Warm Homes Plan & Local Grant 2026: Who Qualifies & How to Claim
With UK household energy bills remaining a top financial concern in 2026, thousands of homeowners and private tenants are checking their eligibility for the UK Government's Warm Homes Plan and Warm Homes: Local Grant. Designed to upgrade Britain's coldest, least energy-efficient properties, the Warm Homes Local Grant provides up to £15,000 for energy performance improvements (such as loft insulation, cavity or solid wall insulation, double glazing, and solar PV panels) plus up to £15,000 for low-carbon heating systems like air source heat pumps—delivered at zero cost to eligible low-income households.
Whether you own your home, rent from a private landlord, or are looking to replace an ageing gas boiler through the £7,500 Boiler Upgrade Scheme, this 2026 UK guide explains every active grant, income threshold, EPC requirement, and official application step.

Who Qualifies for the Warm Homes Local Grant in 2026?
Delivered through participating local councils across England, the Warm Homes: Local Grant targets households that struggle most with high winter heating costs. To qualify in 2026, your property and household must meet three core rules:
Property Energy Performance Certificate (EPC) Rating: Your home must currently have an EPC rating of D, E, F, or G. If you do not have a valid EPC, your local council or approved retrofit assessor can arrange an assessment during the application stage.
Household Income or Postcode Pathway: You can qualify through any one of three routes:
Income Threshold: A gross household income of £36,000 or less per year (adjusted upward in select high-cost areas or for larger households under local council criteria).
Eligible Deprivation Postcode: Living in an officially designated lower-income postcode area (Indices of Multiple Deprivation deciles 1–2), where income verification is streamlined.
Means-Tested Benefits: Receiving qualifying support such as Universal Credit, Pension Credit, Income Support, Housing Benefit, or Child Tax Credit.
Tenure Rules (Homeowners vs. Private Tenants):
Owner-Occupiers: Eligible for 100% funded upgrades up to the scheme caps.
Private Tenants: Eligible to apply with written landlord consent; landlords receive the first property upgrade free, with a required co-payment if upgrading multiple rental properties.
What Upgrades Are Covered Under the Warm Homes Plan?
Rather than offering a single one-size-fits-all measure, accredited TrustMark retrofit coordinators assess your home using a "fabric-first" approach so heat stays inside before installing new heating technology:
Insulation & Draught-Proofing: Loft insulation top-ups (to 270mm+), cavity wall insulation, external or internal solid wall insulation, underfloor insulation, and energy-efficient window/door upgrades.
Clean Heating Systems: Air source heat pumps, high-efficiency electric storage heaters, and zoned smart heating controls.
Solar Panels & Battery Storage: Rooftop solar PV installations (and paired battery systems in eligible retrofit packages) to slash daytime electricity bills.

Warning: How to Spot Warm Homes Grant Scams in 2026
Because government energy grants attract aggressive cold-callers and misleading social media adverts, protect yourself with three simple rules:
Never Pay an Upfront "Admin" or "Survey" Fee: Legitimate Warm Homes Local Grant and ECO4 assessments arranged through your council or energy supplier are 100% free.
Verify TrustMark Registration: Every contractor installing grant-funded insulation, solar panels, or heat pumps must hold active TrustMark and MCS (for heat pumps/solar) accreditation.
Beware of Unsolicited Doorstep Knockers: Always initiate your application directly through GOV.UK or your official local council website rather than signing paperwork at the front door.
Frequently Asked Questions (FAQ)
Do I have to pay back the UK Warm Homes Local Grant?
No. The Warm Homes: Local Grant is a non-repayable government grant, not a loan. Eligible homeowners pay £0 toward approved energy performance and clean heating upgrades within the scheme funding caps.
Can I get a free heat pump in 2026 if my income is over £36,000?
If your household income exceeds the Warm Homes Local Grant limit and you do not live in an eligible postcode, you can still claim a £7,500 flat discount toward an air source or ground source heat pump through the Boiler Upgrade Scheme (BUS) in England and Wales, regardless of household income.
