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.
Landlords in Northamptonshire can arrange annual servicing around tenancy changes and inspection visits. For tenanted homes in Northamptonshire, installation dates and access are agreed in writing before work starts. Terraced rental homes in Northamptonshire often have small yards, so outdoor unit siting is checked carefully at survey.
Who it suits
- 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
- Portfolio landlords planning upgrades across several properties
- 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.
Heat pumps for landlords prices in Northamptonshire
The ranges below are typical installed prices for homes in Northamptonshire, including VAT. A survey sets the exact figure, because two similar-looking houses in Northamptonshire can need quite different radiators and pipework.

Landlords and let properties questions
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 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.
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.
