Oil and LPG boiler replacement in Newhaven: what to expect
Most homes can run on a heat pump if the system is designed properly, and Newhaven is no different. The key is matching the heat pump and radiators to the home's heat loss.
For homes outside Newhaven reached by a long drive or narrow lane, delivery of the unit and cylinder is planned in advance. Owners across East Sussex can have oil tank removal arranged alongside a heat pump installation in Newhaven.
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
- Network operator notification and electrical connection
- Outdoor unit, heat pump cylinder, controls and radiator changes
- Help arranging LPG tank collection with your supplier
- Removal of the oil or LPG boiler and flue
- MCS certificate and grant application in England and Wales where eligible
Rural properties near Newhaven usually have garden space for the outdoor unit, sited away from windows and sheltered where possible.
Grants and rules for heat pumps in England
Homes in Newhaven can use the Boiler Upgrade Scheme, which takes £7,500 off the cost of an air source heat pump when it replaces fossil-fuel or electric heating. Replacing oil or LPG heating qualifies for £9,000 for installations from 21 July 2026 to 31 March 2027, and air-to-air systems for £2,500. The MCS-certified installer named in your quote applies for the grant and deducts it from the price.
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 Newhaven: questions
What size heat pump does a Newhaven 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 Newhaven home.
How long does installation take in Newhaven?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Newhaven home states the expected time.
How soon can you survey a home in Newhaven?
Survey dates depend on how busy installers are in East Sussex. We offer the next available dates when you enquire and confirm them in writing.
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.
How much is the grant for replacing an oil boiler with a heat pump?
In England and Wales, the Boiler Upgrade Scheme grant is £9,000 when an air-to-water heat pump replaces oil or LPG heating, for installations from 21 July 2026 to 31 March 2027. Otherwise the standard £7,500 applies. The installer claims it and deducts it from your quote. Scotland's Home Energy Scotland funding works differently and includes extra for eligible rural homes; Northern Ireland has no dedicated homeowner scheme at present.
