Heat pump radiators in Newhaven: what to expect
Most homes can run on a heat pump if the system is designed properly, and Newhaven is no different. The key is matching the heat pump and radiators to the home's heat loss.
Extensions and kitchen-diners around Newhaven with large glazed areas get their own radiator calculation. In Newhaven, bay-windowed front rooms are often the rooms that need a larger radiator when moving to a heat pump.
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
- 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
- Supply and fitting of new radiators, valves and brackets
- Pipework checks and any agreed pipe upgrades
- Making good around brackets and pipe routes, with any decorating agreed in your quote
- Draining, refilling, cleaning and inhibitor treatment of the heating system
- Room-by-room heat loss figures for every heated room
We plan radiator upgrades in Newhaven so floorboards are lifted only where pipework genuinely needs changing.
Grants and rules for heat pumps in England
Homes in Newhaven 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.
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.

Short winter days in Newhaven and what they mean

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