Oil and LPG boiler replacement in Horncastle: what to expect
The question for a Horncastle home is rarely whether a heat pump can work, but what needs to change to make it work well: radiator sizes, pipework, controls and where the unit goes.
Bungalows and detached houses near Horncastle running on LPG can move to a heat pump, with the tank collected by the supplier. If your home near Horncastle is off the mains gas grid, a heat pump removes the need for oil or LPG deliveries.
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.
- Older oil boilers nearing the end of their life
- Eligible homes in England and Wales within the higher grant window
- Owners tired of fuel deliveries and tank maintenance
What's included
- Network operator notification and electrical connection
- Oil tank draining and removal or making safe, as set out in your quote
- Outdoor unit, heat pump cylinder, controls and radiator changes
- MCS certificate and grant application in England and Wales where eligible
- Free survey with a detailed heat loss calculation for older construction
Cottages and farmhouses in and around Horncastle often have solid walls, so the survey looks closely at construction and draughts.
Grants and rules for heat pumps in England
Homes in Horncastle 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.

Replacing an oil or LPG boiler with a heat pump in Horncastle: questions
Where would the outdoor unit go on a Horncastle 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 Horncastle home.
How long does installation take in Horncastle?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Horncastle home states the expected time.
Can you service a heat pump in Horncastle that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Horncastle, whoever fitted them. Tell us the make and model when you book.
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.
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.
