What does ISO 9001 certification cost?
Prices last checked 23 August 2026
Less as a single number than as a three-year cycle, which is why the quotes look so different from each other.
ISO 9001: what decides the price
Certification bodies price on the number of employees and the number of sites, then split the work into an initial assessment in year one and a shorter surveillance visit in each of years two and three, so a figure quoted for the first year is not the annual cost. There are usually three separate bills rather than one: the certification body, any consultancy used to write the management system, and the training for whoever will run internal audits afterwards. ISO 9001 is not on the register of duties on this site, because everything in the duties section is there for a piece of legislation that requires it and ISO 9001 is not required by any. What creates the requirement in practice is a customer or a tender asking for it, and what they normally ask for is certification from a body accredited by UKAS. The Government recognises no other accreditation for organisations operating in the UK, so a certificate from an unaccredited body may not satisfy the tender that prompted it. Check that first, because it is the part that decides whether the money was worth spending.
