Oil and LPG boiler replacement in Littlehampton: what to expect
Most homes can run on a heat pump if the system is designed properly, and Littlehampton is no different. The key is matching the heat pump and radiators to the home's heat loss.
Owners across West Sussex can have oil tank removal arranged alongside a heat pump installation in Littlehampton. Bungalows and detached houses near Littlehampton 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
- Owners tired of fuel deliveries and tank maintenance
- Older oil boilers nearing the end of their life
What's included
- Help arranging LPG tank collection with your supplier
- Network operator notification and electrical connection
- Outdoor unit, heat pump cylinder, controls and radiator changes
- MCS certificate and grant application in England and Wales where eligible
- Removal of the oil or LPG boiler and flue
If your home near Littlehampton 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 Littlehampton quote.
There is no VAT on installing a heat pump anywhere in the UK until 31 March 2027. In England most houses can have an air source heat pump under permitted development, provided the unit meets the MCS noise and siting standards; the old 1 m boundary limit was removed on 29 May 2025. We flag listed buildings, flats and sensitive conservation-area positions at survey.

Replacing an oil or LPG boiler with a heat pump in Littlehampton: questions
Can you service a heat pump in Littlehampton that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Littlehampton, whoever fitted them. Tell us the make and model when you book.
How long does installation take in Littlehampton?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Littlehampton home states the expected time.
Where would the outdoor unit go on a Littlehampton house?
Usually at the side or rear, on a level base with space around it for airflow and servicing, away from bedroom windows where possible. The surveyor checks positions at your Littlehampton home.
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.
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.
