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.
