What ISO 14001 is
ISO 14001 sets out requirements for an environmental management system (EMS): identifying environmental aspects and legal obligations, setting objectives and monitoring performance.
Who needs it
Manufacturers, construction, logistics and any organisation whose customers or tenders ask for environmental management evidence. Offices are treated as lower complexity than heavy industry.
New edition. One certification body says ISO 14001:2026 was published in April 2026 and that organisations must transition before May 2029. Check the date with your certification body.
How certification works
Certification is carried out by an independent certification body. The usual shape is a first-stage audit that checks your documents and readiness, a second-stage audit that checks the system is working in practice, then a certificate valid for three years. In between, surveillance audits happen at least annually, and a recertification audit closes the cycle. The certification bodies we read describe the same cycle (three-year certificate, annual surveillance).

Choose the right certification body
Accreditation matters, and it is checked per standard and sector. GOV.UK says the UK national accreditation body is UKAS and that government only recognises UKAS accreditation of organisations operating in the UK. Read the checklist.
