Existing insulation and guarantee check for Tewkesbury properties
Our Gloucestershire coverage takes in Tewkesbury (GL20) and nearby Cheltenham, Gloucester and Stroud. It is about 9 miles north of Gloucester.
Buyers and sellers in Tewkesbury often book this check when a survey report or EPC raises questions about the walls. A survey in Tewkesbury gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound.
Wind-driven rain is the first thing the surveyor weighs up. Gloucestershire 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 Tewkesbury, 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.
