Oil and LPG boiler replacement for Gravesend homes
A heat pump suits most Gravesend homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
If your home near Gravesend is off the mains gas grid, a heat pump removes the need for oil or LPG deliveries. Owners across Kent can have oil tank removal arranged alongside a heat pump installation in Gravesend.
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
- Eligible homes in England and Wales within the higher grant window
What's included
- MCS certificate and grant application in England and Wales where eligible
- Free survey with a detailed heat loss calculation for older construction
- Removal of the oil or LPG boiler and flue
- Outdoor unit, heat pump cylinder, controls and radiator changes
- Oil tank draining and removal or making safe, as set out in your quote
Bungalows and detached houses near Gravesend running on LPG can move to a heat pump, with the tank collected by the supplier.
Grants and rules for heat pumps in England
Homes in Gravesend 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.

Replacing an oil or LPG boiler with a heat pump in Gravesend: questions
How long does a heat pump survey take in Gravesend?
A home survey in Gravesend 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 Gravesend 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 Gravesend home.
How long does installation take in Gravesend?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Gravesend home states the expected time.
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.
What happens with a leased LPG tank?
Leased LPG tanks belong to the supplier, so the supplier arranges collection. Check your contract for notice periods and any charges before you fix a date. We time the switchover so you are not left without heating, and once the heat pump is commissioned the supplier can empty and remove the tank. Bottled LPG cylinders are simply returned.
