Pulsant is a UK-only regional colocation and hybrid cloud provider that operates a network of 14 interconnected data centres spread across Scotland and England, linked by its own private network fabric it calls platformEDGE (formerly Edge Fabric). Rather than competing in London’s crowded core market, Pulsant deliberately positions itself as the UK’s most geographically diverse regional colocation operator, selling rack, cage and suite space alongside connectivity and infrastructure-as-a-service to more than 500-1,200 UK businesses as of 2025-2026. Headquartered in Maidenhead, Berkshire, the company traces its roots back to 1995/1996 as the ISP edNET, later rebranded Lumison, before becoming Pulsant through a series of acquisitions of regional operators including Onyx, ScoLocate and, most recently in 2025, two SCC-owned data centres in Birmingham and Fareham.
Pulsant operates as a cloud provider and colocation provider, with facilities at the following locations:

AI Data Centers
Pulsant's clearest AI-specific infrastructure is a purpose-built high-density data hall at its Milton Keynes site, completed in 2026 after a £10 million investment. The 1.2MW hall was designed specifically for AI, machine learning and accelerated computing workloads, targeting sectors like financial services, healthcare, biotech and gaming, and is pitched as a lower-cost, lower-latency alternative to space-constrained London facilities. It sits within the Oxford-Cambridge tech corridor and connects to Pulsant's wider 14-site UK network over a 400Gb-capable backbone.

Common Questions
Does Pulsant have facilities designed for AI or GPU workloads?
Yes. In 2026 Pulsant completed a £10 million, 1.2MW high-density data hall at its Milton Keynes (SE-1) facility specifically built for AI, machine learning and accelerated computing workloads, marketed as offering "sovereign compute" close to the Oxford-Cambridge tech corridor with roughly two milliseconds of latency to London Docklands and Slough.
How many data centres does Pulsant operate and where?
As of 2025-2026 Pulsant operates 14 data centres across the UK: three in the Edinburgh area of Scotland (South Gyle, Bankhead Medway and Newbridge), and eleven in England spread across Manchester, Rotherham, Newcastle (two sites), Maidenhead, Croydon, Fareham, Birmingham, Milton Keynes and Reading (two sites).
Is Pulsant just a colocation provider, or does it sell cloud too?
Both — Pulsant sells physical colocation (racks, cages, suites) at its 14 UK data centres and also sells its own IaaS/hybrid cloud product, Pulsant Cloud, delivered from the same facilities and connected via its platformEDGE network fabric.
How did Pulsant add its Birmingham and Fareham data centres?
Pulsant acquired both facilities from technology services provider SCC in a deal announced in March 2025, gaining the Cole Valley data centre in Birmingham (about 2MW capacity) and a carrier-neutral facility in Fareham (about 3MW capacity), each offering roughly 25,000 sq ft of white space.
