Before you book: heat loss surveys in Rothesay
Most homes can run on a heat pump if the system is designed properly, and Rothesay is no different. The key is matching the heat pump and radiators to the home's heat loss.
For Rothesay homes with extensions or loft conversions, each part of the house is assessed on its own construction. Design outdoor temperatures for Rothesay and the wider Argyll and Bute 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
- Anyone getting a heat pump quote, as the first step
- Landlords comparing properties before deciding where to switch first
What's included
- 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
- Radiator schedule with any upgrades needed for each room
- Hot water cylinder sizing for your household
Houses in Rothesay 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 Rothesay 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 Rothesay property at survey.

Winter daylight and heating in Rothesay

Heat loss surveys in Rothesay: questions
What size heat pump does a Rothesay 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 Rothesay home.
Do I need new radiators for a heat pump in Rothesay?
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 Rothesay home gives a room-by-room list.
How long does a heat pump survey take in Rothesay?
A home survey in Rothesay 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 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.
Is the heat loss survey free?
Yes, for installation enquiries the home survey and heat loss calculation are free, and the results form the basis of your written quote. If you only want the calculation and report, for example for building plans or comparing quotes, a stand-alone heat loss survey has a guide price of £150–£400, including VAT. We confirm which applies when you book.
