UK Budget sets a Data Centre Covenant: faster grid and planning for strategic sites that meet five tests

See how this story connects

HM Treasury published the Data Centre Covenant with the 28 October 2026 Budget. It sets five tests that all data centres are encouraged to meet and strategic data centres must meet to get extra government help: pay their share of energy costs, agree a Local Benefit Plan with substantial investment in the host community, meet environmental standards (a Power Usage Effectiveness of 1.3 or better for new sites, annual energy and water reports, waste heat reuse where practical), create local jobs and apprenticeships and support British AI hardware, and work with the National Cyber Security Centre on resilience. In return a Ministerial Control Centre chaired by the Minister for AI will speed up grid connections and planning for qualifying sites, using Planning and Infrastructure Act powers to reserve and reallocate connection capacity, and in exceptional cases allow on-site power until a grid connection is ready. The government estimates the UK needs 6 GW of AI data centre capacity by 2030.

Why it matters

Developers seeking priority grid access in the UK will have to sign up to community investment, efficiency reporting and security commitments; the government says it will define which projects count as strategic later.
