What to know about heat loss surveys in Tredegar
Every property in Tredegar 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.
For Tredegar homes with extensions or loft conversions, each part of the house is assessed on its own construction. Houses in Tredegar 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.
- Anyone getting a heat pump quote, as the first step
- Landlords comparing properties before deciding where to switch first
- Homeowners planning insulation or building work who want to know the effect on heat demand
What's included
- Room-by-room heat loss calculation using the MCS method
- Recommended heat pump size and design flow temperature
- Hot water cylinder sizing for your household
- Radiator schedule with any upgrades needed for each room
- Electrical supply and network operator notes
A surveyor visits your Tredegar 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 Tredegar quote.
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.

How long is the heating season in Tredegar?
Tredegar has about 7 hours 47 minutes of daylight at midwinter and 16 hours 41 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 Tredegar: questions
How soon can you survey a home in Tredegar?
Survey dates depend on how busy installers are in Gwent. We offer the next available dates when you enquire and confirm them in writing.
Can you service a heat pump in Tredegar that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Tredegar, whoever fitted them. Tell us the make and model when you book.
How long does a heat pump survey take in Tredegar?
A home survey in Tredegar 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.
Can I use the heat loss report to get other quotes?
Yes. A stand-alone heat loss report is yours to use, including sharing it with other installers so their quotes are based on the same figures. Comparing quotes like for like makes it easier to see differences in equipment, radiator upgrades and workmanship terms. The report states the assumptions used wherever construction could not be confirmed.
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.
