Bonded polystyrene bead insulation for Staines properties
Staines sits in Surrey, around 14 miles north of Guildford. We work across the TW18 district, including nearby Egham, Sunbury-on-Thames and Walton-on-Thames.
If a wall in Staines 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. Where a Staines property has an extension or a conservatory, we check how the old and new walls meet, because that junction is often missed.
Local weather affects which walls can be filled. Much of Surrey 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, in Staines 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.
What is included in Staines
