What we look for in Belfast
Surveys in Belfast also cover the surrounding BT1 district and towns such as Castlereagh and Newtownabbey. Northern Ireland has many rendered and pebble-dashed homes, older solid-walled rural houses, and estates built by the Housing Executive.
Parts of County Antrim fall in the higher wind-driven rain exposure bands, especially coastal and upland sites, so render specification, movement joints and detailing at cills, verges and the base of the wall matter more than usual.
For commercial premises in Belfast, we programme the work around opening hours so the building can keep trading.

Northern Ireland: planning and regulations
Before quoting in Belfast, we check whether the property is listed or in a conservation area, which changes what needs planning permission in Northern Ireland.
Building control applies to insulation and major re-rendering in Northern Ireland, and the work is signed off by the council.
On taller buildings in Northern Ireland we specify non-combustible mineral wool systems and confirm the classification with building control, in line with Technical Booklet E.
Which system suits a commercial building?
The building's height, use (for example, residential or assembly use) and fire strategy shape the choice. Mineral wool systems are typical for multi-storey and public buildings; EPS may suit single-storey units. The system manufacturer's classification is confirmed in writing.

Commercial EWI in Belfast: questions
Do you provide a maintenance plan?
Yes — the handover includes the system documents and recommended inspection and cleaning intervals.
Can the building stay open during the works?
Usually, yes. The work is phased and the scaffold layout keeps entrances and escape routes clear.
Is VAT 0% on commercial insulation?
Usually not. The zero rate covers insulation installed in residential accommodation and, since 1 February 2024, buildings used solely for a relevant charitable purpose, such as many charity-run village halls. Other commercial work is standard-rated.
Do you cover Belfast?
Yes — we survey and quote commercial external wall insulation in Belfast (BT1) and nearby Castlereagh, Newtownabbey and Holywood, with a fixed written price before any work starts.
