What we look for in St Austell
Surveys in St Austell also cover the surrounding PL25 district and towns such as Bodmin and Truro. St Austell is about 21 miles from Redruth. 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.
Parts of Cornwall 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.
For blocks in St Austell, we start with height, storeys and the planning position, because those decide the system.

Planning and building control in England
Planning in St Austell 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.
If the work covers more than half of a wall, or a quarter of the building's whole envelope, it counts as renovating a thermal element, with a target of about 0.30 W/m²K where feasible.
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.
Who needs to agree to EWI on a block?
The freeholder or management company commissions the work, but leaseholders usually pay through the service charge. In England and Wales, major works above the statutory threshold trigger the Section 20 consultation process before a contract is placed. We provide the specification and pricing you need for that consultation.

Flats and blocks in St Austell: questions
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.
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 cover St Austell?
Yes — we survey and quote EWI for flats and blocks in St Austell (PL25) and nearby Bodmin, Truro and Newquay, with a fixed written price before any work starts.
