Heat load surveys and system design across Powys

No two rooms in Newtown gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing. For self-builds and extensions in Newtown, a standalone design pack can go straight to your builder. Humid summer spells in South Wales make dehumidifying and cooling equally welcome.

Prices in Powys

Guide prices around Powys run from £365 to £1,145 for a standalone design pack including VAT. That sits a little below the UK middle, reflecting typical South and Mid Wales labour rates.

Planning and permissions

In Wales, outdoor units of up to 1.5 m³ that meet MCS 020a noise limits are usually permitted development on houses; listed buildings need consent, and in conservation areas a unit cannot go on a wall or roof facing a road.

The survey

The free survey is where the real price is set: room measurements, pipe and drain routes, electrical checks and the outdoor unit position, all written into your quote. At the survey we look at how each room is used, where the sun hits it and how the pipes can reach the outside wall, then put it all in a written quote.
