How much does GDPR compliance cost for a small business?
Last updated 27 October 2026. General information only, not legal advice.
GDPR compliance has no standard price for a small business. The cost depends on the volume and sensitivity of the personal data you handle, the number of suppliers involved and how much documentation you already have. Costs fall into staff time, outside support and tools, and some of the work is ongoing rather than one-off.
What drives the cost of GDPR compliance?
The GDPR applies to any business processing personal data, however small. What changes the workload is the profile of the business:
- Type of data. Health, biometric and other special-category data bring extra conditions under Article 9, and more work.
- Volume and variety. Customers, employees, website visitors and CCTV footage each need to be covered.
- Suppliers. Payroll, IT, cloud and marketing providers that handle data for you usually need written contracts under Article 28.
- Risky processing. Some activities require a data protection impact assessment, and some businesses must appoint a Data Protection Officer under Article 37.
- Starting point. A business with no records or policies has more to build than one that only needs a refresh.
The three cost buckets
Internal time. For many small firms this is the largest cost. Someone must map the data you hold, decide a legal basis for each use, set retention periods and keep records. The Data Protection Commission’s guidance for SMEs expects you to tell people how you use their data, secure it, and be able to handle access requests within one month.
Outside support. This may be an audit, a DPIA, contract reviews or an outsourced DPO. Our GDPR audit and gap analysis is one way to scope the work first, so you know what is missing before committing to a full project.
Tools and training. Secure storage, access controls, a breach log and staff awareness all carry some cost. Our guide to the 72-hour data breach response shows what a basic incident process involves.
How can a small business keep costs down?
Start with a gap analysis against a checklist, fix the highest-risk gaps first, and reuse templates where they fit. Our GDPR guide for small businesses sets out the core obligations. Be wary of paying for tools or certificates before you know what you actually need.
For scale, a 2019 Mazars and McCann FitzGerald survey of Irish organisations found 58% put their GDPR spend to date at between €50,000 and €250,000. The respondents were not broken down by size, and the survey is dated, so treat it as an indication that costs can be significant for larger organisations rather than a benchmark for a small firm.

FAQ
How much does GDPR compliance cost for a small business in Ireland?
There is no fixed figure. Cost depends on how much personal data you handle, what kind it is, how many suppliers process it for you and what already exists. Many small businesses can break the work into a one-off set-up phase and a lighter ongoing review.
Is GDPR compliance a one-off cost?
No. Set-up work such as records, policies and contracts is largely one-off, but you must keep them current as your systems, suppliers and processing change. Training, breach readiness and requests from individuals recur.
Can a small business do GDPR compliance itself?
Yes. GDPR does not require an outside adviser. The Data Protection Commission publishes guidance for small and medium-sized businesses, and the EDPB has a data protection guide for small businesses. Some firms prefer outside support for specific tasks such as an audit or a DPIA.
