What is ISO 45001 certification?
ISO 45001 is the international standard for occupational health and safety management systems, replacing the earlier OHSAS 18001 standard. UK businesses use it to demonstrate a systematic approach to reducing workplace injuries and ill health.
How long does ISO 45001 take to achieve?
ISO 45001 certification typically takes 3 to 6 months for a UK business with a consultant's help. Organisations in higher-risk sectors such as construction and manufacturing may require more time due to the complexity of their safety controls.
How much does ISO 45001 cost UK businesses?
ISO 45001 certification costs UK businesses between £4,000 and £15,000 in total. Construction and manufacturing firms with complex operational environments typically pay more due to the scope of controls required.
Do I still need OHSAS 18001 or has it been replaced?
OHSAS 18001 was formally withdrawn in 2021. All organisations previously certified to OHSAS 18001 should now hold ISO 45001. If your certification still references OHSAS 18001, it is no longer recognised and you should recertify to ISO 45001 immediately.
Is ISO 45001 a legal requirement in the UK?
ISO 45001 is not a legal requirement, but it provides a framework that helps UK businesses comply with the Health and Safety at Work Act 1974 and associated regulations. It is increasingly required in construction and manufacturing supply chains.
