The UK government has announced that ₤320 million will be invested over the next 5 years in schemes to support (local) district heat networks in cities. Heat networks are already used widely across Scandinavian cities to ensure space heating and hot water in buildings. The heat can be generated from various sources including large heat pumps, combined heat and power plants and deep geothermal plants but also from waste heat of factories and offices. The government sees a potential to reduce the heating costs by more than 30% for some households.
