Before you book: air source heat pump installation in Portlethen
A heat pump suits most Portlethen homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
Installers working in Portlethen plan the order of work so heating and hot water are off for as short a time as practical. Many homes in Portlethen have a side passage or rear garden with room for an outdoor unit, and the survey checks airflow and distance from neighbouring windows.
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
- Houses with reasonable insulation, or a plan to improve it
- Households with room for a hot water cylinder
What's included
- Free home survey and room-by-room heat loss calculation
- Removal of the old boiler or heaters
- Radiator and pipework changes where the design needs them
- Outdoor unit, hot water cylinder and weather compensation controls
- MCS registration and certificate, plus network operator notification
For older properties in Portlethen, the heat loss calculation looks closely at solid walls, single glazing and draughts before any unit is sized.
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 Portlethen 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.

Air source heat pump installation in Portlethen: questions
Do I need new radiators for a heat pump in Portlethen?
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 Portlethen home gives a room-by-room list.
Where would the outdoor unit go on a Portlethen 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 Portlethen home.
How long does a heat pump survey take in Portlethen?
A home survey in Portlethen 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.
Will an air source heat pump be noisy?
Heat pumps are designed to run quietly, but where the unit sits makes a real difference. The survey looks for a position away from bedroom windows and neighbours, with clear airflow, and the installation must pass the MCS noise assessment. The fan is most noticeable on very cold days when the unit works hardest, and a little vapour during the periodic defrost is normal.
What grants can I get for a heat pump?
It depends on where you live. In England and Wales the Boiler Upgrade Scheme gives £7,500 towards an air-to-water heat pump, which the installer claims and deducts from your quote. In Scotland, Home Energy Scotland offers a grant of up to £7,500, with up to £1,500 more for eligible rural and island homes, but you need a written funding offer before work starts. Northern Ireland has no dedicated homeowner heat pump grant at present.
