A significant heat network project, the London Strategic Heat Main, has been awarded £41 million in government funding. This initiative intends to use recycled heat from sources such as data centres and factories to supply warm water to 650,000 homes throughout London. The system will transport this heat via a network of hot water pipes.
Project Scope and Funding
Andy Burnham backs London transport and housing boost
A 'London Deal' aims to grant the capital more devolved powers for growth and infrastructure projects.
The funding forms part of a broader £90 million government investment in heat networks across London. The initial phase of the London Strategic Heat Main is planned to extend across seven boroughs. These include Bexley, Greenwich, Lewisham, Southwark, the City of London, Lambeth, and Westminster. The project's reach could potentially expand further to include Barking, Dagenham, Tower Hamlets, and Kensington and Chelsea.
Ultimately, a purpose-built tunnel running alongside and beneath the River Thames is intended to carry hot water across the capital, distributing heat to properties along its route. During the tunnel's construction, the project plans to transport hot water over a distance of 15.5 miles (25km) daily using electric barges on the river.
Economic and Environmental Impact

London’s transport network will see permanent pedestrianisation on Camden High Street, limited Angel station exits on weekends, new electric buses on the 109/N109 route, a 5.8% fare rise and a long‑term City Thameslink closure.
Government ministers have indicated that this project could stimulate approximately £5 billion in investment for London's heat networks. It is also expected to create skilled employment opportunities in sectors such as tunnelling, engineering, and river transport. The government has reported that domestic heating currently accounts for about one-fifth of the UK's greenhouse gas emissions.
Energy minister Martin McCluskey stated that clean heat initiatives provide benefits to communities and support job creation. He added that building the necessary infrastructure is a form of reindustrialising the UK and deploying advanced energy technology. This aims to offer families lower energy bills, secure employment, and enhance energy security. For existing heat network users, upgrades to inefficient systems are planned to ensure they receive high-quality, affordable, and dependable heating.
Other Funded Projects
Other developments receiving government funding include a separate heat network in Bexley and Greenwich, which is set to serve up to 100,000 homes. Additionally, £11.4 million has been allocated for a heat system in the Marble Arch area. This system will utilise water-source heat pumps drawing energy from the London chalk aquifer to heat offices, homes, hotels, and businesses around Oxford Street. A further £5.5 million will support upgrades to systems serving 1,143 residents at Prospect House in Bermondsey and the Packington Estate heat network in Islington.
The completion of the London Strategic Heat Main project is anticipated by the early 2030s. The potential development of pontoons used for water storage into 'Thames Floating Gardens' has also been suggested, offering possibilities for new green spaces.
