Before you book: heat pump radiator upgrades in Folkestone
In Folkestone, 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.
Radiator fitting in Folkestone is scheduled with your heat pump installation so the system is drained only once. We plan radiator upgrades in Folkestone 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.
- Homes switching from a gas, oil or LPG boiler to a heat pump
- Rooms that already feel slow to heat, such as bay-windowed living rooms
- Extensions and loft conversions with large areas of glazing
What's included
- Pipework checks and any agreed pipe upgrades
- A radiator schedule showing which radiators stay, which change and their outputs
- Draining, refilling, cleaning and inhibitor treatment of the heating system
- Room-by-room heat loss figures for every heated room
- Balancing every radiator so each room heats evenly
Extensions and kitchen-diners around Folkestone with large glazed areas get their own radiator calculation.
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 Folkestone quote.
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.
Guide prices for heat pump radiator upgrades in Folkestone
These are guide prices for Kent, 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) | £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 Folkestone and what they mean
Folkestone sees roughly 7 hours 54 minutes of daylight in late December against 16 hours 34 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 Folkestone
- Send your postcode and a few details, or use the guide price tool.
- A surveyor visits your Folkestone 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 Folkestone: questions
What size heat pump does a Folkestone 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 Folkestone home.
Do I need new radiators for a heat pump in Folkestone?
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 Folkestone home gives a room-by-room list.
How long does installation take in Folkestone?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Folkestone 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.
Can radiators be changed without draining the whole system?
Radiator changes normally mean draining the heating system, which is why they are usually done as part of the heat pump installation. The system is then refilled, flushed, treated with inhibitor and balanced. Doing the radiators at the same time avoids draining twice and means the new radiators are commissioned with the heat pump.
