TL;DR

The Regulation of Artificial Intelligence Act 2026 is now law in Ireland, an AI Office has been established in Dublin and its first chief executive appointed. Northern Ireland may end up the only UK region in which EU AI Act provisions bite directly, through the Windsor Framework — but no formal decision has been taken. Roughly 7,500 Northern Irish businesses trade across that border.

The regulator is live, the boundary is not

Dublin now has a functioning AI supervisor. Its reach is defined by output, not address: a business anywhere whose AI system produces results used inside the EU can fall within scope.

Stormont’s democratic scrutiny committee heard evidence on 6 August. Technical discussions between London and Brussels are complete. A formal decision has not followed. Until it does, firms in Belfast cannot say with certainty which regime governs the software they already run.

The scale is not marginal. Cross-border trade from Northern Ireland runs to about £10.5bn in goods and services, and roughly nine in ten of the businesses doing it are SMEs or micro businesses — the cohort least able to buy standing legal advice on a question two governments have not settled.

Procurement moves before legislation

The near-term pressure is commercial rather than statutory, argues Geoff McGimpsey of Foundry Marketing Partners, writing in the Belfast Telegraph. Irish public bodies buying systems that involve AI will ask suppliers whether risk has been assessed. A firm that cannot answer loses the contract regardless of what the Joint Committee eventually decides.

He notes that one Belfast law firm has warned that merely buying an AI system, rather than building one, can trigger obligations for an exporting business.

Looking forward

The UK side of this is harder to read than the Irish side. Domestic AI oversight remains distributed across departments and regulators, made messier still by DSIT’s abolition, though the Cabinet-level brief now held by Kanishka Narayan may pull it together.

For UK businesses generally, the practical lesson travels beyond Northern Ireland: anyone selling into the EU inherits AI Act expectations through procurement long before any domestic rule requires it. Knowing which AI tools sit inside your own operations — including the ones embedded in HR software and chatbots nobody procured deliberately — is the unavoidable first step.
