What to know about replacing an oil or LPG boiler with a heat pump in Leigh
Every property in Leigh 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.
If your home near Leigh is off the mains gas grid, a heat pump removes the need for oil or LPG deliveries. Bungalows and detached houses near Leigh 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
- MCS certificate and grant application in England and Wales where eligible
- Outdoor unit, heat pump cylinder, controls and radiator changes
- Network operator notification and electrical connection
- Free survey with a detailed heat loss calculation for older construction
- Help arranging LPG tank collection with your supplier
Owners across Greater Manchester can have oil tank removal arranged alongside a heat pump installation in Leigh.
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 Leigh 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.

Replacing an oil or LPG boiler with a heat pump in Leigh: questions
Can you service a heat pump in Leigh that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Leigh, whoever fitted them. Tell us the make and model when you book.
What size heat pump does a Leigh 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 Leigh home.
Do you cover Atherton as well as Leigh?
Yes. We arrange surveys and installation in Atherton, which is about 2 miles north-east of Leigh, and across Greater Manchester.
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.
