Heat loss survey for Fort William homes
A heat pump suits most Fort William homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
The survey in Fort William includes a check of where the outdoor unit could sit and how its sound would reach neighbours. Design outdoor temperatures for Fort William and the wider the Highlands and Islands come from local cold-weather data, not a national average.
Every heat pump we quote starts with a room-by-room heat loss survey, free with installation enquiries and also available as a stand-alone report.
- Self-builders and architects who need emitter and system sizes early
- Homeowners planning insulation or building work who want to know the effect on heat demand
- Landlords comparing properties before deciding where to switch first
What's included
- Electrical supply and network operator notes
- Written results in your quote, or a stand-alone report if you order one
- Outdoor unit siting options and noise check
- Recommended heat pump size and design flow temperature
- Room-by-room heat loss calculation using the MCS method
A surveyor visits your Fort William home to measure each room, window and wall before any heat pump is sized.
Grants and rules for heat pumps in Scotland
The Boiler Upgrade Scheme does not apply in Scotland. Instead, homeowners in Fort William can apply to Home Energy Scotland for a grant of up to £7,500 towards a heat pump, with up to £1,500 more for eligible rural and island homes, plus an optional interest-free loan of up to £7,500. You need a written funding offer before any work starts.
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 Fort William property at survey.
Guide prices for heat loss surveys in Fort William
These are guide prices for the Highlands and Islands, installed and including VAT. Your final price is fixed in a written quote after the survey and depends on the heat loss of the house, the radiators that need changing and where the unit goes.
| Survey | Guide price |
|---|---|
| Home survey and heat loss calculation with an installation quote | Free |
| Stand-alone heat loss survey and report | £170–£450 |
Inc VAT. A stand-alone report is for homeowners who want the design without an installation quote.
Winter daylight and heating in Fort William
On the shortest day Fort William gets only about 6 hours 45 minutes of daylight, with the sun around 10° 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.

- We commission the heat pump, show you the controls and register the installation.
Heat loss surveys in Fort William: questions
Can you service a heat pump in Fort William that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Fort William, whoever fitted them. Tell us the make and model when you book.
Where would the outdoor unit go on a Fort William 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 Fort William home.
How soon can you survey a home in Fort William?
Survey dates depend on how busy installers are in the Highlands and Islands. We offer the next available dates when you enquire and confirm them in writing.
Why can't you size the heat pump from my boiler?
Boilers are often much larger than a home's real heat loss, because they are sized for fast hot water and quick warm-ups. Matching a heat pump to the boiler's output usually means an oversized unit that costs more and switches on and off too often. A room-by-room calculation finds the actual heat demand, which is what the heat pump needs to meet.
What is a design flow temperature?
The design flow temperature is the temperature of the water sent to your radiators or underfloor heating on the coldest design day. Heat pumps are more efficient at lower flow temperatures, typically around 35–50°C. Choosing it is a balance: a lower figure improves efficiency but can mean larger radiators in some rooms, so the design shows both.
