Bonded polystyrene bead insulation for Brentwood properties
Brentwood sits in Essex, roughly 11 miles south-west of Chelmsford. We work across the CM14 district, including nearby Billericay, Basildon and South Ockendon.
Most Brentwood 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. A suitable wall in Brentwood is usually filled in a single day from outside, with drill holes made good to match the pointing.
Every elevation is judged on its own exposure. Much of Essex 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 compliance, in Brentwood filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
Funding in England
In England, ECO4 runs to 31 December 2026 and Warm Homes: Local Grant supports low-income households through councils.

What to know before you choose beads
Polystyrene is combustible, so beads are not the right choice for every building; height, use and nearby openings matter, and the system certificate sets the limits. PVC-sheathed cables in the cavity should be sleeved or kept out of contact with the beads where the certificate requires it. We check both at survey.
