Existing insulation and guarantee check in Gloucestershire

For homes, landlords and businesses in Gloucestershire, an insulation and guarantee check comes with a clear price and a plain-English record. An existing insulation check tells you whether a cavity is filled, what with, whether it looks dry and intact, and how to trace any guarantee.

Exposure matters for every cavity wall. 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.

Every inspection point in Gloucestershire is photographed and logged, so you have a record to show a buyer, lender or contractor. A survey in Gloucestershire gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound.

Building Regulations in England

Filling an existing cavity wall is notifiable building work in England. Either a building notice goes to building control before the work, or the installer self-certifies it through a government-approved competent person scheme such as CIGA's CWISC scheme. The insulation used must also be suitable for the wall it goes into, which is why the survey checks construction, condition and exposure first.

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.
