Before you book: heat loss surveys in Tonypandy
Homes around Tonypandy range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
For Tonypandy homes with extensions or loft conversions, each part of the house is assessed on its own construction. The survey in Tonypandy 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.
- Landlords comparing properties before deciding where to switch first
- Self-builders and architects who need emitter and system sizes early
- Anyone getting a heat pump quote, as the first step
What's included
- Hot water cylinder sizing for your household
- Outdoor unit siting options and noise check
- 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
A surveyor visits your Tonypandy home to measure each room, window and wall before any heat pump is sized.
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 Tonypandy 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 costs around Tonypandy
The ranges below are typical installed prices for homes in Mid Glamorgan, including VAT. A survey sets the exact figure, because two similar-looking houses in Tonypandy can need quite different radiators and pipework.
| 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 Tonypandy's winters
Tonypandy 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 Tonypandy: questions
Do you cover Pontypridd as well as Tonypandy?
Yes. We arrange surveys and installation in Pontypridd, which is about 5 miles east of Tonypandy, and across Mid Glamorgan.
How long does installation take in Tonypandy?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Tonypandy home states the expected time.
How soon can you survey a home in Tonypandy?
Survey dates depend on how busy installers are in Mid Glamorgan. We offer the next available dates when you enquire and confirm them in writing.
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.
What is a design flow temperature?
The design flow temperature is the temperature of the water sent to your radiators or underfloor heating on the coldest design day. Heat pumps are more efficient at lower flow temperatures, typically around 35–50°C. Choosing it is a balance: a lower figure improves efficiency but can mean larger radiators in some rooms, so the design shows both.
