nLighten UK Secures £50.7m to Expand Edge Data Centre Infrastructure

London-based nLighten UK Ltd has raised £50.7m in a new funding round, reaching an estimated post-money valuation of £125m. The company provides edge data centre infrastructure and colocation services to businesses that require localised data processing and hosting.

Incorporated in July 2022, nLighten UK operates as the British arm of a pan-European digital infrastructure platform. The company solves a critical bottleneck in modern cloud computing by focusing on edge facilities. Rather than relying solely on massive, centralised data centres, nLighten distributes its infrastructure across regional hubs, bringing compute power closer to end users. This physical proximity significantly reduces network latency for businesses, enabling faster data processing for applications such as artificial intelligence inference, smart manufacturing, and the rollout of next-generation connectivity services.

The latest corporate filings, submitted on 23 March 2026 following an allotment on 19 February 2026, confirm the £50.7m capital injection. This transaction values the UK entity at £125m post-money. While the specific investors for this exact equity allotment were not named in the local filing, the broader nLighten platform was established and is heavily funded by the global infrastructure investment manager I Squared Capital.

Building, acquiring, and upgrading data centres is a highly capital-intensive process, a reality reflected in the company's latest financial accounts. nLighten UK reported £2.9m in revenue alongside a net loss of £117,212. The UK corporate entity operates with a lean direct headcount of just two employees. This structure is common for infrastructure subsidiaries, where operational and site staff are often managed at the group level or retained within specific acquired facility companies.

This £50.7m round arrives during a period of unprecedented investment in British digital infrastructure. Following the UK government's recent decision to officially designate data centres as Critical National Infrastructure, billions of pounds have flowed into the sector. This designation provides operators with greater government support during critical incidents and helps streamline complex grid connection processes. Industry data from late 2025 indicated a UK data centre pipeline worth approximately £36.4bn in planned projects, covering nearly 100 developments across the country.

Furthermore, the government's recent push to establish regional AI Growth Zones has heightened the need for distributed compute power outside of traditional hubs like London. Edge data centre operators like nLighten are uniquely positioned to capitalise on this geographic shift. By acquiring existing regional facilities and upgrading them to handle the higher power densities and modern cooling requirements demanded by new technologies, the company is building the foundational infrastructure required to support the next generation of digital services across the UK.
