Heat loss survey for Risca homes
Most homes can run on a heat pump if the system is designed properly, and Risca is no different. The key is matching the heat pump and radiators to the home's heat loss.
A surveyor visits your Risca home to measure each room, window and wall before any heat pump is sized. Houses in Risca built in different eras can need very different heat pump sizes, which is why each is calculated room by room.
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
- Self-builders and architects who need emitter and system sizes early
- Anyone getting a heat pump quote, as the first step
What's included
- Radiator schedule with any upgrades needed for each room
- Room-by-room heat loss calculation using the MCS method
- Electrical supply and network operator notes
- Written results in your quote, or a stand-alone report if you order one
- Outdoor unit siting options and noise check
Homeowners in Risca thinking about insulation work can use the survey to see how it would change their heat pump size.
Grants and rules for heat pumps in Wales
In Wales the Boiler Upgrade Scheme gives £7,500 towards an air source heat pump (£9,000 if it replaces oil or LPG, from 21 July 2026 to 31 March 2027; £2,500 for air-to-air). The MCS-certified installer named in your quote applies to Ofgem for you, and the grant comes off your Risca quote.
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 Risca
Guide prices for Risca and the rest of Gwent are shown below, installed and inc VAT. We publish ranges rather than a single figure because design details move the price, and the written quote after survey fixes it.
| Survey | Guide price |
|---|---|
| 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.
Designing for Risca's winters
Risca has about 7 hours 48 minutes of daylight at midwinter and 16 hours 40 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 Risca: questions
How long does a heat pump survey take in Risca?
A home survey in Risca 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 you cover Newport (Gwent) as well as Risca?
Yes. We arrange surveys and installation in Newport (Gwent), which is about 5 miles east of Risca, and across Gwent.
How long does installation take in Risca?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Risca home states the expected time.
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.
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.
