UK budget ties critical data center grid access to community pledges

UK Chancellor John Healey announced a British Data Center Covenant in his 2026 budget speech on Oct. 28, offering critical data centers priority grid connections in exchange for community and water commitments.

Critical data centers that comply will get priority grid connections and permission to build new on-site power generation while they wait, Healey said. Operators are required to invest in local communities, create jobs and protect water supplies.

For allocators underwriting UK compute, the covenant makes grid priority a compliance condition attached to a class of projects rather than a queue position. Commitments on local jobs, water use and community investment become development costs that must be defined and delivered, and they belong in the diligence file next to power and land.

Healey said the covenant would support data center development in Britain, which he cast as vital to the government's AI and national security goals. He said the government must “seize the opportunities and guard against the risks,” adding that the budget backs AI safety and security with “an extra half a billion pounds.” “Nowhere is the necessary role for the state clearer,” he said.

Data center capital follows the power calendar, as Private Infrastructure Daily previously reported. Gary Watson, managing director of UK operator Stellanor, called the covenant “the right deal.” “Grid capacity shapes every decision in our sector, and we can't keep building data centers and expect the grid and local communities to work around us,” he said. He added that operators should earn their place through local jobs and skills, responsible water use, renewable power and genuine engagement with neighbors.

Gary Wojtaszek, executive chairman and interim CEO of Pure Data Centres Group, welcomed the covenant, particularly its priority for critical projects that support communities. He said responsible developers are already investing in jobs, water supplies and local communities, and that Pure stands ready to help refine the requirements and understand how they will influence planning and grid connections.

The unresolved term is how the tests are written and who applies them. Watson's argument is the practical one for smaller sponsors: a regime calibrated to the largest campuses would leave in-city and regional projects outside the priority lane, and those are the sites closest to the public services the government says it wants to serve.
