Existing insulation and guarantee check for Salisbury properties
If your property is in Salisbury or the SP1 district or nearby Trowbridge, Chippenham and Swindon, it is within our Wiltshire coverage. It is around 34 miles south of Swindon.
Where a Salisbury wall shows cold patches or damp, the survey targets those areas first rather than sampling at random. Buyers and sellers in Salisbury often book this check when a survey report or EPC raises questions about the walls.
Wind-driven rain is the first thing the surveyor weighs up. Wiltshire has a mix of moderate and more exposed sites. Hilltop, coastal and west-facing walls take the brunt of wind-driven rain, so the survey records exposure for each elevation before a material is chosen.
In terms of approvals, if cavity wall insulation follows in Salisbury, 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.

How to tell if a house already has cavity insulation
Look for a regular pattern of small patched holes in the mortar joints, often about a metre apart. Check the EPC, which may say 'filled cavity'. Ask the seller for a guarantee. The reliable answer is a borescope check, because patched holes can be from a fill that was later removed and EPCs are sometimes wrong.
