Low-carbon heating system to warm up London’s Square Mile

Scheme using boreholes to capture Earth's warmth will provide same heat as 2,300 homes with 50% less emissions

One of the UK's largest low-carbon heating systems will soon begin warming homes and offices in London's Square Mile by capturing heat from more than 650ft below the streets of the City.

The 4m scheme, to be housed in the historic Port of London Authority building on Charterhouse Street next to Smithfield Market, will provide the same amount of heat as used by 2,300 average UK homes with 50% less carbon emissions.
