UK guidance says a limited part of the EU AI Act applies in Northern Ireland from 10 November
The Department for Business, Innovation, Science and Trade published guidance on 4 November 2026 on a specific and limited application of the EU AI Act in Northern Ireland under the Windsor Framework. The publication page says that application runs from 10 November 2026. The guidance PDF, also dated 4 November 2026, says the Act does not apply in Northern Ireland in full. It says it applies where an AI system is closely integrated with a tangible physical product placed on the Northern Ireland market. It says standalone or downloadable AI software, including AI used through a browser, an app or an API, is generally out of scope unless that software is closely integrated with a physical product. It says direct obligations for providers of general-purpose AI models do not apply in Northern Ireland. It says prohibitions on the use of AI do not apply there. The Joint Committee decision itself was not opened.

The Department for Business, Innovation, Science and Trade published guidance on 4 November 2026 on a specific and limited application of the EU AI Act in Northern Ireland under the Windsor Framework. The publication page says that application runs from 10 November 2026. The guidance PDF, also dated 4 November 2026, says the Act does not apply in Northern Ireland in full. It says it applies where an AI system is closely integrated with a tangible physical product placed on the Northern Ireland market. It says standalone or downloadable AI software, including AI used through a browser, an app or an API, is generally out of scope unless that software is closely integrated with a physical product. It says direct obligations for providers of general-purpose AI models do not apply in Northern Ireland. It says prohibitions on the use of AI do not apply there.

The PDF's timeline table gives these dates for in-scope products. Article 4, on AI literacy, applies from 10 November 2026. Article 5, on prohibited practices, applies from 10 November 2026, and the prohibitions on generating non-consensual intimate imagery and child sexual abuse material apply from 2 December 2026. Article 50(1), on disclosing an AI interaction, applies from 10 November 2026. Article 50(2), on marking AI-generated content, applies from 2 December 2026. Annex III high-risk use cases apply from 2 December 2027. Annex I high-risk regulated products apply from 2 August 2028. The PDF says Articles 50(3) and 50(4) do not apply in Northern Ireland.
What it means for business: a firm that only uses a chatbot, an app or an API in Northern Ireland is generally outside this guidance. A firm that places a physical product on the Northern Ireland market with a closely integrated AI system may have literacy, prohibition and interaction-disclosure duties from 10 November 2026, with later dates for marking and for high-risk duties. This describes the guidance. It is not advice on a particular product.
