Existing insulation and guarantee check for Didcot properties
Our Oxfordshire coverage takes in Didcot (OX11) and nearby Abingdon, Oxford and Witney. It is about 10 miles south of Oxford.
Buyers and sellers in Didcot often book this check when a survey report or EPC raises questions about the walls. The written result for your Didcot 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, if cavity wall insulation follows in Didcot, 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.
