Heat load surveys and system design in Newport, Gwent
For self-builds and extensions in Newport, a standalone design pack can go straight to your builder. Humid summer spells in South Wales make dehumidifying and cooling equally welcome.
Every Newport quote starts with a room-by-room survey rather than a guess from floor area. As well as Newport itself, our Gwent coverage takes in Cwmbran, Pontypool and the towns around them. Postcode districts we cover here include NP10, NP11, NP18, NP19 and NP20.
Prices in Newport, Gwent
For Newport, Gwent, expect roughly £365 to £1,145 for a standalone design pack, VAT included, adjusted for typical South and Mid Wales rates. Labour rates in South and Mid Wales keep this slightly under the national middle. Larger homes, more zones and full drawing sets for a builder are what move a design pack towards the upper figure.

Planning and permissions
Wales removed its old 3 m boundary rule on 1 June 2026, so most houses in Newport can now have an outdoor unit under permitted development if it meets the MCS 020a noise condition. Listed buildings still need consent, and conservation areas have extra restrictions.
The survey
We book surveys in Newport at a time that suits you, including early evenings by arrangement, and send the written quote afterwards. A survey in Newport usually takes one to two hours. We measure the rooms, check the walls and the consumer unit, agree the outdoor unit position with you and photograph the pipe routes.
