Powys: walls, weather and approvals
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.
Two-tone schemes, such as a darker plinth or entrance surround, are an option on houses in Powys.

Wales: planning and regulations
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.
What texture will it have?
Thin-coat renders come in grain sizes, typically 1–2mm. A 1.5mm grain is a common middle ground: fine enough to look smooth from the street, coarse enough to hide minor imperfections.

Insulated render in Powys: questions
Can insulated render be applied in winter?
Only in suitable weather — typically above 5°C and rising, with no frost or rain during curing. Winter programmes allow for lost days.
How long does insulated render last?
Typically 25–30 years or more with maintenance; the manufacturer's documentation sets the service life for the specific system.
Will my house look different?
Yes, if it was brick or pebble dash. If you want to keep a brick look, a brick-slip finish over the insulation is an option.
Do you cover all of Powys?
Yes. We survey and quote insulated render across Powys, including Newtown, Brecon, Welshpool, Llandrindod Wells.
