UK plans to mandate solar panels on most new homes to boost energy security and cut costs.

The UK's Energy Security and Net Zero Secretary Ed Miliband proposes that the "vast majority" of new homes in England may require solar panel installation. This follows Downing Street confirming the need for widespread solar panel installation on new properties. The policy, due to be detailed in the Future Homes Standard later this year, is expected to add £3,000 to £4,000 to construction costs but could save homeowners over £1,000 annually on energy bills.
