seen.
Appeals, complaints and corrective action
Received, acknowledged, investigated, decided by people not involved in the inspection concerned and closed with root cause and evidence, visible to management before they become a pattern.
Documented information, risks, audits and management review
Controlled documents and records with versions, approvals and retention, the risks and opportunities register, corrective actions tracked to closure, an audit programme that reaches the field, and a management review that records its inputs and decisions.
What this means at the assessment
The assessor asks for the authorisation record of the inspector about to be witnessed, the calibration status of the gauge in the van, the impartiality review for the client being visited and the complaints received since the last visit. In Effivity each answer is a screen, with dates, owners and attachments, not a binder compiled for the visit; after accreditation, Sustain™ continues in the same workspace.

- 01Read the case study
Inspection body: consistent inspections and ISO/IEC 17020 accreditation
An inspection body needed consistent inspections and reports, and a way to show clients its impartiality and competence. Working to ISO/IEC 17020 standardised its inspection procedures and produced detailed, accurate reports, reducing misunderstandings with clients. Accreditation gave evidence of impartiality and competence, reduced exposure to conflicts of interest and strengthened its reputation; its chief executive said the change went beyond a certificate to the way the organisation inspects, and that clients can see it.
Sterling Academy · ISO/IEC 17020 e-learning
Train every inspector on ISO/IEC 17020, not only the quality manager.
An assessor witnesses inspectors at work, not the quality manual. Sterling Academy provides e-learning for everyone who performs, reviews or reports an inspection and for those who run the system: video lessons with practice checkpoints, a final exam and a numbered Certificate of Completion, verifiable online, which serves as training evidence in competence records. Sterling consulting clients benefit from preferential course access and special pricing through their Sterling consultant, including complimentary awareness training for their people as part of the engagement.
- ISO/IEC 17020 awareness for every inspector and the office team, with the training record competence files need
- Practitioner courses for the quality manager, the technical manager and the owners of inspection methods
- Internal auditor training for the people who will audit the body, as applicable to your standard, as part of the engagement
- Learner progress by section and a training status report for the assessor
- New inspectors trained as they join, so records are current at each surveillance
- A Sterling consultant reachable when a learner needs one

Why Sterling
Want successful ISO/IEC 17020 accreditation? Come to Sterling.
Whether you are accrediting one inspection office or bringing inspectors in several countries onto one system, Sterling helps you settle independence accurately, evidence competence properly and build a management system your inspectors will keep using as the scope grows.
Inspection bodies supported in 60+ countries
Management system consulting across sectors and countries since 2003, with one engagement team accountable wherever your inspectors work.
All-inclusive proposal
Consulting, Effivity, training and Academy access in one proposal, accreditation body fees shown separately. No surprises, ever.
A system your inspectors will use
Less documentation and maximum effectiveness: methods, records, training and software connected to the inspection itself, so inspectors adopt the system instead of working around it.
Expert and experienced consultants
Consultants who have prepared inspection bodies for accreditation across sectors and countries, building the impartiality case and the competence evidence properly the first time, so the assessment confirms what works.
The Sterling Promise
What our ISO/IEC 17020 accreditation success guarantee means
We stay with you until the ISO/IEC 17020 accreditation outcome agreed in your engagement is achieved, through consulting, assessment preparation and the resolution of the assessors' findings. Plain explanations, practical delivery, included software and staff learning turn the investment into a capability the body keeps.
The engagement identifies the standard, the scope applied for, the independence type, the outcome and the responsibilities. Your body supplies accurate information, performs the agreed inspections and monitoring, and puts the controls into use. The independent accreditation body assesses competence and keeps the decision. Our commitment is the agreed accreditation support, not a promise that every regulator or client will accept every report.
After accreditation
What happens after ISO/IEC 17020 accreditation?
Accreditation is a cycle, not a certificate. The body returns for surveillance, normally each year and with inspections witnessed again, and for a full reassessment on the cycle it sets; UKAS confirms accreditation annually and reassesses every fourth year, EIAC runs a three-year cycle. Between visits the inspection body keeps monitoring inspectors, calibrating equipment, auditing and reviewing the system, and reports significant changes as required.
Under Sterling OS™ Sustain™ we review appeals, complaints, monitoring results, calibration status and impartiality risks with you alongside internal audits, management reviews and surveillance preparation, and prepare scope extensions.
FAQs
Frequently asked questions about ISO/IEC 17020
Is ISO/IEC 17020 a certification or an accreditation?
An accreditation. An accreditation body assesses competence, impartiality and consistent operation for a defined scope, witnesses inspections and, if satisfied, grants and publishes the scope. Certification bodies certify management systems; they do not accredit inspection bodies, and a "17020 certificate" from one is not accreditation.
What are Type A and Type non-A inspection bodies, and what happened to Type B and Type C?
The 2026 edition categorises inspection bodies as Type A or Type non-A by their level of independence, replacing Type A, B and C; the requirements sit in clause 5.1 and the normative Annex A, and impartiality applies equally to both. Under the 2012 edition, Type A was the independent third party, Type B a body inspecting only for its parent organisation and Type C one inspecting for its parent and others. A body accredited as Type B or C should not assume its position carries over; it reassesses against the new annex during the transition.
Which accreditation body should we apply to, and will our reports be accepted abroad?
Normally the national body, for example PAB (Philippines), NABCB (India), UKAS (United Kingdom), EIAC (Dubai), GAC (Gulf states), ANAB or A2LA (United States), NATA (Australia) or SAC (Singapore), provided it is a Global ACI MRA signatory for inspection. Signatories recognise one another's accreditations as equivalent, except where regulation or law provides otherwise, so check the register and ask whoever will receive the report.
We are already accredited to ISO/IEC 17020:2012. What do we have to do, and by when?
Transition to the 2026 edition before your accreditation body's deadline. The internationally agreed period is three years from publication, which accreditation bodies have published as 27 March 2029, and they are already assessing to the new edition: UKAS from 1 September 2026, with the 2012 edition no longer assessed from 1 January 2028. Bodies also apply ILAC P15:05/2020, written for the 2012 edition; ask yours how it applies during the transition. Expect a gap analysis against the new text, changes to the impartiality register, the independence statement, data control and the system documents, then a transition assessment.
Does ISO 9001 certification satisfy ISO/IEC 17020?
No. ISO 9001 addresses the quality management system; ISO/IEC 17020 adds impartiality and independence, inspector competence, equipment, methods, records, reports and appeals, assessed with inspections witnessed. An ISO 9001 system is a good base for clause 8, but clauses 4 to 7 still have to be implemented and demonstrated.
What is a scope of accreditation for an inspection body, and can we extend it?
The scope lists the fields and types of inspection, items, methods or schemes and locations the body has been assessed for; only inspections within it may be reported as accredited. Extending it is routine: the method is documented, inspectors authorised, equipment controlled, and the body assesses the extension, usually with a witnessed inspection.
Do assessors really witness inspections, and what do they look at?
Yes. Witnessing is how competence is verified: assessors watch inspectors perform inspections from the scope, on site, compare what they see with the procedure and check that the report matches the records; the choice of inspections and inspectors is agreed with the assessment team, not left to you.
Does Sterling accredit inspection bodies or issue certificates?
No. Sterling's work is consulting and assessment readiness. An independent accreditation body assesses the inspection body, witnesses its work and decides. Anyone offering both the preparation and the accreditation is selling paper.
What do you need to prepare an ISO/IEC 17020 proposal?
The fields and types of inspection for the scope, the locations, the number of inspectors, the independence position, the equipment in outline, any existing system, the intended accreditation body and the deadline. That is enough for a scoped, all-inclusive proposal; no manual or procedures are needed first.
Before the first call
Prepare a useful ISO/IEC 17020 readiness brief
Bring a short account of what the body inspects, for whom, and where accreditation should help; no manual or procedures are needed yet. Seven questions suffice:
- Which fields and types of inspection do you want on the scope, at which locations, and who has asked for accredited reports: a regulator, a client or your own management?
- Is the body an independent third party, or part of an organisation that makes, supplies, owns, uses or maintains the items it inspects?
- Which standards, regulations, schemes or specifications do you inspect against, and are the methods documented today?
- How are inspectors qualified, authorised and monitored now, and what records exist?
- Which instruments affect your results, and when were they last calibrated, by whom?
- Does an ISO 9001, ISO/IEC 17025 or other system exist, and who can make decisions and give time to implementation and internal audit?
- Which accreditation body do you intend to apply to, and is there a deadline from a regulator, a tender or the 2029 transition?
These answers let us scope the work and price it realistically; they open a discussion, not a scored assessment or an accreditation decision.
Don’t be fooled by certification scams
If it takes ten days, it is not ISO/IEC 17020 accreditation.
Inspection body accreditation means something because an assessor watched your inspectors work and checked the report against what they saw. The market sells ways around that: "ISO 17020 certificates" from certification bodies, document sets sold as accreditation, and "assessments" without a witnessed inspection. They cost less, until a regulator looks for your scope on a register and finds nothing.
How to choose a credible ISO/IEC 17020 provider
- Ask which accreditation body will assess you, then find it on the Global ACI list of recognised bodies and read one of its published inspection schedules.
- Refuse any "ISO 17020 certificate" from a certification body. Certification bodies certify management systems or products; only an accreditation body working to ISO/IEC 17011 accredits inspection bodies.
- Ask how independence will be decided and impartiality evidenced. A provider who cannot explain Type A and Type non-A has not read the 2026 edition.
- Identify who carries each task, which body and calibration fees are separate, and what support exists when findings need closing.
- Ask what your inspectors will learn and where the records will live. Without training and a system, the competence evidence stops when the consultant leaves.
- Walk away from "accredited in 7 to 10 days", "no witnessed inspection" and one invoice for consulting and accreditation. A body has to operate, be audited and be witnessed first.
