Most of the practical work is about people. Tenants need notice of the installation days, access to rooms where radiators change and a simple explanation of how to use the controls. We plan the installation in stages where possible, keep the time without heating and hot water as short as practical, and provide handover notes written for tenants.
Flats in East Sussex and across East Sussex need freeholder consent checked early, before the outdoor unit position is fixed. For tenanted homes in East Sussex, installation dates and access are agreed in writing before work starts. Landlords with let homes in East Sussex can have each property surveyed and quoted separately or as a group.
Who it suits
- Portfolio landlords planning upgrades across several properties
- Landlords who want to remove gas appliances from a property
- Properties between tenancies, when access and disruption are easier to manage
- HMOs with high hot water demand that need careful cylinder sizing
Grants and rules for heat pumps in England
Homes in East Sussex can use the Boiler Upgrade Scheme, which takes £7,500 off the cost of an air source heat pump when it replaces fossil-fuel or electric heating. Replacing oil or LPG heating qualifies for £9,000 for installations from 21 July 2026 to 31 March 2027, and air-to-air systems for £2,500. The MCS-certified installer named in your quote applies for the grant and deducts it from the price.
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
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.
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.
