Heat pump radiators for Westerham homes
Homes around Westerham range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
In Westerham, bay-windowed front rooms are often the rooms that need a larger radiator when moving to a heat pump. Radiator fitting in Westerham is scheduled with your heat pump installation so the system is drained only once.
We size each radiator to your room-by-room heat loss so a heat pump can heat your home at a low, efficient flow temperature.
- Homeowners who want the lowest practical flow temperature for efficiency
- Rooms with little wall space, where a fan-assisted radiator fits better
- Rooms that already feel slow to heat, such as bay-windowed living rooms
What's included
- Pipework checks and any agreed pipe upgrades
- A radiator schedule showing which radiators stay, which change and their outputs
- Making good around brackets and pipe routes, with any decorating agreed in your quote
- Balancing every radiator so each room heats evenly
- Supply and fitting of new radiators, valves and brackets
Many older houses in Westerham still have their original single-panel radiators, so the survey checks each one against the room it heats.
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 Westerham 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.
Guide prices for heat pump radiator upgrades in Westerham
These are guide prices for Kent, installed and including VAT. Your final price is fixed in a written quote after the survey and depends on the heat loss of the house, the radiators that need changing and where the unit goes.
| Work | Guide price |
|---|---|
| Replacement radiator, sized for a heat pump (each, fitted) | £260–£460 |
| Upgrade of about 10 radiators | £2,050–£5,150 |
| Pipework upgrade (e.g. microbore to larger bore) | £1,550–£3,600 |
Installed, inc VAT. The survey lists which radiators need changing.
Designing for Westerham's winters
Westerham 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.
What happens after you enquire in Westerham?
- Tell us about your home: postcode, property type and current heating.
- We book a survey in Westerham; 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.
Heat pump radiator upgrades in Westerham: questions
Where would the outdoor unit go on a Westerham house?
Usually at the side or rear, on a level base with space around it for airflow and servicing, away from bedroom windows where possible. The surveyor checks positions at your Westerham home.
Do you cover Sevenoaks as well as Westerham?
Yes. We arrange surveys and installation in Sevenoaks, which is about 5 miles east of Westerham, and across Kent.
How soon can you survey a home in Westerham?
Survey dates depend on how busy installers are in Kent. We offer the next available dates when you enquire and confirm them in writing.
How much does a heat pump radiator cost?
A replacement radiator sized for a heat pump has a guide price of £250–£450 each, installed and including VAT. Upgrading about ten radiators in a typical home has a guide price of £2,000–£5,000. The final price is fixed in your written quote after the survey, once the radiator schedule shows exactly which radiators change.
Do I need new radiators for a heat pump?
Not necessarily: many homes keep most of their radiators and replace only a few. The heat loss survey checks each room against its existing radiator at the planned flow temperature. Rooms with large windows, high ceilings or extensions are the usual candidates for an upgrade, while bedrooms often need no change. Your radiator schedule lists every decision.
