How much will it cost to become certified?

It is advisable to employ the services of a consultant to guide the implementation process and ensure that the work you put in is in line with the requirements of the standard. Audit assessment fees tend to be calculated on your business' annual turnover. For example for a company turning over up to £250k fees are likely to be in the region of £1000 - £2000 and for a company £2.5M to £5M probably in the region of £3000 - £5000.
