Gas networks received well over 100 connection enquiries from data centre developers in 2024 and 2025, new figures have revealed. Over the two year period, networks considered a total of 113 enquiries regarding data centre gas connections as a result of the significant delays developers are encountering in securing access to the electricity grid.
Published by Future Energy Networks (FEN) – the representative body for the UK gas networks – the figures demonstrate how enquiries have risen exponentially, with around three times as many submitted in 2025 compared to 2024.
James Earl, CEO of Future Energy Networks (FEN), said: “The dramatic increase in the number of data centre enquiries to gas networks reflects the long delays developers are encountering in accessing the electricity grid. If we are to get ahead in the global AI race, bolster economic growth and secure future investment, we must harness the immense potential of both gas and electricity systems.
“Gas networks stand ready to support the AI revolution in ways which both bolster the UK’s burgeoning tech industry while remaining on track to decarbonise our energy system.”
Gas networks are currently processing 46 applications from data centre developers, highlighting sustained momentum across the sector and the need to work hand in hand with the power grid to build energy resilience for the expanding digital economy.
Seven applications have been secured for connection to the gas network equalling a combined capacity of 15.4 terawatt-hours, enough energy to heat 1.3 million homes.
New demand connections to the gas network typically take six to 24 months, while developers can face a wait of up to 15 years for access to the electricity grid. Securing a gas connection is generally quicker than constructing a data centre, meaning that connecting to the network shouldn’t result in delays.
Energy leaders are actively exploring ways to streamline the delivery of gas connections for data centres. The use of green gases, such as biomethane, is one consideration, which would support the dual objectives of driving economic growth while accelerating the decarbonisation of the energy system. The most advanced solutions focus on integrating electricity and gas systems, unlocking greater value from new developments for the wider energy ecosystem.
The figures come as senior politicians grapple with the challenge of how to power data centres, with an Environmental Audit Committee consultation on the sustainability of data centres recently closing.
The trend mirrors global developments, with rising gas demand in the United States linked to rapid data centre expansion and the recent commissioning of Europe’s first gas-connected data centre in Ireland.
