Solar panels can be worth investigating for a rental property, but start by separating three things: the landlord's installation cost, the tenant's electricity savings and any export income. They can belong to different people. Adding them together as though they all repay your investment gives a misleading result.
This landlord solar panels guide uses an existing single let in England as its working example. The Smart Export Guarantee covers eligible installations in Great Britain; the Warm Homes: Local Grant discussed below is England-only. For another nation, a block of flats or an installation owned by someone else, check the relevant arrangements before using the example.
Decide whose problem the installation solves
Begin with a short project note. Are you considering solar because a tenant has asked about electricity bills, because the roof is already being worked on, or because you want to assess a longer-term improvement? Those starting points lead to different decisions about timing, budget and disruption.
Record the current position before requesting quotations: who owns the roof and equipment, who holds the electricity account, who manages the property and what the tenancy says about supplied equipment. Leave uncertain answers open. A letting agent's assumption is not a substitute for a document or a supplier's confirmation.
Use this allocation sheet as a conversation starter, then replace each provisional entry with the arrangement actually agreed for your property.
| Item | Person to identify | Evidence to obtain |
|---|---|---|
| Installation and associated building work | Person paying each invoice | Itemised quotation and approval |
| Electricity used inside the home | Occupier or account holder receiving the benefit | Explanation of how generation interacts with the supply |
| Electricity exported | Eligible generator and named payment recipient | Export supplier's accepted application and tariff terms |
| Servicing, repairs and replacement | Person arranging and funding each task | Contract, warranty and maintenance responsibilities |
| Monitoring and account administration | Person able to see faults and resolve queries | Agreed contact and appropriate account access |
The sheet is a practical planning aid. It does not establish ownership, transfer rights or determine anyone's legal liability.
Check the property before accepting a quote
Ask the installer to explain what their survey covers and what remains for you to arrange. Put roof condition, usable area, shading, equipment location, cabling and access on that discussion list. Request the proposed system's expected generation and the assumptions behind it, rather than relying on a headline savings figure.
Resolve relevant permissions before committing. Depending on the property, that may mean checking a lease or roof rights, lender and insurer requirements, planning restrictions and electricity-network requirements. Ask the appropriate organisation or adviser to confirm the position for the actual proposal. This guide does not say that every installation needs the same permission or that all rooftop panels are automatically permitted.
For an occupied home, agree the proposed visit, disruption and communication arrangements with the tenant. Do not treat permission to inspect for repairs as blanket authority to carry out an improvement. Keep any unresolved access question separate from whether the equipment is technically suitable.
The GOV.UK repairs guide identifies existing landlord responsibilities including the structure, exterior and electrical wiring. Planning a solar project does not remove those responsibilities. Ask the contractor to distinguish necessary repair work from the proposed installation in the quotation and completion records.
Compare quotations on the same basis
A cheaper total is difficult to assess if one quotation includes scaffolding and another excludes it. Give each installer the same property information and ask them to itemise the same scope. Avoid comparing an equipment-only illustration with a complete installed proposal.
Build a comparison with these headings:
- proposed equipment, capacity and any optional battery;
- survey findings, generation assumptions and identified limitations;
- building work, scaffolding, electrical work and reinstatement included;
- exclusions, provisional sums and responsibility for unexpected work;
- certification, network paperwork and export-meter arrangements;
- equipment warranties, workmanship cover and the process for raising faults;
- monitoring, servicing expectations and replacement assumptions;
- completion documents, payment stages and cancellation terms.
Ask what happens if the installer stops trading, a component fails or the roof later needs work. Record the answer alongside the relevant warranty wording. A reassuring sales email should not silently replace the contract you are being asked to sign.
Keep finance costs separate from the installation price. If borrowing is involved, obtain the actual finance terms and suitable advice where needed; this guide does not recommend a product or forecast investment returns.
Check export payments and grant funding separately
Under the Smart Export Guarantee, participating suppliers pay qualifying small generators for electricity exported to the grid. Ofgem identifies solar PV as an eligible technology, subject to the scheme's criteria. Installations must be in Great Britain.
The supplier sets its tariff rate, contract length and other terms. Ofgem says rates must be above zero and payments use export-meter readings. Ask the prospective supplier to confirm eligibility, metering and the correct applicant and payment recipient for your arrangement. Do not assume the landlord automatically receives the money because they paid for the panels. Compare current offers before choosing.
The Warm Homes: Local Grant has a different purpose and application route. In England, eligible privately owned homes with EPC ratings D to G may receive council-arranged improvements, potentially including solar. Household eligibility, available council funding and a survey matter; a landlord may need to contribute. Ask the council about the particular home before relying on support.
Keep any unconfirmed grant outside your committed budget. Likewise, an export tariff is not a grant towards installation. Retain written decisions and conditions rather than marking an application as funding received.
Work through a fictional landlord cash-flow example
Suppose a landlord pays £6,000 for an installation. Assume, solely for this example, that the confirmed arrangement pays the landlord £300 a year in export receipts and they set aside £100 a year for future equipment costs. The tenant's estimated electricity saving is separately assumed to be £350 a year.
| Illustrative entry | Landlord calculation | Treatment |
|---|---|---|
| Initial installation outlay | £6,000 | Paid at the start |
| Annual export receipts | £300 | Assumed landlord receipt |
| Annual equipment reserve | £100 | Money set aside, not necessarily an actual annual bill |
| Annual amount after that reserve | £200 | £300 minus £100 |
| Tenant electricity saving | £350 | Excluded from landlord receipts |
Dividing £6,000 by £200 gives 30 years. That is a simple illustration under fixed assumptions, not a forecast or a complete payback calculation. It ignores financing, tax, tariff changes, changing generation, inflation and the timing and amount of actual repairs or replacements. A reserve is a budgeting choice; it does not guarantee enough money will be available.
Now reduce assumed export receipts to £200. After the same £100 reserve, only £100 remains each year, and the same division gives 60 years. Neither scenario demonstrates that the installation is suitable. The exercise shows why a small change in landlord receipts can materially alter a decision.
Do not add the tenant's £350 saving to either landlord figure, assume it supports a rent increase or invent a retention benefit. Use real quotations and confirmed account arrangements for your own assessment. The landlord costs calculator can help organise broader running-cost assumptions; it is not a solar performance model.
Prepare the tenant and property handover
Before completion, assemble the system specification, invoice, relevant permissions, certificates, warranties, operating instructions and contractor contacts. Record equipment identifiers and where isolation and fault instructions can be found. Ask the installer to demonstrate the supplied system and explain which tasks require a competent contractor. Do not ask a tenant to diagnose electrical faults or work at height.
Agree a clear route for reporting a fault and who will contact the installer, supplier or managing agent. Clarify which monitoring information each person can access, without sharing unnecessary personal account details. Record the export arrangement and outstanding applications separately from the ordinary electricity account.
At a tenancy change, review the handover rather than copying the previous tenant's account assumptions. Confirm the appropriate supplier process, documents for the incoming occupier and responsibility for unresolved faults. Keep property-level equipment records distinct from an individual's account information, using the property records checklist.
Finally, give every unresolved question an owner and a follow-up date. Keep the EPC assessment separate: panels do not guarantee a particular rating or settle your letting obligations. Use the existing EPC rules guide for that topic and ask a qualified assessor about the particular property. A useful solar decision ends with clear costs, benefits and responsibilities, even when the decision is to postpone the project.
