About 1,000 London buildings could be warmed by UK’s largest heat network

Westminster plan could see parliament warmed by waste and low-carbon heat from Thames, tube and sewers

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.
