Party wall cavity insulation for Ampthill properties
Our Bedfordshire coverage takes in Ampthill (MK45) and nearby Bedford, Dunstable and Leighton Buzzard. It is about 7 miles south of Bedford.
Most Ampthill houses built from the 1920s onwards have cavity walls, but the survey still checks each one: cavity width, debris, the condition of the brickwork and how exposed each wall is. If a wall in Ampthill is not suitable, for example because of an undiagnosed damp patch or a very exposed gable, you are told so in writing with the reason.
Exposure matters for every cavity wall. 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.
On the rules side, in Ampthill filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
Funding in England

What we need from you and your neighbour
The cavity is shared, so we talk you through notifying your neighbour before work. Filling is done from your side, usually through the loft. The survey confirms the wall is a cavity wall and not solid masonry, and checks for cables, flues and any gaps that would let fill escape.
