Homes and walls in County Antrim
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 blocks in County Antrim, we start with height, storeys and the planning position, because those decide the system.

Permissions in Northern Ireland
In Northern Ireland, permitted development is set by the Planning (General Permitted Development) Order (NI) 2015. Changing the external appearance of a house may need permission, and conservation areas, flats, commercial buildings and listed buildings need planning permission or listed building consent. Check with your council's planning office.
Insulating external walls is building work under the Building Regulations (Northern Ireland) 2012, handled by council building control, with Technical Booklet F1 covering conservation of fuel and power in dwellings.
Technical Booklet E sets the fire-safety guidance for external walls. On taller buildings we use non-combustible mineral wool systems and confirm the classification with building control.
For flats, the lease or management agreement sets how owners agree to the work and share its cost.
How disruptive is it for residents?
Most work happens from scaffolding outside. Residents may need to allow brief access to extend window cills, vents or flues from the inside. We provide a notice for residents covering dates, scaffold, and how to raise concerns.

Flats and blocks in County Antrim: questions
Can one flat have external wall insulation on its own?
Rarely. The outside walls are usually owned by the freeholder, the result would look patchy, and planning is unlikely. Whole-building schemes are the norm.
Do flats need planning permission for EWI?
Yes. Permitted development rights for external alterations apply to houses, not flats or maisonettes, so an application is needed.
Do you cover all of County Antrim?
Yes. We survey and quote EWI for flats and blocks across County Antrim, including Belfast, Lisburn, Newtownabbey, Carrickfergus, Ballymena.
Do I need planning permission in Northern Ireland?
In Northern Ireland, permitted development is set by the Planning (General Permitted Development) Order (NI) 2015. We check your address before quoting.
