The government is expected to allocate up to £13bn over the next four years to cut emissions, support green energy and reduce bills.
Energy secretary Ed Miliband is set to announce plans next month for new “zero bill” homes, including grants for solar panels, heat pumps, and battery storage.
The “warm homes fund” aims to significantly reduce energy costs for millions of homeowners, with some potentially paying little to nothing for their energy.
Ministers are also considering easing restrictions on plug-in solar panels and developing schemes with banks to allow installations with no upfront costs, repaid over five to ten years.
Poorer households are expected to receive the most assistance with initial expenses, and experts suggest many homes could achieve near-zero energy bills.
