UK GDPR does not treat ChatGPT Business as a magic exemption — and it does not require you to ban useful AI either. It requires you to know what personal data flows through the tool, who is accountable, how long information is kept, and how you demonstrate supervision when something goes wrong. Consumer ChatGPT accounts make those questions painful to answer. A governed business workspace gives compliance and IT a documented starting point.
Controller, processor, and workplace data
When employees paste customer details, HR notes, or supplier contracts into personal AI accounts, your organisation may still be accountable for that processing — even if the vendor terms differ from your own policies. ChatGPT Business moves work into an organisation-owned environment with member management and business data handling terms. Your Data Protection Impact Assessment should name approved tasks, prohibited data types, and who signs off outputs that touch clients or regulators.
Compliance teams often discover shadow AI during a routine audit: a conversation thread contains identifiers nobody approved for external processing. The failure mode is not always malice — it is convenience without architecture. Personal logins sit outside joiners-movers-leavers processes, weaken retention arguments, and scatter evidence across individual billing boundaries.

Lawful basis and proportionality
Most internal drafting, research summaries, and procedure updates can proceed under legitimate interests or contract performance — provided you document the balancing test and apply minimisation. Customer-facing or special-category data needs tighter criteria. Start with lower-risk internal workflows, measure review quality for four weeks, then expand with written criteria rather than optimism.
