Heat loss survey for Cardigan homes
A heat pump suits most Cardigan homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
Houses in Cardigan built in different eras can need very different heat pump sizes, which is why each is calculated room by room. For Cardigan 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.
- Homeowners planning insulation or building work who want to know the effect on heat demand
- Homes with an existing heat pump that seems undersized or expensive to run
- Self-builders and architects who need emitter and system sizes early
What's included
- Room-by-room heat loss calculation using the MCS method
- Written results in your quote, or a stand-alone report if you order one
- Outdoor unit siting options and noise check
- Radiator schedule with any upgrades needed for each room
- Recommended heat pump size and design flow temperature
A surveyor visits your Cardigan home to measure each room, window and wall before any heat pump is sized.
Grants and rules for heat pumps in Wales
Homes in Cardigan 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 costs around Cardigan
These are guide prices for Dyfed, installed and including VAT. Your final price is fixed in a written quote after the survey and depends on the heat loss of the house, the radiators that need changing and where the unit goes.

|---|---|
| Home survey and heat loss calculation with an installation quote | Free |
| Stand-alone heat loss survey and report | £150–£400 |
Inc VAT. A stand-alone report is for homeowners who want the design without an installation quote.
Short winter days in Cardigan and what they mean
Cardigan has about 7 hours 44 minutes of daylight at midwinter and 16 hours 45 minutes at midsummer. That swing matters if you pair a heat pump with solar panels: summer generation can cover much of the hot water, winter generation far less.

Heat loss surveys in Cardigan: questions
Do I need new radiators for a heat pump in Cardigan?
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 Cardigan home gives a room-by-room list.
What size heat pump does a Cardigan 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 Cardigan home.
Can you service a heat pump in Cardigan that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Cardigan, whoever fitted them. Tell us the make and model when you book.
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.
