Heat loss survey for Caldicot homes
The question for a Caldicot home is rarely whether a heat pump can work, but what needs to change to make it work well: radiator sizes, pipework, controls and where the unit goes.
Design outdoor temperatures for Caldicot and the wider Gwent come from local cold-weather data, not a national average. The survey in Caldicot 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.
- 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
- Landlords comparing properties before deciding where to switch first
What's included
- Recommended heat pump size and design flow temperature
- Room-by-room heat loss calculation using the MCS method
- Outdoor unit siting options and noise check
- Written results in your quote, or a stand-alone report if you order one
- Electrical supply and network operator notes
Houses in Caldicot 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 Caldicot 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.

Designing for Caldicot's winters
On the shortest day Caldicot gets about 7 hours 49 minutes of daylight, and the winter sun reaches only around 15° above the horizon at noon. Winters this far south are milder than in most of the UK, which helps a heat pump run at low flow temperatures for much of the season.

Heat loss surveys in Caldicot: questions
How long does a heat pump survey take in Caldicot?
A home survey in Caldicot 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.
Do I need new radiators for a heat pump in Caldicot?
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 Caldicot home gives a room-by-room list.
How long does installation take in Caldicot?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Caldicot home states the expected time.
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.
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.
