Yes, Landlords Can Access Free Energy Grants
Landlords can get free or heavily funded energy improvements for rental properties — and for the main scheme, ECO4, it's the tenant's benefit status that matters, not the landlord's income. If your tenant receives qualifying benefits and the property has a low EPC, insulation and heating upgrades can be fully funded. This guide breaks the routes down scheme by scheme, and explains where a landlord contribution can apply.
ECO4 scheme for landlords
ECO4 is the UK's main energy-efficiency grant scheme, funded by the large energy suppliers rather than the taxpayer. It runs until 31 December 2026. For a privately rented home, eligibility works like this:
- Your tenant must receive a qualifying benefit — for example Universal Credit, Pension Credit (Guarantee or Savings Credit), income-based JSA, income-related ESA, Income Support, Housing Benefit or Child/Working Tax Credit.
- For a privately rented property the home must have an EPC rating of E, F or G (band D and above private rentals are generally excluded, as landlords are already expected to improve them).
- You provide written landlord consent for the work.
- Installation is designed to be at no cost to your tenant. Most measures are fully supplier-funded, but landlords can be asked to make a contribution towards certain measures — your installer will confirm before any work starts.
If your tenant doesn't claim benefits, you may still qualify through your council's flexible-eligibility route — see LA Flex below. Improving a rental's EPC rating also helps you meet the rules covered further down this page.
Landlord insulation grants and free measures
Through ECO4, the measures a landlord can typically have installed on an eligible rental include:
- Loft insulation (EPC boost: 1–2 bands)
- Cavity wall insulation (EPC boost: 1–2 bands)
- Solid wall / external wall insulation (EPC boost: 2–3 bands)
- Boiler replacement or first-time central heating (EPC boost: around 1 band)
- Solar panels, where the property is suitable (EPC boost: 1–2 bands)
Insulation is usually the biggest single win, both for your tenant's bills and for the property's EPC. See the full insulation grants guide for how each measure is assessed.
Warm Homes: Local Grant for rented homes
The Warm Homes: Local Grant is a council-delivered scheme in England, running from April 2025 to March 2028. It funds insulation, low-carbon heating and sometimes solar for lower-income households in homes rated EPC D–G. It can be used for privately rented homes — but the funding rules for landlords are different from owner-occupiers:
- One rental fully funded, then a 50% contribution. A private landlord can have one eligible property fully funded. For any additional properties in your portfolio, you must pay a 50% contribution towards the cost of the upgrades.
- Tenants pay nothing. Tenants are never asked to contribute towards the cost of the work.
- The tenant normally needs to be on a low income or receive means-tested benefits, and the property must be in England with an EPC of D–G.
Note: the Great British Insulation Scheme (GBIS) closed to new applications on 31 March 2026. LA Flex and the Warm Homes: Local Grant are now the live routes when a tenant doesn't claim benefits.
Grants when your tenant doesn't claim benefits
If your tenant isn't on qualifying benefits, the LA Flex route (also called ECO4 Flex) lets your local council refer low-income or vulnerable households into ECO4 using its own criteria — commonly where gross household income is under a set threshold. Thresholds and rules vary by council, so it's worth checking what your local authority accepts. The Warm Homes: Local Grant above is the other no-benefits route.
EPC rules and grants for landlords
Since April 2020, a privately rented home in England and Wales must have an EPC of E or above to be legally let (with limited exemptions). That is the rule in force today.
Looking ahead, the government has confirmed plans to raise the minimum standard for rented homes to EPC C, with a compliance deadline of 1 October 2030. This was set out in a government response published in January 2026 as part of the Warm Homes Plan, alongside a proposed cost cap of up to £10,000 per property. It is not yet law — the government is expected to lay the regulations in 2027, and the detail (including a new EPC metric) could still change. Treat EPC C by 2030 as a firm direction of travel to plan for, rather than a current legal requirement.
This is where energy grants for landlords matter: using ECO4 or the Warm Homes: Local Grant now can raise a poorly rated rental towards the coming standard at little or no cost, instead of self-funding the improvements later.
The Business Case
- Lower or no upgrade cost — grant funding can cover improvements you would otherwise self-fund.
- Get ahead of EPC C — improve the rating before the 2030 standard is expected to bite.
- Higher rent potential — energy-efficient homes can command higher rents.
- Tenant retention — lower bills tend to mean happier tenants who stay longer.
- Property value — a higher EPC supports a higher valuation.
