Why prices sit where they do

Electricity is what sets the United Kingdom apart on cost. Commercial power at $0.442/kWh is more than four times Virginia's $0.103 and well above Germany's $0.283, so the energy component rather than the space component drives the total for a British deployment. Supply is also concentrated: of the 17 facilities in the catalog, 12 are in London and the rest sit in Slough, Cardiff, Corsham and Farnborough, for 282 MW recorded in total, of which only two sites are in the pipeline, and just two are flagged AI-ready. Network-facing tenants stay in London for the interconnection regardless of the tariff, but nothing else has to. The practical test is whether a workload genuinely needs London: if it does not, the same requirement placed 11 ms away in the Netherlands sits against a $0.22/kWh tariff, roughly half the British rate, and at this level of consumption that gap compounds every month of the term.

Frequently asked questions

How much does colocation cost in United Kingdom?

No published wholesale $/kW benchmark exists for United Kingdom yet, so we show nothing rather than an estimate. What is verifiable: the catalog tracks 109 facilities here. Run at least three quotes in parallel — where no benchmark is published, individual offers vary far more.

Why is colocation priced the way it is in United Kingdom?

Commercial electricity in United Kingdom is $0.454 per kWh, and power is the largest single input into a colocation rate. On top of that sit land and grid-connection availability, interconnection density, and how much capacity competes for the same tenants — 109 facilities in our catalog, 11 of them announced or under construction.

Where is colocation cheaper near United Kingdom?

On power alone, Netherlands ($0.179/kWh), Ireland ($0.210/kWh), Germany ($0.269/kWh) run below United Kingdom. Whether that becomes a cheaper contract depends on how much interconnection the workload needs — the comparison table shows what latency the move would cost.
