Heat load surveys and system design in Belfast
For self-builds and extensions in Belfast, a standalone design pack can go straight to your builder. Damp Northern Ireland winters make a heat pump's dehumidifying mode useful well beyond the summer.
Every Belfast quote starts with a room-by-room survey rather than a guess from floor area. Belfast is one of the main towns we cover in County Antrim, alongside Lisburn and Newtownabbey. Postcode districts we cover here include BT1, BT2, BT3, BT7, BT9 and 3 more.
Prices in Belfast
Budget around £365–£1,145 for a standalone design pack including VAT for heat load surveys and system design in and around Belfast. Labour rates in Northern Ireland 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. For reference, the Design pack option in Belfast (drawings and schedules for one home) usually comes to about £365–£745.
