Existing insulation and guarantee check in Wiltshire

For homes, landlords and businesses in Wiltshire, 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.

Existing insulation and guarantee check across Wiltshire

We cover 4 towns in Wiltshire: Swindon, Salisbury, Trowbridge and Chippenham.

Before any material is chosen, exposure is checked. 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.

The written result for your Wiltshire property is plain English: what we found, what it means and what, if anything, to do next. Every inspection point in Wiltshire is photographed and logged, so you have a record to show a buyer, lender or contractor.

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.
