Existing insulation and guarantee check for Swadlincote properties
Swadlincote sits in Derbyshire, about 11 miles south of Derby. We work across the DE11 district, including nearby Derby, Long Eaton and Ilkeston.
The written result for your Swadlincote property is plain English: what we found, what it means and what, if anything, to do next. Buyers and sellers in Swadlincote often book this check when a survey report or EPC raises questions about the walls.
Local weather affects which walls can be filled. Derbyshire 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 Swadlincote, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
Rules in England

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.
