Heat load surveys and system design in Gwent

Heat load surveys and system design across Gwent

For self-builds and extensions in Newport, a standalone design pack can go straight to your builder. Every Newport quote starts with a room-by-room survey rather than a guess from floor area. Wet South Wales winters make a heat pump's quiet, even heating and dehumidifying mode useful well beyond summer.

Prices in Gwent

For Gwent, 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. A standalone design pack is priced on the size of the home, the number of rooms and how much drawing work your builder or architect needs. For reference, the Design pack option in Gwent (drawings and schedules for one home) usually comes to about £365–£745.

Planning and permissions

Since 1 June 2026, Welsh permitted development rules for outdoor units closely match England's: up to 1.5 m³, two units on a detached home, one on other homes, and MCS 020a noise compliance. Listed buildings need consent, and conservation areas have extra restrictions on units facing a road.

The survey

We book surveys in Gwent at a time that suits you, including early evenings by arrangement, and send the written quote afterwards. On a survey in Gwent the engineer looks at room size, glazing, the route for pipes and drains, the electrics and where the outdoor unit can sit quietly, then the written quote follows.
