Heat load surveys and system design in Abergavenny
For self-builds and extensions in Abergavenny, a standalone design pack can go straight to your builder. Humid summer spells in South Wales make dehumidifying and cooling equally welcome.
Every Abergavenny quote starts with a room-by-room survey rather than a guess from floor area. Abergavenny lies roughly 16 miles from Newport, Gwent, and we cover it as part of Gwent. We cover NP7 and the streets around them.
Prices in Abergavenny
For Abergavenny, expect roughly £365 to £1,145 for a standalone design pack, VAT included, adjusted for typical South and Mid Wales rates. It is a touch below the UK middle, as trade rates in South and Mid Wales tend to be. The design pack price depends mainly on the number of rooms and whether full drawings and equipment schedules are needed. As an example, the Design pack option (drawings and schedules for one home) would typically be £365–£745 here.

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
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. 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.
