Air source heat pump installation in Oxted: what to expect
Most homes can run on a heat pump if the system is designed properly, and Oxted is no different. The key is matching the heat pump and radiators to the home's heat loss.
Installers working in Oxted plan the order of work so heating and hot water are off for as short a time as practical. Homeowners across Surrey can arrange a survey in Oxted for a room-by-room design and a written quote before committing to anything.
We survey your home, design a heat pump system around its real heat loss, and manage the installation from the first visit to the MCS certificate.
- Houses with reasonable insulation, or a plan to improve it
- Owners who want one contract covering design, fitting and paperwork
- Owners and landlords in England and Wales eligible for the Boiler Upgrade Scheme
What's included
- MCS registration and certificate, plus network operator notification
- Commissioning, handover and a walk-through of the controls
- Boiler Upgrade Scheme application in England and Wales where eligible
- System design, unit sizing and a written quote
- Outdoor unit, hot water cylinder and weather compensation controls
For older properties in Oxted, the heat loss calculation looks closely at solid walls, single glazing and draughts before any unit is sized.
Grants and rules for heat pumps in England
Homes in Oxted 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.
Air source heat pump installation costs around Oxted
The ranges below are typical installed prices for homes in Surrey, including VAT. A survey sets the exact figure, because two similar-looking houses in Oxted can need quite different radiators and pipework.

Installed, inc VAT: unit, cylinder, controls, minor pipework and commissioning.
Designing for Oxted's winters
Oxted 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.
The steps for air source heat pump installation in Oxted
- Tell us about your home: postcode, property type and current heating.
- We book a survey in Oxted; the surveyor measures rooms, windows and radiators and looks at cylinder space.
- The design and quote arrive in writing, including radiator changes and the outdoor unit position.
- 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 source heat pump installation in Oxted: questions
Can you service a heat pump in Oxted that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Oxted, whoever fitted them. Tell us the make and model when you book.
What size heat pump does an Oxted 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 Oxted home.
Do you cover Westerham as well as Oxted?
Yes. We arrange surveys and installation in Westerham, which is about 3 miles east of Oxted, and across Surrey.
Will an air source heat pump be noisy?
Heat pumps are designed to run quietly, but where the unit sits makes a real difference. The survey looks for a position away from bedroom windows and neighbours, with clear airflow, and the installation must pass the MCS noise assessment. The fan is most noticeable on very cold days when the unit works hardest, and a little vapour during the periodic defrost is normal.
Do I need new radiators for a heat pump?
Not always; many homes keep most of their radiators and change only a few. Because a heat pump runs at a lower water temperature than a boiler, each radiator gives out less heat, so the survey checks every room against its heat loss. Rooms where the existing radiator falls short get a larger one, with a guide price of £250–£450 each, installed and including VAT.
