Whitehall to Decide Fate of Brick Lane Datacentre After Council Rejection

A 5,200 square metre datacentre proposed for the former Truman Brewery site on Brick Lane has landed on the desk of the UK government, after Tower Hamlets council threw out the plans and Housing Secretary Steve Reed called in the decision. Ministers now have until 17 August to determine whether the project goes ahead, a deadline that has intensified a fight already drawing in local residents, planners and grid analysts.

Unlike the sprawling AI training campuses now common in the US and increasingly proposed across Europe, this facility is not primarily destined for machine learning workloads. According to the proposal, the site would mainly serve high-frequency trading operations tied to London's financial district, placing it in a different category from the generative AI infrastructure boom driving most current datacentre controversy. Its peak output is rated at 5.2MW, roughly the electricity draw of 15,000 homes, a figure that has become central to the local objection campaign.

That power demand sits at the heart of a broader tension documented in a recent London Assembly report, which found that the capital's datacentre expansion is actively slowing housing delivery. The report points to a shared bottleneck: London's electricity grid does not have the spare capacity to support both large-scale datacentre buildouts and the new housing developments the city urgently needs. Every megawatt allocated to server halls is, in effect, a megawatt not available for new residential connections, a trade-off that planning authorities are increasingly forced to adjudicate directly.

Noise is the second major complaint driving opposition to the Brick Lane scheme. Campaigners point to an existing datacentre in the vicinity that has already generated a steady stream of resident complaints over a persistent low-level hum, a nuisance that critics argue would only compound if a second, similarly sized facility were built nearby. In a dense, mixed-use East London neighbourhood known for its markets, nightlife and residential terraces, the prospect of continuous mechanical noise from cooling systems has become a rallying point for local campaigners well beyond the immediate planning technicalities.

The call-in itself is significant. By pulling the decision away from Tower Hamlets and into central government hands, Reed has effectively nationalised what would otherwise have remained a local planning dispute. That move signals how seriously Whitehall is treating datacentre capacity as a matter of economic and digital infrastructure policy, not simply a neighbourhood zoning question. It also means the outcome could set a precedent for how future datacentre applications in dense urban areas are handled when local councils push back.

Whatever the government decides by 17 August, the case has already surfaced the central dilemma facing London and other major cities: finite grid capacity is now a genuine constraint on urban growth, and datacentres, whether serving AI models or financial trading engines, are competing directly with housing for the same limited resource.
