Oil and LPG boiler replacement in Midhurst: what to expect
In Midhurst, as anywhere in the UK, the heat pumps that perform well are the ones designed around low flow temperatures and sized from a proper heat loss calculation.
For homes outside Midhurst reached by a long drive or narrow lane, delivery of the unit and cylinder is planned in advance. Rural properties near Midhurst usually have garden space for the outdoor unit, sited away from windows and sheltered where possible.
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
- Rural and village homes off the mains gas grid
- Owners tired of fuel deliveries and tank maintenance
What's included
- Outdoor unit, heat pump cylinder, controls and radiator changes
- Removal of the oil or LPG boiler and flue
- Help arranging LPG tank collection with your supplier
- MCS certificate and grant application in England and Wales where eligible
- Free survey with a detailed heat loss calculation for older construction
Owners across West Sussex can have oil tank removal arranged alongside a heat pump installation in Midhurst.
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 Midhurst 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.

Replacing an oil or LPG boiler with a heat pump in Midhurst: questions
Do you cover Petworth as well as Midhurst?
Yes. We arrange surveys and installation in Petworth, which is about 6 miles east of Midhurst, and across West Sussex.
How long does a heat pump survey take in Midhurst?
A home survey in Midhurst 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.
How long does installation take in Midhurst?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Midhurst home states the expected time.
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.
Is a heat pump cheaper to run than oil?
It depends on oil prices, your home's insulation, the flow temperature and your electricity tariff, so there is no single answer. At the October to December 2026 price cap, a heat pump with a seasonal efficiency of 3.0 delivers heat for about 8.8p per kWh, and at 3.5 about 7.5p. Compare that with your oil cost per kWh of heat, allowing for your boiler's efficiency; the survey estimate gives a figure for your home.
