Oil and LPG boiler replacement for Knowle homes
Every property in Knowle is different, so the design starts from measurements rather than a rule of thumb. That keeps the system the right size and the running costs predictable.
Owners across the West Midlands can have oil tank removal arranged alongside a heat pump installation in Knowle. Bungalows and detached houses near Knowle running on LPG can move to a heat pump, with the tank collected by the supplier.
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
- Free survey with a detailed heat loss calculation for older construction
- MCS certificate and grant application in England and Wales where eligible
- Oil tank draining and removal or making safe, as set out in your quote
- Help arranging LPG tank collection with your supplier
- Removal of the oil or LPG boiler and flue
If your home near Knowle is off the mains gas grid, a heat pump removes the need for oil or LPG deliveries.
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 Knowle 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.

Short winter days in Knowle and what they mean

Replacing an oil or LPG boiler with a heat pump in Knowle: questions
How long does installation take in Knowle?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Knowle home states the expected time.
How long does a heat pump survey take in Knowle?
A home survey in Knowle 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.
Do I need new radiators for a heat pump in Knowle?
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 Knowle home gives a room-by-room list.
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.
