Heat loss survey in Crickhowell: what to expect
Most homes can run on a heat pump if the system is designed properly, and Crickhowell is no different. The key is matching the heat pump and radiators to the home's heat loss.
For Crickhowell homes with extensions or loft conversions, each part of the house is assessed on its own construction. Houses in Crickhowell 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.
- Landlords comparing properties before deciding where to switch first
- Anyone getting a heat pump quote, as the first step
- Homeowners planning insulation or building work who want to know the effect on heat demand
What's included
- Outdoor unit siting options and noise check
- Hot water cylinder sizing for your household
- Written results in your quote, or a stand-alone report if you order one
- Radiator schedule with any upgrades needed for each room
- Electrical supply and network operator notes
Design outdoor temperatures for Crickhowell and the wider Powys come from local cold-weather data, not a national average.
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 Crickhowell 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.

Short winter days in Crickhowell and what they mean
Crickhowell has about 7 hours 46 minutes of daylight at midwinter and 16 hours 42 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 Crickhowell: questions
How long does installation take in Crickhowell?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Crickhowell home states the expected time.
Do I need new radiators for a heat pump in Crickhowell?
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 Crickhowell home gives a room-by-room list.
Where would the outdoor unit go on a Crickhowell house?
Usually at the side or rear, on a level base with space around it for airflow and servicing, away from bedroom windows where possible. The surveyor checks positions at your Crickhowell home.
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.
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.
