Solar and EPC ratings: a checklist for Three Rivers landlords

No. An Energy Performance Certificate assesses a property using a defined methodology. Solar may contribute to the assessment, but a specific panel system does not guarantee an uplift to a particular band. Start with the current certificate and a qualified assessor’s advice.

Ask the assessor which measures are appropriate for the building and how the proposed system would be evidenced. Installing equipment first and hoping it produces the required result can leave a landlord with further work still to arrange.

The GOV.UK landlord guidance checked on 8 September 2026 describes the current minimum standard of EPC E for covered domestic private rented properties in England and Wales, subject to the applicable rules and exemptions. It also addresses long-term standards separately.

Use the latest official guidance when making a decision. A future policy announcement should not be confused with the requirements currently applying to a tenancy. Where the property’s legal position is unclear, take advice from an appropriately qualified professional.

Review insulation, heating and other recommended measures alongside solar PV. Solar generates electricity; it does not repair a leaking roof, remove draughts or correct an unsuitable heating design. An improvement plan should respond to the building’s actual weaknesses.

Coordinate roof work and the solar installation where appropriate. Ask for the assessment and installation sequence to be documented so that one measure does not create avoidable work for the next. Keep evidence of the completed specification for the assessor.

Clarify who pays the electricity bill, who owns the equipment and who receives export payments. A tenant can use electricity generated at the property only where the electrical and contractual arrangement allows it. A shared roof needs particular care.

Discuss access, disruption, operation and fault reporting with the tenant. The owner should understand the ongoing maintenance obligation and the procedure if the tenant changes. Include monitoring-account access and privacy in the handover arrangements.

Three Rivers publishes Warm Homes Local Grant information with conditions for rented properties. Check the current scheme criteria, landlord requirements and whether an assessment can be offered. A general reference to solar support is not confirmation that a specific landlord or installation qualifies.

Do not commission work on the assumption that it will be reimbursed later. Follow the scheme’s application route and obtain any required approval first. A self-funded installer enquiry through this site follows a separate process.

Keep the equipment specification, commissioning and electrical records, warranties, ownership documents and any network paperwork. Ask the assessor what evidence is needed when the EPC is updated. An invoice that merely says “solar panels” may not describe the installed system adequately.

Croxley Green Solar introduces enquiries to partner installers. Your chosen installer provides its contract and work; it does not replace the assessor or legal adviser needed for your compliance decision.
