Air source heat pump installation in Westhill: what to expect
The question for a Westhill 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.
Many homes in Westhill have a side passage or rear garden with room for an outdoor unit, and the survey checks airflow and distance from neighbouring windows. For older properties in Westhill, the heat loss calculation looks closely at solid walls, single glazing and draughts before any unit is sized.
We survey your home, design a heat pump system around its real heat loss, and manage the installation from the first visit to the MCS certificate.
- Homes replacing a gas, oil, LPG or electric heating system
- Owners who want one contract covering design, fitting and paperwork
- Households with room for a hot water cylinder
What's included
- System design, unit sizing and a written quote
- Removal of the old boiler or heaters
- Radiator and pipework changes where the design needs them
- Commissioning, handover and a walk-through of the controls
- Free home survey and room-by-room heat loss calculation
Installers working in Westhill plan the order of work so heating and hot water are off for as short a time as practical.
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 Westhill 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.

Winter daylight and heating in Westhill
On the shortest day Westhill gets only about 6 hours 40 minutes of daylight, with the sun around 9° 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.

Air source heat pump installation in Westhill: questions
What size heat pump does a Westhill 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 Westhill home.
How long does installation take in Westhill?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Westhill home states the expected time.
Where would the outdoor unit go on a Westhill 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 Westhill home.
Do I need new radiators for a heat pump?
Not always; many homes keep most of their radiators and change only a few. Because a heat pump runs at a lower water temperature than a boiler, each radiator gives out less heat, so the survey checks every room against its heat loss. Rooms where the existing radiator falls short get a larger one, with a guide price of £250–£450 each, installed and including VAT.
How long does an air source heat pump installation take?
A typical home installation takes 2–4 days on site. It takes longer if several radiators are being replaced, pipework is being upgraded or the cylinder is going in a new location. Your quote sets out the expected programme, including when you will be without heating and hot water. Timings are typical rather than fixed, because older homes sometimes reveal surprises once floorboards are lifted.
