UK Prime Minister rejects data centre moratorium
The UK Prime Minister, Rishi Sunak, has rejected a proposal from Labour MP Ian Lavery for a moratorium on new data centres1, signalling the government's commitment to digital infrastructure growth despite rising concerns over energy consumption and environmental impact. This decision comes amidst a growing political debate surrounding the rapid expansion of data centres, which are vital for the UK's digital economy but also significant energy users. The discussion highlights a tension between fostering technological advancement and achieving sustainability goals.

Understanding the UK data centre moratorium debate
The debate around a data centre moratorium in the UK reflects a broader global conversation about the environmental footprint of digital infrastructure. As artificial intelligence (AI) and cloud computing continue to expand, the energy and resource demands of the facilities that power them are coming under increasing scrutiny.
What is a data centre moratorium?
A data centre moratorium is a proposed temporary halt or ban on the construction of new data centres. Proponents typically advocate for such a measure to allow time for regulatory frameworks to catch up with technological advancements, address environmental concerns, and ensure that infrastructure development aligns with national sustainability targets. The Green Party, for instance, has called for a moratorium on most new data centres across the UK, with an exemption for smaller, local-scale facilities.
The political landscape: calls for restriction
Calls for a moratorium have emerged from various political and environmental groups. Labour MP Ian Lavery reportedly raised concerns in Parliament about "vast" data centres proposed in his constituency, arguing that the land could be used for industries creating more local jobs and that communities face disruption. He suggested a moratorium until regulation improves and a critical national infrastructure levy is introduced to benefit local communities.
The Green Party has been particularly vocal, urging the government to "slam the brakes" on new data centres. Green Party leader Zack Polanski has demanded tighter planning rules, arguing that data centres should not be prioritised over communities, especially given potential water shortages. In Scotland, there have also been discussions around a data centre moratorium, particularly concerning the energy demands of AI. The Scottish National Party (SNP) National Council has supported a pause on new AI data centre applications to reconcile sector expansion with Scotland's energy and climate goals.
Why a moratorium was proposed: energy and environmental concerns
The primary drivers behind calls for a data centre moratorium are the substantial energy and environmental impacts associated with these facilities.
Data centre energy consumption and growth
Data centres are significant consumers of electricity, and their energy demand is projected to increase dramatically, largely due to the rise of AI. While the UK government estimated in early 2025 that data centres used around 2.5% of the UK's electricity, this figure is predicted to quadruple by 2030. Other research suggests that data centres already consume 5.9% of electricity in the UK. Modern AI-ready server racks can require 20-100+ kW of power, significantly more than traditional server racks, which typically use 5-15 kW. This escalating demand places considerable pressure on the National Grid.
Environmental impact and sustainability challenges
Beyond energy consumption, data centres pose several environmental challenges. They generate significant heat, requiring extensive cooling systems, which can consume large amounts of water. Some facilities rely on evaporative water cooling towers, drawing billions of litres annually. While the industry in England is more regulated, with many facilities using closed-loop systems that consume less water, the overall demand remains a concern, especially during periods of drought. The carbon emissions associated with powering data centres, particularly when relying on fossil fuels, also raise questions about their compatibility with net-zero commitments.
The government's stance and economic implications
Despite the environmental concerns, the UK government has firmly rejected calls for a moratorium, emphasising the economic benefits and strategic importance of data centres.
UK Prime Minister's rejection and rationale
Prime Minister Rishi Sunak stated he would not support a moratorium on data centres, acknowledging concerns but highlighting their potential as a "magnet" for investment. The government views data centres as critical infrastructure for nearly all economic activity and public services, having designated them as Critical National Infrastructure (CNI) in 2024. This designation places them on an equal footing with essential services like water and energy, reportedly making planning permission easier. The government argues that halting construction would send investment and jobs abroad, making Britain dependent on overseas computing for sensitive data. They also point to policies like AI growth zones, which allow local authorities to retain 100% of business rate growth to benefit communities.
Impact on digital infrastructure and economic growth
Data centres are the backbone of the UK's digital economy, supporting cloud computing, data storage, and the burgeoning AI sector. They contribute significantly to the economy, generating billions in gross value added annually and supporting tens of thousands of jobs nationwide. Further investment in digital infrastructure could deliver substantial economic impact by 2035. A moratorium could stifle this growth, hindering the UK's ambition to be a global leader in AI and digital services. The global and mobile nature of data centre investment means that if facilities are not built in the UK, they are likely to be built elsewhere.
Powering progress: an abundance-first approach to data centres
The debate around data centre moratoriums often frames energy as a scarce resource, leading to calls for restriction. However, an alternative perspective focuses on meeting the increasing demand through abundant, clean energy generation.
Meeting demand with clean, abundant energy
The energy demands of data centres, while significant, do not have to be an insurmountable problem necessitating a moratorium. Instead, they represent a challenge that can be met through innovative and scalable clean energy solutions. Fuse Energy aims to rebuild the energy system from scratch, deploying vast amounts of clean energy to meet growing demand.
