What to know about heat pump radiator upgrades in Cranleigh
Every property in Cranleigh is different, so the design starts from measurements rather than a rule of thumb. That keeps the system the right size and the running costs predictable.
Radiator fitting in Cranleigh is scheduled with your heat pump installation so the system is drained only once. Extensions and kitchen-diners around Cranleigh 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.
- Extensions and loft conversions with large areas of glazing
- Homeowners who want the lowest practical flow temperature for efficiency
- Rooms with little wall space, where a fan-assisted radiator fits better
What's included
- Making good around brackets and pipe routes, with any decorating agreed in your quote
- Draining, refilling, cleaning and inhibitor treatment of the heating system
- Pipework checks and any agreed pipe upgrades
- Supply and fitting of new radiators, valves and brackets
- Balancing every radiator so each room heats evenly
For period homes in Cranleigh and across Surrey, 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 Cranleigh 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 Cranleigh
The ranges below are typical installed prices for homes in Surrey, including VAT. A survey sets the exact figure, because two similar-looking houses in Cranleigh can need quite different radiators and pipework.
| 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.
Winter daylight and heating in Cranleigh
Cranleigh sees roughly 7 hours 53 minutes of daylight in late December against 16 hours 34 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 Cranleigh: questions
How long does installation take in Cranleigh?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Cranleigh home states the expected time.
Do you cover Godalming as well as Cranleigh?
Yes. We arrange surveys and installation in Godalming, which is about 6 miles north-west of Cranleigh, and across Surrey.
How long does a heat pump survey take in Cranleigh?
A home survey in Cranleigh 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.
Will new radiators be much bigger than my old ones?
Sometimes, but not always. Swapping a single-panel radiator for a double or triple-panel model of the same height and width can raise output substantially, adding only depth from the wall. Where that is not enough, a longer or taller radiator, or a second radiator in the room, may be needed. We agree sizes and positions with you before anything is ordered.
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.
