Bunhill Heat and Power Network

Islington Council’s Bunhill Heat and Power Network (BHPN) is the first scheme in the world to take waste heat from an underground train network and use it to provide lower cost, greener heat to local homes, a school and leisure centres.

This ground-breaking scheme has the potential to be replicated not only across Islington and London but in any major city with an underground network. That’s because heat networks, such as BHPN, are able to harness a wide range of renewable and waste heat sources that are already available within a city.

This project is playing an important role in Islington’s commitment to reducing carbon emissions, helping lower heating bills, improving air quality and making the capital more self-sufficient in energy. Indeed, it forms an important part of the Mayor of London’s approach to decarbonising heat in London and helping London to become net zero carbon.

Islington Council has been at the forefront of action to reduce carbon emissions for many years. We are on target to reduce carbon emissions in the borough from 2005 levels by 40% in 2020 and, in June 2019, we declared a Climate Emergency and pledged to work towards making Islington net zero carbon by 2030.

BHPN links together the existing Bunhill phase 1 heat and power network with the new Bunhill phase 2 extension.

Why did we build it?

BHPN is one of many initiatives helping thousands of residents out of fuel poverty

How does it work?

This innovative project recycles waste heat from the London Underground to heat local homes
