The Landlord's Roof, the Tenant's Meter: Making Renewable Upgrades Work in Rented Homes

Few energy upgrades suit the private rented sector less well than the ones that pay back slowly. A solar array, a home battery or an air source heat pump is a twenty-year asset fixed to a building whose occupants may change every two or three years. The landlord signs the cheque; the tenant reads the meter. Until that mismatch is addressed explicitly, the sector will keep installing far less than the country's decarbonisation targets assume.

The shape of the problem

Around 4.6 million households in England rent privately. The tenure is characterised by short fixed terms, periodic rollovers and a landlord who is often an individual with one or two properties rather than an institutional fund with a sustainability mandate. For that landlord, a rooftop PV system costing several thousand pounds delivers a modest improvement in EPC rating, some protection against future minimum-standard rules, and a marginal uplift in saleability. The electricity bill it displaces belongs to somebody else.

The tenant, for their part, cannot commission structural work, has no incentive to accept weeks of scaffolding and disruption, and has no claim on an asset they will never own. Both parties can behave perfectly rationally and still arrive at the wrong outcome. Economists describe this as a split incentive; landlords describe it as a reason to do nothing.

Metering is where good intentions stall

The practical difficulty arrives as soon as you ask who is named on the electricity account. Under the Smart Export Guarantee, payments for exported electricity are made to the account holder at the metered supply point. If the tenant holds the account, the tenant receives the export income even where the landlord owns the panels. If the landlord holds the account and includes electricity within the rent, the landlord captures both the generation savings and the export payments — but also absorbs the risk of a tenant who runs the immersion heater through the winter.

A third route exists: the landlord installs the array, retains ownership of the generation, and sells power to the tenant at a discount to the retail rate. That is legally workable, but only within Ofgem's maximum resale price rules, which cap what a landlord may charge for electricity at the rate they themselves pay. Anything above that begins to look like unlicensed supply. Any landlord considering a private-wire arrangement should take advice before marketing it as a benefit.

Check meters and sub-metering can apportion consumption where a single supply serves multiple dwellings, but they add cost and complexity. For a single-household let, the simpler answer is usually to decide up front who holds the account and to write the answer into the tenancy.

Consent, access and the tenant's quiet veto

A landlord cannot simply install. The tenancy agreement governs, and the tenant's right to quiet enjoyment is not a formality. Installation requires access, scaffolding, and usually a day or more of disruption; a heat pump retrofit can stretch to a week or more once radiator replacements and pipework are counted. Access for repairs may be taken on twenty-four hours' written notice under the Landlord and Tenant Act 1985, but new installation is a different matter and should be agreed in writing.

Where the property is occupied, the sensible sequence is a written schedule signed before work begins: what is being installed, who owns it, who maintains it, who insures it, what happens to the monitoring app and the warranties if the tenancy ends, and how the roof is made good if the equipment is removed. Renters who expect to stay for years will usually welcome the work. Those on six-month terms will not, and no amount of grant funding changes that.

Minimum standards are the only reliable lever

Voluntary enthusiasm has not delivered. What has moved the sector, slowly, is regulation. Private rented homes have been required to hold EPC band E since 2020, and the government has set out its intention to raise the minimum to band C by 2030, subject to final regulations. A landlord facing a compulsory upgrade has a reason to act that has nothing to do with bill savings — and that changes the negotiating position entirely.

The Boiler Upgrade Scheme grant of £7,500 for air source heat pumps is payable to the property owner, which means a landlord can claim it. It does not, however, resolve the split incentive: the landlord still funds the difference and the tenant still enjoys the lower running costs. Energy Company Obligation funding is available to landlords only in limited circumstances, generally where the property is at the lower end of the EPC scale and the tenant consents.

Four structures that can work

Rent-adjusted installation. The landlord funds the hardware and raises the rent by a documented amount that reflects the improved EPC rating rather than a speculative savings figure. The tenant gains a warmer, cheaper-to-run home; the landlord recovers the capital over a defined period. Rent increases on periodic tenancies must follow the statutory procedure and can generally be made once a year, so the timing needs planning.

Bills-included with a fair-use cap. Common in shared houses and HMOs. The landlord keeps the account, benefits directly from generation and export, and accepts a defined level of consumption risk. A cap written into the agreement protects both sides.

Tenant contribution with a break clause. The tenant pays part of the capital cost in exchange for a lower rent or a fixed energy charge, with a mechanism to recover the unamortised balance if they leave early. Workable, but rarely attractive without an unusually long tenancy.

A green lease with data sharing. The landlord installs, the tenant receives access to the monitoring platform and a share of the export income, and both parties agree maintenance obligations and a handover protocol. This is the arrangement most likely to survive a change of tenant, because the obligations sit with the property rather than the person.

The heat pump complication

Heat pumps deserve separate mention because they are the least divisible of the upgrades. A PV array can be added to a roof with minimal internal disruption; a heat pump usually requires radiator upsizing, pipework alterations, and a cylinder where none existed. In an occupied home, that is a negotiation as much as an installation. Landlords pursuing band C by 2030 will find that fabric measures — loft insulation, cavity fill, draught-proofing — often deliver the EPC uplift more cheaply and with less disruption, with the heat pump following once the building is ready for it.

A short checklist before signing anything

Confirm who holds the electricity account and therefore who receives export payments. Decide who owns the asset and record it in the tenancy. Agree an access protocol and a reinstatement clause. Notify the insurer. Register warranties in the property's name rather than the occupant's. Provide the tenant with the EPC and the commissioning certificate. And be honest about the payback period — a rented-sector retrofit that only works on optimistic assumptions will not be repeated.

The split incentive is not a law of physics. It is a contract term waiting to be written.
