Achieving ISO 27001 certification can seem daunting and potentially costly, especially for those new to information security management.
To make things more transparent, it's essential to understand the various ISO 27001 certification costs involved and how they break down across different stages of the certification journey.
This article breaks down the ISO 27001 certification costs into four key stages: gap analysis, pre-certification consultancy, certification costs, and ongoing auditing and maintenance. Additionally, we'll look at how these costs can vary depending on the size of your organisation.
1. Gap Analysis
The gap analysis is the first step in your ISO 27001 journey. It involves assessing your current information security processes against the requirements of the ISO 27001 standard.
The goal is to understand where your organisation stands and identify areas that need improvement.
Small Organisation (10-50 employees): £2,000 - £5,000
Medium Organisation (50-250 employees): £4,000 - £8,000
Large Organisation (250+ employees): £7,000 - £15,000
The cost variation typically depends on the complexity of your existing systems, the number of processes in place, and the level of detail needed during the review.
For more information on the gap analysis stage, see Network Assured's article on ISO 27001 costs.
2. Pre-Certification Consultancy to Set Up the ISMS
Once you understand your current state, the next step is to address any gaps by implementing an Information Security Management System (ISMS). This often requires external consultancy to help set up policies, procedures, and controls.
Small Organisation (10-50 employees): £3,000 - £10,000
Medium Organisation (50-250 employees): £8,000 - £20,000
Large Organisation (250+ employees): £15,000 - £50,000
Smaller organisations often rely on more templated solutions, whereas larger enterprises might require a bespoke approach to fit into existing, often complex, structures. The time required to build the ISMS increases significantly as the organisational size grows.

3. Certification Costs
This stage involves the actual certification audit performed by an accredited certification body. The certification is usually conducted in two stages: a preliminary review of your documentation followed by an on-site audit.
Small Organisation (10-50 employees): £4,000 - £6,000
Medium Organisation (50-250 employees): £6,000 - £12,000
Large Organisation (250+ employees): £10,000 - £25,000
These ISO 27001 certification costs vary based on the certification body's fees and the audit's required days. Larger organisations often require longer auditing periods due to the increased scope and number of departments involved.

4. Ongoing Auditing and Maintenance
ISO 27001 is not a one-time project; it requires ongoing commitment to maintain certification status. This includes internal audits, certification body surveillance audits, and ISMS updates as business needs evolve.
Small Organisation (10-50 employees): £1,000 - £3,000 per year
Medium Organisation (50-250 employees): £3,000 - £8,000 per year
Large Organisation (250+ employees): £7,000 - £15,000 per year
Ongoing ISO 27001 certification costs depend on your organisation's size and complexity. Larger organisations may need dedicated internal resources to ensure ongoing compliance, whereas smaller companies might outsource this responsibility.
How to Keep ISO 27001 Certification Costs Minimized
ISO 27001 certification can be a significant investment, but there are ways to effectively manage and minimise these costs. Here are some practical strategies to help reduce the overall expenditure:
Use Templates and Tools: Utilising available templates for policies, risk assessments, and procedures can save significant time and consultancy costs. Many high-quality, free, or low-cost templates are available online that can streamline the setup of your ISMS.
In-House Expertise: If possible, build internal expertise by training your staff. This reduces the need for external consultants. Investing in internal ISO 27001 training can also help to maintain compliance without relying heavily on third-party support.
Phased Implementation: Instead of achieving certification all at once, consider a phased approach. Implementing controls in stages allows you to spread the costs over time and also helps manage resources effectively without overwhelming the organisation.
Choose the Right Certification Body: Certification bodies may charge varying fees, so it's worth comparing several options to find the most cost-effective one. However, make sure they are accredited and reputable to avoid any issues down the line.
Perform a Thorough Gap Analysis: A detailed gap analysis can prevent unexpected costs later. Addressing gaps early will help avoid additional consultancy fees and the potential need for repeated audits.
Leverage Existing Systems and Processes: Where possible, integrate ISO 27001 requirements into existing processes instead of creating new ones. This can save both time and resources when setting up the ISMS.
Negotiate Fixed-Price Contracts: When working with consultants, negotiate fixed-price contracts instead of open-ended agreements. This ensures you clearly understand the costs involved without the risk of overruns.
Summary of ISO 27001 Certification Costs
Gap Analysis: £2,000 - £15,000 depending on size.
Pre-Certification Consultancy: £3,000 - £50,000 depending on size and complexity.
Certification Costs: £4,000 - £25,000 depending on the certification body and audit length.
Ongoing Maintenance: £1,000 - £15,000 per year depending on your internal resources.
Frequently Asked Questions (FAQs)
1. What is the average cost of ISO 27001 certification?
The average cost of ISO 27001 certification can vary widely depending on the size of the organisation and its existing security posture. For small organisations, the overall cost could range from £10,000 to £20,000, whereas larger enterprises may incur costs between £40,000 and £100,000 or more.
2. How long does it take to get ISO 27001 certified?
The time required to achieve ISO 27001 certification depends on the size of the organisation and its preparedness. Small to medium-sized companies typically take 3 to 6 months, while larger enterprises might take 9 to 12 months or longer.
3. Can we reduce costs by doing ISO 27001 in-house?
Yes, building in-house expertise and leveraging internal resources can help reduce costs significantly. However, this approach requires a dedicated team with the necessary skills and knowledge about the ISO 27001 standard.
4. Are there any hidden costs in ISO 27001 certification?
Some hidden costs could include internal staff time for implementation, training costs, and potential re-audit fees if the certification is not achieved in the initial attempt. Proper planning and conducting a gap analysis can help mitigate these unexpected expenses.
5. How often do we need to renew ISO 27001 certification?
ISO 27001 certification is valid for three years. During this period, surveillance audits are conducted annually to ensure continued compliance. After three years, a recertification audit is required to renew the certification.
6. What is the difference between initial certification and surveillance audits?
The initial certification audit is a comprehensive assessment to ensure your ISMS meets all ISO 27001 requirements. On the other hand, surveillance audits are conducted annually to verify that the ISMS is maintained and still compliant.
Conclusion
ISO 27001 certification is a significant investment, but it can greatly enhance your organisation's security posture and build trust with clients and partners.
ISO 27001 certification costs can vary widely depending on your company's size, current practices, and the level of external support required. Understanding the costs in each process stage can help you better plan your journey to certification and ensure there are no surprises along the way.
