Oil and LPG boiler replacement for Ventnor homes
The question for a Ventnor 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 Ventnor reached by a long drive or narrow lane, delivery of the unit and cylinder is planned in advance. If your home near Ventnor 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.
- Owners tired of fuel deliveries and tank maintenance
- Older oil boilers nearing the end of their life
- Rural and village homes off the mains gas grid
What's included
- Oil tank draining and removal or making safe, as set out in your quote
- Outdoor unit, heat pump cylinder, controls and radiator changes
- Removal of the oil or LPG boiler and flue
- MCS certificate and grant application in England and Wales where eligible
- Free survey with a detailed heat loss calculation for older construction
Owners across the Isle of Wight can have oil tank removal arranged alongside a heat pump installation in Ventnor.
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 Ventnor 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.

How long is the heating season in Ventnor?
On the shortest day Ventnor gets about 7 hours 59 minutes of daylight, and the winter sun reaches only around 16° 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 Ventnor: questions
Where would the outdoor unit go on a Ventnor house?
Usually at the side or rear, on a level base with space around it for airflow and servicing, away from bedroom windows where possible. The surveyor checks positions at your Ventnor home.
Can you service a heat pump in Ventnor that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Ventnor, whoever fitted them. Tell us the make and model when you book.
How soon can you survey a home in Ventnor?
Survey dates depend on how busy installers are in the Isle of Wight. We offer the next available dates when you enquire and confirm them in writing.
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.
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.
