What to know about heat pump radiator upgrades in Farnham
The question for a Farnham 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.
Many older houses in Farnham still have their original single-panel radiators, so the survey checks each one against the room it heats. We plan radiator upgrades in Farnham so floorboards are lifted only where pipework genuinely needs changing.
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.
- 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
- Extensions and loft conversions with large areas of glazing
What's included
- Room-by-room heat loss figures for every heated room
- Making good around brackets and pipe routes, with any decorating agreed in your quote
- Draining, refilling, cleaning and inhibitor treatment of the heating system
- Balancing every radiator so each room heats evenly
- Supply and fitting of new radiators, valves and brackets
For period homes in Farnham 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 Farnham quote.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Since 29 May 2025, permitted development in England allows up to two air source heat pumps on a house, each up to 1.5 m³, with no blanket 1 m boundary rule — the installation must still meet the MCS planning standards, including the noise check. Listed buildings, flats and some conservation-area positions need extra consent, which we check at survey.
Heat pump radiators prices in Farnham
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 Farnham 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 Farnham
Farnham 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.
How installation works in Farnham
- Send your postcode and a few details, or use the guide price tool.
- A surveyor visits your Farnham 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 Farnham: questions
How long does installation take in Farnham?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Farnham home states the expected time.
Where would the outdoor unit go on a Farnham 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 Farnham home.
Do you cover Aldershot as well as Farnham?
Yes. We arrange surveys and installation in Aldershot, which is about 3 miles north-east of Farnham, and across Surrey.
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.
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.
