Heat from sewers, tube and Thames could soon warm London buildings

Westminster plan for UK's biggest heat network could involve parliament warmed by waste and low-carbon heat

About 1,000 London buildings including the Houses of Parliament and the National Gallery could soon be warmed by low-carbon heat sourced from the River Thames, London Underground and sewer networks.

Plans to develop the UK's biggest heat network to supply decarbonised heat to buildings across Westminster were set out on Wednesday by the government as part of its pledge to back seven heat network zones with more than 5m of public funding.
