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 South Glamorgan usually need larger hot water storage to cope with busy mornings. Landlords in South Glamorgan can arrange annual servicing around tenancy changes and inspection visits. For tenanted homes in South Glamorgan, installation dates and access are agreed in writing before work starts.
Who it suits
- Landlords who want to remove gas appliances from a property
- Portfolio landlords planning upgrades across several properties
- Landlords in England and Wales replacing gas, oil or electric heating in let homes
- HMOs with high hot water demand that need careful cylinder sizing
Grants and rules for heat pumps in Wales
Homes in South Glamorgan can use the Boiler Upgrade Scheme, which applies in Wales as well as England: £7,500 towards an air source heat pump, or £9,000 when it replaces oil or LPG heating for installations from 21 July 2026 to 31 March 2027. The MCS-certified installer named in your quote applies and deducts the grant.
There is no VAT on installing a heat pump anywhere in the UK, Wales included, until 31 March 2027. Planning rules for heat pumps in Wales are set by the Welsh Government and differ from England's, so the surveyor checks the unit position against them.

Landlords and let properties questions
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.
Can I install a heat pump while tenants are living in the property?
Yes. Most installations typically take 2–4 days on site, with heating and hot water off for part of that time. We agree dates and access with you, provide written details to pass to tenants, and plan the changeover to keep downtime short. Preparing the outdoor unit and cylinder first shortens the period without heating.
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.
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.
