Brick slip EWI in Newport, Gwent: questions

Do I need planning permission for external wall insulation in Newport in Gwent?

Welsh guidance allows cladding a house without an application if the materials look similar to the original, but external wall insulation that projects more than 16cm from the wall needs planning permission. Any cladding or render in a conservation area, National Park, AONB or World Heritage Site needs permission, listed buildings need consent, and permitted development rights may have been removed by condition or Article 4 direction.

Not on installing insulation in a home at the moment: that's zero-rated until 31 March 2027, after which the rate is due to be 5%. Work on commercial buildings is standard-rated.

Which EWI system suits homes in Newport in Gwent?

It depends on the walls. Most brick houses in Newport in Gwent suit EPS with silicone render; older stone or lime-built walls suit wood fibre or insulating lime render; and blocks need mineral wool. The free survey recommends one and explains why.
