Can a Landlord Recover Solar Costs Through the Service Charge?

The short answer is no — not the capital cost, and not by default. If you are a landlord weighing up a rooftop array on a multi-let building and assuming the service charge will quietly absorb the bill, that assumption fails the moment it meets the RICS standard and the wording of most modern leases. The initial cost of installing new plant is, as a rule, a landlord cost. There are routes that move the economics back in your favour, but the service charge is not the main one, and treating it as such invites a dispute you will lose.

This matters because the service charge is the obvious lever to reach for. You already recover lift maintenance, cleaning, and plant repairs through it. Solar feels like more of the same. It is not, and the distinction turns on one word: improvement.

What the RICS standard actually says

The governing document is the RICS professional statement Service Charges in Commercial Property, 2nd edition, which came into force on 31 December 2025 and applies to most managed commercial property in England and Wales. It is mandatory for RICS members and firms, and the courts treat it as the benchmark for reasonableness even where neither party is RICS-regulated.

Two principles in that standard sink the naive approach.

First, the service charge exists to recover the cost of providing services — the day-to-day operation, maintenance, and repair of the building and its shared parts. It is not a vehicle for funding the landlord’s own capital projects. The standard is explicit that the initial cost of providing new plant or equipment, and improvements over and above the original specification, are not recoverable through the service charge unless the lease expressly allows it and the expenditure is justified.

Second, there is a long-standing line between repair and improvement. Replacing a failed boiler with a like-for-like modern equivalent is usually recoverable. Bolting a brand-new generating asset onto a roof that never had one is an improvement to the landlord’s investment — it raises the value and EPC of an asset the landlord owns and will sell. Most lease service-charge clauses, read properly, do not reach it.

On ESG and sustainability spend specifically, the 2nd edition does open a door, but a narrow one. Costs associated with improving the environmental performance of a building can be recoverable only where they relate to a genuine service that benefits occupiers — for example, the ongoing cost of running and maintaining equipment, or measures that demonstrably reduce occupiers’ energy costs. The capital cost of the kit itself stays with the landlord. Buying a solar array is not a service. Operating and maintaining it might generate a recoverable element, but that is a fraction of the project cost, not the headline.

Why the lease usually closes the door too

Even where a landlord argues the RICS standard permits something, the lease governs. Three drafting realities tend to bite.

• Sweeper clauses don’t sweep this far. A general clause letting the landlord recover the cost of “any other services or works” is read narrowly by the courts. It will not be stretched to fund a capital improvement the parties never contemplated.
• Caps and “fair and reasonable” wording. Many leases cap the service charge or require costs to be fair and reasonable. A six-figure array landing on one year’s account fails both tests on its face.
• The improvement carve-out. Well-drafted leases expressly exclude improvements and the initial cost of new plant from the recoverable list. That exclusion is fatal to recovering the install.

Push it anyway and you risk a service-charge dispute, a refusal to pay, and — if you are RICS-regulated — a complaint. The downside is poor. So what works.

The routes that actually move the economics

There are three honest mechanisms that put the right cost with the right party. None relies on the service charge carrying the capital.

Route 1 — the landlord–tenant PPA

You own and fund the array. The tenant signs a power purchase agreement and buys the electricity it generates at a fixed unit rate set below their grid price. The tenant pays nothing up front, sees a lower per-kWh cost from day one, and you recover your capital plus a return over the contract term through the unit sales. The economics live in the energy bill, not the service charge, so the RICS objection disappears. This is the cleanest structure for a single-let unit or a building with one dominant daytime occupier. We cover the mechanics, metering, and private-wire considerations in the landlord-tenant PPA guide.

Route 2 — the capped green-lease contribution

This is the structure the Better Buildings Partnership green-lease toolkit promotes for shared landlord works, and it is the fair answer to the split incentive. The landlord funds and installs the array. The tenant then makes a contribution toward the cost — but the contribution is capped at the tenant’s verified energy saving, so they are never asked to pay more than the measure puts back in their pocket. The tenant is no worse off; the landlord recovers a meaningful share of capital; and because the payment is tied to a genuine saving rather than dressed up as a service, it survives scrutiny. It is negotiated at lease renewal or regear and written into the green-lease clauses. See the green leases and solar guide for the drafting.

Route 3 — rent

The blunt instrument, and sometimes the right one. Where the array genuinely improves the building — lower running costs, a better EPC, stronger ESG credentials — that value can be reflected in the headline rent on a new letting, or argued at rent review. You are not recovering the cost line-by-line; you are pricing the improved asset. This works best where the solar measurably raises lettability and the comparable evidence supports it.

The principle underneath all three

Every workable route follows the same logic: the party that benefits pays, and the cost sits in the instrument that matches the benefit. Energy saving lives in a PPA or a saving-capped contribution. Asset value lives in the rent. The service charge stays where it belongs — funding the running of the building.

That is the practical resolution of the split incentive, the structural problem at the heart of letting a building you don’t occupy. The landlord holds the capital and the asset; the tenant holds the energy bill and the saving. Force solar through the service charge and you collide with both the lease and the RICS standard. Match each cost to the party that gains and the deal stands up. We set out all five ownership routes through that problem in the split incentive guide.

Before you commit

Two things determine which route fits: your tenancy structure (single-let, dominant-tenant, or genuinely multi-let) and the remaining term, since a PPA or capped contribution needs enough lease length to amortise. Get those wrong and even the right mechanism stalls. Get them right and the array pays for itself without touching a service-charge account that was never built to carry it.
