Existing insulation and guarantee check for Oxford properties
Oxford is among the towns we cover in Oxfordshire, alongside Abingdon, Didcot and Witney. Oxford is one of the main towns we cover in Oxfordshire.
A survey in Oxford gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound. The written result for your Oxford property is plain English: what we found, what it means and what, if anything, to do next.
Local weather affects which walls can be filled. 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, if cavity wall insulation follows in Oxford, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

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.
