- Risk-based controls
- Due diligence on third parties
- Clear governance oversight

Overview
What is ISO 37001:2025?
ISO 37001 specifies requirements for an anti-bribery management system. It helps an organisation prevent, detect and respond to bribery, whether by the organisation, its personnel or business associates acting on its behalf, and bribery of the organisation. Requirements include an anti-bribery policy, top management and governing body oversight, an anti-bribery compliance function, bribery risk assessment, due diligence, financial and non-financial controls, gifts and hospitality controls, and processes for raising and investigating concerns. The second edition, ISO 37001:2025, was published in February 2025.
Hexa Certifications Limited provides independent third-party certification audits against ISO 37001. Our auditors review your bribery risk assessment, the proportionality of your controls and how they operate in practice, including due diligence on business associates and the handling of concerns. In line with ISO/IEC 17021-1 we do not write anti-bribery policies or procedures for clients. An optional pre-assessment is available if you want an independent view of readiness first.
In the UK, section 7 of the Bribery Act 2010 creates an offence for commercial organisations that fail to prevent bribery by associated persons, with a defence where the organisation had adequate procedures in place. The Ministry of Justice guidance sets out six principles, which ISO 37001 covers closely. Certification can form part of the evidence of adequate procedures, but it does not guarantee the defence, which is a matter for the courts.

Benefits
What ISO 37001 certification does for you
Supports adequate procedures
ISO 37001 covers the areas set out in Ministry of Justice guidance on the Bribery Act 2010, helping you build and evidence proportionate procedures to prevent bribery.
Risk-based controls
A documented bribery risk assessment directs controls towards the transactions, projects, jurisdictions and business associates where risk is highest, rather than applying the same controls everywhere.
Due diligence on third parties
Requirements for due diligence on business associates and personnel in higher-risk roles help you understand who you work with and set appropriate controls before entering relationships.
Clear governance oversight
The governing body and top management have defined responsibilities, supported by an anti-bribery compliance function with appropriate authority, resources and independence to oversee the system day to day.
Speak up and investigation
Processes for raising concerns in confidence without fear of reprisal, and for investigating and dealing with bribery, help issues surface early and be handled consistently.
Integration with compliance systems
The 2025 edition uses the Harmonized Structure, so it integrates readily with ISO 37301 compliance management, ISO 9001 and ISO/IEC 27001 through shared management system processes.

Application and quotation
You tell us your scope, sites, headcount and standards. We calculate audit duration using the accreditation rules and send a fixed quotation for the full three-year cycle.
- 2
Stage 1 audit
Your auditor reviews your documented information, scope, legal and regulatory awareness, internal audit and management review, and confirms you are ready for Stage 2.
- 3
Stage 2 audit
An on-site evaluation of how your management system works in practice. The auditor interviews people, observes activities and samples records against every requirement.

Certification decision
Any nonconformities are closed with evidence. A qualified reviewer who did not take part in the audit makes the certification decision and your certificate is issued.
- 5
Surveillance and recertification
Surveillance audits take place at least once a year to confirm continued conformity. A recertification audit before the third anniversary renews your certificate.

FAQs
ISO 37001 certification questions
Answers about scope, timing and audits for ISO 37001:2025.
Does ISO 37001 certification give us a defence under the Bribery Act 2010?
Not automatically. Section 7 of the Act provides a defence if an organisation had adequate procedures to prevent bribery by associated persons. Certification shows that an independent body has assessed your anti-bribery system against ISO 37001, which can form part of the evidence of adequate procedures. Whether the defence succeeds is decided by the courts on the facts of each case.
What changed in ISO 37001:2025?
The second edition was published in February 2025, replacing the 2016 edition and its 2024 climate change amendment. Changes reported include greater emphasis on anti-bribery culture, clarification of the anti-bribery compliance function, and alignment with the current Harmonized Structure, including consideration of climate change under clause 4.1. Organisations certified to the 2016 edition will need to transition.
How long do we have to transition from ISO 37001:2016?
Transition periods for new editions are set by the accreditation community and normally run for a defined period from publication, during which certificates to the older edition remain valid. We will confirm the applicable deadline and plan a transition audit, usually alongside a surveillance or recertification visit. Contact us to discuss timing for your organisation.
Does ISO 37001 cover fraud or wider corruption?
ISO 37001 specifically addresses bribery. It does not cover fraud, money laundering, competition law or other forms of corruption, although many of its controls overlap with them. Organisations wanting a broader compliance framework often use ISO 37301 compliance management systems alongside it. Separate legal obligations, such as UK failure to prevent fraud rules, need their own consideration.
What is the anti-bribery compliance function?
It is the person or people with responsibility and authority to oversee the design and implementation of the anti-bribery management system, advise personnel, and report to top management and the governing body. It must have adequate resources, competence, status and independence. In smaller organisations it can be a part-time role held by someone with other duties.
Do we need to carry out due diligence on every supplier?
No. Due diligence must be proportionate to the bribery risk assessed. Lower-risk business associates may need little or no due diligence, while agents, intermediaries, joint venture partners or suppliers in high-risk jurisdictions need more detailed checks. Your risk assessment should explain how you decide the level of due diligence for each category.
Can a small organisation achieve ISO 37001 certification?
Yes. The standard is designed to be applied proportionately according to size, structure, sector, jurisdictions and the nature of bribery risks. A small business with limited international activity will have simpler controls than a multinational contractor. Auditors assess whether your measures are reasonable and proportionate for your circumstances, not whether they match those of larger organisations.
Can Hexa write our anti-bribery policy or risk assessment?
No. ISO/IEC 17021-1 prevents certification bodies from designing or implementing the systems they certify. You can develop your anti-bribery management system internally, with legal advisers or with an independent consultant. We can offer an optional pre-assessment that gives an impartial view of readiness against ISO 37001.
