Landlord Solar Grants & Funding 2026

Is there a grant for solar panels for landlords?

The honest answer is that solar panels for landlords are not directly grant-funded. There is no scheme that simply pays for a landlord’s array. What does exist is a stack of grants, allowances and income schemes that subsidise the wider journey to EPC C and make the solar spend work harder, and knowing which ones you can actually claim, and which run to your tenant rather than to you, is worth real money in 2026.

This matters now because, through its Warm Homes Plan, the government has signalled tighter minimum EPC standards for privately rented homes in England, expected to move toward an EPC C minimum later this decade with a per-property cost cap on the works required. The exact band, deadline and cap have shifted before, so check the current MEES timeline and cost cap on gov.uk. For the large stock of sub-C rental homes that makes EPC a capital-planning question. Solar alone moves the fabric-based EPC less than insulation does, so the smart approach is to combine a modest array with the cheapest fabric measures and then stack whatever funding you qualify for. The schemes below are the ones that matter to landlords.

The Smart Export Guarantee (SEG)

For a landlord whose tenant pays the electricity bill, the Smart Export Guarantee is one of the very few direct cash returns from the array. It pays the named account holder for surplus electricity exported to the grid, typically 3 to 15p per kWh in 2026. Rates are supplier-set with no government-mandated minimum, so it pays to compare suppliers.

Two conditions matter. The system must be MCS-certified, up to 5 MW, with a smart meter capable of half-hourly export readings. And the income accrues to whoever holds the account, so where the system is in your name as landlord, you keep the export income rather than the tenant. Registering the system to the landlord, where appropriate, is one of the simplest ways to turn a tenant-pays property into one that returns at least some cash. The detail is on the Smart Export Guarantee pages at Ofgem.

The Boiler Upgrade Scheme (BUS)

The Boiler Upgrade Scheme is the most useful direct grant available to landlords, and it pairs naturally with solar on off-gas stock. It is open to all property owners in England and Wales, including private and portfolio landlords, with one grant per property and no cap on the number of properties.

What it is worth

The grant is £7,500 for an air source or ground source heat pump. Grants may be higher for off-gas oil or LPG homes or other heat pump types, and the eligibility rules have been widened over time, so check the current rates and conditions on gov.uk. The install must be carried out by an MCS-certified installer and must replace a fossil-fuel heating system.

Where it fits a landlord’s strategy

Off-gas rural lets heated by oil or LPG have the worst EPCs and the highest tenant bills, so the band uplift is largest there. A heat pump funded by BUS, combined with a 4 to 6 kW solar array that offsets part of the heat pump’s electricity demand, is one of the strongest compliance packages for that stock. Watch the electrical supply, though: combining solar, a heat pump and possibly an EV charger can require a DNO supply check on older single-phase connections. The scheme is set out on the Boiler Upgrade Scheme page at GOV.UK.

Capital allowances for incorporated portfolios

For limited-company landlords this is the genuine tax route on the solar spend itself, and it is the one most often missed. If your portfolio is held in an SPV paying corporation tax, solar PV qualifies as plant and machinery. The Annual Investment Allowance gives 100% relief on the first £1m of qualifying expenditure, and the 50% First Year Allowance can apply above that cap. In practice this can mean an effective corporation-tax saving of around 25% on qualifying spend in year one.

The crucial caveat is structure. This applies to incorporated portfolios only. Personally-held residential lets cannot claim capital allowances on solar at all: the furnished holiday let regime and its allowances were abolished from April 2025, leaving only Replacement of Domestic Items Relief on furnishings. Many landlords incorporated after Section 24 restricted mortgage-interest relief, so a lot of portfolios can use this, but it must be confirmed with the company’s accountant. Background is on the capital allowances guidance at GOV.UK.

Tenant-led schemes you cannot claim directly but can unlock

Two further schemes are tenant-driven. You cannot claim them as the landlord, but eligible tenants can unlock funded upgrades on your property with your consent, which subsidises the route to band C on lower-income tenancies.

ECO4 (Energy Company Obligation)

ECO4 is time-limited and is tenant-driven, not landlord-driven, so confirm the current deadline on gov.uk. The tenant must receive a qualifying means-tested benefit or be referred via LA Flex, and the landlord must give consent and cannot charge the tenant for the work. It funds insulation and heating measures, fully or partly, though landlords may be asked to contribute toward more expensive measures. The benefit must flow to the occupant. Used well, it is a route to subsidised fabric and heating that you can stack with self-funded solar to reach band C. The scheme detail sits on the Energy Company Obligation (ECO4) page.

Warm Homes: Local Grant

The Warm Homes: Local Grant covers England only and is time-limited, so confirm the current deadline on gov.uk. It is tenant-led: a privately renting tenant applies, with the landlord’s permission, where the household is on a lower income or a means-tested benefit and the property is a lower EPC band, with the exact income threshold and qualifying bands set on gov.uk. Tenants do not contribute to the cost. Landlords cannot claim directly, but eligible tenants can unlock funded energy-efficiency and low-carbon heating measures through the local authority, again subsidising the EPC C journey on lower-income tenancies.

How to stack funding around solar in practice

The pattern that works is to treat solar as the income-and-resilience layer and grants as the way to subsidise everything around it. Establish who pays the bill, model the cheapest combination of fabric measures and a modest array that clears band C inside the applicable cost cap, then layer funding: BUS where a heat pump is in scope, capital allowances if you are incorporated, SEG export income registered in your name, and tenant-led ECO4 or Warm Homes: Local Grant where the occupant qualifies.

Qualifying works done now generally count toward any cost cap once standards tighten, so works you do today are not wasted, and acting early beats the installer bottleneck that will build before any deadline. Check on gov.uk how the cost cap and qualifying dates currently apply. Our grants and funding page keeps the current figures together, the cost guide shows where each scheme changes the net spend, and the savings calculator lets you model a property.
