What moves the price
- Which standard — ISO 27001 information security costs more than ISO 9001 quality or ISO 14001
- Business size — more staff and processes mean more consultant days and audit time
- Number of sites — each site adds visits for the ISO consultant and the auditor
- Starting point — little existing documentation means more consultant days
- Accredited or not — UKAS-accredited certification costs more than a non-accredited certificate
- Ongoing audits — annual surveillance audits add a yearly ISO certification cost
Professional services prices in the UK are up 12% over five years (ONS Consumer Price Inflation, Other services n.e.c., to 2026 August). Five years ago a typical iso certification consultant would have cost about £5350 — an estimate from today's guide price and that index, not a recorded price. Source: ONS MM23 D7FR →

How to pay less
- Use existing procedures where possible so the ISO consultant writes less from scratch
- Choose the standard your customers actually ask for before adding others
- Keep the ISO scope to the sites and services your customers ask about, which keeps the consultant's days down
Before you book
- Check whether tenders require UKAS-accredited ISO certification before choosing a route
- Ask the ISO consultant how many days of support the fee includes
- Budget for annual surveillance audits on the three-year certification cycle
- Remember the certification body cannot advise you, so consultancy is a separate service
ISO Certification Consultant cost: questions people ask
£2,000–£11,000 per project, with about £5,000 typical for a small business. A micro business on ISO 9001 costs the least; ISO 27001 or several sites cost the most.
Three to twelve months, depending on the size of the business and how much is already in place.
Often, yes. Many public and large-company tenders require certification from a UKAS-accredited body, not just any certificate.
No. Certification bodies cannot advise you on how to meet the standard, which is why many businesses use a consultant.
Certification body audit fees, annual surveillance audits and software tools are often separate.
