The London economy
Certification shaped around London businesses
The City of London and Canary Wharf anchor banking, insurance, asset management and the legal and accountancy firms that serve them. Technology and digital businesses cluster around Shoreditch and King's Cross, where Google and other large employers have offices close to life sciences institutions such as the Francis Crick Institute. Central government departments, Transport for London and the NHS are major buyers of services, while large construction and infrastructure programmes sustain an extensive contractor and facilities management supply chain. Creative industries, hospitality, logistics and data centre operations add further breadth, and many London firms handle sensitive client data that places information security at the centre of supplier due diligence.
Suppliers to central government, Transport for London, NHS trusts and regulated financial firms are often asked for ISO 27001 and ISO 9001 at tender stage, and many buyers now ask for evidence of business continuity planning as well.

ISO standards for London organisations
The first tabs show the standards London organisations ask for most often. Every standard is available locally, on site.
Information & Technology
ISO/IEC 27001:2022Information Security Management
ISO/IEC 27001:2022 specifies requirements for an information security management system (ISMS). It requires an organisation to assess information security risks to the confidentiality, integrity and availability of information, select controls to treat them and manage those controls through a continual cycle of monitoring and review. Annex A lists 93 reference controls in four themes: organisational, people, physical and technological. Each organisation compares its chosen controls against Annex A and records the outcome in a Statement of Applicability.
- Answer security questionnaires
- Risk-based security
- Supports data protection duties
- Management oversight
Quality
ISO 9001:2026Quality Management
ISO 9001:2026 sets out the requirements for a quality management system. Published in September 2026, it replaces ISO 9001:2015 and keeps the same core approach. It asks an organisation to understand its context and interested parties, plan its processes around risks and opportunities, and show that it consistently provides products and services that meet customer and applicable statutory and regulatory requirements. It is the most widely used management system standard and applies to organisations of any size or sector, from sole manufacturers to national service providers.
- Meet tender and supplier requirements
- Consistent processes
- Fewer errors and complaints
- Risk-based planning
Resilience & Governance
ISO 22301:2019Business Continuity Management
ISO 22301:2019 specifies requirements for a business continuity management system (BCMS). It helps an organisation prepare for, respond to and recover from disruptive incidents when they occur. The core of the standard sits in clause 8, which requires a business impact analysis and risk assessment, business continuity strategies and solutions, documented plans and procedures, an exercise programme and evaluation of business continuity capability. It follows the Harmonized Structure and integrates with other management system standards.
- Evidence for customers
- Clear recovery priorities
- Tested plans
- Understanding dependencies
Information & Technology
ISO/IEC 42001:2023Artificial Intelligence Management
ISO/IEC 42001:2023 is the first international management system standard for artificial intelligence. It specifies requirements for establishing, implementing, maintaining and continually improving an AI management system (AIMS) within an organisation that develops, provides or uses AI systems. It requires AI risk assessment, AI risk treatment and AI system impact assessment, considering effects on individuals, groups and society. Annex A provides reference controls covering areas such as AI policy, resources, impact assessment, the AI system life cycle, data and third-party relationships.
- Evidence of responsible AI governance
- Structured risk and impact assessment
- Clear roles and accountability
- Life cycle controls
Environment & Energy
ISO 14001:2026Environmental Management
ISO 14001:2026, published in April 2026 to replace the 2015 edition, specifies the requirements for an environmental management system. It helps an organisation identify the environmental aspects of its activities, products and services, understand its compliance obligations, and manage significant impacts through planning, operational control and evaluation. The standard takes a life cycle perspective, so organisations consider stages they can control or influence, such as purchasing, transport, use and end-of-life treatment, as well as their own sites.
- Supply chain and tender credibility
- Structured legal compliance
- Control of significant impacts
- Resource and waste efficiency
Health & Safety
ISO 45001:2018Occupational Health and Safety Management
ISO 45001:2018 sets out requirements for an occupational health and safety management system. Its aim is to prevent work-related injury and ill health and to provide safe and healthy workplaces. The standard places strong emphasis on leadership, the consultation and participation of workers, hazard identification and the hierarchy of controls. It replaced OHSAS 18001 and follows the Harmonized Structure, so it integrates readily with ISO 9001 and ISO 14001.
- Prequalification and tenders
- Worker involvement
- Systematic hazard control
- Clear legal oversight
Environment & Energy
ISO 50001:2018Energy Management
ISO 50001:2018 specifies requirements for an energy management system (EnMS). It requires an organisation to understand how it uses and consumes energy, identify significant energy uses, set an energy baseline and energy performance indicators, and plan actions to improve energy performance. Unlike some other management system standards, ISO 50001 requires an organisation to demonstrate continual improvement in energy performance itself, not only in the management system.
- ESOS compliance route
- Measured energy performance
- Focus on significant uses
- Cost control
Sector-specific
ISO 22000:2018Food Safety Management
ISO 22000:2018 specifies requirements for a food safety management system for any organisation in the food chain, from feed and primary production through processing, storage, transport, retail and food service, as well as packaging and equipment suppliers. It combines the Harmonized Structure management system clauses with HACCP principles from Codex Alimentarius, prerequisite programmes (PRPs) and interactive communication across the food chain. The standard uses two linked Plan, Do, Check, Act cycles: one for the management system and one for operational hazard control.
- Structured hazard control
- Applies across the food chain
- Management system discipline
- Communication across the chain
Sector-specific
ISO 13485:2016Medical Devices Quality Management
ISO 13485:2016 specifies requirements for a quality management system where an organisation needs to demonstrate its ability to provide medical devices and related services that consistently meet customer and applicable regulatory requirements. It applies to manufacturers and to organisations involved in other stages of the device life cycle, such as design, distribution, installation, servicing, sterilisation and component supply. The standard places particular emphasis on risk management, process validation, traceability and regulatory reporting.
- Supports regulatory submissions
- Supply chain requirements
- Risk management throughout
- Validated processes
Information & Technology
ISO/IEC 20000-1:2018IT Service Management
ISO/IEC 20000-1:2018 specifies requirements for establishing, implementing, maintaining and continually improving a service management system (SMS). It covers the planning, design, transition, delivery and improvement of services to meet agreed requirements. Clause 8 sets out the operational processes, grouped into service portfolio, relationship and agreement, supply and demand, service design, build and transition, resolution and fulfilment, and service assurance. The 2018 edition follows the Harmonized Structure, which allows integration with ISO/IEC 27001 and ISO 9001.
- Procurement credibility
- Consistent service delivery
- Clear service agreements
- Controlled change
Resilience & Governance
ISO 37001:2025Anti-Bribery Management
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.
- Supports adequate procedures
- Risk-based controls
- Due diligence on third parties
- Clear governance oversight
Why it matters locally
What certification does for a London business
Win and keep contracts
Public bodies and larger buyers advertising on Find a Tender and Contracts Finder frequently ask for certified management systems at pre-qualification. A certificate answers those questions with independent evidence.
Show control to regulators
Organisations in Greater London answer to the Health and Safety Executive (HSE) and the Environment Agency. A certified system demonstrates that risks, legal duties and incidents are managed systematically.
Strengthen supply chains
For financial and professional services and technology and digital suppliers, certification reduces repeated customer audits and questionnaires, and makes onboarding faster.
Run a better business
Clear processes, measured objectives and regular internal audits help teams across London work consistently, reduce errors and improve year after year.

FAQs
ISO certification in London: FAQs
Do you carry out ISO certification audits in London?
Yes. Hexa Certifications audits organisations in London and across Greater London, including Croydon, Stratford, Canary Wharf, Wembley. Stage 2, surveillance and recertification audits are normally carried out on site at your premises, with some Stage 1 and document review activity completed remotely where the scheme rules allow it.
Which ISO standards are most requested by London businesses?
Demand follows the local economy. In London we most often see interest in ISO 27001, ISO 9001, ISO 22301, ISO/IEC 42001, reflecting sectors such as financial and professional services, technology and digital, construction and infrastructure. Many organisations combine two or three standards into one integrated audit to save time on site.
How long does ISO certification take for a company in London?
Timescales depend on how ready your management system is, rather than where you are based. An organisation that has run its system for a few months, completed an internal audit and held a management review can usually move from Stage 1 to a certification decision within six to twelve weeks of booking.
Will the auditor visit our site in London?
Yes. Certification audits need objective evidence gathered where the work happens, so your auditor visits your London site for Stage 2 and for each surveillance audit. Travel is planned in advance and included in the fixed quotation you receive before you commit.
How much does ISO certification cost in London?
Audit fees are set by audit duration, which is calculated from your headcount, the number of sites, the standards in scope and the complexity of your activities. We do not charge a location premium for London. Request a quote and you will receive a fixed, itemised proposal covering the full three-year certification cycle.
Can you certify organisations with several sites around London?
Yes. Multi-site organisations can be certified under a single certificate where the sites operate under one management system with central control. We use sampling rules to decide which sites are visited at each audit, so a head office in London and branches elsewhere can be covered efficiently.
Does ISO certification help London companies win public sector work?
Often, yes. Many buyers using Find a Tender and Contracts Finder ask suppliers for evidence of quality, environmental, health and safety or information security controls. A current certificate is a clear, independently verified way to answer those questions and can shorten pre-qualification for local authority, NHS and prime contractor supply chains.
Do you help write our management system in London?
No. As an independent certification body we cannot design or write the management system we later certify, because that would compromise impartiality. We can carry out an optional pre-assessment that shows where you stand against the standard, and you remain free to use any consultant or in-house resource to close gaps.
