Accountants can use AI tools safely with client data, as long as you use business-grade tools rather than free public ones, keep confidential information out of consumer chatbots, control who can access what, and always check the output before you rely on it. Used this way, AI speeds up routine work. Used carelessly, it risks exposing client data and producing confident but wrong answers.
AI is becoming part of everyday practice, from drafting to summarising and analysis. The trick is to capture the time savings without creating a data-protection or accuracy problem. Here is how.
The main risk: free public AI tools
The biggest danger isn’t AI itself, it’s staff pasting client financials or personal data into free, public AI websites where you have little control over how that data is handled. Your first move is a clear policy on what can and can’t go into which tools, and training so everyone understands it.
For most firms of your size, this sits within fully managed IT at about £45 to £100 per user per month, billed per user, with support, security and backups included.
Why business-grade tools are safer
Tools like Microsoft 365 Copilot work within your existing Microsoft environment and its protections. They respect the access permissions you already have, so a user only sees information they’re allowed to, and they don’t use your business data to train public models. That’s a very different proposition from a free chatbot.
Get the foundations right
- Tidy up access permissions so people can’t surface client data they shouldn’t see
- Enforce multi-factor authentication and least privilege
- Set a clear AI usage policy and train staff on it
- Keep a qualified person checking every AI output, because accuracy and professional judgement still rest with you
Don’t forget your duties
Under UK GDPR you remain responsible for the personal data you process, and your professional standards still apply to advice based on AI output. Good tooling and clear rules let you use AI while meeting both.
A real example: a well-run environment
Firms with a well-organised Microsoft 365 environment are best placed to adopt AI safely. We were closely involved in developing the business systems that helped a client grow from 20 users to 100 over five years. A tidy, well-secured environment is exactly what makes new tools safe to add.
