Oil and LPG boiler replacement for Haslemere homes
The question for a Haslemere 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.
For homes outside Haslemere reached by a long drive or narrow lane, delivery of the unit and cylinder is planned in advance. Bungalows and detached houses near Haslemere 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.
- Detached houses and bungalows with garden space for the unit
- Eligible homes in England and Wales within the higher grant window
- Owners tired of fuel deliveries and tank maintenance
What's included
- Free survey with a detailed heat loss calculation for older construction
- Network operator notification and electrical connection
- Oil tank draining and removal or making safe, as set out in your quote
- Outdoor unit, heat pump cylinder, controls and radiator changes
- MCS certificate and grant application in England and Wales where eligible
If your home near Haslemere is off the mains gas grid, a heat pump removes the need for oil or LPG deliveries.
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 Haslemere 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.

Designing for Haslemere's winters
On the shortest day Haslemere gets about 7 hours 54 minutes of daylight, and the winter sun reaches only around 15° above the horizon at noon. Winters this far south are milder than in most of the UK, which helps a heat pump run at low flow temperatures for much of the season.

Replacing an oil or LPG boiler with a heat pump in Haslemere: questions
How soon can you survey a home in Haslemere?
Survey dates depend on how busy installers are in Surrey. We offer the next available dates when you enquire and confirm them in writing.
How long does a heat pump survey take in Haslemere?
A home survey in Haslemere 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.
What size heat pump does a Haslemere home need?
It depends on the heat loss, not the postcode. As a rough guide, a 3 bedroom semi often needs 6–9 kW, but the room-by-room survey sets the actual size for your Haslemere home.
How much is the grant for replacing an oil boiler with a heat pump?
In England and Wales, the Boiler Upgrade Scheme grant is £9,000 when an air-to-water heat pump replaces oil or LPG heating, for installations from 21 July 2026 to 31 March 2027. Otherwise the standard £7,500 applies. The installer claims it and deducts it from your quote. Scotland's Home Energy Scotland funding works differently and includes extra for eligible rural homes; Northern Ireland has no dedicated homeowner scheme at present.
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.
