Manor Farm Data Centre Site, Poyle Road, Slough

Announced

United Kingdom · 1 project · Last reported

Summary

Tritax Big Box's half-year report, published on 5 August 2026, identifies its Manor Farm data-centre scheme on the 74-acre site at Heathrow in the Slough Availability Zone: 107 MW of power to be delivered in 2027 (a further 40 MW in 2029), a 107 MW Phase 1 pre-let in solicitors' hands, site preparation expected to begin in the second half of 2026 and practical completion expected in Q2 2028. This dated company disclosure supports announced status as of 5 August 2026. Planning permission exists: the Secretary of State allowed appeal APP/J0350/W/25/3366043 and granted permission for application P/10076/013 on 10 June 2026, and Tritax reported on 27 July that the six-week challenge period ended without challenge. Both dates fall outside the 85-day window, so the consent is recorded as context and permitted status is not asserted. No site preparation, construction or occupier is established; the 2027 power, H2 2026 site preparation and Q2 2028 completion dates are forecasts. evidence

Precision scope
Applicant-declared site point (easting 502958, northing 176233) on the planning application form for P/10076/013, published by Slough Borough Council as inquiry core document CD 1.1, converted to WGS84 with pyproj 3.7.1 (EPSG:27700 to EPSG:4326). It falls inside Area A, the northern parcel of the 8.16 ha appeal site that holds the consented data-centre building. It is not a building footprint, the red-line boundary or a surveyed position.
Horizontal uncertainty
Not reported

The application form publishes no positional accuracy, and the data-centre building's position relative to the point is shown only on plans without coordinates; the 8.16 ha application site extends a few hundred metres around it.

Geometry evidence

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.
