Warm Homes Plan solar panels form the core of a new £15 billion UK government programme intended to permanently reduce household energy bills, improve housing quality and address fuel poverty across the country. Unveiled on 20 January 2026, the plan sets out a nationwide rollout of solar panels, heat pumps, batteries and insulation for millions of homes, backed by targeted grants, government-supported low-interest loans and tougher requirements for landlords. The WP Times reports, citing an official government press release.
What exactly the Warm Homes Plan is — in practical terms
The Warm Homes Plan is designed as a long-term national home upgrade programme rather than a short-term subsidy or bill support scheme. Its central objective is structural: to permanently improve the energy efficiency of Britain’s housing stock so that household energy bills fall sustainably, rather than relying on repeated government intervention during periods of high prices.
Government estimates indicate that up to five million homes could receive upgrades by 2030, with as many as one million families expected to be lifted out of fuel poverty over the same period. The programme blends large-scale public investment with private finance, with the stated aim of making technologies such as solar panels, heat pumps and home batteries a normal feature of UK homes rather than a niche option. Delivery sits with the Department for Energy Security and Net Zero, with regulatory oversight and scheme coordination linked to Ofgem through the creation of a new Warm Homes Agency, intended to streamline consumer advice, funding access and installation standards.
Why solar panels sit at the centre of the plan
Solar panels are placed at the heart of the Warm Homes Plan because they are seen by ministers as the quickest and most scalable way to deliver lasting reductions in household energy bills. Government analysis indicates that rooftop solar lowers reliance on grid electricity during peak price periods and provides the greatest financial benefit when paired with home batteries and electric heating systems such as heat pumps.
Ministers argue that consumer demand for home solar and low-carbon heating is already at record levels, reflecting rising energy costs and growing awareness of energy security. However, the upfront expense of installation continues to limit take-up, particularly among middle-income households that do not qualify for full grants. The Warm Homes Plan is designed to bridge that gap by spreading costs over time through government-backed finance. The strategy is underpinned by several explicit targets:
- Tripling the number of UK homes with rooftop solar by 2030
- Making solar panels a standard feature of new-build homes under the Future Homes Standard from early 2026
- Encouraging households to combine solar generation with batteries and heat pumps to maximise bill savings and reduce exposure to future price shocks
What support is available — and who it is aimed at
The Warm Homes Plan is structured around three distinct support routes, designed to reflect differences in household income, housing tenure and the ability to meet upfront installation costs. Together, they are intended to ensure that support reaches those most exposed to high energy bills, while also enabling working households and renters to access upgrades through a mix of grants, regulation and government-backed finance.
Fully funded upgrades for low-income households
Households on low incomes and those in fuel poverty will be eligible for fully funded home upgrade packages, backed by £5 billion of public investment. Support will be tailored to individual properties, reflecting differences in building type, insulation levels and heating systems.
The government’s illustrative example is a fully funded installation of solar panels paired with a home battery, covering the full average cost of £9,000 to £12,000. Additional measures, including insulation and smart heating controls, can also form part of the package. In the social housing sector, upgrades may be delivered on a street-by-street or estate-wide basis, an approach intended to reduce installation costs, minimise disruption and improve outcomes across entire communities.
Loans and grants available to all households
For households able to repay costs over time, the plan introduces government-backed zero and low-interest loans, designed to remove the barrier of large upfront payments. These loans will be available for:
- solar panels
- home battery storage
- heat pumps
They can be used alongside the existing £7,500 universal grant for heat pumps, and for the first time will also cover air-to-air heat pumps, which can provide cooling during hotter summer months. Ministers say the loans will be delivered through mainstream lenders, with government backing intended to keep interest rates low and terms accessible. Further details on eligibility and borrowing limits are expected later in 2026.
New standards for renters and landlords
The plan explicitly links home energy upgrades to minimum living standards in rented accommodation. Government data cited in the announcement states that 1.6 million children currently live in private rental homes affected by cold, damp or mould. From 2030, privately rented homes in England and Wales will be required to meet a minimum Energy Performance Certificate (EPC) rating of C, up from the current minimum of E. Landlords will be supported to meet the new standard over several years, with the government estimating that the reforms could lift around 500,000 renting families out of fuel poverty by the end of the decade.
What upgrades are covered under the scheme
The official list of measures eligible for support includes:
- solar panels (photovoltaic and thermal)
- heat pumps (air source, ground source and air-to-air)
- home and heat batteries
- smart heating and energy controls
- insulation (walls, floors and roofs)
- draught proofing
Delivery of these measures will be coordinated through a new Warm Homes Agency, which ministers say is intended to replace what they describe as a fragmented and complex system of overlapping schemes. The agency’s role will be to streamline consumer advice, funding access and installation standards, improving consistency and confidence for households.
How much households could save
Savings depend on property type, insulation level, tariffs and how technologies are combined. Government estimates cited alongside the plan suggest that for an average three-bedroom semi-detached home, installing solar panels, a battery and a heat pump could cut bills by around £500 a year. Independent bodies argue savings can exceed £1,000 annually in some cases.
Typical costs and savings (illustrative)
| Upgrade | Typical cost | Support mentioned | Likely impact |
|---|---|---|---|
| Solar panels | £5,000–£7,000 | Loans / grants | Cuts grid electricity use |
| Solar + battery | £9,000–£12,000 | Loans / fully funded for some | Larger bill reductions |
| Heat pump | £12,000–£13,000 | £7,500 grant + loans | Lower heating costs over time |
| Insulation | Varies | Free for eligible households | Immediate comfort gains |
What ministers and industry say
Prime Minister Keir Starmer described the plan as a shift in basic expectations: “A warm home shouldn’t be a privilege, it should be a basic guarantee for every family in Britain.”
Energy Secretary Ed Miliband said: “With this investment, we embark on a national project to turn the tide — waging war on fuel poverty.”
Energy companies, banks and consumer groups broadly welcomed the scale of funding, while stressing that delivery speed, installer capacity and electricity pricing will determine whether households feel the benefits quickly.
When changes will happen — key timeline
- January 2026: Warm Homes Plan published
- Early 2026: Future Homes Standard, including solar on new builds
- Later in 2026: detailed rules for low-interest loans and consumer access
- 2026–2030: large-scale rollout of upgrades across up to 5m homes
- By 2030: EPC C requirement for private rentals; target to lift 1m families out of fuel poverty
What households should take from this now
The Warm Homes Plan does not require households to act immediately, but it sets a clear direction. The government message is that structural upgrades, not temporary bill support, are the long-term answer to energy affordability.
For homeowners, the key decision will be when to combine solar panels, batteries and heating upgrades as finance becomes available. For renters, the plan signals higher minimum standards and a shift in responsibility toward landlords. In policy terms, the Warm Homes Plan is one of the most ambitious housing and energy interventions attempted in the UK. Its success will be judged not by the size of the budget, but by how quickly families see warmer homes and permanently lower bills.
