What to know about heat pump radiator upgrades in Wymondham
Homes around Wymondham range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
We plan radiator upgrades in Wymondham so floorboards are lifted only where pipework genuinely needs changing. Extensions and kitchen-diners around Wymondham with large glazed areas get their own radiator calculation.
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 that already feel slow to heat, such as bay-windowed living rooms
- Rooms with little wall space, where a fan-assisted radiator fits better
What's included
- Balancing every radiator so each room heats evenly
- Supply and fitting of new radiators, valves and brackets
- A radiator schedule showing which radiators stay, which change and their outputs
- Room-by-room heat loss figures for every heated room
- Draining, refilling, cleaning and inhibitor treatment of the heating system
For period homes in Wymondham and across Norfolk, column radiators can keep the character of a room while giving enough heat at low temperatures.
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 Wymondham 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 radiators prices in Wymondham
The ranges below are typical installed prices for homes in Norfolk, including VAT. A survey sets the exact figure, because two similar-looking houses in Wymondham can need quite different radiators and pipework.
| Work | Guide price |
|---|---|
| Replacement radiator, sized for a heat pump (each, fitted) | £250–£450 |
| Upgrade of about 10 radiators | £2,000–£5,000 |
| Pipework upgrade (e.g. microbore to larger bore) | £1,500–£3,500 |
Installed, inc VAT. The survey lists which radiators need changing.
How long is the heating season in Wymondham?
Wymondham has about 7 hours 38 minutes of daylight at midwinter and 16 hours 51 minutes at midsummer. That swing matters if you pair a heat pump with solar panels: summer generation can cover much of the hot water, winter generation far less.

- The design and quote arrive in writing, including radiator changes and the outdoor unit position.
- On installation days the old system is removed and the new one fitted and filled.
- We commission the heat pump, show you the controls and register the installation.
Heat pump radiator upgrades in Wymondham: questions
Can you service a heat pump in Wymondham that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Wymondham, whoever fitted them. Tell us the make and model when you book.
Where would the outdoor unit go on a Wymondham 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 Wymondham home.
What size heat pump does a Wymondham 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 Wymondham home.
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.
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.
