Can you rent your commercial roof for solar panels?

Renting your commercial roof can provide host income without buying the solar equipment, but the lease and electricity agreement need separate review. The government's solar roadmap identifies commercial lease barriers in Action 10 [S1]. Compare rent with the return from owning generation, and confirm roof repairs, access and exit costs before signing. Checked October 2026.

How does renting your roof for solar panels work?

You offer roof space and access rights. Another party funds and owns the solar PV, meaning photovoltaic, equipment. Your proposed contract might pay rent, offer electricity under a power purchase agreement, or combine the two. Ask for each benefit separately so that rent is not confused with a reduction in your electricity bill. BRE’s commercial solar guide discusses arrangements where the building owner and equipment owner differ. [S2]

The government’s solar roadmap recognises that traditional commercial leases can obstruct rooftop solar. That is a reason to investigate your property’s rights early. A large roof does not settle who can authorise work, who buys the electricity or who must pay to remove panels for repairs. [S1]

Read PPAs versus buying solar alongside any rent proposal. Treat a roof lease and an electricity purchase commitment as separate decisions, even when they arrive together.

For an education estate, the Department for Education’s England PPA pilot is a specific private-investment route. Its existence does not establish eligibility for another commercial building or set a roof-rent tariff. [S4]

How do fully funded, part funded and self funded compare?

These are comparison models. Your actual ownership and payment terms need written confirmation.

For roof-only rent, you might not buy any solar electricity. For an owner-occupied building, direct consumption may instead be valuable. Compare the alternatives using the same generation and occupancy assumptions, rather than comparing a rent cheque with gross electricity sales. See solar self-consumption and export.

What could your site earn, and how many years until payback?

The following is an illustration, not a quote. All financial, generation and usage inputs are assumptions, not market averages or partner offers. Low, mid and high refer to on-site use of the same assumed generation. Figures exclude VAT, tax, borrowing, inflation, degradation and major equipment replacement.

Annual net value = direct use × £0.25 + exported energy × £0.05 − £1,000. In the mid case this is 60,000 × £0.25 + 30,000 × £0.05 − £1,000 = £15,500. This is mainly avoided electricity expenditure, rather than cash income. Export income is only the export term. No business-rates change is assumed; obtain a site assessment.

For part funded, multiply annual net value by the assumed 50% host share. Simple return on investment, or ROI, is annual net benefit ÷ host capital × 100. Payback is host capital ÷ annual net benefit. The matching returns here arise because both capital and benefit are halved; real offers need not share them proportionately. There is no capital payback calculation for the assumed fully funded host contribution of zero.

Replace these inputs with your survey, bills and contract. Obtain separate costs for roof repairs, network work and any replacement reserve. A PPA with minimum purchase obligations needs a different cash-flow model.

What happens if the roof needs repairs or you sell?

BRE identifies lease duration, repair obligations and alteration rights as commercial solar issues. Its older guide is useful for those questions; do not reuse its historic subsidy references as current funding rules. [S2]

Ask your solicitor to put panel removal, storage, reinstatement and interrupted-generation costs into the agreement. Request a schedule of roof condition before work. Ask how sale, refinancing, tenant departure or redevelopment changes the obligations. Require a priced exit method and identify who carries liability for water ingress, equipment damage and contractor access. These are proposed negotiation points, not statements about what every lease allows. Check legal terms with your solicitor and tax treatment with your accountant.

Does your roof have the right power connection and consents?

Your distribution network operator, or DNO, manages the local electricity network. UK Power Networks separates its network role from the installer’s work and provides commercial solar and storage connection guidance. Ask your installer to confirm the applicable route with your own DNO, including any export limit. [S3]

Request a structural survey, cable route and safe-access plan. Ask your council to confirm the planning position for your building and nation. Keep equipment off parking areas unless the site plan expressly allows for it. Use the roof survey guide to prepare the installer brief.

What should you do next?

Gather your postcode, ownership details, roof condition and electricity profile, then get matched with an installer that covers your area. Request a rent offer and an ownership option with comparable assumptions.
