Existing insulation and guarantee check for Wellingborough properties

Wellingborough sits in Northamptonshire, around 9 miles north-east of Northampton. We work across the NN8 district, including nearby Rushden, Kettering and Northampton.

A survey in Wellingborough 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 Wellingborough property is plain English: what we found, what it means and what, if anything, to do next.

Exposure matters for every cavity wall. Much of Northamptonshire 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.

In terms of approvals, if cavity wall insulation follows in Wellingborough, 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.

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.
