Existing insulation and guarantee check for Coventry properties

Coventry sits in the West Midlands, around 17 miles east of Birmingham. We work across the CV1 district, including nearby Solihull, Sutton Coldfield and Birmingham.

Buyers and sellers in Coventry often book this check when a survey report or EPC raises questions about the walls. The written result for your Coventry property is plain English: what we found, what it means and what, if anything, to do next.

Exposure matters for every cavity wall. The West Midlands 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.

As for paperwork, if cavity wall insulation follows in Coventry, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

Rules in England

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.
