What to know about heat pump radiator upgrades in Bexhill-on-Sea
The question for a Bexhill-on-Sea 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.
In Bexhill-on-Sea, bay-windowed front rooms are often the rooms that need a larger radiator when moving to a heat pump. Radiator fitting in Bexhill-on-Sea 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.
- Homeowners who want the lowest practical flow temperature for efficiency
- Rooms with little wall space, where a fan-assisted radiator fits better
- Rooms that already feel slow to heat, such as bay-windowed living rooms
What's included
- Balancing every radiator so each room heats evenly
- Pipework checks and any agreed pipe upgrades
- Room-by-room heat loss figures for every heated room
- Supply and fitting of new radiators, valves and brackets
- Draining, refilling, cleaning and inhibitor treatment of the heating system
Many older houses in Bexhill-on-Sea still have their original single-panel radiators, so the survey checks each one against the room it heats.
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 Bexhill-on-Sea 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 radiator upgrades in Bexhill-on-Sea: questions
Do I need new radiators for a heat pump in Bexhill-on-Sea?
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 Bexhill-on-Sea home gives a room-by-room list.
Do you cover Battle as well as Bexhill-on-Sea?
Yes. We arrange surveys and installation in Battle, which is about 5 miles north of Bexhill-on-Sea, and across East Sussex.
How long does a heat pump survey take in Bexhill-on-Sea?
A home survey in Bexhill-on-Sea 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.
Can I keep my radiators and just run the heat pump hotter?
You can, but it usually costs more to run. Every extra degree of flow temperature reduces a heat pump's efficiency, so a system designed at 55°C uses noticeably more electricity than one at 45°C for the same heat. A few well-chosen radiator upgrades often let the whole house run cooler, which is the better long-term trade.
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.
