Cavity wall suitability survey across Somerset

We cover 10 towns in Somerset, including Bath, Weston-super-Mare, Taunton, Yeovil, Bridgwater and more.

Before any material is chosen, exposure is checked. Somerset 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 Somerset property is plain English: what we found, what it means and what, if anything, to do next. Where a Somerset wall shows cold patches or damp, the survey targets those areas first rather than sampling at random.

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.

Yes. We cover 10 towns across Somerset, including Bath, Weston-super-Mare, Taunton and Yeovil, and the villages around them. Island and remote addresses are surveyed by arrangement.

Which building regulations route applies in Somerset?

Somerset is in England, so filling a cavity is notifiable building work and needs a building notice or competent-person self-certification. We confirm the route in writing on your quote.

Yes when it is for an install quote. Standalone reports for Somerset buyers, sellers or landlords who do not need an install quote are priced before you book.

No. We only come out when you have asked us to. If someone cold-calls offering free insulation, check before you agree to anything.
