ISO 45001 Certification Support

Winning bigger contracts and tenders increasingly means having ISO 45001 in place. We handle the gap analysis, documentation and audit preparation so you go into certification ready — not guessing.

ISO 45001Certification
Support
Worth knowing before you start: Crestfield Safety provides consultancy and preparation support — we don't issue ISO 45001 certificates ourselves. Certification is granted by an independent, UKAS-accredited certification body following their own audit. Our job is to get your management system, documentation and evidence genuinely ready so that audit goes smoothly the first time.
Why it matters

Not a legal requirement — increasingly a commercial one

Unlike a fire risk assessment, ISO 45001 certification isn't a legal duty. It's a voluntary, internationally recognised standard for occupational health and safety management systems. In practice, though, it's become a gatekeeper: more principal contractors, public sector buyers and larger clients now require it, or score it heavily, in tender and procurement processes.

Businesses without it can find themselves excluded from opportunities before price is even discussed. Certification also tends to reduce insurance premiums, lower incident rates, and give you a management system that keeps working even as you grow, rather than relying on one person's knowledge.

Good fit if you
  • Are being asked for ISO 45001 by a client or principal contractor
  • Want to strengthen tender submissions against larger competitors
  • Already have some H&S documentation but nothing formally certified
  • Are scaling and want a management system that doesn't rely on one person
  • Hold ISO 45001 already and need support maintaining it through surveillance audits

Common questions

ISO 45001 FAQs

What is ISO 45001?

ISO 45001:2018 is the international standard for occupational health and safety management systems. It sets out a framework for identifying and controlling risk, meeting legal requirements, and continually improving safety performance, with certification issued by an independent, accredited certification body.

Do we legally need ISO 45001?

No — it's a voluntary standard, not a legal requirement. However, many clients, principal contractors and public sector buyers now require or heavily favour suppliers who hold it, which makes it a commercial necessity in some sectors even though it isn't a legal one.

How long does certification typically take?

It depends on your starting point. A business with some documentation already in place might be ready in a few months; one starting from scratch usually takes longer to build and embed a genuinely working management system before it's ready for audit.

How much does it cost?

Support is scoped and priced after a short call, based on your headcount, current documentation and how much work is needed — that keeps it fair to your actual starting point rather than a flat fee. The certification body's own audit fee is separate and paid directly to them.

Do you issue the ISO 45001 certificate?

No. We provide consultancy and preparation support to get your management system and evidence audit-ready. The certificate itself is issued by an independent, UKAS-accredited certification body after their own Stage 1 and Stage 2 audits.
