Existing insulation and guarantee check for St Austell properties
If your property is in St Austell or the PL25 district or nearby Bodmin, Truro and Newquay, it is within our Cornwall coverage. It is roughly 14 miles north-east of Truro.
Buyers and sellers in St Austell often book this check when a survey report or EPC raises questions about the walls. Where a St Austell wall shows cold patches or damp, the survey targets those areas first rather than sampling at random.
Before any material is chosen, exposure is checked. Parts of Cornwall face some of the heaviest wind-driven rain in the UK, especially exposed coastal and upland sites. Here the survey is stricter: some walls suit only certain certified systems, and some should not be filled at all.
On compliance, if cavity wall insulation follows in St Austell, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
Rules in England
Filling a cavity is notifiable building work and needs a building notice or competent-person self-certification if insulation work follows.

Tracing a guarantee
Many cavity fills carry a 25-year guarantee from the Cavity Insulation Guarantee Agency (CIGA). CIGA can confirm whether a property is covered and can issue a duplicate guarantee for a fee; at the time of writing that fee is £60 including VAT, and proof of ownership is required.
