London still dominates UK's datacenter landscape
Regional investments are rising while London remains the hub of the country's data infrastructure.
1London's datacenter dominance
Nearly 40% of UK datacenters are located in London, hosting two-thirds of the nation's colocation capacity. The capital has 219 active facilities providing 1.048 MW of computing power. Its strategic position serves financial markets and benefits from fiber-optic networks along the M4 corridor. With 15 planned expansion projects, London aims to maintain its leadership position in data infrastructure.
2The rise of Southeast England
Outside London, Southeast England has the highest concentration of datacenters with 62 active facilities and 128 MW capacity. Ten planned projects make it the second fastest-growing region. Major investments like Equinix's massive campus at South Mimms near the M25 orbital motorway are transforming the area into a significant datacenter hub.
3Northwest and other regions
Northwest England stands out with 39 active facilities and 52 MW capacity. Five upcoming projects demonstrate the region's growth potential. Eastern England and Scotland have 45 and 49 active datacenters respectively. Wales, with just 32 facilities, ranks second nationally with 154 MW capacity thanks to high-capacity sites.
4Developments in Southwest and Northeast
Southwest England has the fewest datacenters (20) with 54 MW capacity, but this may change with controversial projects like the 1.5 GW AI-optimized campus in Devon. In Northeast England, Blackstone plans a massive 720 MW facility near Blyth that could redefine the region's datacenter landscape.
5Energy costs and project delays
OpenAI's decision to pause its Stargate project in North Tyneside highlights how UK energy costs impact datacenter investments. Power constraints and planning challenges are pushing developers to look beyond London, accelerating regional datacenter growth across the country.
6Karas Plating's analysis
Specialist firm Karas Plating, which focuses on electrical components and power systems, mapped the UK's datacenter landscape. The company aims to identify new business opportunities under the government's AI Opportunities Action Plan. Their research identified 555 server farms with total capacity of 1.6 GW nationwide.
7Comparison with the US
The UK ranks second globally in facility count after the US, though there's a significant capacity gap between the two countries. Britain's datacenter infrastructure is expanding rapidly to meet growing demands from AI and financial sectors, positioning itself as a key European hub.
8The importance of regional growth
London's power constraints and planning difficulties are redirecting investments to other regions. High-capacity regional infrastructure projects are becoming crucial to meet rising demand. This trend could lead to a more balanced distribution of digital infrastructure across the UK.
