The Real Cost of ISO 9001 Accreditation: What Businesses Need to Know
David Preston • 12 September 2025
Whether you are well established or a new business, you want a fair price.

ISO 9001 is the world’s most recognised quality management standard, providing a framework for organisations to consistently meet customer expectations and regulatory requirements. For many businesses, achieving ISO 9001 accreditation is a strategic decision that signals credibility, competitiveness, and commitment to quality.
But one of the first questions organisations ask is: how much does ISO 9001 accreditation cost?
The cost depends on several factors – from the size and complexity of your organisation to the certification body you choose. At Genersol, we help businesses navigate this journey in a way that is both cost-effective and aligned with long-term goals. We believe that you get what you pay for. There are organisations out there who offer very cheap, unaccredited services - we do not work with this category. If the certifying body is not UKAS accredited then the certificate isn't worth the paper it is written on (more on that below).
Key Factors That Influence ISO 9001 Costs
1. Size of Your Organisation
Certification bodies typically charge based on the number of employees. A small business with under 25 staff will naturally have fewer audit days required than a large manufacturer with several hundred employees spread across multiple sites.
2. Complexity of Processes
Not all organisations are equal in how complex their operations are. For example:
- A service-based SME with straightforward processes may require a lighter audit.
- A multi-site engineering firm with regulated processes, subcontractors, and international supply chains will face higher costs due to the depth of assessment required.
3. Number of Locations
Each additional site usually adds audit time and cost, as auditors must confirm that quality systems are applied consistently across the business.
4. Certification Body Choice
This is one of the biggest variables.
Top-tier providers like BSI (who Genersol hold our certification with), LRQA, or SGS are globally recognised, carry strong reputations, and are often preferred by organisations with international customers or supply chain requirements. They typically come at a higher cost.
Less well-known providers can offer significantly lower fees. For some organisations, especially SMEs serving local markets, this is a perfectly valid route to certification.
Why UKAS Accreditation Matters
In the UK, the United Kingdom Accreditation Service (UKAS) is the government-appointed body that oversees certification bodies. A certificate issued by a UKAS-accredited provider carries weight because it guarantees that the certification process itself has been independently verified.
- UKAS-accredited certificates are widely recognised, often required in tendering or supply chain contracts.
- Non-UKAS certificates may not be accepted by customers, regulators, or procurement teams.
At Genersol, we advise clients to seek UKAS-accredited certification, as it avoids future barriers to trade and provides assurance that your investment holds value.
Other Cost Considerations
- Implementation vs. Certification – The cost of preparing for ISO 9001 (developing procedures, training staff, internal audits) is separate from the certification audit fee. Many businesses underestimate this. Genersol provides tailored consultancy support to reduce wasted effort and align processes efficiently.
- Ongoing Audits – Certification is not a one-off exercise. You’ll need surveillance audits (usually annually) and full recertification every three years.
- Training & Culture – Investing in staff awareness and embedding ISO 9001 into your culture ensures sustainability and can reduce long-term costs by avoiding non-conformities.
Typical Cost Ranges
- Micro businesses (<10 staff): £3,000–£6,000 (implementation + certification over 3 years).
- SMEs (10–250 staff): £7,000–£20,000 depending on complexity and sites.
- Large organisations (250+ staff, multi-site, regulated industries): £25,000+ over 3 years.

- Ensure you achieve accreditation that adds long-term business value.
ISO 9001 is more than a badge. With the right approach, the investment pays for itself many times over.

I have been delivering projects for over forty years. I have been ‘teaching’ project management for over 25 years. I experienced a life changing project disaster in the 80s and vowed never to put myself in that situation again. I compiled my first list of reasons for project failure in the 90s when running PM programmes at Lancaster University. Over the years I have seen similar lists being proffered by a range of consultants, academics and practitioners who promote their way of dealing with them. The fact that similar lists keep on appearing suggests the remedies are not very successful!! It’s not altogether surprising as we are dealing with human beings. My latest list is a short one: • Fear • People tell lies • Dont care • Cant be bothered • Lack of trust • Collective (shared) incompetence • Not doing the basics Let’s translate this into something personal: • I am afraid • I tell lies • I don’t care • I cant be bothered • I don’t trust... • If I am part of a team they cant pin it on me • I didn’t do the basics We need to turn this on its head to find the solution. But even that is problematic because even if you do all the right things your project may not succeed - but you will have a much better chance. So driver for project success: • I am courageous • I tell the truth • I care • I am going to make this work • I must build trusting relationships • I will not hide behind team failure • I will do the basics The theory of project management is easy - it’s putting it into practice that is the difficult bit. I can explain the fundamental theory in a few hours. It takes a lot of practice to get it to work properly. Stick with me for how to maximise success.
