Heat load surveys and system design in Coleraine
No two rooms in Coleraine gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing. In Northern Ireland, cooling is mostly needed in conservatories and glazed rooms, while efficient heating benefits the whole home.
For self-builds and extensions in Coleraine, a standalone design pack can go straight to your builder. We cover Coleraine as part of County Londonderry, roughly 27 miles from Derry/Londonderry. Postcode districts we cover here include BT51 and BT52.
Prices in Coleraine
Budget around £365–£1,145 for a standalone design pack including VAT for heat load surveys and system design in and around Coleraine. It is a touch below the UK middle, as trade rates in Northern Ireland tend to be. Larger homes, more zones and full drawing sets for a builder are what move a design pack towards the upper figure. As an example, the Design pack option (drawings and schedules for one home) would typically be £365–£745 here.

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