Heat loss survey for Cowbridge homes
Every property in Cowbridge is different, so the design starts from measurements rather than a rule of thumb. That keeps the system the right size and the running costs predictable.
Homeowners in Cowbridge thinking about insulation work can use the survey to see how it would change their heat pump size. For Cowbridge homes with extensions or loft conversions, each part of the house is assessed on its own construction.
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
- Homeowners planning insulation or building work who want to know the effect on heat demand
- Anyone getting a heat pump quote, as the first step
What's included
- Electrical supply and network operator notes
- Room-by-room heat loss calculation using the MCS method
- Hot water cylinder sizing for your household
- Radiator schedule with any upgrades needed for each room
- Recommended heat pump size and design flow temperature
Houses in Cowbridge 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 Cowbridge 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.
There is no VAT on installing a heat pump anywhere in the UK, Wales included, until 31 March 2027. Planning rules for heat pumps in Wales are set by the Welsh Government and differ from England's, so the surveyor checks the unit position against them.

Heat loss surveys in Cowbridge: questions
Do I need new radiators for a heat pump in Cowbridge?
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 Cowbridge home gives a room-by-room list.
How long does a heat pump survey take in Cowbridge?
A home survey in Cowbridge 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 Cowbridge?
Survey dates depend on how busy installers are in South Glamorgan. We offer the next available dates when you enquire and confirm them in writing.
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.
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.
