Heat loss survey in Colwyn Bay: what to expect
A heat pump suits most Colwyn Bay homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
A surveyor visits your Colwyn Bay home to measure each room, window and wall before any heat pump is sized. Homeowners in Colwyn Bay 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
- Homeowners planning insulation or building work who want to know the effect on heat demand
What's included
- Written results in your quote, or a stand-alone report if you order one
- Electrical supply and network operator notes
- Room-by-room heat loss calculation using the MCS method
- Radiator schedule with any upgrades needed for each room
- Recommended heat pump size and design flow temperature
Houses in Colwyn Bay 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 Wales
Homes in Colwyn Bay can use the Boiler Upgrade Scheme, which applies in Wales as well as England: £7,500 towards an air source heat pump, or £9,000 when it replaces oil or LPG heating for installations from 21 July 2026 to 31 March 2027. The MCS-certified installer named in your quote applies and deducts the grant.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Wales has its own permitted development rules for air source heat pumps, so we check what applies to your property, including listed building and conservation-area constraints, at the survey.
Heat loss survey prices in Colwyn Bay

Heat loss surveys in Colwyn Bay: questions
How soon can you survey a home in Colwyn Bay?
Survey dates depend on how busy installers are in Clwyd. We offer the next available dates when you enquire and confirm them in writing.
How long does installation take in Colwyn Bay?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Colwyn Bay home states the expected time.
What size heat pump does a Colwyn Bay 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 Colwyn Bay 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.
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.
