How to keep ChatGPT safer for business data (UK SMB GDPR guide)

Short answer: it depends far less on ChatGPT than on which account you use and what you paste into it.

A personal Free or Plus login used to draft a blog post is a very different risk from the same person pasting a spreadsheet of customer names, emails and order history into that same chat window. The tool is identical. The exposure is not.

This guide explains the difference in plain English, and gives you a short set of rules you can hand to your team this week. It is general guidance for UK and Irish small businesses, not legal advice - if you handle sensitive categories of data (health, children's data, criminal records) or operate in a regulated sector, take proper advice.

Who this is for

• Owners and directors of UK/IE businesses with 1–50 staff who already have people using ChatGPT, whether they approved it or not.
• Marketing, sales and email managers who want to use AI on real customer data without creating a problem.
• Office managers and operations leads who have been asked "are we allowed to use this?" and don't have an answer yet.
• Anyone who has quietly wondered whether the customer list they pasted in last month is now "out there".

If nobody in your business has used ChatGPT yet, this is still worth ten minutes - it is easier to set the rules before the habit forms than after.
