Before we quote in Chippenham
We also cover Trowbridge and Bath, close to Chippenham. 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.
On mixed-tenure blocks in Chippenham, we agree access and resident notices with the managing agent before scaffold goes up.

Planning and building control in England
Planning in Chippenham follows England's national rules: similar-looking finishes on houses are usually permitted, while flats, commercial premises, conservation areas and streets under an Article 4 direction need an application.
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.
What fire-safety rules apply?
For blocks with a storey 11 metres or more above ground, guidance points to external wall materials of limited combustibility, and combustible materials are banned in the external walls of relevant buildings 18 metres and over in England. Higher-risk buildings (18 metres or seven storeys and above, with at least two homes) go through the Building Safety Regulator. We specify non-combustible systems wherever these apply and tell you at enquiry stage if a building is outside our scope.

Flats and blocks in Chippenham: questions
Who pays for EWI on a leasehold block?
In England and Wales, usually the leaseholders through the service charge, depending on the lease, and the landlord must follow the Section 20 consultation process for major works.
Do flats need planning permission for EWI?
Yes. Permitted development rights for external alterations apply to houses, not flats or maisonettes, so an application is needed.
Can one flat have external wall insulation on its own?
Rarely. The outside walls are usually owned by the freeholder, the result would look patchy, and planning is unlikely. Whole-building schemes are the norm.
Do you cover Chippenham?
Yes — we survey and quote EWI for flats and blocks in Chippenham (SN15) and nearby Trowbridge, Bath and Chipping Sodbury, with a fixed written price before any work starts.
