Is UK housing left behind on the way to net-zero?

British houses consume a majority of natural gas across all of the consuming sectors and contribute highly to greenhouse gas (GHG) emissions. When compared to France, UK gas consumption was up almost 30 per cent. The United Kingdom is one of many countries with an ambition to have legally binding net-zero emission by 2050 – or earlier. Since it is unlikely that all old British buildings will be replaced by new ones, which are going to be obliged to install low-carbon heating systems from 2025, is there something else to do in the meantime, except relying on financial support from Green House Grant?
