Before you book: air-to-air heat pumps in Sevenoaks
In Sevenoaks, as anywhere in the UK, the heat pumps that perform well are the ones designed around low flow temperatures and sized from a proper heat loss calculation.
Top-floor rooms in Sevenoaks that overheat in summer gain from the cooling an air-to-air system provides. For terraced homes in Sevenoaks, the outdoor unit can often sit in a rear yard with tidy pipe runs to each room.
An air-to-air heat pump warms rooms directly with air, and can cool them in summer, but it does not heat your hot water.
- Extensions, conservatories and garden rooms
- Flats and apartments with storage or panel heaters
- Rooms that get too hot in summer as well as cold in winter
What's included
- Electrical supply and controls set up for each room
- Commissioning, MCS certificate and the air-to-air grant claim in England and Wales where eligible
- Condensate drains and neat external pipe covers
- Outdoor unit and indoor units for each room
- Free survey covering rooms to heat, unit positions and hot water options
Flats in Sevenoaks on storage or panel heaters can often switch to air-to-air without fitting radiators or pipework.
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 Sevenoaks quote.
There is no VAT on installing a heat pump anywhere in the UK until 31 March 2027. In England most houses can have an air source heat pump under permitted development, provided the unit meets the MCS noise and siting standards; the old 1 m boundary limit was removed on 29 May 2025. We flag listed buildings, flats and sensitive conservation-area positions at survey.
What to budget for air-to-air heat pumps in Sevenoaks
Here are typical prices for air-to-air heat pumps in Kent, installed and including VAT. Use the guide price tool for a figure based on your home, then a survey confirms it in writing.

| Air-to-air heat pump, multi-room 3–4 bedroom home | £4,100–£8,250 |
Installed, inc VAT. Air-to-air systems heat (and can cool) rooms but do not provide hot water. In England and Wales the Boiler Upgrade Scheme gives £2,500 towards an air-to-air system in a home, deducted from your quote where eligible.
Winter daylight and heating in Sevenoaks
Sevenoaks sees roughly 7 hours 52 minutes of daylight in late December against 16 hours 36 minutes in June. Milder southern winters suit heat pumps well, though the system is still sized for a cold snap rather than an average day.
From survey to switch-on in Sevenoaks

- On installation days the old system is removed and the new one fitted and filled.
- We commission the heat pump, show you the controls and register the installation.
Air-to-air heat pumps in Sevenoaks: questions
Do you cover Westerham as well as Sevenoaks?
Yes. We arrange surveys and installation in Westerham, which is about 5 miles west of Sevenoaks, and across Kent.
How soon can you survey a home in Sevenoaks?
Survey dates depend on how busy installers are in Kent. We offer the next available dates when you enquire and confirm them in writing.
What size heat pump does a Sevenoaks home need?
It depends on the heat loss, not the postcode. As a rough guide, a 3 bedroom semi often needs 6–9 kW, but the room-by-room survey sets the actual size for your Sevenoaks home.
Can an air-to-air heat pump heat my water?
No. An air-to-air heat pump heats and cools the air in rooms but does not produce hot water. You need a separate source, such as an existing immersion cylinder, a hot water heat pump or an electric water heater. If you want one system for heating and hot water, an air-to-water heat pump with a cylinder is the alternative.
How do I look after an air-to-air system?
Clean the indoor unit filters regularly, typically every few weeks during heavy use and following the manufacturer's guidance, and keep the outdoor unit clear of leaves and snow. Annual servicing is recommended and is often a condition of the manufacturer's warranty. Any work on the refrigerant circuit must be done by an F-gas certified engineer.
