Heat loss survey in Welshpool: what to expect
A heat pump suits most Welshpool homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
The survey in Welshpool includes a check of where the outdoor unit could sit and how its sound would reach neighbours. A surveyor visits your Welshpool home to measure each room, window and wall before any heat pump is sized.
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
- Landlords comparing properties before deciding where to switch first
- Self-builders and architects who need emitter and system sizes early
What's included
- Electrical supply and network operator notes
- Outdoor unit siting options and noise check
- Radiator schedule with any upgrades needed for each room
- Room-by-room heat loss calculation using the MCS method
- Hot water cylinder sizing for your household
Design outdoor temperatures for Welshpool 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 Welshpool 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 Welshpool
The ranges below are typical installed prices for homes in Powys, including VAT. A survey sets the exact figure, because two similar-looking houses in Welshpool 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 Welshpool's winters
On the shortest day Welshpool gets about 7 hours 37 minutes of daylight, with the noon sun around 14° up. The heating season runs from autumn into spring, so a heat pump that is sized correctly and set up with weather compensation does most of its work in steady, cool conditions.

Heat loss surveys in Welshpool: questions
How soon can you survey a home in Welshpool?
Survey dates depend on how busy installers are in Powys. We offer the next available dates when you enquire and confirm them in writing.
Where would the outdoor unit go on a Welshpool 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 Welshpool home.
Do I need new radiators for a heat pump in Welshpool?
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 Welshpool home gives a room-by-room list.
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.
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.
