Summary
On 22 October 2026 the London Borough of Hillingdon approved details (49261/APP/2026/2094) pursuant to Condition 25 (Air Quality Assessment) of planning permission 49261/APP/2024/2904, dated 12 March 2026, for the demolition of the existing building at Unit 4, Silverdale Industrial Estate, Silverdale Road, Hayes and the construction of a data centre building (Class B8) with roof-level plant, one emergency generator and flue, sprinkler tank and pumphouse, security guard house, a kiosk substation and MV building, access road, parking and landscaping. The council's dated approval shows the data-centre permission is an issued, live consent: it is the sixth condition approval on it since May 2026, after the construction management, low emission strategy, contaminated land, flood risk, materials and landscape details. Permitted status is supported as of 22 October 2026. No demolition, construction or operation is established; the condition approved here must precede installation of the generator, but no works are inferred from it. evidence

- Derivation
- coordinate_transform
- Precision scope
- Area centroid of the 0.47 ha application-site polygon that the Greater London Authority's London Planning Datahub holds for Hillingdon planning permission 49261/APP/2024/2904, computed in British National Grid (510282.35, 179478.28) and converted to WGS84 with pyproj 3.7.1. It lies inside the boundary, 25.8 m from the nearest edge; it is not a building footprint or surveyed position.
- Horizontal uncertainty
Not reported
The Datahub publishes no positional accuracy for the application boundary; the point is the centroid of a 0.47 ha site whose new building and generator compound lie within a few tens of metres of it.

A locator places the site on the map. It is not a building footprint, a construction extent or a surveyed boundary unless the use scope is an official boundary, and even then it is a parcel or permit boundary.
