The UK Treasury published a Data Centre Covenant on 28 October 2026, as part of Budget 2026. It sets out tests that data centres are encouraged to meet and that “strategic data centres must meet to qualify for additional government action”, according to the policy paper on GOV.UK. In return, the document says, the government will use new powers in the Planning and Infrastructure Act to reserve and reallocate grid connection capacity for strategically important projects, including data centres. The same Budget includes what the Treasury called “the government’s most ambitious AI package yet”, worth £700 million.
In plain words: Britain is offering data-centre developers a faster route to grid electricity in exchange for local investment, efficiency and security commitments. The document says the government estimates the UK “will require 6 GW of AI data centre capacity by 2030”.

Business Pill · Grid Cost Allocation
An evergreen Business Engineer explainer on grid cost allocation: who pays when a new connection or line is built. It explains the general idea only and does not discuss the covenant.
The key insight: As we read it, the covenant turns grid access into the bargaining chip: HM Treasury says strategic data centres must meet five tests to qualify for reserved or reallocated grid connections and faster planning.
The covenant lists five tests. All data centres are encouraged to meet them; strategic data centres must meet them to qualify for the government’s support, the document says.
Lower electricity bills. Data centres should pay for their fair share of energy, “covering any energy costs they create”, and make “credible commitments for the grid capacity they request”.
Invest in local communities. Strategic data centres should agree a Local Benefit Plan “that commits to substantial investment, developed with the local community and linked to the development’s size”, on top of existing Section 106 and Community Infrastructure Levy obligations.
Environmental standards. New facilities should be designed for a Power Usage Effectiveness of 1.3 or better, minimise demand for public water supplies, capture waste heat where there is a viable local user, and, for strategic sites, report annually on energy and water use.
Jobs and supply chains. Developers should create local jobs and apprenticeships, prioritise UK suppliers, and the most strategically important sites will be expected to make “a meaningful contribution to the development and deployment of British AI hardware in the UK”.
Security. Data centres should provide secure UK access to compute for the NHS and other public services and work with the National Cyber Security Centre on resilience beyond baseline requirements.

What the Government Offers in Return
The document says the government will establish a new Ministerial Control Centre, chaired by the Minister for AI, that “will use the power of the state to accelerate time to power and speed up the planning process for the most strategic data centres”. For sites that demonstrate sufficient strategic value, it lists four actions:
Reserve and reallocate connections. Use Planning and Infrastructure Act powers to reserve future grid capacity and reallocate capacity released when other projects leave the connections queue.
Identify additional capacity. Work with NESO and the network companies to find locations where capacity may be available before 2030.
Transfer pre-2030 contracts. Where needed, facilitate the transfer of pre-2030 data-centre connection contracts to strategically important data centres.
Temporary on-site power. A “tightly controlled framework” to permit on-site generation until a grid connection is secured, only for exceptionally strategic projects.
The government will set out the definition of strategic data centres and the additional criteria “in due course”, the document says.
What the £700 Million AI Package Funds
Where the UK’s AI security money goes, ยฃ millions: National AI Biosecurity Initiative 165 (ยฃ100M lab + ยฃ50.5M bio-surveillance + ยฃ14.5M countermeasures, our arithmetic), cyber defences 154, AI Security Institute 120, National Agentic Security Unit 40. The lines total ยฃ479M (our arithmetic); the Treasury says around ยฃ500 million. Source: HM Treasury, Budget 2026 document, GOV.UK, 28 Oct 2026.
The Budget 2026 document says the government has invested “over £700 million” in AI at this Budget, and that it “will therefore invest around £500 million to build the secure foundations for an AI-enabled economy”. Bloomberg, in a post on X, described it as an extra £500 million for AI safety and security. The document itemises these security lines:
AI Security Institute. An additional £120 million.
Cyber defences, £154 million. A new £70 million National Exposure and Real-Time Vulnerability (NERV) Centre at the National Cyber Security Centre, an additional £24 million for the public sector AI defence programme, and £60 million for the first phase of a national Cyber Shield, including a £25 million AI and Cyber Security Challenge Fund.
National Agentic Security Unit. £40 million to “detect, investigate and respond to cases of rogue agentic systems”.
National AI Biosecurity Initiative. £100 million to establish an AI Biosecurity Lab, which the document says “will be supported by up to £200 million in AI model credits from OpenAI and Anthropic”, plus partnerships with Google DeepMind and Basecamp Research; £50.5 million for bio-surveillance; and £14.5 million for medical countermeasures. By our arithmetic, that is £165 million.
By our arithmetic, the four security lines total £479 million, against the document’s “around £500 million”.
Beyond security, the document lists an additional £140 million for the Sovereign AI Unit, £30 million to pilot local AI partnerships with three Yorkshire authorities, a £60 million AI Pathfinder Fund, an additional £60 million for the Sovereign AI Fund from 2027-28 with a new focus on physical AI, an additional £23 million for the AI Economics Institute and a further £20 million for AI hardware, including a UK advanced Chip Design Academy led by the University of Edinburgh. It also says the Ministry of Defence “is assessing opportunities to increase the UK’s sovereign compute and data centre capacity through its secure estate”.
Wider Grid and Planning Reforms
Beyond the strategic tier, the covenant lists reforms for all viable projects. They include support for Ofgem’s data-centre commitment fee and queue management measures “to deter speculative demand”, more choice for developers to self-build connection infrastructure, and a draft Data Centre National Policy Statement for consultation. The government will also continue to deliver the five AI Growth Zones across England, Scotland and Wales, the document says.
Connecting the Coverage
Our SAIL taskforce piece reported on 22 October that a group whose members include Nvidia, Microsoft and Cisco told UK ministers Britain had “roughly 12 months” to win public consent for data centres, and asked for a “compact” showing communities what they gain. What’s new: the government has now published a covenant with a Local Benefit Plan requirement for strategic sites.
Our Thailand data-centre rules piece noted on 27 October that the Financial Times had reported the UK was considering forcing data centres to invest locally to meet a new AI “covenant”. What’s new: the Budget text, with the five tests and the grid powers.
Our earlier pieces covered local conditions elsewhere. Our Oklahoma City piece covered a zoning approval with a 55 dB noise limit and a water cap, and our NextDC piece covered NEXTDC removing approximately A$140 million of net revenue and Underlying EBITDA from its fiscal 2027 guidance after power works for a Melbourne site were suspended amid community opposition.
The Structural Read
As we read it, the exchange is explicit in the document: local investment, efficiency, jobs and security commitments on one side, and on the other a Ministerial Control Centre that the document says will use the power of the state to accelerate time to power.
The Treasury puts the scale of the need in the document itself, saying the government estimates the UK will require 6 GW of AI data centre capacity by 2030.
As we read it, the key terms are still open: the document says the definition of strategic data centres and the additional criteria will be set out in due course.
HM Treasury, Data Centre Covenant, 28 Oct 2026
“This Covenant sets out a clear offer: government will support faster and more certain delivery of the data centres the country needs in return for responsible development that delivers lasting benefits for communities.”
Three Implications
FOR DATA-CENTRE DEVELOPERS Strategic sites will need a Local Benefit Plan linked to the development’s size and a design target of a Power Usage Effectiveness of 1.3 or better, the covenant says.
FOR PROJECTS IN THE GRID QUEUE The document says the government will use Planning and Infrastructure Act powers to reserve future capacity and reallocate capacity released when other projects leave the queue.
FOR UK AI COMPANIES The Budget release lists an additional £140 million for the Sovereign AI Unit to help UK AI companies scale.
The framework argues: “It describes the intersection of three powerful forces: geopolitics, cultural transformation, and economic change.”
The covenant ties those forces to one input, grid power, framing domestic data-centre capacity as a matter of national resilience. The framework was published in June 2026 and does not discuss the covenant.
What Is Not Established
The covenant does not define a strategic data centre, a megawatt threshold or the size of a Local Benefit Plan; the government says it will set those out later. It does not say how much grid capacity could be reserved or reallocated, or which projects would qualify. The Budget document does not reconcile its itemised AI lines with the “over £700 million” total, and does not say whether the additional £60 million for the Sovereign AI Fund is part of the £140 million Sovereign AI Unit line. We read the GOV.UK documents; we did not read the Reuters, Bloomberg or Financial Times articles in full, and we did not contact HM Treasury.
This Week In The AI Supercycle
Execution Fault Lines, Concentrated Demand, and Geopolitical Firewalls
This week’s issue: the AI build is not short of demand for its parts. It is short of cheap money, and its end revenue rests on a narrow base of large, often venture-funded buyers.
Budget 2026 pairs a £700 million AI package with a Data Centre Covenant: strategic data centres that meet five tests on energy costs, local investment, efficiency, jobs and security can qualify for reserved or reallocated grid connections and faster planning, according to HM Treasury’s documents of 28 October 2026. The document says the government estimates the UK will need 6 GW of AI data centre capacity by 2030.
A note on sourcing. The covenant’s tests, the government’s grid and planning commitments and the 6 GW estimate are from HM Treasury’s policy paper, Data Centre Covenant, published on GOV.UK on 28 October 2026. The AI package and its itemised lines are from the Treasury’s Budget 2026 document and press release the same day; Bloomberg’s description is from its post on X. The £165 million and £479 million figures are our own arithmetic. Earlier items restate our previous pieces, each with its own source. We did not contact HM Treasury.
