Installing solar PV can simultaneously improve the EPC rating (boosting Band D towards Band C), reduce tenant energy bills, generate a small income via the Smart Export Guarantee, and increase long-term property value. With the government's stated aim of EPC Band C for all privately rented homes by 2030, solar PV is one of the most cost-effective improvement routes for properties where other measures such as insulation or heat pumps are not viable.
The regulatory landscape involves planning rules (usually permitted development, but not always), building regulations compliance (MCS certification), ECO4 grant eligibility, and tenancy agreement terms that clearly allocate the benefit of generated electricity between landlord and tenant.
Planning permission for solar panels on rental properties
Most solar PV installations on domestic rental properties qualify as Permitted Development — no planning application is required:
- Permitted Development rights (Class A): Solar panels on a house or bungalow roof qualify as PD if they project no more than 200mm beyond the roof plane, are no higher than the highest part of the roof (excluding the chimney), and are not on a wall or roof slope facing a road in a World Heritage Site
- Conservation areas: Panels on a roof slope or wall facing a highway are not PD in a conservation area and require a planning application
- Listed buildings: Almost always require listed building consent in addition to any planning permission. Check with the local planning authority before installing
- Flat roofs: Panels on a flat roof qualify as PD if they project no more than 1 metre above the flat roof and no higher than the highest part of the building. Flat roof installations in conservation areas still require a full planning application if visible from a highway
- Blocks of flats: The common parts of a block are not covered by domestic PD provisions. In practice, most flat roof installations on blocks require a planning application
- Always confirm current PD rules with the local planning authority before committing to installation
MCS certification and building regulations
For any solar installation intended to connect to the grid and access the Smart Export Guarantee, use an MCS-certified installer:
- MCS (Microgeneration Certification Scheme): An MCS-accredited installer is required for grid connection and grant funding. The installer provides an MCS certificate on completion
- Building regulations Part P: Electrical installation must comply with Part P. An MCS-accredited installer self-certifies compliance
- DNO notification: The installer notifies the Distribution Network Operator (DNO) for systems up to 3.68kWp. For larger systems, DNO permission is required in advance and can take several months
- EPC update: After installation, the EPC must be updated to reflect the solar PV — the new EPC will show the improved SAP score and, typically, the improved band
ECO4 funding for solar on rental properties
The Energy Company Obligation 4 (ECO4) scheme provides grants for energy efficiency improvements including solar PV for eligible households:
- ECO4 eligibility: The tenant must receive certain means-tested benefits (Universal Credit, Housing Benefit, Pension Credit, Child Tax Credit, Working Tax Credit, Income Support, or income-related JSA/ESA) — or the property must be EPC band D, E, F, or G
- What ECO4 funds: Solar PV is a funded measure under ECO4, usually as part of a package with insulation or other measures. The full cost can be zero to the landlord for qualifying households
- Great British Insulation Scheme (GBIS): A parallel scheme for Band D and E properties that can fund a single measure at lower cost
- Application process: Contact an ECO4-registered installer. The installer surveys the property and applies for the grant on the landlord's behalf. The tenant must consent
- Landlord consent required: ECO4 requires written landlord consent. If you agree, the installation becomes part of the property
Smart Export Guarantee — who receives the export payments?
The Smart Export Guarantee (SEG) pays for electricity exported to the grid. On a tenanted property, who benefits?
- Who holds the SEG contract: The SEG contract is held by the metered entity — typically whoever is responsible for the electricity supply account. If the tenant pays the electricity bill, they are the metered entity and receive the SEG payments (unless explicitly assigned)
- Landlord-owned meter: If the landlord pays utilities (common in all-inclusive-rent arrangements or HMOs with included bills), the landlord can hold the SEG contract and receive export payments
- Direct benefit to tenant: Where the tenant pays electricity, the tenant benefits from lower import bills (from self-consumption) and SEG export payments. The landlord cannot claim these benefits unless the tenancy agreement explicitly addresses allocation
- Best practice — addendum to tenancy: Include a solar PV addendum in the tenancy agreement confirming the installation, who benefits from generation and export, the tenant's obligations (not to shade or interfere with panels), and the maintenance process
- Current SEG rates (2026): approximately 4p–15p per kWh depending on the supplier. For a typical 4kWp system generating 3,800 kWh/year with 50% export, this is approximately £80–£300/year in export payments
EPC uplift from solar PV
Solar PV improves the SAP score used to calculate EPC ratings:
- A 4kWp system on a Band D property typically improves the SAP score by 8–15 points, which can move a property from Band D to Band C
- The improvement is larger for smaller, less well-insulated properties where the solar generation represents a greater proportion of total energy use
- Under SAP 10.2 (current methodology), PV panels receive credit for both self-consumed generation and exported electricity
- An updated EPC must be commissioned after installation — it is not automatic. The new EPC must be provided to any new tenant
- Band C compliance (expected 2030): Solar PV is likely to be one of the cheapest routes to Band C for Band D properties where loft insulation is already installed and wall insulation is impractical
What the tenancy agreement should cover
Your tenancy agreement or a dedicated addendum should address:
- Ownership: Confirm the solar panels are the landlord's property and part of the building. The tenant has no right to remove, modify, or redirect the system
- Access for maintenance: The landlord's right to access for annual servicing, inverter replacement, and panel cleaning (with appropriate notice)
- Benefit allocation: Explicitly state who benefits from generated electricity and SEG export payments
- Tenant obligations: The tenant must not shade the panels, hang items from the racking, or interfere with the inverter or wiring
- Repair: The landlord is responsible for repairing or replacing the system if it fails — inverters typically last 10–15 years; panels 25+ years
- Under the Renters' Rights Act 2025, a landlord cannot charge the tenant for the solar system installation as a default charge or as part of any permitted payment
Frequently asked questions
Do I need planning permission to install solar panels on my rental property?+
Usually not, for a standard house or bungalow. Most installations qualify as Permitted Development (PD) under Class A of Schedule 2 to the Town and Country Planning (General Permitted Development) (England) Order 2015, as long as panels project no more than 200mm beyond the roof plane. Listed buildings and properties in conservation areas face tighter restrictions and may need a planning application or listed building consent. Always confirm with the local planning authority for listed buildings or conservation area properties.
My tenant wants solar panels installed through ECO4 — do I have to agree?+
No, you are not required to consent. ECO4 requires written landlord consent before installation. However, if the tenant is in a Band D, E, F, or G property and receives a qualifying benefit, refusing free energy improvements may be relevant in future MEES enforcement proceedings. Free improvements that reduce tenant bills and improve the EPC are usually in the landlord's long-term interest. Review the proposed works carefully, confirm the installer is ECO4-registered and MCS-certified, and ensure your consent is in writing and specific about what is authorised.
Can I charge my tenant for the electricity generated by solar panels on the property?+
No, not as a direct charge for solar generation. The Tenant Fees Act 2019 prohibits charging tenants amounts other than permitted payments. If you supply electricity to the tenant from a landlord meter (common in all-inclusive-rent HMOs), you must charge no more than the tariff a licensed supplier would charge. You cannot charge a solar generation premium. In standard residential lets where the tenant pays their own energy bill, the solar benefit flows to the tenant directly through reduced import bills.
What happens to the solar panels if I sell the property?+
Solar panels are fixtures and form part of the building — they pass to the buyer on completion. The MCS certificate, installation documentation, and warranties (typically 25 years for panels, 5–10 years for inverters) should be included in the transfer of title. The SEG contract, if held by the landlord, must be transferred to the new owner by contacting the SEG licensee to transfer the account. If the tenant holds the SEG contract, the new landlord cannot claim those payments.
