Oil and LPG boiler replacement in Liverpool: what to expect
Most homes can run on a heat pump if the system is designed properly, and Liverpool is no different. The key is matching the heat pump and radiators to the home's heat loss.
If your home near Liverpool is off the mains gas grid, a heat pump removes the need for oil or LPG deliveries. Owners across Merseyside can have oil tank removal arranged alongside a heat pump installation in Liverpool.
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.
- Eligible homes in England and Wales within the higher grant window
- Owners tired of fuel deliveries and tank maintenance
- Older oil boilers nearing the end of their life
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
- Help arranging LPG tank collection with your supplier
- Oil tank draining and removal or making safe, as set out in your quote
- Outdoor unit, heat pump cylinder, controls and radiator changes
Bungalows and detached houses near Liverpool running on LPG can move to a heat pump, with the tank collected by the supplier.
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 Liverpool 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.
What to budget for replacing an oil or LPG boiler with a heat pump in Liverpool
These are guide prices for Merseyside, installed and including VAT. Your final price is fixed in a written quote after the survey and depends on the heat loss of the house, the radiators that need changing and where the unit goes.

|---|---|---|---|
| 1–2 bedroom flat or small terrace | 4–5 kW | £9,200–£12,150 | £200–£3,150 |
| 2–3 bedroom terrace or semi | 5–7 kW | £10,200–£13,100 | £1,200–£4,100 |

Short winter days in Liverpool and what they mean
On the shortest day Liverpool gets only about 7 hours 29 minutes of daylight and the noon sun sits around 13° above the horizon. Northern winters tend to be longer, so a well-designed, efficient system matters more here because it runs for more of the year.

Replacing an oil or LPG boiler with a heat pump in Liverpool: questions
Do you cover Birkenhead as well as Liverpool?
Yes. We arrange surveys and installation in Birkenhead, which is about 2 miles south-west of Liverpool, and across Merseyside.
What size heat pump does a Liverpool 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 Liverpool home.
How long does installation take in Liverpool?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Liverpool home states the expected time.
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.
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.
