Oil and LPG boiler replacement in Cobham: what to expect
Most homes can run on a heat pump if the system is designed properly, and Cobham is no different. The key is matching the heat pump and radiators to the home's heat loss.
Owners across Surrey can have oil tank removal arranged alongside a heat pump installation in Cobham. Cottages and farmhouses in and around Cobham often have solid walls, so the survey looks closely at construction and draughts.
Off-gas homes have a lot to plan when switching to a heat pump: the fuel tank, older walls, rural power supplies and higher heat loss.
- Owners tired of fuel deliveries and tank maintenance
- Detached houses and bungalows with garden space for the unit
- Rural and village homes off the mains gas grid
What's included
- Free survey with a detailed heat loss calculation for older construction
- Network operator notification and electrical connection
- MCS certificate and grant application in England and Wales where eligible
- Outdoor unit, heat pump cylinder, controls and radiator changes
- Removal of the oil or LPG boiler and flue
Bungalows and detached houses near Cobham running on LPG can move to a heat pump, with the tank collected by the supplier.
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 Cobham 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 replacing an oil or LPG boiler with a heat pump in Cobham
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 Cobham can need quite different radiators and pipework.

|---|---|---|---|
| 1–2 bedroom flat or small terrace | 4–5 kW | £10,150–£13,400 | £1,150–£4,400 |

Installed, inc VAT: unit, cylinder, controls, minor pipework and commissioning. The £9,000 Boiler Upgrade Scheme figure applies to oil and LPG replacements in England and Wales installed from 21 July 2026 to 31 March 2027.
Short winter days in Cobham and what they mean
Cobham sees roughly 7 hours 51 minutes of daylight in late December against 16 hours 36 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 Cobham
- Send your postcode and a few details, or use the guide price tool.
- A surveyor visits your Cobham 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.
Replacing an oil or LPG boiler with a heat pump in Cobham: questions
Do I need new radiators for a heat pump in Cobham?
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 Cobham home gives a room-by-room list.
Do you cover Woking as well as Cobham?
Yes. We arrange surveys and installation in Woking, which is about 6 miles west of Cobham, and across Surrey.
Can you service a heat pump in Cobham that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Cobham, whoever fitted them. Tell us the make and model when you book.
What happens with a leased LPG tank?
Leased LPG tanks belong to the supplier, so the supplier arranges collection. Check your contract for notice periods and any charges before you fix a date. We time the switchover so you are not left without heating, and once the heat pump is commissioned the supplier can empty and remove the tank. Bottled LPG cylinders are simply returned.
Will I need bigger radiators in an older cottage or farmhouse?
Often in some rooms, because thick solid walls and older windows lose more heat, and heat pumps work at lower water temperatures than oil boilers. The survey checks each room. Rooms with high ceilings or large windows are common candidates for a larger radiator. Where swapping radiators is impractical, a high-temperature unit can be considered, with lower efficiency as the trade-off.
