Before you book: heat loss surveys in Lerwick
Most homes can run on a heat pump if the system is designed properly, and Lerwick is no different. The key is matching the heat pump and radiators to the home's heat loss.
Houses in Lerwick built in different eras can need very different heat pump sizes, which is why each is calculated room by room. The survey in Lerwick includes a check of where the outdoor unit could sit and how its sound would reach neighbours.
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.
- Landlords comparing properties before deciding where to switch first
- Self-builders and architects who need emitter and system sizes early
- Homes with an existing heat pump that seems undersized or expensive to run
What's included
- Radiator schedule with any upgrades needed for each room
- Room-by-room heat loss calculation using the MCS method
- Outdoor unit siting options and noise check
- Hot water cylinder sizing for your household
- Electrical supply and network operator notes
For Lerwick 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 Lerwick home, apply and receive the written offer before the installation date is fixed.
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.

Winter daylight and heating in Lerwick
On the shortest day Lerwick gets only about 5 hours 49 minutes of daylight, with the sun around 6° 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.
How installation works in Lerwick
- Send your postcode and a few details, or use the guide price tool.
- A surveyor visits your Lerwick 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.
Lerwick 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 Lerwick: questions
How soon can you survey a home in Lerwick?
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.
How long does installation take in Lerwick?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Lerwick home states the expected time.
What size heat pump does a Lerwick 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 Lerwick home.
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.
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.
