Heat pump radiators for Plymouth homes
In Plymouth, 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.
Many older houses in Plymouth still have their original single-panel radiators, so the survey checks each one against the room it heats. For period homes in Plymouth and across Devon, column radiators can keep the character of a room while giving enough heat at low temperatures.
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 that already feel slow to heat, such as bay-windowed living rooms
- Homes switching from a gas, oil or LPG boiler to a heat pump
- Extensions and loft conversions with large areas of glazing
What's included
- Room-by-room heat loss figures for every heated room
- Making good around brackets and pipe routes, with any decorating agreed in your quote
- Balancing every radiator so each room heats evenly
- Pipework checks and any agreed pipe upgrades
- Draining, refilling, cleaning and inhibitor treatment of the heating system
We plan radiator upgrades in Plymouth so floorboards are lifted only where pipework genuinely needs changing.
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 Plymouth 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 Plymouth
These are guide prices for Devon, 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) | £250–£450 |
| Upgrade of about 10 radiators | £2,000–£5,050 |
| Pipework upgrade (e.g. microbore to larger bore) | £1,500–£3,550 |
Installed, inc VAT. The survey lists which radiators need changing.
Winter daylight and heating in Plymouth
Plymouth sees roughly 8 hours 01 minutes of daylight in late December against 16 hours 26 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 heat pump radiator upgrades in Plymouth
- Tell us about your home: postcode, property type and current heating.
- We book a survey in Plymouth; 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 Plymouth: questions
Do you cover Saltash as well as Plymouth?
Yes. We arrange surveys and installation in Saltash, which is about 4 miles north-west of Plymouth, and across Devon.
Where would the outdoor unit go on a Plymouth 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 Plymouth home.
How long does installation take in Plymouth?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Plymouth home states the expected time.
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.
