Cavity wall suitability survey across Berkshire

We cover 11 towns in Berkshire, including Reading, Slough, Bracknell, Maidenhead, Wokingham and more.

Wind-driven rain is the first thing the surveyor weighs up. Much of Berkshire sits in the more sheltered driving-rain zones of the UK, which widens the choice of fill. Exposed elevations, coastal sites and high ground still get checked wall by wall.

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

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.

Cavity wall suitability survey in Berkshire: questions

Do you cover all of Berkshire?

Yes. We cover 11 towns across Berkshire, including Reading, Slough, Bracknell and Maidenhead, and the villages around them. Island and remote addresses are surveyed by arrangement.

Do you cold-call in Berkshire?

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

Is my Berkshire home too exposed for cavity insulation?

Much of Berkshire is in the more sheltered driving-rain zones, but exposed and coastal sites are still checked carefully. The survey records the exposure of each wall before recommending a material, or recommending against filling.

Which building regulations route applies in Berkshire?

Berkshire 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.
