Cadent Gas receives 38 applications for UK biomethane plants

March 16, 2026 |

In the UK, thirty‑eight applications have been lodged to build new or expand existing UK biomethane plants, representing one of the most substantial surges yet in new UK capacity of this renewable energy. Cadent, the UK’s largest gas distribution network, is now assessing these applications against its new ‘clustering’ approach.

The applications span Cadent’s UK area of operations, with 17 in the East of England, 13 in East Midlands, five in West Midlands and three in the North West.

This is the first set of projects to come forward under Cadent’s Ofgem‑supported cost‑sharing model, designed to reduce financial barriers by enabling developers in constrained areas to cluster and share reinforcement costs.

If taken forward, the projects would represent one of the most significant collective expansions of UK biomethane capacity to date.

Cadent already has 47 biomethane sites connected to its networks, delivering four terawatt hours (TWh) of energy, which equates to the annual gas usage of 351,000 homes. The company is aiming to grow this to 20TWh by 2035 – the annual gas usage of 1.8 million homes.
