Heat loss survey for Nairn homes
In Nairn, as anywhere in the UK, the heat pumps that perform well are the ones designed around low flow temperatures and sized from a proper heat loss calculation.
For Nairn homes with extensions or loft conversions, each part of the house is assessed on its own construction. Design outdoor temperatures for Nairn 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.
- Anyone getting a heat pump quote, as the first step
- Homes with an existing heat pump that seems undersized or expensive to run
- Landlords comparing properties before deciding where to switch first
What's included
- Outdoor unit siting options and noise check
- Electrical supply and network operator notes
- Radiator schedule with any upgrades needed for each room
- Room-by-room heat loss calculation using the MCS method
- Written results in your quote, or a stand-alone report if you order one
Houses in Nairn built in different eras can need very different heat pump sizes, which is why each is calculated room by room.
Grants and rules for heat pumps in Scotland
The Boiler Upgrade Scheme does not apply in Scotland. Instead, homeowners in Nairn 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.
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.
Heat loss survey costs around Nairn
The ranges below are typical installed prices for homes in the Highlands and Islands, including VAT. A survey sets the exact figure, because two similar-looking houses in Nairn can need quite different radiators and pipework.
| 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.
How long is the heating season in Nairn?
On the shortest day Nairn gets only about 6 hours 34 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.
The steps for heat loss surveys in Nairn

- A surveyor visits your Nairn home, measures every room and checks where the outdoor unit can go.
- You receive a heat loss design and a fixed written quote, with any grant shown where it applies.
- Installers fit the unit, cylinder and any radiator changes, typically over 2–4 days on site.
- The system is commissioned, set up with weather compensation and handed over with the paperwork.
Heat loss surveys in Nairn: questions
How long does a heat pump survey take in Nairn?
A home survey in Nairn 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.
How soon can you survey a home in Nairn?
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.
Where would the outdoor unit go on a Nairn 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 Nairn home.
How long does a heat loss survey take?
A typical survey takes 1–3 hours on site, depending on the size and complexity of the home. Larger or older houses with mixed construction, extensions or many rooms take longer. The calculations and design are completed afterwards, and the results are included in your quote or stand-alone report.
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.
