Solar Panels for Landlords & Rental Properties UK (2026)
Every privately rented home in England and Wales must reach EPC C by 1 October 2030, so many landlords are asking whether solar panels help. This guide covers how solar fits the new rules, who actually benefits (you or your tenant), whether you can raise the rent or charge for the power, the tax position, the grants open to landlords, what a rental install costs, and the practical checklist before you book one.

Should landlords install solar panels?
It depends on three things: where your EPC stands, who pays the electricity bill and how long you’ll keep the property. Solar is a strong move when the property needs help on the new smart readiness standard, when you pay the bills (an HMO or a bills-included let), or when you want a lower-bill home that lets faster and keeps good tenants. It’s a weaker move if the property still needs insulation first, if you plan to sell within a few years, or if the roof is shaded or north-facing.
Solar panels and the EPC C by 2030 rules
The government confirmed the new Minimum Energy Efficiency Standard for private rented homes in its Warm Homes Plan on 21 January 2026. It applies in England and Wales:
| Rule | What it means for you |
|---|---|
| Deadline | 1 October 2030 for all privately rented homes. The earlier idea of a 2028 deadline for new tenancies was dropped |
| Primary standard | Fabric performance: insulation, glazing, draught-proofing. Solar doesn’t help here |
| Secondary standard (your choice) | Heating system or smart readiness. Smart readiness rewards a home’s ability to generate its own power, usually from solar panels, and to use smart technology |
| Spending cap | £10,000 per property. Spending since October 2025 counts towards it. Homes worth under £100,000 have a lower cap of 10% of their value |
| Exemptions | A 10-year exemption if you’ve spent the cap without reaching the standard, plus exemptions for damaging works, solid wall insulation and third-party consent |
| Penalties | Up to £30,000 per breach, per property |
| New-style EPCs | Targeted from October 2026. Homes with an unexpired EPC C issued before 1 October 2029 get transitional protection |
The practical order is fabric first, then solar. Get an EPC assessor or retrofit coordinator to tell you what the fabric standard needs. If you then choose the smart readiness route, solar panels, ideally with a battery, are the obvious way to meet it, and qualifying spending counts towards your £10,000 cap. See solar panels and your EPC.
Who benefits: you or your tenant?
| Type of let | Who saves on bills | Who gets export (SEG) payments | Typical yearly value, 4kW |
|---|---|---|---|
| Single let, tenant pays bills | Tenant, about £500–£550 a year | Whoever registers, usually you as owner | ~£230–£250 export to you |
| Bills-included let | You | You | ~£730–£800 |
| HMO (more people home in the day) | You | You | ~£800–£900 |
Figures assume a south-facing 4kW system generating 3,800–4,200kWh a year, the October 2026 price cap of 26.32p/kWh and a 12p export rate. For a standard let where the tenant pays the bills, your return is mainly EPC compliance, the export payments, and a home that’s cheaper to live in, which helps it let faster and keep tenants for longer. The panels belong to you and stay with the property. See do solar panels increase home value and SEG tariffs compared.
Can you raise the rent or charge for the power?
Rent: since 1 May 2026, the Renters’ Rights Act means you can only raise the rent on a periodic assured tenancy once a year, using a section 13 notice with two months’ warning. The tenant can challenge it at the First-tier Tribunal, which judges it against the market rent. You can’t add a “solar surcharge” mid-tenancy, but a lower-bill home with a good EPC can support a market rent at the next annual review.
Charging for electricity: if you recharge tenants for electricity, for example in an HMO with a sub-meter, Ofgem’s maximum resale price rules limit what you can charge. Take advice before you try to meter or bill tenants for solar power. For most landlords it’s simpler to let tenants enjoy the lower bills, keep the export payments and treat the panels as part of the property’s value.
Working towards EPC C on a rental?
A vetted installer will size a system for the property, price it with or without a battery, and give you the MCS certificate your EPC assessor needs. It’s free, with no obligation.

A rental costs the same to fit as any other home, and 0% VAT applies to landlords too until 31 March 2027, because the relief is for residential homes, not owner-occupiers (VAT on solar panels).
| System | Panels | Typical installed price | With 5kWh battery | Typical property |
|---|---|---|---|---|
| 3kW | 7 | £4,500–£6,000 | £7,500–£9,500 | Terrace or small semi |
| 4kW | 9–10 | £5,500–£7,500 | £9,000–£11,500 | 3-bed semi, the typical single let |
| 6kW | 13–14 | £7,000–£9,500 | £10,500–£13,000 | Larger house or HMO |
Booking the install between tenancies avoids access problems and lets you fit bird mesh and check the roof while the house is empty. See solar panel cost UK and solar panel finance.
Are solar panels tax deductible for landlords?
- Not against rental income. Adding solar panels is an improvement, which counts as capital spending, so it can’t be deducted from your rental profits the way a repair can.
- No capital allowances on a let home. The Treasury has confirmed that “property businesses investing in plant and machinery for use in dwelling-houses cannot claim capital allowances on that expenditure”. That applies whether you own as an individual or through a company.
- Capital Gains Tax. As an improvement, the cost can usually be added to the property’s base cost, reducing the taxable gain when you sell.
- Export payments. Ask your accountant whether SEG income counts as part of your property business income.
- Commercial and mixed-use property is different. Panels on non-residential buildings can qualify for capital allowances (commercial solar).
This is general information, not tax advice. Check your own position with an accountant before you commit.
Grants for landlords
- Warm Homes: Local Grant. Run by councils in England, it lists solar PV as an eligible measure for privately rented homes where the tenant qualifies: typically a household income of £36,000 or less, or a means-tested benefit, in a home rated EPC D–G. Under the July 2026 guidance, the first property is fully funded and landlords pay 50% for each additional property. There’s no limit on how many properties you upgrade, within a £315,000 subsidy limit over three years. Tenants never pay. Ask your council whether its scheme is open.
- ECO4. Privately rented homes with low EPC ratings can qualify, but all ECO4 work must be finished by 31 December 2026 (ECO4 solar).
- Everyone else. 0% VAT until 31 March 2027, plus SEG export payments. Be wary of anyone offering “free panels for landlords” in exchange for leasing your roof, as it can complicate mortgages and sales (solar panel scams).

Landlord checklist before you install
- Tenant access. Agree dates in writing and give proper notice, or install between tenancies.
- Buy-to-let lender. Tell your lender. Panels you own outright are rarely a problem. Leased “rent-a-roof” panels often are.
- Landlord insurance. Add the panels to your buildings cover (solar panel insurance).
- Leasehold flats. You’ll need the freeholder’s consent for roof panels.
- Paperwork. Keep the MCS certificate (needed for the EPC and SEG), the datasheets and the workmanship guarantee in your property file.
- SEG registration. Register for export payments in your name and make sure there’s a smart meter (smart meters and solar).
- Tenant handover. Leave a one-page guide: run appliances in the day, how to read the monitoring, who to call about faults.
- Maintenance. As the owner, inverter faults and repairs are your responsibility. Budget £800–£1,500 for an inverter in 10–15 years (inverter replacement).
Do batteries make sense in a rental?
Tenants who work during the day use little solar power without one, so a battery raises their savings and strengthens the smart readiness standard. It adds about £3,500–£4,000 to a 4kW system. On a bills-included let or an HMO, where you capture the saving, a battery is usually worth it. On a standard let, weigh the extra cost against your £10,000 cap and what the EPC assessor says the property needs. See are solar batteries worth it and 4kW solar with battery.

The 2030 EPC C standard above applies to England and Wales. Scotland is setting its own energy efficiency standard for private rentals, so check the latest Scottish Government guidance. Home Energy Scotland no longer funds solar PV through its grant and loan (solar panels in Scotland). Northern Ireland has separate rules again. Whatever the nation, the practical points on this page still apply: who benefits, tax, consent and paperwork.
The bottom line on solar panels for landlords
Solar panels are a useful tool for meeting EPC C by October 2030 in England and Wales, through the smart readiness standard, once the property’s fabric is up to scratch. They make the most financial sense on bills-included lets and HMOs, where you keep the savings. On standard lets, the case rests on compliance, export payments and a more lettable home. The cost is capital, with no income deduction or capital allowances on a dwelling, but it can usually be added to your CGT base cost. Check whether your tenant qualifies for the Warm Homes: Local Grant, as your first eligible property can be fully funded. Install between tenancies if you can, and keep the MCS paperwork safe.

Solar panels for landlords: frequently asked questions
Do solar panels help a rental property reach EPC C?
They can, but not on their own. Under the rules confirmed in January 2026, rented homes in England and Wales must reach EPC C by 1 October 2030 by meeting a fabric standard first, then either a heating system or a smart readiness standard. Solar panels count towards smart readiness, but they don’t improve the fabric score, so insulation usually comes first. Landlords won’t have to spend more than £10,000 per property.
Are solar panels tax deductible for landlords?
Not against rental income. Installing solar panels is an improvement, so it counts as capital spending and can’t be deducted from rental profits. The Treasury has also confirmed that property businesses can’t claim capital allowances on plant and machinery used in dwelling-houses. The cost can usually be added to the property’s base cost for Capital Gains Tax. Check your position with an accountant.
Who gets the benefit of solar panels in a rented house?
If the tenant pays the electricity bill, the tenant saves on bills, typically £500–£550 a year from a 4kW system. The landlord, as owner, usually registers for Smart Export Guarantee payments worth around £230–£250 a year, and gets a better EPC. On bills-included lets and HMOs, the landlord keeps the whole saving, typically £730–£900 a year.
Can I put the rent up after installing solar panels?
Not straight away. Since 1 May 2026, under the Renters’ Rights Act, rent on a periodic assured tenancy in England can only be increased once a year using a section 13 notice with two months’ warning, and tenants can challenge it at the First-tier Tribunal against the market rent. A lower-bill home with a good EPC can support a market rent at the next annual review.
Are there grants for landlords to install solar panels?
Yes, if your tenant qualifies. The Warm Homes: Local Grant in England lists solar PV as an eligible measure for privately rented homes in EPC bands D–G where the tenant has a household income of £36,000 or less or a means-tested benefit. The landlord’s first property is fully funded and each additional property needs a 50% landlord contribution. ECO4 work must be finished by 31 December 2026.
Do I need my tenant’s permission to install solar panels?
You need your tenant’s cooperation for access, so agree dates in writing and give proper notice, or install between tenancies. You should also tell your buy-to-let lender and landlord insurer, and leasehold flats need the freeholder’s consent. Roof panels on houses are usually permitted development, so planning permission is rarely needed unless the building is listed.
