A heat pump for a let property is a full air source heating and hot water system designed around how tenants use the home, with installation, handover and servicing planned to suit both landlord and tenant. Landlords follow the same survey and design process as owner-occupiers, and in England and Wales they can use the Boiler Upgrade Scheme for their let homes.
Shared houses in Cornwall usually need larger hot water storage to cope with busy mornings. For tenanted homes in Cornwall, installation dates and access are agreed in writing before work starts. Landlords in Cornwall can arrange annual servicing around tenancy changes and inspection visits.
Who it suits
- Properties between tenancies, when access and disruption are easier to manage
- HMOs with high hot water demand that need careful cylinder sizing
- Landlords in England and Wales replacing gas, oil or electric heating in let homes
- Landlords who want to remove gas appliances from a property
Grants and rules for heat pumps in England
In England the Boiler Upgrade Scheme gives £7,500 towards an air source heat pump (£9,000 if it replaces oil or LPG, from 21 July 2026 to 31 March 2027), and since 28 April 2026 a valid EPC is no longer needed. The grant is applied for by the MCS-certified installer and shown as a deduction on your quote.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Since 29 May 2025, permitted development in England allows up to two air source heat pumps on a house, each up to 1.5 m³, with no blanket 1 m boundary rule — the installation must still meet the MCS planning standards, including the noise check. Listed buildings, flats and some conservation-area positions need extra consent, which we check at survey.

Landlords and let properties questions
Do tenants need training to use a heat pump?
Not training, but a clear explanation helps. Heat pumps are designed to run steadily, with radiators feeling warm rather than hot, so tenants used to boilers may be tempted to switch them off. We provide a handover sheet written for tenants covering the controls, hot water times, what to do if an error appears and why the unit should stay on.
How much does a heat pump cost for a rental property?
A full air-to-water system for a typical 3 bedroom home has an installed guide price of £12,000–£15,500, including VAT, or £4,500–£8,000 after the standard Boiler Upgrade Scheme grant in England and Wales. Flats and small terraces typically sit at £9,500–£12,500. Your written quote fixes the price after the survey.
Will a heat pump improve my property's EPC rating?
It can, but the effect varies. EPC ratings depend on insulation, glazing, the heating system and how the assessment is modelled, so a heat pump in a poorly insulated home may change the rating less than expected. Check the current letting standards for your nation, and ask an EPC assessor to model the change if the rating matters for your plans.
Can a heat pump go on a block of flats or an HMO?
Often, yes, but it needs more planning. In flats, the outdoor unit position and pipe routes usually need freeholder or management company consent, and some positions need planning permission depending on the nation, which we check at survey. In HMOs, hot water demand is higher, so cylinder sizing is critical. Larger buildings may suit a commercial design instead.
