Local considerations in Trowbridge
Surveys in Trowbridge also cover the surrounding BA14 district and towns such as Bath and Frome. It's roughly 25 miles from Trowbridge to Swindon, the largest town in Wiltshire. 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 Trowbridge, we agree access and resident notices with the managing agent before scaffold goes up.

England: planning and regulations
Before quoting in Trowbridge, we check whether the property is in a conservation area, under an Article 4 direction or listed, because that decides whether changing the outside needs planning permission.
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 Trowbridge: questions
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 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.
Do you work on high-rise buildings?
Tell us the height and number of storeys. Buildings in the higher-risk category have a separate regulatory route, and we'll say plainly if we're not the right contractor.
Do you cover Trowbridge?
Yes — we survey and quote EWI for flats and blocks in Trowbridge (BA14) and nearby Bath, Frome and Chippenham, with a fixed written price before any work starts.
