UK gas network connection requests rise among data centre developers

Recent data shows that UK gas networks received over 100 connection enquiries from data centre developers across 2024 and 2025, reflecting challenges developers face in accessing electricity grid capacity.

Over this period, networks processed 113 gas connection enquiries, attributed to delays in electricity grid connection availability. Figures from Future Energy Networks (FEN) indicate a rise in activity, with enquiries in 2025 approximately three times higher than the previous year.

Gas networks are currently handling 46 applications, indicating ongoing demand. Seven applications have been approved, representing around 15.4 terawatt-hours of energy capacity, which is estimated as sufficient to heat approximately 1.3 million homes.

Typical timelines for new gas network connections range from six to 24 months, compared with reported electricity grid connection times of up to 15 years. This difference in timelines has contributed to interest in gas connections for data centre developments.

Work is ongoing to explore ways to streamline gas connection processes. Options under consideration include the use of lower-carbon gases such as biomethane, alongside broader efforts to integrate electricity and gas systems to support energy system planning and development.

In parallel, data centre energy demand and infrastructure planning have been discussed in policy and industry forums, including an Environmental Audit Committee consultation.

Internationally, similar trends are being observed. In the United States, data centre expansion has been associated with increased gas demand, while in Europe, a gas-connected data centre has been launched in Ireland, reflecting evolving approaches to energy supply for digital infrastructure.
