Gwent: walls, weather and approvals
South Wales has long runs of solid-wall valley terraces, Victorian and Edwardian town housing and post-war council estates.
Exposure to wind-driven rain varies across Gwent: sheltered town streets fare better than walls on high ground or facing the prevailing weather, and the render, beads and cill details are chosen with that in mind.
On brick terraces in Gwent, slips can insulate the wall while keeping the street's look.

Approvals 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.

Brick slip EWI in Gwent: questions
Is a brick slip finish more expensive?
Yes — roughly £70–£120 per m² more than render, because of materials and slower installation.
Do brick slips fall off?
Not when installed to the system manufacturer's specification, with the right adhesive, fixings and pointing.
Will brick slips match my neighbours' brick?
We source slips to get close in colour and texture and show samples beforehand, but an exact match to weathered brick isn't always possible.
Do you cover all of Gwent?
Yes. We survey and quote brick slip finishes across Gwent, including Newport (Gwent), Cwmbran, Pontypool, Ebbw Vale, Caerphilly.
