Before you book: heat pump radiator upgrades in Egham
The question for an Egham 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.
We plan radiator upgrades in Egham so floorboards are lifted only where pipework genuinely needs changing. Radiator fitting in Egham 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
- 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
- Room-by-room heat loss figures for every heated room
- Draining, refilling, cleaning and inhibitor treatment of the heating system
- A radiator schedule showing which radiators stay, which change and their outputs
Extensions and kitchen-diners around Egham 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 Egham 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.
What to budget for heat pump radiator upgrades in Egham
These are guide prices for Surrey, 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) | £270–£480 |
| Upgrade of about 10 radiators | £2,150–£5,350 |
| Pipework upgrade (e.g. microbore to larger bore) | £1,600–£3,750 |
Installed, inc VAT. The survey lists which radiators need changing.
How long is the heating season in Egham?
Egham sees roughly 7 hours 50 minutes of daylight in late December against 16 hours 38 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.
The steps for heat pump radiator upgrades in Egham
- Send your postcode and a few details, or use the guide price tool.
- A surveyor visits your Egham 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 Egham: questions
How long does a heat pump survey take in Egham?
A home survey in Egham 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.
Do you cover Woking as well as Egham?
Yes. We arrange surveys and installation in Woking, which is about 8 miles south of Egham, and across Surrey.
Do I need new radiators for a heat pump in Egham?
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 Egham 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.
