Homes and walls in Kent
Homes across the South East range from inter-war semis and post-war estates, which are mostly cavity-walled, to older solid-walled cottages and Victorian town terraces.
Much of Kent sits in the lower wind-driven rain exposure bands, which keeps the choice of finishes wide — though hilltop, coastal and exposed gable walls can still need a tougher specification, so we check the actual site.
On brick terraces in Kent, slips can insulate the wall while keeping the street's look.

Permissions in England
For houses, external wall insulation and render are often permitted development where the finish looks similar to the existing walls. Planning permission is usually needed in conservation areas, National Parks, National Landscapes, the Broads and World Heritage Sites (where cladding a house in stone, artificial stone, pebble dash, render, timber, plastic or tiles isn't permitted development), for flats and maisonettes, for commercial buildings, under an Article 4 direction, or where the look changes noticeably. Listed buildings need listed building consent.
Renovating more than half of a wall's area — insulating it, or stripping and re-rendering it — or more than a quarter of the building's whole external envelope brings in the energy requirements of Part L, so building control needs to be involved and the wall should reach about 0.30 W/m²K where that's technically, functionally and economically feasible.
How is the brick slip system built up?
Insulation boards are fixed as for any EWI, followed by a reinforced base coat. The slips are bonded with the system adhesive, spaced for joints, then pointed. Corners use L-shaped slips so the edge looks like a solid brick.

Brick slip EWI in Kent: questions
Is a brick slip finish more expensive?
Yes — roughly £70–£120 per m² more than render, because of materials and slower installation.
Can I mix brick slips and render?
Yes. A brick plinth or ground floor with render above is a common combination.
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 Kent?
Yes. We survey and quote brick slip finishes across Kent, including Maidstone, Gillingham, Chatham, Tunbridge Wells, Folkestone.
Do I need planning permission in England?
For houses, external wall insulation and render are often permitted development where the finish looks similar to the existing walls. We check your address before quoting.
