Warm Homes Plan 2026: What It Actually Means for UK Homeowners
The government published its £15 billion Warm Homes Plan in January 2026 — the biggest home energy upgrade programme in UK history. ECO4 ends next month. The Boiler Upgrade Scheme has been extended. And for the first time, there will be subsidised loans for solar panels. Here is what you can actually get, when, and whether it is worth waiting.

What is the Warm Homes Plan?
The Warm Homes Plan is the government's strategy to upgrade the UK's housing stock — most of which is old, draughty, and expensive to heat. Published on 21 January 2026, it replaces the patchwork of previous schemes (ECO4, GBIS, HUG) with a more unified approach.
The plan has three pillars:
1. An offer for everyone
Low-interest and 0% loans for solar panels, batteries, and heat pumps — available to all homeowners regardless of income. The Consumer Loans Scheme (launching April 2027) will provide up to £1.7bn in financing so you can spread the cost over time.
2. Direct support for low-income homes
£5bn for fully funded upgrade packages for eligible low-income households — covering insulation, heating, and potentially solar at no cost. This replaces ECO4 and the Home Upgrade Grant (HUG). Delivered through local authorities via the Warm Homes: Local Grant.
3. New standards for landlords
Mandatory minimum energy efficiency standards for all rental properties by 2030. Private landlords will need to reach EPC band C — expected to save renters an average of £210 per year.
ECO4 is ending — what does that mean for you?
The Energy Company Obligation (ECO4) — which has funded free insulation and heating upgrades for low-income and vulnerable households since 2022 — reaches its delivery deadline on 31 March 2026. The scheme will technically remain open until 31 December 2026 for remediation of non-compliant installations, but no new delivery targets will be set.
⏰ If you think you qualify for ECO4 — act now
ECO4 applications are still being processed, but energy suppliers are winding down their delivery. If you receive means-tested benefits and live in a poorly insulated home (EPC D–G), you may still be eligible for free insulation, a new boiler, or a heat pump. Contact your energy supplier or check gov.uk/apply-eco-help. Do not wait — once March passes, the replacement scheme details are still being finalised.
What ECO4 covered:
- Loft insulation, cavity wall insulation, solid wall insulation
- Underfloor insulation and room-in-roof insulation
- First-time central heating (including heat pumps)
- Boiler replacements for broken or inefficient systems
- Heating controls and smart thermostats
The replacement — the Warm Homes: Local Grant — will cover similar measures but be administered by local authorities rather than energy suppliers. Full eligibility details are expected in March 2026.
Heat pump grants: what is available right now
The Boiler Upgrade Scheme (BUS) is the one part of the Warm Homes Plan that is already running and fully operational. It has been extended to 2030 with a total budget of £2.7bn. Here is what you can claim:
| Technology | Grant amount | Notes |
|---|---|---|
| Air source heat pump (air-to-water) | £7,500 | Most common type. Replaces gas boiler, works with radiators. |
| Ground source heat pump | £7,500 | More efficient but needs garden space for ground loops. |
| Air-to-air heat pump | £2,500 | New in 2026. Provides heating and cooling. No radiators needed. |
| Biomass boiler (rural only) | £5,000 | Only available in rural areas off the gas grid. |
Key change: no more EPC barriers
Previously, you could not claim the BUS grant if your EPC had outstanding recommendations for loft or cavity wall insulation. This requirement has been removed. You can now apply for the heat pump grant regardless of your EPC recommendations. This is a significant change — it was previously blocking many homeowners, especially those with older EPCs that listed insulation as a recommendation even when it had already been done.
To apply, you need an MCS-certified installer to assess your home and submit the application on your behalf. The grant is deducted from the installation cost — you never handle the money directly.
A typical air source heat pump installation costs £10,000–£15,000 before the grant, so with the £7,500 BUS voucher you are looking at £2,500–£7,500 out of pocket. For more on real-world costs, see our guide to heat pumps and net zero.
Solar panel loans — the "rooftop revolution"
For the first time, the government is treating rooftop solar as a mainstream home upgrade rather than a niche product. The plan aims to triple rooftop solar capacity by 2030.
The main mechanism is the Consumer Loans Scheme, launching in April 2027 with up to £1.7bn in government-backed low-interest financing. This will allow homeowners to spread the cost of solar panels, batteries, and heat pumps over several years — with monthly repayments designed to be offset by energy savings.
What this means in practice
A typical 4kW solar system
Costs around £6,000–£8,000 upfront today.
With a 0% loan over 10 years: ~£50–£67/month
Typical energy saving: £60–£80/month
Solar + battery
Costs £9,000–£14,000 upfront today.
With a 0% loan over 10 years: ~£75–£117/month
Typical saving with smart tariff: £80–£120/month
Savings estimates based on 3,500 kWh generation, 50% self-consumption, Octopus Flux export rates. See our solar panels guide for detailed calculations.
The catch: the loan scheme does not launch until April 2027 — over a year away. If you are considering solar now, you will need to pay upfront or use existing personal finance options. For most homes, solar panels already pay back in 7–10 years without subsidised loans, so waiting is not necessarily the best strategy.

Free upgrades for low-income households
The Warm Homes Plan commits £5bn to fully funded upgrade packages for low-income and fuel-poor households. This is the direct replacement for ECO4 and will be delivered through two main channels:
Warm Homes: Local Grant
Replaces the Home Upgrade Grant (HUG). Administered by local authorities. Covers insulation, heating upgrades, and potentially solar for owner-occupiers and private tenants on low incomes. Expected to launch fully in 2026/27.
Warm Homes: Social Housing Fund
For council and housing association properties. Additional funding confirmed for 2026/27. Focuses on whole-street and whole-estate upgrades for maximum efficiency.
Who is likely to qualify?
Full eligibility criteria are expected in March 2026, but based on the plan document and existing scheme precedents, you are likely to qualify if:
- You receive means-tested benefits (Universal Credit, Pension Credit, Income Support, income-based JSA or ESA, Child Tax Credit, Working Tax Credit, Housing Benefit)
- Your home has an EPC rating of D, E, F, or G
- You are an owner-occupier or private tenant (with landlord consent)
- Your household income is below a threshold (to be confirmed — likely around £31,000)
💡 Middle-income "top-up" grants
For the first time, the plan indicates support for households above the low-income threshold. If you fall outside the poorest brackets, you may receive a partial grant covering a portion of the cost — similar to how the BUS grant works. Details are still being finalised, but this could make measures like solid wall insulation (typically £8,000–£22,000) much more affordable for middle-income homeowners.

Should you wait for the Warm Homes Plan or act now?
This is the question every homeowner is asking. The honest answer depends on your situation:
Act now if...
- • You qualify for ECO4 — apply before March while the scheme is still active
- • You want a heat pump — the £7,500 BUS grant is available right now
- • Solar panels already make financial sense for your home without subsidised loans
- • Your boiler has broken — do not freeze waiting for future grants
- • You are a landlord needing to reach band C — starting early spreads the cost
It may be worth waiting if...
- • You cannot afford solar upfront and want the 0% loan (April 2027)
- • You are on a low income and expect to qualify for a free upgrade package
- • You need solid wall insulation and hope for a top-up grant
- • Your home is already reasonably efficient and the upgrades are nice-to-haves
🤔 Our honest take
Do not let perfect be the enemy of good. Government schemes get delayed, watered down, or cancelled. The BUS grant is real, available, and generous. ECO4 is still running (just). If you qualify for either, apply now. The Consumer Loans Scheme sounds promising but is 14 months away and the details could change. If you are considering solar and can afford it, every month you wait is a month of energy savings you miss.

What landlords need to know
The Warm Homes Plan confirms that all privately rented properties must reach EPC band C by October 2030. This has been expected but is now official government policy backed by the plan document.
Key implications for landlords:
- Properties rated D or below will need upgrading before new tenancies from October 2030
- A cost cap is expected (likely £10,000–£15,000 per property) — if upgrades exceed this, you may be able to register an exemption
- The government is exploring financial support for landlords, but nothing concrete yet
- Social housing has separate (often stricter) standards under the Social Housing Fund
