How Much Does EU AI Act Compliance Cost for UK Businesses?

External compliance support can range from targeted document work to a much broader legal or consultancy engagement. The useful comparison is therefore not a single supposed market price, but the scope of work, the business's role under the Act and the level of risk involved.

But enforcement is already phased in and progressing. And the cost of non-compliance, fines of up to €35 million or 7% of global turnover, plus reputational damage, is considerably higher than the cost of getting it right.

So what does EU AI Act compliance actually cost? And is there a way to do it properly without spending thousands on legal fees?

When a law firm quotes you for EU AI Act compliance work, the fee typically covers some combination of the following.

There is no single authoritative market price for this work. Costs depend on whether a business needs a narrow governance exercise, specialist legal advice, technical assurance, high-risk-system work or a wider implementation project.

• Initial scoping and risk assessment. A qualified solicitor or compliance consultant reviews your business, your AI tools, and your use cases to determine what obligations apply. This alone can cost £500–£1,500 depending on complexity.
• Document drafting. An AI Acceptable Use Policy, AI Literacy Policy, applicable Article 50 disclosures, Human Oversight SOP and Vendor AI Risk Register may all be useful depending on scope. The important comparison is what is included, how it is tailored and whether specialist legal advice is actually required for the issue.
• High-risk documentation. If your AI use falls into a high-risk category: recruitment, credit scoring, essential services: you also need a documented risk register, human oversight procedures, and, only if you're a public body, a public-service provider, or using AI for credit or insurance scoring, a Fundamental Rights Impact Assessment. These become legally required from 2 December 2027 and are more complex documents that require deeper regulatory knowledge.
• Review and sign-off. A qualified professional reviewing the documents for accuracy, consistency, and legal sufficiency before they are signed.

There are broadly three approaches to EU AI Act compliance for UK small businesses.

1. Option 1, do nothing. Free, but not recommended. Enforcement is already phased in and progressing. Fines are substantial. Even setting aside regulatory risk, having no documentation in place exposes you to reputational and contractual risk with clients who are themselves becoming more AI-governance conscious.
2. Option 2: DIY using templates. This can be low cost, but generic material still needs to be checked against your business, sector, AI tools and actual use cases. A template can be a useful starting point, but the strength of the resulting evidence depends on whether it reflects the controls and decisions your organisation has actually implemented.
3. Option 3: Use a specialist compliance tool. This is the middle ground that most UK SMEs will find practical. AI powered compliance tools can generate tailored documentation based on your specific business details at a fraction of the cost of a law firm: while producing output that is materially better than a generic template.

Clausely generates EU AI Act governance document packs from the information you provide about your business, sector, AI tools, headcount, EU exposure and governance arrangements. The documents are supplied in editable Word format for review and adoption.

• Essentials Pack: £399. Includes AI Acceptable Use Policy and AI Literacy Policy. Suitable for businesses with no EU facing AI use that want baseline governance documentation in place.
• Professional Pack: £899. Includes all Essentials documents plus Article 50 Transparency Disclosures, Human Oversight SOP, AI Incident Response Procedure, and Vendor AI Risk Register. Suitable for most UK businesses with EU facing AI use.
• High-Risk Ready Pack: £2,499. Includes all Professional documents plus a Fundamental Rights Impact Assessment, AI Risk Management Plan, and Conformity Self-Assessment Checklist. Suitable for businesses using AI in recruitment, HR, credit, or other high-risk contexts.
• Worker Protection Pack: £699. Includes Sexual Harassment Risk Assessment, Anti-Harassment Policy, Third-Party Harassment Policy, Harassment Reporting Procedure, and Training Record Template. Suitable for all UK employers needing to comply with the Worker Protection Act 2024.

The High-Risk Ready Pack brings the nine included governance documents into one fixed price package at £2,499. External legal or consultancy support may still be appropriate where a business needs advice on a complex classification, contractual or contentious issue.

The documents are not legal advice and are not a substitute for a solicitor where complex or contentious legal questions arise. Clausely is designed to reduce the work involved in creating and organising governance documentation, while leaving legal advice and implementation decisions with the business and its advisers where needed.

For context, consider what non-compliance could cost.

Article 99 contains different penalty tiers for different infringements. For undertakings, turnover-based calculations and the SME rule in Article 99(6) affect the applicable maximum, while the actual penalty must take account of the circumstances set out in the Regulation. Headline maximums should therefore not be treated as an automatic fine.

A breach of the prohibited AI practices provisions, such as deploying an AI system that manipulates people or exploits vulnerabilities, can attract fines of up to €35 million or 7% of global turnover.

Even a single data subject complaint to a national supervisory authority that triggers an investigation can result in significant legal costs, management time, and reputational damage, regardless of the outcome.

Against that backdrop, £399 to £2,499 for tailored compliance documentation is not an overhead. It is risk management.
