Before you book: replacing an oil or LPG boiler with a heat pump in Alexandria
The question for an Alexandria 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.
If your home near Alexandria is off the mains gas grid, a heat pump removes the need for oil or LPG deliveries. Cottages and farmhouses in and around Alexandria 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.
- Older oil boilers nearing the end of their life
- Detached houses and bungalows with garden space for the unit
- Rural and village homes off the mains gas grid
What's included
- Oil tank draining and removal or making safe, as set out in your quote
- Free survey with a detailed heat loss calculation for older construction
- Outdoor unit, heat pump cylinder, controls and radiator changes
- Removal of the oil or LPG boiler and flue
- Help arranging LPG tank collection with your supplier
Rural properties near Alexandria usually have garden space for the outdoor unit, sited away from windows and sheltered where possible.
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 an Alexandria home, apply and receive the written offer before the installation date is fixed.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Scotland has its own permitted development rules for air source heat pumps and its own building standards, so we confirm what applies to your Alexandria property at survey.

Winter daylight and heating in Alexandria
On the shortest day Alexandria gets only about 6 hours 57 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 Alexandria: questions
Where would the outdoor unit go on an Alexandria 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 Alexandria home.
What size heat pump does an Alexandria 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 Alexandria home.
How long does a heat pump survey take in Alexandria?
A home survey in Alexandria usually takes one to two hours. The surveyor measures every heated room, checks windows, walls and radiators, and looks at where the outdoor unit and cylinder can go.
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.
Will I need bigger radiators in an older cottage or farmhouse?
Often in some rooms, because thick solid walls and older windows lose more heat, and heat pumps work at lower water temperatures than oil boilers. The survey checks each room. Rooms with high ceilings or large windows are common candidates for a larger radiator. Where swapping radiators is impractical, a high-temperature unit can be considered, with lower efficiency as the trade-off.
