Warm Homes Plan
The Warm Homes Plan launched in January 2026 as the largest home upgrade programme in British history. The scheme commits £15 billion over five years to upgrade 5 million homes with solar panels, battery storage, heat pumps, and insulation.
Low-income households with a total income below £36,000 per year can receive fully funded installations worth up to £30,000. Homeowners above this threshold will access government-backed loans from April 2027 at zero or low interest rates.
Boiler Upgrade Scheme (BUS)
The Boiler Upgrade Scheme provides fixed grants to replace fossil fuel heating with heat pumps. The scheme runs until 2030 with a budget of £295 million for 2025/26.

Check BUS eligibility requirementsSmart Export Guarantee (SEG)
The Smart Export Guarantee requires energy suppliers to pay solar panel owners for electricity exported to the grid. Rates vary by supplier, with the best tariffs currently paying 12-15p per kWh exported.
Households with battery storage can maximise SEG income by storing solar energy during the day and exporting during peak evening hours when rates are highest.
Warm Home Discount
The Warm Home Discount provides a one-off £150 rebate on electricity bills for households receiving qualifying benefits. From October 2025, an estimated 6 million households became eligible following removal of the "hard to heat" threshold.
This scheme operates separately from the Warm Homes Plan and does not fund installations.
Which Grant Can You Access?
Eligibility varies by scheme and household circumstances.
Low-Income Households
Households earning below £36,000 per year or receiving means-tested benefits (Universal Credit, Pension Credit, Housing Benefit) can access free upgrades through the Warm Homes Local Grant.

The Boiler Upgrade Scheme is available to all property owners in England and Wales, regardless of income. The £7,500 grant applies when replacing gas, oil, LPG, or electric heating with a heat pump.
From April 2027, the Consumer Loan Scheme will provide government-backed financing for solar panels and batteries.

MCS certification is mandatory for grant eligibility. Installations by non-certified contractors do not qualify for Boiler Upgrade Scheme or Warm Homes Plan funding.
Combining Grants and Finance
You cannot use multiple government grants for the same installation. However, you can combine:
- BUS grant + existing insulation funding (separate improvements are permitted)
- Free solar panels + paid battery upgrade (if solar is funded through Warm Homes Local Grant)
- Any grant + 0% finance for the remaining balance
Greentech Renewables offers 0% finance over 1-2 years on all installations. This allows you to spread the cost after grant deductions with no interest charges.
