Powering the AI economy: how the British Data Centre Covenant changes the rules – Autumn Budget 2026

 
The growth of artificial intelligence, cloud computing and digital services is driving unprecedented demand for data centre capacity.

Recognising that data centres are becoming as important to the modern economy as transport, energy and telecommunications infrastructure, the Autumn Budget introduced a new British Data Centre Covenant designed to align the expansion of the UK’s digital infrastructure with national economic, environmental and security objectives.

The government views AI as one of the most significant opportunities for economic growth and productivity improvement over the coming decade. However, delivering those benefits requires substantial investment in computing capacity, energy infrastructure and data storage. The Autumn Budget therefore sets out a framework under which strategic data centres will receive enhanced government support while accepting broader responsibilities to the communities and economy they serve.

Under the Covenant, data centres will be expected to satisfy five core principles.

• 1. They must contribute to lower electricity costs and greater energy resilience. Strategic data centres will be required to pay their fair share of energy system costs and support clean power and grid flexibility, ensuring that households and businesses do not bear additional costs arising from digital infrastructure expansion.
• 2. Data centres must invest in local communities. Operators will be expected to develop Local Benefit Plans and provide meaningful investment in local priorities such as transport improvements, public amenities, regeneration initiatives and community infrastructure. The government’s intention is that communities hosting nationally important infrastructure should directly share in the resulting economic benefits.
• 3. The Covenant places significant emphasis on environmental sustainability. Data centres will be expected to minimise water consumption, publish annual reporting on resource usage and adhere to high environmental standards. Where practical, data centres should also capture and reuse waste heat for nearby homes, schools, hospitals and businesses, improving overall energy efficiency.
• 4. Operators will be expected to create jobs, apprenticeships and support UK supply chains. Strategic projects should invest in workforce development, provide high-quality training opportunities and prioritise British technologies and suppliers. The government also expects data centres to contribute to the development of UK AI hardware capability and wider reindustrialisation objectives.
• 5. Data centres must contribute to national security and technological sovereignty. Facilities will be expected to provide secure and reliable computing infrastructure, work closely with national cybersecurity authorities and support the resilience of critical public services, including the NHS and wider government operations.

In return, the government will create a new Ministerial Control Centre to accelerate access to power connections and infrastructure approvals. The Budget also commits to using new powers to reserve and prioritise electricity capacity, identify available grid connections, facilitate connection transfers where necessary, and in exceptional circumstances provide temporary power solutions for strategically important projects.

The British Data Centre Covenant represents a significant shift in policy. Rather than treating data centres as purely private commercial developments, the government is establishing them as strategic national assets capable of supporting AI leadership, economic growth, national resilience and regional development. For investors, operators and local communities alike, the Covenant signals a new model where technological infrastructure must deliver benefits not only to shareholders, but also to society and the wider UK economy.
