Frequently Asked Questions
What are the main costs involved in ISO certification?
ISO certification involves several distinct cost categories: the registrar's audit fees (Stage 1, Stage 2, and ongoing surveillance audits), consultant fees if you use external support for implementation, the cost of purchasing the official standard document, any software purchased to manage the system, and the internal staff time invested in building and maintaining it. Staff time is often the largest cost that businesses underestimate.
How much does ISO 9001 certification typically cost for a small business?
For a small business with fewer than 20 employees, total costs typically range from £3,000 to £8,000 for the initial certification, depending on whether you use a consultant and which registrar you choose. Annual surveillance audit fees then typically range from £800 to £2,000. These are broad estimates; actual costs depend significantly on your industry, processes, and chosen registrar.
Can I reduce the cost of ISO certification by doing it without a consultant?
Yes, though the trade-off is a larger investment of internal time and a higher risk of audit failures at the first attempt. Self-implementation works well for businesses where a team member has prior ISO experience or where the processes are relatively straightforward. Many businesses take a middle path, using a consultant for the gap analysis and key documentation, then managing implementation internally.
Are ISO certification costs tax deductible?
In most cases yes, as ISO certification costs are incurred wholly for business purposes. However, tax treatment depends on your jurisdiction and specific circumstances. In the UK, these costs would generally be allowable as a business expense for Corporation Tax purposes. You should confirm the position with your accountant rather than relying on general guidance.
