What to know about heat pump radiator upgrades in St Austell
Homes around St Austell range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
Radiator fitting in St Austell is scheduled with your heat pump installation so the system is drained only once. For period homes in St Austell and across Cornwall, 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
- Extensions and loft conversions with large areas of glazing
- Homes switching from a gas, oil or LPG boiler to a heat pump
What's included
- Draining, refilling, cleaning and inhibitor treatment of the heating system
- Balancing every radiator so each room heats evenly
- Supply and fitting of new radiators, valves and brackets
- Pipework checks and any agreed pipe upgrades
- A radiator schedule showing which radiators stay, which change and their outputs
In St Austell, bay-windowed front rooms are often the rooms that need a larger radiator when moving to a heat pump.
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 St Austell 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.
Heat pump radiators prices in St Austell

Installed, inc VAT. The survey lists which radiators need changing.
Designing for St Austell's winters
St Austell 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.

- We commission the heat pump, show you the controls and register the installation.
Heat pump radiator upgrades in St Austell: questions
Can you service a heat pump in St Austell that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in St Austell, whoever fitted them. Tell us the make and model when you book.
Where would the outdoor unit go on a St Austell 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 St Austell home.
Do you cover Bodmin as well as St Austell?
Yes. We arrange surveys and installation in Bodmin, which is about 9 miles north of St Austell, and across Cornwall.
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.
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.
