Heat pump radiators in Guildford: what to expect
Every property in Guildford 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.
Extensions and kitchen-diners around Guildford with large glazed areas get their own radiator calculation. For period homes in Guildford and across Surrey, column radiators can keep the character of a room while giving enough heat at low temperatures.
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
- Homes switching from a gas, oil or LPG boiler to a heat pump
- Rooms with little wall space, where a fan-assisted radiator fits better
What's included
- Draining, refilling, cleaning and inhibitor treatment of the heating system
- Pipework checks and any agreed pipe upgrades
- Balancing every radiator so each room heats evenly
- Room-by-room heat loss figures for every heated room
- Making good around brackets and pipe routes, with any decorating agreed in your quote
Radiator fitting in Guildford is scheduled with your heat pump installation so the system is drained only once.
Grants and rules for heat pumps in England
Homes in Guildford 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.
Heat pump radiators prices in Guildford
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.
Short winter days in Guildford and what they mean
Guildford sees roughly 7 hours 52 minutes of daylight in late December against 16 hours 35 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.
From survey to switch-on in Guildford
- Send your postcode and a few details, or use the guide price tool.
- A surveyor visits your Guildford 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 Guildford: questions
How long does a heat pump survey take in Guildford?
A home survey in Guildford 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 Godalming as well as Guildford?
Yes. We arrange surveys and installation in Godalming, which is about 4 miles south-west of Guildford, and across Surrey.
Can you service a heat pump in Guildford that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Guildford, whoever fitted them. Tell us the make and model when you book.
Are fan-assisted radiators noisy?
Fan-assisted radiators make a low, steady fan sound when running at higher output, and many have quieter settings for bedrooms at night. They are useful where wall space is short, such as a kitchen with few clear walls. They need a small electrical supply, which we plan into the installation if you choose them.
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.
