Local considerations in Powys
Mid Wales is largely rural, with stone farmhouses, cottages and market-town terraces, many of them solid-walled.
Parts of Powys 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.
On brick terraces in Powys, slips can insulate the wall while keeping the street's look.

Permissions in Wales
Permitted development rules for houses in Wales are similar to England's: a similar-appearance finish on a house is often permitted, while conservation areas, National Parks, Areas of Outstanding Natural Beauty, flats, commercial buildings and listed buildings need permission or consent. Your local planning authority has the final word.
The Building Regulations as they apply in Wales treat insulating or re-rendering more than half of a wall's area, or more than a quarter of the building's whole envelope, as renovating a thermal element, with Approved Document L (Wales) setting the target. Building control is involved before work starts.
Are brick slips real brick?
They can be — cut or manufactured clay slips — or concrete and flexible polymer slips designed to look like brick. Clay slips are heavier and need systems rated for that weight.

Not when installed to the system manufacturer's specification, with the right adhesive, fixings and pointing.
