Before you book: replacing an oil or LPG boiler with a heat pump in Prestwick
The question for a Prestwick 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.
Owners across Ayrshire can have oil tank removal arranged alongside a heat pump installation in Prestwick. Cottages and farmhouses in and around Prestwick often have solid walls, so the survey looks closely at construction and draughts.
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
- Detached houses and bungalows with garden space for the unit
- Owners tired of fuel deliveries and tank maintenance
What's included
- Free survey with a detailed heat loss calculation for older construction
- Help arranging LPG tank collection with your supplier
- Network operator notification and electrical connection
- Outdoor unit, heat pump cylinder, controls and radiator changes
- Oil tank draining and removal or making safe, as set out in your quote
For homes outside Prestwick reached by a long drive or narrow lane, delivery of the unit and cylinder is planned in advance.
Grants and rules for heat pumps in Scotland
In Scotland, heat pump funding comes through Home Energy Scotland rather than the Boiler Upgrade Scheme: a grant of up to £7,500 (up to £1,500 extra for eligible rural and island homes) and an optional interest-free loan of up to £7,500. For a Prestwick home, apply and receive the written offer before the installation date is fixed.
There is no VAT on installing a heat pump anywhere in the UK, Scotland included, until 31 March 2027. Scottish permitted development rules and building standards apply, and the surveyor checks the unit position and any listed or conservation-area constraints.

How long is the heating season in Prestwick?
On the shortest day Prestwick gets only about 7 hours 04 minutes of daylight, with the sun around 11° up at noon. Long Scottish winters mean the heat pump runs for much of the year, so careful sizing, good controls and correctly sized radiators make a real difference.

Replacing an oil or LPG boiler with a heat pump in Prestwick: questions
Do I need new radiators for a heat pump in Prestwick?
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 Prestwick home gives a room-by-room list.
Can you service a heat pump in Prestwick that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Prestwick, whoever fitted them. Tell us the make and model when you book.
How soon can you survey a home in Prestwick?
Survey dates depend on how busy installers are in Ayrshire. We offer the next available dates when you enquire and confirm them in writing.
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.
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.
