What to know about heat loss surveys in Perth
Every property in Perth is different, so the design starts from measurements rather than a rule of thumb. That keeps the system the right size and the running costs predictable.
For Perth homes with extensions or loft conversions, each part of the house is assessed on its own construction. Homeowners in Perth thinking about insulation work can use the survey to see how it would change their heat pump size.
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
- Anyone getting a heat pump quote, as the first step
- Homes with an existing heat pump that seems undersized or expensive to run
What's included
- Outdoor unit siting options and noise check
- Written results in your quote, or a stand-alone report if you order one
- Radiator schedule with any upgrades needed for each room
- Electrical supply and network operator notes
- Recommended heat pump size and design flow temperature
A surveyor visits your Perth 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 Perth 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 Perth property at survey.
Guide prices for heat loss surveys in Perth
These are guide prices for Perth and Kinross, 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.

| Stand-alone heat loss survey and report | £150–£400 |
Inc VAT. A stand-alone report is for homeowners who want the design without an installation quote.
How long is the heating season in Perth?
On the shortest day Perth gets only about 6 hours 51 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.

Heat loss surveys in Perth: questions
Can you service a heat pump in Perth that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Perth, whoever fitted them. Tell us the make and model when you book.
How long does installation take in Perth?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Perth home states the expected time.
Do I need new radiators for a heat pump in Perth?
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 Perth home gives a room-by-room list.
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.
Can I use the heat loss report to get other quotes?
Yes. A stand-alone heat loss report is yours to use, including sharing it with other installers so their quotes are based on the same figures. Comparing quotes like for like makes it easier to see differences in equipment, radiator upgrades and workmanship terms. The report states the assumptions used wherever construction could not be confirmed.
