The Solar Roadmap, published in June 2025, called for a "rooftop revolution", deploying solar PV on homes and buildings to cut bills, improve energy security and create thousands of highly skilled jobs across the country1. The document is cited in the government's Warm Homes Plan, which restates that ambition alongside a wider package of home upgrade measures1.
The Warm Homes Plan sets out £15 billion of public investment to upgrade up to 5 million homes and lift up to a million families out of fuel poverty by 20301. Its consumer offer includes £2.7 billion for the Boiler Upgrade Scheme to 2030, £2 billion for consumer loans, £5 billion for low-income schemes, £1.1 billion for heat networks and £2.7 billion of innovative finance through the Warm Homes Fund1. The plan states that installing solar, batteries, heat pumps and insulation can save families hundreds of pounds a year on their bills1.
"The Solar Roadmap, published in June 2025, called for a 'rooftop revolution', deploying solar PV on homes and buildings to cut bills, improve energy security and create thousands of highly skilled jobs across the country."
The plan says the rooftop revolution could triple the current number of homes generating their own energy with solar panels by 20301. It also confirms plans to implement the Future Homes Standard in Q1 2026, so that new homes are built with solar and clean heating installed as standard1. On bills, it states that the 2025 Autumn Budget took an average of £150 of costs off energy bills from April 20261.
| Measure | Figure stated in the plan |
|---|---|
| Total public investment | £15 billion |
| Homes to be upgraded by 2030 | Up to 5 million |
| Households lifted out of fuel poverty by 2030 | Up to 1 million |
| Boiler Upgrade Scheme funding to 2030 | £2.7 billion |
| Consumer loans | £2 billion |
| Low-income schemes | £5 billion |
Why it matters for households
For a household, the plan's framing is that solar panels, batteries, insulation and heat pumps can cut bills and reduce exposure to international fossil fuel markets1. The plan describes clean power and electrification in the home as swapping reliance on fossil fuels for homegrown power, and says support is intended to reach every kind of household, whether owned, privately rented or social housing1. It states that homeowners could receive grant support for clean heating or low-cost finance for a solar or battery installation, and that new build buyers would get solar panels and clean heating as standard1. The plan also confirms new minimum energy efficiency standards that privately rented properties will need to meet by 20301. Details of how individual households would access solar finance, and what the loan terms would be, have not been reported in the plan text cited here1.
What happens next
The plan confirms implementation of the Future Homes Standard in Q1 20261. A consultation on alternative heating technologies opened on 18 November 2025 and runs until 10 February 20261. The Great British Insulation Scheme ends as planned on 31 March 20261. DESNZ has consulted on extending ECO4 by nine months, to end on 31 December 2026, without increased delivery targets or impacts on consumer bills1. A Call for Evidence will launch early in 2026 on where else the Warm Homes Fund can deliver greatest impact, and government is consulting on secondary legislation intended to take effect in 2027 requiring smart functionality in heat pumps and electric heating appliances in scope1. The UK Cooling Outlook is due in 2026, and a fourth National Adaptation Programme is due in 20281.
