Oil and LPG boiler replacement in Shoreham-by-Sea: what to expect
Most homes can run on a heat pump if the system is designed properly, and Shoreham-by-Sea is no different. The key is matching the heat pump and radiators to the home's heat loss.
Rural properties near Shoreham-by-Sea usually have garden space for the outdoor unit, sited away from windows and sheltered where possible. Owners across West Sussex can have oil tank removal arranged alongside a heat pump installation in Shoreham-by-Sea.
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.
- Rural and village homes off the mains gas grid
- Eligible homes in England and Wales within the higher grant window
- Detached houses and bungalows with garden space for the unit
What's included
- MCS certificate and grant application in England and Wales where eligible
- Network operator notification and electrical connection
- Free survey with a detailed heat loss calculation for older construction
- Oil tank draining and removal or making safe, as set out in your quote
- Removal of the oil or LPG boiler and flue
Bungalows and detached houses near Shoreham-by-Sea 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 Shoreham-by-Sea 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.

- We commission the heat pump, show you the controls and register the installation.
Replacing an oil or LPG boiler with a heat pump in Shoreham-by-Sea: questions
Do you cover Worthing as well as Shoreham-by-Sea?
Yes. We arrange surveys and installation in Worthing, which is about 5 miles west of Shoreham-by-Sea, and across West Sussex.
Do I need new radiators for a heat pump in Shoreham-by-Sea?
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 Shoreham-by-Sea home gives a room-by-room list.
How long does installation take in Shoreham-by-Sea?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Shoreham-by-Sea home states the expected time.
Can a heat pump cope with an exposed rural spot?
Yes. Air source heat pumps are designed to keep working well below freezing, and they periodically defrost, giving off a little vapour, which is normal. In exposed locations the installer chooses a sheltered position where possible, raises the unit to clear snow and let defrost water drain, and sizes the system for the local winter design temperature used in the heat loss calculation.
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.
