Existing insulation and guarantee check for Luton properties

Our Bedfordshire coverage takes in Luton (LU1) and nearby Dunstable, Leighton Buzzard and Ampthill. It is around 18 miles south of Bedford.

The written result for your Luton property is plain English: what we found, what it means and what, if anything, to do next. Every inspection point in Luton is photographed and logged, so you have a record to show a buyer, lender or contractor.

Before any material is chosen, exposure is checked. Much of Bedfordshire 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 Luton, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

How to tell if a house already has cavity insulation

Look for a regular pattern of small patched holes in the mortar joints, often about a metre apart. Check the EPC, which may say 'filled cavity'. Ask the seller for a guarantee. The reliable answer is a borescope check, because patched holes can be from a fill that was later removed and EPCs are sometimes wrong.
