Warm Homes Plan: Eligibility & How to Apply

How Warm Homes Plan funding eligibility really works

The first thing to understand about Warm Homes Plan funding eligibility is that there is no single test. The Warm Homes Plan is the government’s flagship home-energy programme, a major multi-year investment aimed at upgrading millions of homes, but it is an umbrella rather than one grant. It funds several separate schemes, and each one decides eligibility on its own terms. So the honest answer to “do I qualify for the Warm Homes Plan?” is “for which part?”, because you could be a clear yes for one route and out of scope for another.

That is good news more often than people expect. A common reason eligible households never apply is the assumption that grants are only for people on benefits. Some routes are benefit-led, but others turn on your Council Tax band and EPC, or simply on the fact that you are replacing an old boiler. This guide walks through the tests that actually decide each route, then explains how to apply, and finishes on how to tell a legitimate route from a scam. Treat the specifics as illustrative and confirm anything that affects you against the live gov.uk eligibility checker before committing.

The tests that decide each route

ECO4: benefits plus a poorly performing home

ECO4 is the fully funded, whole-house route, and it is the most strongly means-tested. To qualify, a home generally needs to be in EPC band D to G and occupied by a household on a qualifying means-tested benefit. The qualifying benefits commonly include Universal Credit, Pension Credit, income-based Jobseeker’s Allowance or Employment and Support Allowance, Income Support, Housing Benefit and Tax Credits. Where a home qualifies, ECO4 can fund insulation, first-time central heating, heating upgrades, heat pumps and solar PV at no cost, often as several measures bundled together.

The Great British Insulation Scheme: two doors, one of them benefit-free

The Great British Insulation Scheme funds a single insulation measure and is the route most people overlook, because it has a General Group that needs no benefit at all. The Low-Income Group uses the same means-tested benefits as ECO4 and is open to any Council Tax band. The General Group is open to homes in Council Tax bands A to D in England (A to E in Scotland and Wales) with an EPC of D or below. If you work, are not on benefits and live in a typical mid-band home that is poorly insulated, the General Group is the door to check first.

The Boiler Upgrade Scheme: no income test at all

The Boiler Upgrade Scheme has the simplest eligibility of the four. It is open to any homeowner in England or Wales replacing a fossil-fuel, or non-heat-pump electric, heating system, regardless of income or benefit status. The grant pays 7,500 pounds towards an air source or ground source heat pump, with separate grant amounts available for some other low-carbon systems such as biomass boilers; check current rates on gov.uk. The main conditions are practical: the installer must be MCS-certified and a member of an approved consumer code, either RECC or HIES.

The Warm Homes: Local Grant: income-led, council-delivered

The Warm Homes: Local Grant is run by local authorities and aimed at lower-income owner-occupiers and private renters in England in EPC band D to G homes. Eligibility typically turns on a household income and savings test, though postcode or qualifying-benefit routes can override the income line. The exact thresholds can change, so check the current limits on gov.uk. Because councils deliver it, the exact criteria and roll-out can vary by area, so your local authority’s apply page is the definitive source.

What about renters, landlords and businesses?

Private renters are eligible for several routes, including ECO4, the Local Grant and the Great British Insulation Scheme, usually with landlord consent because the measures are physical building improvements. Landlords also have an incentive of their own, since Minimum Energy Efficiency Standards already restrict letting the worst-rated properties. Businesses and commercial landlords mostly sit outside the domestic grant schemes; their main funding route is capital allowances, with the 100 percent Annual Investment Allowance letting a business write off qualifying plant such as heat pumps and solar PV. The Boiler Upgrade Scheme does, however, cover small businesses replacing a fossil-fuel system.

How to apply, route by route

Once you know which door fits, the application path follows from the scheme.

For ECO4 and the Great British Insulation Scheme, you apply through an obligated energy supplier, the gov.uk eligibility checker, or a TrustMark-registered installer who can confirm your eligibility and lodge the work. For the Boiler Upgrade Scheme, the process is reassuringly hands-off: your MCS-certified installer applies for the grant on your behalf and deducts it from their invoice, so you only ever pay the balance. For the Warm Homes: Local Grant, you apply through the gov.uk apply page or directly to your local authority, not your energy supplier.

A practical sequence that works for most people: check your EPC band and Council Tax band, note whether anyone in the household is on a qualifying benefit, then run those facts through the gov.uk eligibility checker for the scheme that looks closest. If you are unsure which scheme to start with, our grants and funding guide maps all of them, and you can tell us about your home for a steer toward the right route. The savings calculator can help you weigh which measures matter most for your property.

Deadlines, because timing affects eligibility

Eligibility is not only about who you are; it is also about when you apply. ECO4 and the Great British Insulation Scheme are both time-limited and closing to new measures, so confirm the current deadlines on gov.uk and Ofgem. The direction of travel is for the Warm Homes Plan delivery model to replace the supplier-obligation route, with funding flowing through the Local Grant, the Boiler Upgrade Scheme and a new low or zero-interest finance route instead. If a closing scheme fits you, the window is real, so it is worth confirming your position promptly. Because these dates can move, always verify them on the live gov.uk page for the scheme.

Applying safely

The accredited route is also your protection. Legitimate schemes never cold-call demanding upfront payment, and grants like the Boiler Upgrade Scheme are deducted at source, so you never receive or hand over the money. Always check an installer’s TrustMark and MCS registration before signing anything, and if a “free grant” offer pressures you for bank details on the doorstep, walk away. For a fuller picture of where grants end and other support begins, see our cost guide, and for the detail on the closing supplier-funded insulation route, our Great British Insulation Scheme page sets out the two groups in full. Everything here is general guidance; your eligibility and any funded amount depend on your property and the live scheme rules when you apply.
