What to know about heat pump radiator upgrades in Haywards Heath
A heat pump suits most Haywards Heath homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
Radiator fitting in Haywards Heath is scheduled with your heat pump installation so the system is drained only once. We plan radiator upgrades in Haywards Heath 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.
- Homeowners who want the lowest practical flow temperature for efficiency
- Rooms with little wall space, where a fan-assisted radiator fits better
- Extensions and loft conversions with large areas of glazing
What's included
- 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
- Making good around brackets and pipe routes, with any decorating agreed in your quote
- A radiator schedule showing which radiators stay, which change and their outputs
In Haywards Heath, 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 Haywards Heath 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.
Heat pump radiators prices in Haywards Heath
The ranges below are typical installed prices for homes in West Sussex, including VAT. A survey sets the exact figure, because two similar-looking houses in Haywards Heath can need quite different radiators and pipework.
| Work | Guide price |
|---|---|
| Replacement radiator, sized for a heat pump (each, fitted) | £260–£470 |
| Upgrade of about 10 radiators | £2,100–£5,200 |
| Pipework upgrade (e.g. microbore to larger bore) | £1,550–£3,650 |
Installed, inc VAT. The survey lists which radiators need changing.
Short winter days in Haywards Heath and what they mean
Haywards Heath sees roughly 7 hours 55 minutes of daylight in late December against 16 hours 33 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.

Heat pump radiator upgrades in Haywards Heath: questions
Where would the outdoor unit go on a Haywards Heath 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 Haywards Heath home.
Do I need new radiators for a heat pump in Haywards Heath?
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 Haywards Heath home gives a room-by-room list.
Do you cover Burgess Hill as well as Haywards Heath?
Yes. We arrange surveys and installation in Burgess Hill, which is about 3 miles south-west of Haywards Heath, and across West Sussex.
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.
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.
