Summary
- Five applications were recorded across North Lanarkshire, Northumberland, North Tyneside, Enfield, and Brent.
- The largest is a 45,167 sq m reserved-matters filing covering two data-centre buildings at Cambois.
- Several filings advance existing developments rather than representing five entirely new data-centre projects.
Five data-centre planning applications have entered the latest UK development pipeline, with filings recorded across North Lanarkshire, Northumberland, North Tyneside, Enfield, and Brent.
The latest weekly update from AI Data Centre records 286 applications across 84 UK local planning authorities, with 101 awaiting decisions.
The most substantial filing in the latest set is a reserved-matters application at the former power station site at Cambois in Northumberland.
The application covers 45,167 sq m of gross internal area across two data-centre buildings on a 23.7-hectare site. The listed scheme includes buildings up to 31.1 metres high, 55 diesel generators, and air-cooled chillers.
The application concerns appearance, landscaping, layout, and scale under an existing outline permission rather than establishing an entirely new campus.
That distinction is important because the headline count of five new applications does not equate to five newly disclosed data-centre projects.
North Tyneside’s entry is a consultation connected to the Northumberland reserved-matters application at Cambois rather than a separate facility.
An Enfield-area filing covers reserved matters for site-wide advanced infrastructure and enabling works at land east of South Mimms Services. It includes permanent vehicular access that would also support temporary construction access.
In Brent, the entry is a condition-discharge application covering a construction logistics plan for an already permitted extension to an existing data centre in Neasden.
The North Lanarkshire filing concerns the proposed green data-centre development at Chapelhall, a project already present in the broader planning pipeline.
The pattern illustrates why raw application counts can overstate the number of distinct UK data-centre developments.
A large campus may generate multiple planning records as it moves through outline permission, reserved matters, enabling works, access, conditions, substations, amendments, and later construction phases.
Those follow-on applications are still useful indicators of buildability because they show whether a project is moving from a broad development concept towards specific buildings and supporting infrastructure.
Reserved-matters filings can reveal information that was not fixed at outline stage, including building dimensions, cooling equipment, generator numbers, landscaping, roads, and other site infrastructure.
Condition discharges and enabling-work applications can provide evidence that a developer is preparing to move from consent into construction.
The wider dataset tracked 2,682MW of declared capacity as of 8 September, although many applications do not contain directly comparable electrical figures.
Geographically, activity continues both in established data-centre markets and in newer clusters. North Lanarkshire had 13 tracked applications in the dataset, while Northumberland had nine, all of which were awaiting decisions.
Former industrial and power-generation locations can attract large developments because they may offer sizeable land parcels and existing electricity infrastructure. That does not remove planning constraints around generators, cooling equipment, building massing, noise, traffic, landscape, ecology, and construction logistics.
The latest five filings therefore represent movement through the development pipeline rather than a sudden addition of five independent campuses.
That distinction is important when assessing future capacity. Planning volume can show how busy the development market is, but the number of individual applications is not the same as the number of facilities likely to be built.
