What to know about replacing an oil or LPG boiler with a heat pump in Emsworth
Homes around Emsworth range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
Bungalows and detached houses near Emsworth running on LPG can move to a heat pump, with the tank collected by the supplier. If your home near Emsworth is off the mains gas grid, a heat pump removes the need for oil or LPG deliveries.
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.
- Eligible homes in England and Wales within the higher grant window
- Detached houses and bungalows with garden space for the unit
- Rural and village homes off the mains gas grid
What's included
- Help arranging LPG tank collection with your supplier
- MCS certificate and grant application in England and Wales where eligible
- Network operator notification and electrical connection
- Removal of the oil or LPG boiler and flue
- Oil tank draining and removal or making safe, as set out in your quote
For homes outside Emsworth reached by a long drive or narrow lane, delivery of the unit and cylinder is planned in advance.
Grants and rules for heat pumps in England
Homes in Emsworth 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.
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 Emsworth's winters
Emsworth sees roughly 7 hours 56 minutes of daylight in late December against 16 hours 31 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 Emsworth: questions
How long does installation take in Emsworth?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for an Emsworth home states the expected time.
Do you cover Havant as well as Emsworth?
Yes. We arrange surveys and installation in Havant, which is about 2 miles west of Emsworth, and across West Sussex.
Can you service a heat pump in Emsworth that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Emsworth, whoever fitted them. Tell us the make and model when you book.
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.
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.
