Oil and LPG boiler replacement for Bishopston homes
A heat pump suits most Bishopston homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
Bungalows and detached houses near Bishopston running on LPG can move to a heat pump, with the tank collected by the supplier. If your home near Bishopston 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.
- Detached houses and bungalows with garden space for the unit
- Older oil boilers nearing the end of their life
- Eligible homes in England and Wales within the higher grant window
What's included
- Oil tank draining and removal or making safe, as set out in your quote
- Removal of the oil or LPG boiler and flue
- Outdoor unit, heat pump cylinder, controls and radiator changes
- MCS certificate and grant application in England and Wales where eligible
- Network operator notification and electrical connection
Owners across Bristol can have oil tank removal arranged alongside a heat pump installation in Bishopston.
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 Bishopston 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 Bishopston?
Bishopston sees roughly 7 hours 50 minutes of daylight in late December against 16 hours 38 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 Bishopston: questions
What size heat pump does a Bishopston 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 Bishopston home.
Do I need new radiators for a heat pump in Bishopston?
Often some, not all. Heat pumps run best at lower water temperatures, so rooms with small radiators may need larger ones. The survey of your Bishopston home gives a room-by-room list.
Do you cover Westbury-on-Trym as well as Bishopston?
Yes. We arrange surveys and installation in Westbury-on-Trym, which is about a mile north-west of Bishopston, and across Bristol.
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.
