Solar Panels for Landlords: Is It Worth It?
The question of solar panels on rental properties is more nuanced than for owner-occupied homes. As a landlord, you face different financial incentives, different regulatory considerations, and different operational challenges. This guide sets out the honest business case for solar on rental properties in 2026, based on our experience installing on both residential and HMO properties across the North East.
Who Owns the System — and Who Benefits?
The key decision in rental property solar is ownership. Under the most common arrangement:
- Landlord-owned solar: You pay for the installation, own the system, and either benefit from reduced electricity bills (if on a landlord all-inclusive deal), or the tenant benefits from reduced bills directly. SEG payments go to whoever's name the electricity account is in — typically the tenant if they pay their own bills.
- Shared benefit arrangement: Some landlords include the solar generation benefit in reduced rent, or ring-fence the SEG income to offset service charges in a block.
For buy-to-let properties where tenants pay their own electricity bills, the direct financial return to the landlord is mainly indirect: improved property desirability, higher EPC rating (which may allow higher rents), and reduced risk of void periods as energy-efficient properties are increasingly preferred by tenants.
EPC Rating and Minimum Energy Efficiency Standards
The UK government has proposed (though not yet enacted at time of writing) raising the minimum EPC rating for rental properties to 'C' by 2028. Many older rental properties currently sit at EPC D or E. Solar panels contribute directly to EPC improvement — a well-sized solar system can often lift a D-rated property to C, meeting the proposed upcoming standard. Proactively installing solar now may avoid compliance costs later and protect rental income.
HMO Properties
Houses in Multiple Occupation present a strong case for landlord solar installation, since the landlord typically pays the electricity bill on a shared house. A 4–6kW solar system on an HMO property with high daytime occupancy can generate annual savings of £800–£1,400 directly to the landlord's electricity bill. With battery storage, the benefit extends into the evening when occupancy is highest.
Planning Considerations
Solar installation on rental properties follows the same Permitted Development rules as owner-occupied properties — no planning permission required in most cases. However, if the property is in a conservation area or is listed, the same planning considerations apply. We handle all planning queries as part of our free survey service.
Section 24 and Energy Costs
The restriction on mortgage interest relief under Section 24 has made the efficiency of every cost item in a buy-to-let portfolio more important. Solar panels that directly reduce a landlord's electricity bills (on HMOs or properties on landlord-supply deals) reduce a genuine operating cost. Unlike mortgage interest, which Section 24 limits, maintenance costs and property improvements that generate energy savings are treated differently — always confirm the tax treatment with your accountant, but the general principle is that energy cost savings directly improve net operating income.
Tenant Engagement and Contracts
For standard lets where tenants pay their own bills, the practical arrangements need to be clear in the tenancy agreement:
- Who registers for the SEG tariff? (The occupier of the property whose name the electricity bill is in.)
- What happens to the SEG income? (Typically the tenant's — this should be stated in the tenancy agreement.)
- What maintenance obligations exist? (Annual inspection is good practice — define who commissions it.)
- What access rights does the landlord have for maintenance? (Standard tenancy provisions apply.)
For landlords who want to retain SEG income, a landlord-supply deal where the landlord pays the electricity bill and charges the tenant an inclusive utility rate is the cleanest arrangement — but comes with administrative complexity. Most landlords simply allow the tenant to benefit from solar savings as part of the property's value proposition.
Battery Storage on Rental Properties
Adding battery storage to a rental property with solar is increasingly worth considering for HMOs and landlord-supplied properties. A 9.5kWh battery on an HMO property can add £350–£550 to annual electricity bill savings. For a landlord paying a combined electricity bill of £2,000–£4,000/year on a 5-bedroom HMO, a battery payback of 8–10 years is achievable with the full saving accruing to the landlord. ALPS Electrical installs battery storage on landlord properties across Teesside and the North East.
The Investment Case
For HMOs or properties where the landlord pays electricity: payback of 5–8 years, with 17–25 years of reduced bills thereafter. For standard lets with tenants paying bills: return via improved EPC, higher rental value (typically £50–£100/month premium for energy-efficient properties), reduced void risk, and early compliance with likely forthcoming minimum EPC requirements. Neither case is speculative — both deliver clear, computable returns. Contact ALPS Electrical for a landlord solar assessment in the North East.
