A UK group sells a B2B platform to lenders and employers across the EU. Over three years, AI has crept into the product: a feature that scores credit applications for some customers, another that sorts job applications, a chatbot, and a document reader. Inside the business, teams use AI for fraud checks, customer service and marketing content, some of it for EU customers. Nobody holds a single list. Some features came from suppliers, some were built in-house, and some are a general-purpose model called through a cloud API.
The EU AI Act reaches UK firms in two ways. It applies to providers that place AI systems on the EU market, wherever they are based, and to providers and deployers outside the EU whose AI system's output is used in the EU. So the first question for each system isn't 'is it risky?' but 'are we the provider or the deployer, and does it reach the EU at all?'.
The dates have moved. The Digital Omnibus, Regulation (EU) 2026/1744, in force since 27 July 2026, put back the high-risk duties: Annex III uses such as credit scoring and recruitment from 2 December 2027, and AI in products covered by Annex I from 2 August 2028. Other parts already apply: the prohibitions since February 2025, general-purpose AI model duties since August 2025, and transparency duties since 2 August 2026. The extra time is useful only if the inventory, the classifications and the technical documentation start now.
The work is mostly reading: the Act and its annexes, the Commission's guidelines, and the group's own architecture records, model cards, contracts and supplier terms. AI can make that reading much faster. It can't decide what the law means for the business. This playbook describes how to organise the work. It is not legal advice, and neither is anything the assistant drafts.
