Oil and LPG boiler replacement in Haywards Heath: what to expect
Every property in Haywards Heath 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 Haywards Heath is off the mains gas grid, a heat pump removes the need for oil or LPG deliveries. For homes outside Haywards Heath reached by a long drive or narrow lane, delivery of the unit and cylinder is planned in advance.
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.
- Owners tired of fuel deliveries and tank maintenance
- Eligible homes in England and Wales within the higher grant window
- Detached houses and bungalows with garden space for the unit
What's included
- Oil tank draining and removal or making safe, as set out in your quote
- Help arranging LPG tank collection with your supplier
- 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
Bungalows and detached houses near Haywards Heath running on LPG can move to a heat pump, with the tank collected by the supplier.
Grants and rules for heat pumps in England
Homes in Haywards Heath 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.
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.

How long is the heating season in Haywards Heath?
On the shortest day Haywards Heath gets about 7 hours 55 minutes of daylight, and the winter sun reaches only around 16° above the horizon at noon. Winters this far south are milder than in most of the UK, which helps a heat pump run at low flow temperatures for much of the season.

Replacing an oil or LPG boiler with a heat pump in Haywards Heath: questions
How soon can you survey a home in Haywards Heath?
Survey dates depend on how busy installers are in West Sussex. We offer the next available dates when you enquire and confirm them in writing.
What size heat pump does a Haywards Heath 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 Haywards Heath home.
Do you cover Burgess Hill as well as Haywards Heath?
Yes. We arrange surveys and installation in Burgess Hill, which is about 3 miles south-west of Haywards Heath, and across West Sussex.
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.
