ISO 9001 Certification Costs
When researching ISO certification, one of the first questions business owners ask is:
“How much does ISO certification actually cost?”
The simple answer is, it depends.
ISO 9001 certification costs vary based on several factors including your organisation’s size, number of sites, sector, and how much support you need to prepare for your audit. Whether you go it alone or partner with an experienced ISO consultant can also make a significant difference to both your costs and success rate.
In this detailed guide, we’ll break down every cost involved in ISO 9001 certification, including consultancy fees, audit charges, and ongoing maintenance costs. You’ll also learn how to reduce ISO costs without cutting corners and why investing in certification pays off in the long term.

What Is ISO 9001 Certification?
ISO 9001:2015 is the international standard for Quality Management Systems (QMS). It helps organisations establish structured, efficient, and customer-focused processes.
Businesses achieve ISO 9001 certification to:
- Improve quality and consistency
- Reduce waste and costly rework
- Increase customer satisfaction and retention
- Win new contracts and meet tender requirements
- Strengthen brand credibility and trust
To become certified, your business must:
- Undergo a two-stage audit by an independent UKAS-accredited certification body
- Design and implement a QMS aligned with ISO 9001:2015 requirements
- Maintain documented procedures and records
What Factors Influence ISO 9001 Certification Costs?
The cost of ISO certification is not fixed because every business is different. Several key factors influence the total investment:
| Factor | Impact on Cost |
|---|---|
| Certification Body Choice | UKAS-accredited bodies are more credible but typically charge higher fees than non-accredited providers. |
| Business Size | More employees and complex operations mean longer audits and more documentation to review. |
| Number of Sites | Each additional location requires audit time, increasing total costs. |
| Industry Risk Level | High-risk sectors (construction, manufacturing, aerospace) may require additional audit days. |
| Current Readiness | If you already follow structured processes, you’ll need fewer consultancy days than a business starting from scratch. |

Breakdown of ISO 9001 Certification Costs in the UK
Below is a transparent, realistic breakdown of the key cost components when budgeting for ISO 9001 certification.

Typical Costs:
- Small business: £500 – £1,500
- Medium/large business: £1,500 – £3,000+
Pro Tip:
A detailed gap analysis prevents wasted time later and can reduce consultancy hours overall.

What’s Included:

- Internal audits and management reviews
- System updates for new regulations
- Staff refresher training
- Document control or QMS software (optional)
Typical Ongoing Annual Costs: £1,000 – £3,000+
