How much does ISO 9001 certification cost in the UK?

The three costs

1. The certification body’s fees

The certification body (BSI, NQA, SGS and others) audits you and issues the certificate. Its fees are quoted per audit day, and the number of audit days depends on your headcount, the number of sites and the scope of what you make or do. Expect a quote for the initial certification audit (Stage 1 and Stage 2) and then for the surveillance audits in the years that follow. That fee is separate from anything we charge, and it is paid whether or not you use a consultant.

We do not quote a figure for it here: it is set per job by the body you choose. Ask two or three for a quote on the same information (headcount, sites and scope) so the numbers are comparable.

2. Consultancy, if you want it

Outside help is optional. What drives its cost is how far your current system is from the standard, how much of the work your own team will do, and whether you want someone to do the work or to check it. A business with working processes that are simply not written down needs far less than one starting from nothing.

3. Your own people’s time

The largest cost is often the one that never appears on an invoice: the time your quality lead, managers and operators spend on the system, the internal audits and the certification audits themselves. A consultant can reduce it; nothing removes it, because the system has to be yours.

ISO 14001 costs the same way
