What to know about heat loss surveys in Knighton
In Knighton, as anywhere in the UK, the heat pumps that perform well are the ones designed around low flow temperatures and sized from a proper heat loss calculation.
Design outdoor temperatures for Knighton and the wider Powys come from local cold-weather data, not a national average. Houses in Knighton 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.
- Self-builders and architects who need emitter and system sizes early
- 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
What's included
- Radiator schedule with any upgrades needed for each room
- 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
For Knighton homes with extensions or loft conversions, each part of the house is assessed on its own construction.
Grants and rules for heat pumps in Wales
Homes in Knighton 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.

Heat loss surveys in Knighton: questions
Where would the outdoor unit go on a Knighton 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 Knighton home.
Do you cover Newtown as well as Knighton?
Yes. We arrange surveys and installation in Newtown, which is about 16 miles north-west of Knighton, and across Powys.
How long does installation take in Knighton?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Knighton 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.
Will the survey check noise from the outdoor unit?
Yes. The surveyor identifies possible positions for the outdoor unit and carries out the MCS noise assessment, which estimates the sound level at the nearest neighbouring window from the unit's sound power level, distance and any barriers. In England, meeting the MCS planning standards is one of the conditions for permitted development. Wales, Scotland and Northern Ireland have their own rules, which we check.
