Existing insulation and guarantee check for Corby properties
If your property is in Corby or the NN17 district or nearby Kettering, Market Harborough and Wellingborough, it is within our Northamptonshire coverage. It is around 19 miles north-east of Northampton.
The written result for your Corby property is plain English: what we found, what it means and what, if anything, to do next. Where a Corby wall shows cold patches or damp, the survey targets those areas first rather than sampling at random.
Every elevation is judged on its own exposure. 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.
As for paperwork, if cavity wall insulation follows in Corby, 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.
