Before you book: heat pump radiator upgrades in Falmouth
The question for a Falmouth home is rarely whether a heat pump can work, but what needs to change to make it work well: radiator sizes, pipework, controls and where the unit goes.
Many older houses in Falmouth still have their original single-panel radiators, so the survey checks each one against the room it heats. Radiator fitting in Falmouth 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.
- Extensions and loft conversions with large areas of glazing
- Homeowners who want the lowest practical flow temperature for efficiency
- Rooms with little wall space, where a fan-assisted radiator fits better
What's included
- A radiator schedule showing which radiators stay, which change and their outputs
- Supply and fitting of new radiators, valves and brackets
- Pipework checks and any agreed pipe upgrades
- Room-by-room heat loss figures for every heated room
- Draining, refilling, cleaning and inhibitor treatment of the heating system
Extensions and kitchen-diners around Falmouth with large glazed areas get their own radiator calculation.
Grants and rules for heat pumps in England
Homes in Falmouth 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 Falmouth
The ranges below are typical installed prices for homes in Cornwall, including VAT. A survey sets the exact figure, because two similar-looking houses in Falmouth can need quite different radiators and pipework.
| 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.
Short winter days in Falmouth and what they mean
Falmouth sees roughly 8 hours 03 minutes of daylight in late December against 16 hours 24 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.
How installation works in Falmouth
- Send your postcode and a few details, or use the guide price tool.
- A surveyor visits your Falmouth home, measures every room and checks where the outdoor unit can go.
- You receive a heat loss design and a fixed written quote, with any grant shown where it applies.
- Installers fit the unit, cylinder and any radiator changes, typically over 2–4 days on site.
- The system is commissioned, set up with weather compensation and handed over with the paperwork.
Heat pump radiator upgrades in Falmouth: questions
Do I need new radiators for a heat pump in Falmouth?
Often some, not all. Heat pumps run best at lower water temperatures, so rooms with small radiators may need larger ones. The survey of your Falmouth home gives a room-by-room list.
How long does a heat pump survey take in Falmouth?
A home survey in Falmouth 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 Falmouth 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 Falmouth home.
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.
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.
