What we look for in Chippenham
As well as Chippenham itself, we quote in Trowbridge, Bath and Chipping Sodbury. Chippenham is about 16 miles from Swindon. The South West has many stone and solid-walled cottages, exposed coastal properties and a share of post-war system-built houses, including types such as the Cornish Unit.
Exposure to wind-driven rain varies across Wiltshire: 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.
For commercial premises in Chippenham, we programme the work around opening hours so the building can keep trading.

Approvals in England
For a house in Chippenham, external insulation or render is often permitted development if it looks similar to the existing walls; conservation areas, flats, commercial buildings and listed buildings need permission or consent, so we check your address first.
Insulating or re-rendering more than half of a wall's area brings in Part L of the Building Regulations, so building control is notified and the wall is upgraded to about 0.30 W/m²K where practical.
On residential buildings with a storey 11 metres or more above ground, guidance points to non-combustible external wall materials, and combustible materials are banned in relevant buildings 18 metres and over, so we specify mineral wool systems there.
Does commercial EWI need planning permission?
Generally yes — permitted development rights for external wall changes are written for houses. Applications need elevations showing the projection, finish and colours, and details at eaves and openings.

Commercial EWI in Chippenham: questions
Do you handle the planning application?
We provide the technical information, drawings and samples an application needs; your agent or our designer can submit it.
Is VAT 0% on commercial insulation?
Usually not. The zero rate covers insulation installed in residential accommodation and, since 1 February 2024, buildings used solely for a relevant charitable purpose, such as many charity-run village halls. Other commercial work is standard-rated.
Can the building stay open during the works?
Usually, yes. The work is phased and the scaffold layout keeps entrances and escape routes clear.
Do you cover Chippenham?
Yes — we survey and quote commercial external wall insulation in Chippenham (SN15) and nearby Trowbridge, Bath and Chipping Sodbury, with a fixed written price before any work starts.
