Pulsant is a UK-focused colocation and infrastructure-as-a-service provider operating a network of 14 regional data centres spread across England and Scotland, positioning itself as an alternative to congested and costly London data centre markets. Founded in 1995 (originally as EdNET, later Lumison), the company is headquartered in Maidenhead and has been owned by Antin Infrastructure Partners since 2021. Its differentiator is geographic breadth rather than hyperscale density: Pulsant markets itself as the most geographically diverse colocation provider in the UK, connecting its sites via a private, low-latency “Edge Fabric” network reaching 95% of the UK population, and in 2026 it completed a £10 million high-density data hall expansion in Milton Keynes aimed at AI, machine learning and accelerated-computing workloads.
Pulsant operates as a cloud provider and colocation provider, with facilities at the following locations:
