Heat load surveys and system design in Newtown
In South and Mid Wales, efficient heating is often as important as cooling. 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. We cover Newtown and the rest of Powys, including Brecon and Llandrindod Wells. We cover SY16 and the streets around them.
Prices in Newtown
Our South and Mid Wales guide price for heat load surveys and system design is £365–£1,145 for a standalone design pack, VAT included. It is a touch below the UK middle, as trade rates in South and Mid Wales tend to be. Larger homes, more zones and full drawing sets for a builder are what move a design pack towards the upper figure. Typical Design pack work (drawings and schedules for one home) lands around £365–£745 in this area.

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.

We book surveys in Newtown at a time that suits you, including early evenings by arrangement, and send the written quote afterwards.
