Heat loss survey for Kirkwall homes
In Kirkwall, 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.
The survey in Kirkwall includes a check of where the outdoor unit could sit and how its sound would reach neighbours. A surveyor visits your Kirkwall home to measure each room, window and wall before any heat pump is sized.
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
- 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
- Recommended heat pump size and design flow temperature
- Electrical supply and network operator notes
- Outdoor unit siting options and noise check
- Hot water cylinder sizing for your household
- Radiator schedule with any upgrades needed for each room
For Kirkwall homes with extensions or loft conversions, each part of the house is assessed on its own construction.
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 Kirkwall home, apply and receive the written offer before the installation date is fixed.
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 Kirkwall property at survey.
Heat loss survey prices in Kirkwall
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 Kirkwall 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.
Winter daylight and heating in Kirkwall
Kirkwall has about 6 hours 11 minutes of daylight at midwinter against 18 hours 30 minutes in midsummer. Heat pumps are designed to keep working well below freezing, but the design temperature for the survey is set for local conditions, not an average day.
How installation works in Kirkwall
- Send your postcode and a few details, or use the guide price tool.
- A surveyor visits your Kirkwall 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.
Kirkwall is in an area we cover by arrangement, so survey dates and any travel costs are confirmed individually in your quote.
Heat loss surveys in Kirkwall: questions
How long does a heat pump survey take in Kirkwall?
A home survey in Kirkwall 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 installation take in Kirkwall?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Kirkwall home states the expected time.
What size heat pump does a Kirkwall 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 Kirkwall home.
Will the survey check noise from the outdoor unit?
Yes. The surveyor identifies possible positions for the outdoor unit and carries out the MCS noise assessment, which estimates the sound level at the nearest neighbouring window from the unit's sound power level, distance and any barriers. In England, meeting the MCS planning standards is one of the conditions for permitted development. Wales, Scotland and Northern Ireland have their own rules, which we check.
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.
