The government is being urged to end the “absolute scandal” of new homes being built without solar panels.
Doing so would cut both household bills and greenhouse gases that cause climate change, the Local Government Association (LGA) said in a new report.
Just four in 10 new homes in England come with solar power, according to separate figures from the industry body Solar Energy UK.
Although that is a significant three-fold increase over the space of a year, the LGA said making it mandatory would benefit bill-payers and the climate for years to come, saving people £440 per year.
The UK lags behind its neighbours in the European Union, which last year adopted new legislation demanding all new residential buildings come with solar panels from 2030.
Greenpeace UK called it an “absolute scandal that homes are built without rooftop solar panels in this day and age”.
Its campaigner, Lily Rose Ellis, said: “Given the soaring cost of electricity, our desperate need to cut planet-heating emissions, and the relatively low cost of installation to housebuilders, solar panels on all new builds should be mandatory.”
Last year, Labour promised a “rooftop revolution” that would see millions more homes fitted with solar panels.
But they have been accused of wavering over proposals to make it mandatory, as it also courts the house-building industry to help it meet its target to build 1.5 million homes during this parliament.
The LGA wants the government to allocate them long-term funding in the upcoming spending review so they can help the country meet net zero.
