Market context
The Reading data centre market
Reading, with neighbouring Bracknell and the wider Thames Valley, forms the largest cluster of digital businesses outside London and a natural extension of the M4 data centre corridor. As power tightens in Slough and West London, operators look further west along the M4 to Berkshire towns where land and connections can be easier to secure. The area's concentration of technology and financial-services employers, deep fibre and proximity to London sustain colocation and enterprise demand. Connectivity, the Thames Valley tech base and spillover from the constrained Slough cluster shape the market, with grid timing the main constraint on larger new sites.

What limits new data centre capacity in Reading
Grid connection timing, transmission headroom and cooling-water access are usually the real constraints on new Reading capacity, not land.
Reading sits on the same broadly constrained southern network as Slough and West London, so firm large-load connection dates are the hard part of any new project. The town's role is partly as relief for the saturated Slough core, with operators securing powered sites further along the M4 where headroom and timelines are more workable. Water and connection certainty increasingly decide which Thames Valley schemes proceed.
