What to know about heat pump radiator upgrades in Sandwich
Most homes can run on a heat pump if the system is designed properly, and Sandwich is no different. The key is matching the heat pump and radiators to the home's heat loss.
In Sandwich, bay-windowed front rooms are often the rooms that need a larger radiator when moving to a heat pump. Radiator fitting in Sandwich 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.
- Rooms with little wall space, where a fan-assisted radiator fits better
- Homeowners who want the lowest practical flow temperature for efficiency
- Rooms that already feel slow to heat, such as bay-windowed living rooms
What's included
- Draining, refilling, cleaning and inhibitor treatment of the heating system
- Balancing every radiator so each room heats evenly
- Pipework checks and any agreed pipe upgrades
- Room-by-room heat loss figures for every heated room
- Supply and fitting of new radiators, valves and brackets
Extensions and kitchen-diners around Sandwich with large glazed areas get their own radiator calculation.
Grants and rules for heat pumps in England
Homes in Sandwich 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.
Heat pump radiators prices in Sandwich
Guide prices for Sandwich and the rest of Kent are shown below, installed and inc VAT. We publish ranges rather than a single figure because design details move the price, and the written quote after survey fixes it.

| Upgrade of about 10 radiators | £2,050–£5,150 |

Installed, inc VAT. The survey lists which radiators need changing.
Designing for Sandwich's winters
On the shortest day Sandwich gets about 7 hours 52 minutes of daylight, and the winter sun reaches only around 15° above the horizon at noon. Winters this far south are milder than in most of the UK, which helps a heat pump run at low flow temperatures for much of the season.
What happens after you enquire in Sandwich?
- Tell us about your home: postcode, property type and current heating.
- We book a survey in Sandwich; 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 Sandwich: questions
Can you service a heat pump in Sandwich that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Sandwich, whoever fitted them. Tell us the make and model when you book.
How long does a heat pump survey take in Sandwich?
A home survey in Sandwich usually takes one to two hours. The surveyor measures every heated room, checks windows, walls and radiators, and looks at where the outdoor unit and cylinder can go.
Where would the outdoor unit go on a Sandwich 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 Sandwich home.
Will new radiators be much bigger than my old ones?
Sometimes, but not always. Swapping a single-panel radiator for a double or triple-panel model of the same height and width can raise output substantially, adding only depth from the wall. Where that is not enough, a longer or taller radiator, or a second radiator in the room, may be needed. We agree sizes and positions with you before anything is ordered.
Are fan-assisted radiators noisy?
Fan-assisted radiators make a low, steady fan sound when running at higher output, and many have quieter settings for bedrooms at night. They are useful where wall space is short, such as a kitchen with few clear walls. They need a small electrical supply, which we plan into the installation if you choose them.
