Market context
The Slough data centre market
Slough holds one of the densest concentrations of data centre capacity in Europe, anchored by the SEGRO-owned Slough Trading Estate and the wider western M4 corridor. Closeness to West London, deep fibre and an established operator cluster keep it a magnet for hyperscale demand, even as available power tightens. Colocation, hyperscale data centre campuses and AI workloads concentrate here, with connectivity into the London internet exchanges, and energy efficiency and power availability deciding which projects proceed. Internationally a data centre is written as a data center.

What limits new data centre capacity in Slough
Grid connection timing, transmission headroom and cooling-water access are usually the real constraints on new Slough capacity, not land.
The Slough and West London grid is heavily subscribed, so securing a firm, large-load connection on a near-term date is the hard part of any new project. Operators increasingly look further along the M4 and to other regions where connection timelines are shorter. A credible energisation date now matters more than the parcel itself.
