What to know about replacing an oil or LPG boiler with a heat pump in Egham
Homes around Egham range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
Cottages and farmhouses in and around Egham often have solid walls, so the survey looks closely at construction and draughts. Bungalows and detached houses near Egham running on LPG can move to a heat pump, with the tank collected by the supplier.
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.
- Older oil boilers nearing the end of their life
- Eligible homes in England and Wales within the higher grant window
- Detached houses and bungalows with garden space for the unit
What's included
- MCS certificate and grant application in England and Wales where eligible
- Help arranging LPG tank collection with your supplier
- Network operator notification and electrical connection
- Free survey with a detailed heat loss calculation for older construction
- Outdoor unit, heat pump cylinder, controls and radiator changes
Rural properties near Egham usually have garden space for the outdoor unit, sited away from windows and sheltered where possible.
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.

Designing for Egham's winters
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.

Replacing an oil or LPG boiler with a heat pump in Egham: questions
How long does installation take in Egham?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for an Egham home states the expected time.
How soon can you survey a home in Egham?
Survey dates depend on how busy installers are in Surrey. We offer the next available dates when you enquire and confirm them in writing.
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 have to remove my oil tank?
Not always, but it should be emptied and made safe. A tank in good condition can be drained, cleaned and left in place, though most owners prefer to have it taken away to free up space. Old or damaged tanks are usually removed. Your quote says which option is included, and any remaining oil and sludge is disposed of properly.
Can a heat pump cope with an exposed rural spot?
Yes. Air source heat pumps are designed to keep working well below freezing, and they periodically defrost, giving off a little vapour, which is normal. In exposed locations the installer chooses a sheltered position where possible, raises the unit to clear snow and let defrost water drain, and sizes the system for the local winter design temperature used in the heat loss calculation.
