Heat pump radiators for Kingston upon Thames homes
Every property in Kingston upon Thames is different, so the design starts from measurements rather than a rule of thumb. That keeps the system the right size and the running costs predictable.
In Kingston upon Thames, bay-windowed front rooms are often the rooms that need a larger radiator when moving to a heat pump. We plan radiator upgrades in Kingston upon Thames so floorboards are lifted only where pipework genuinely needs changing.
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.
- Extensions and loft conversions with large areas of glazing
- Homes switching from a gas, oil or LPG boiler to a heat pump
- Homeowners who want the lowest practical flow temperature for efficiency
What's included
- Draining, refilling, cleaning and inhibitor treatment of the heating system
- Supply and fitting of new radiators, valves and brackets
- Making good around brackets and pipe routes, with any decorating agreed in your quote
- Balancing every radiator so each room heats evenly
- A radiator schedule showing which radiators stay, which change and their outputs
Radiator fitting in Kingston upon Thames is scheduled with your heat pump installation so the system is drained only once.
Grants and rules for heat pumps in England
Homes in Kingston upon Thames 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.

Winter daylight and heating in Kingston upon Thames
On the shortest day Kingston upon Thames gets about 7 hours 50 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.

Heat pump radiator upgrades in Kingston upon Thames: questions
Can you service a heat pump in Kingston upon Thames that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Kingston upon Thames, whoever fitted them. Tell us the make and model when you book.
What size heat pump does a Kingston upon Thames 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 Kingston upon Thames home.
Where would the outdoor unit go on a Kingston upon Thames 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 Kingston upon Thames home.
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.
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.
