Cavity wall suitability survey for Banbury properties
Our Oxfordshire coverage takes in Banbury (OX16) and nearby Bicester, Witney and Oxford. It is about 22 miles north of Oxford.
Where a Banbury wall shows cold patches or damp, the survey targets those areas first rather than sampling at random. The written result for your Banbury property is plain English: what we found, what it means and what, if anything, to do next.
Before any material is chosen, exposure is checked. Much of Oxfordshire 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.
For regulations, in Banbury 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.

Wall construction and thickness at window reveals; cavity width and debris with a borescope; brickwork, pointing, render, sills, gutters and downpipes; signs of damp inside and out; air bricks and flues; joins with neighbours and extensions; and the exposure of each elevation to wind-driven rain.
