Is It Possible for a Business to Install Solar Panels on a Rented Commercial Property?

Renting a commercial property doesn’t necessarily prevent your business from installing solar panels. Many tenant-occupied buildings can accommodate a viable commercial rooftop solar installation, but both the tenant and property owner need to be considered. The project must work for the business whilst also protecting the landlord’s interests.

This will usually involve checking the lease, getting the landlord’s written consent and agreeing responsibility for the cost, ownership, insurance, maintenance and eventual removal or transfer of the system. Planning status doesn’t replace landlord consent, so permission may still be needed from the landlord, freeholder or management company even where permitted development rules apply.

Simply asking your landlord if you can put panels on the roof is not enough. They’ll need a clear picture of the proposed work, the risks and benefits, and what happens to the system at the end of the lease. At the same time, you need reliable figures to determine whether the project is worth taking forward.

So yes, in many cases a business tenant can install solar panels on rented commercial premises. But before work starts, the lease must be reviewed, the landlord’s written consent must be obtained and the legal, financial and practical responsibilities need to be agreed by both parties.

This guide provides general information, not legal advice. The lease-law references relate to England and Wales. The planning guidance relates to England, while the grid-connection and export-scheme references cover Great Britain. Take advice for the property and UK nation concerned.

Review the lease before designing the solar installation

Before a system is designed in detail, a commercial property solicitor should establish what rights you already have and what the landlord will need to approve. Occupying the building doesn’t necessarily give you control of its roof – the roof structure, roof covering and airspace may be retained by the landlord, particularly in a multi-let property.

The lease review should answer a few practical questions:

– Is the roof included within the premises let to your business?

– Are external or structural alterations prohibited, or permitted with consent?

– Do you have rights to access the roof, electrical intake room and cable routes?

– Who is responsible for roof repair, replacement and existing warranties?

– Can a funder, installer or maintenance contractor be given access rights?

– What does the lease say about reinstatement and dilapidations?

– Could the installation affect rent review, service charges, assignment or a break clause?

– Is there enough time left on the lease for the proposed funding and ownership model?

That last question can change the whole structure of the project. A tenant-funded system might be workable where the business has a long, secure term and expects to remain in occupation. With only a few years left, landlord ownership, an agreed transfer or a different funding arrangement usually makes more sense.

The Better Buildings Partnership’s Green Lease Toolkit makes the same underlying point – on-site renewables need to be considered alongside the physical constraints of the building, lease length, property rights, electricity procurement, roof access and the lease’s alteration provisions.

Landlord consent must address more than the installation

A positive conversation with the landlord is useful, but an informal “yes” isn’t enough for equipment that will be fixed to a commercial building and connected to its electrical infrastructure.

The lease may require the work to be documented through a licence to alter. Depending on the property and funding structure, the parties may also need a deed of variation, a roof lease or licence, a direct agreement, a power purchase agreement, or consent from a superior landlord or lender. The right document depends on the lease and the commercial arrangement, so it should be settled by the parties’ legal advisers before installation begins. The Better Buildings Partnership also advises that property rights, access, maintenance and arrangements that bind future owners or occupiers should be addressed through appropriate lease drafting.

The formal agreement should make the practical position unambiguous. It will normally need to cover the approved design, installation method, roof access, working hours, maintenance, monitoring, insurance, liability for damage, temporary removal for roof repairs, equipment ownership, export income and the position when the tenancy ends.

Without that clarity, a project that looks straightforward on installation day can become a problem when the roof needs replacing, the building is sold or the tenant decides to move.

Does a landlord have to agree to commercial solar panels?

No. A tenant doesn’t have an automatic right to install solar simply because the project appears beneficial.

In England and Wales, section 19(2) of the Landlord and Tenant Act 1927 says that where a lease restricts the making of improvements without the landlord’s licence or consent, that consent isn’t to be unreasonably withheld. The same provision allows a landlord to seek reasonable sums for damage or loss in value, properly incurred legal or other expenses, and in some circumstances an undertaking to reinstate the premises. Whether it applies to a particular solar scheme depends on the wording of the lease, the nature of the works and whether they’re legally treated as an improvement. Section 19 doesn’t apply to agricultural holdings covered by the Agricultural Holdings Act, or to farm business tenancies, so agricultural occupiers need specific advice.

A landlord may have legitimate concerns where:

– The roof is approaching the end of its serviceable life

– The proposal could affect a roof warranty or the building’s insurance

– Structural capacity or fire-safety questions haven’t been resolved

– The landlord is considering refurbishment, extension or redevelopment

– A lender, superior landlord or insurer hasn’t agreed

– A third-party solar agreement would run beyond the tenant’s lease

– Responsibility for maintenance, roof damage, removal or reinstatement is unclear

– The building is multi-let and access, metering or electricity allocation is complicated

Those concerns don’t make the project impossible. They show what the proposal needs to resolve. The best route to consent is to reduce uncertainty before asking the landlord to make a final decision.

How should solar ownership and funding me structured

There’s no single model that suits every rented property. The right answer depends on the remaining lease term, available capital, energy use, landlord objectives and the return produced by each funding option.

The Better Buildings Partnership advises that PPAs are bespoke, sophisticated agreements and that the parties should take appropriate advice before entering into one. It also identifies lease length, property interests, electricity procurement and roof access as relevant to the choice of arrangement.

Paying for a system outright will often deliver the strongest long-term return, while commercial solar finance can protect cash flow and a PPA can remove the upfront capital requirement. Each option changes the total cost, the contractual commitment and the value retained by the tenant. It should be modelled against the site’s actual energy use and the lease timetable, rather than selected on headline price alone.

Show your landlord why the project is worth supporting

A tenant’s lower electricity bill may be the main commercial driver, but it isn’t a complete landlord case. The proposal becomes stronger when it shows how the building owner is protected and where the property might benefit.

– Energy performance and future readiness. Solar may contribute to a better EPC rating, although the effect has to be assessed for the individual building and should never be assumed. Privately rented non-domestic properties covered by the Minimum Energy Efficiency Standards in England and Wales currently need an EPC rating of at least E unless a valid exemption applies. In June 2026, the Government confirmed its intention to require privately rented non-domestic buildings over 1,000 square metres to reach EPC B from 2031 where cost-effective. That proposal still requires secondary legislation before it becomes law.

– A more useful proposition for future occupiers. On-site generation and the possibility of lower energy costs may make a property more attractive to businesses with high daytime consumption, procurement requirements or carbon-reduction targets. It’s safer to describe that as a potential marketability benefit than to promise an increase in capital value.

– A possible return or long-term asset. Depending on the structure, the landlord may own the system, receive an agreed payment, benefit from electricity sales or take ownership at a defined point.

– Tenant retention. A business that has secured lower operating costs and invested time in a well-structured energy project may have a stronger reason to remain in the premises. That isn’t guaranteed, but it can form part of the commercial discussion.

A credible proposal should also acknowledge the disadvantages. Roof access, future repairs, legal costs, lender requirements, insurance, redevelopment plans and end-of-lease responsibilities all need to be dealt with. Treating those issues seriously will do more to build trust than trying to convince the landlord there’s no risk.

Landlord consent is one part of a wider approvals process

Even after the landlord agrees in principle, the project still needs the appropriate technical and statutory checks.

Planning and building control

Rooftop solar on a non-domestic building in England may qualify as permitted development, but limits and conditions apply. Some installations require the local planning authority’s prior approval, and different restrictions apply to listed buildings, scheduled monuments and other sensitive sites. The Planning Portal also makes clear that leaseholder permission is separate from the planning position.

Building regulations will normally apply. The existing roof must be checked to show that it can carry the additional load, and the electrical work has to comply. A roof condition survey may also be needed, to avoid installing a long-life system over a roof that’s likely to need major work much sooner.

Electricity network connection

The installer must follow the relevant Distribution Network Operator connection process. Energy Networks Association guidance identifies G98 for generators below the 3.68 kW per-phase threshold, and G99 for larger connections. Most commercial systems exceed the G98 limit, so the network application should be considered early rather than left until the installation programme is fixed.

Property and project due diligence

The exact list will vary, but a commercial rooftop project may also need confirmation of:

– Structural capacity and roof condition

– The effect on any roof guarantee

– Fire strategy and safe system design

– Asbestos information where relevant

– Building-insurer requirements

– Lender, superior landlord or management-company consent

– Cable routes, meter arrangements and plant locations

– Safe access for installation and future maintenance

These checks protect both parties. They also help prevent a landlord from being asked to approve a design that later has to be reworked.

Make it easy for your landlord to assess the project

A landlord doesn’t need a sales brochure. They need enough information to judge the commercial value, the effect on the building and how easily the arrangement can be managed or reversed.

A useful landlord approval pack should include:

– A one-page project summary. Explain what’s proposed, why the business is considering it, who might fund it, and what decision is being requested now.

– A solar feasibility analysis. Use actual energy and tariff data to show indicative system size, expected generation, likely on-site use, export, costs, funding routes and projected return.

– An indicative layout and roof plan. Show where the equipment, cable routes and access points are likely to sit, while making clear that detailed design follows surveys and consent.

– A responsibility schedule. Set out the proposed position on ownership, maintenance, monitoring, insurance, damage, roof works, export income and professional costs.

– An approvals plan. Identify the expected planning, building-control, DNO, insurer, lender and legal steps.

– An installation and access plan. Explain likely working hours, scaffolding, disruption, health and safety arrangements, and how the tenant’s operations will be protected.

– An end-of-lease proposal. State whether the system would be removed, transferred, bought out or assigned to a future occupier.

The first request should usually be for in-principle consent to investigate the project properly – not final approval of an unfinished design. That gives the landlord a controlled decision and avoids either party spending heavily before the basic property position is known.

The lease may also allow the landlord to recover reasonable legal, surveyor or other professional costs connected with considering consent. Raising that point openly is more constructive than allowing it to appear as an unexpected obstacle later.

Agree what happens at the end of the lease before installation

A commercial solar system is intended to operate for far longer than many business leases. We treat commercial solar as long-term infrastructure – component and design decisions that will affect performance over decades – which means the exit arrangement needs the same attention as the installation itself.

The parties could agree that the tenant will remove the system and reinstate the roof, that ownership will transfer to the landlord, that the landlord can buy the equipment at an agreed value, or that the arrangement can be assigned to the next occupier. A funded system may also have an early-termination or buyout mechanism.

None of these options is automatically right. What matters is that the route is written down before either party commits – not left for a dilapidations discussion years later.

Build a case with evidence before approaching your landlord

For a tenant, there’s little value in negotiating complex roof rights for a project that doesn’t make financial sense. There’s equally little value in producing a strong solar model that can’t work with the lease or the landlord’s plans for the building.

At Power Different we start with the numbers. Across our commercial solar projects, the same principle applies – establish what the site actually uses and pays for, before designing the solution. Our free solar feasibility analysis uses actual energy usage, tariff information, site potential and funding options to show what solar could realistically deliver, including expected generation, likely savings and whether battery storage or export improves the case. If the figures don’t stack up, our team will say so before the business commits to design and installation.

What we do isn’t a substitute for your solicitor’s lease advice. It gives you the technical and financial evidence needed to decide whether the landlord conversation is worth having – and to make that conversation more useful when it happens.

Find out whether solar could work at your rented premises

Before asking your landlord to approve a long-term change to the building, establish whether the project works for your business.

Request a free, no-obligation solar feasibility analysis based on your actual energy data. You’ll get a clearer view of the likely system, performance, costs, funding routes and return – so you can approach the landlord with evidence rather than an estimate.

Frequently asked questions about solar installations on rented commercial property

Can I install commercial solar panels without my landlord’s permission?

You shouldn’t assume so. Check the lease before carrying out physical surveys, granting access rights or instructing installation work. A tenant-led rooftop project will commonly need the landlord’s written consent, and may require a licence to alter or another formal agreement.

Does permitted development mean landlord consent is unnecessary?

No. Planning status and property rights are separate. A project may fall within permitted development rules and still require permission from the landlord, freeholder or management company.

Can a landlord refuse permission for solar panels?

Yes, depending on the lease and the proposed works. In England and Wales, consent to improvements may not be unreasonably withheld where section 19(2) of the Landlord and Tenant Act 1927 applies – but that isn’t an automatic right to install. Take advice on the lease and the specific proposal. Agricultural holdings and farm business tenancies require separate consideration because section 19 doesn’t apply to them.

Is solar worthwhile if only a few years remain on the lease?

It can be, but the structure becomes particularly important. The figures may work if the landlord funds or takes ownership of the system, if the parties agree a transfer, or if a funded arrangement can accommodate the lease term. Model the options before entering long-term commitments.

Who owns solar panels installed by a commercial tenant?

Ownership depends on the contract and property documents. It could sit with the tenant, landlord or a third-party funder. The agreement should also cover fixtures, maintenance, export income, transfer and removal at the end of the lease.

Will rooftop solar increase business rates?

In England, eligible plant and machinery used for on-site renewable energy generation and storage is currently exempt from business rates until 31 March 2035. The treatment of the specific project, the parties and the relevant UK nation should still be confirmed with a rating or tax adviser.
