Cavity insulation for new builds and extensions for Bathgate properties

If your property is in Bathgate or the EH48 district or nearby Livingston, Dalkeith and Musselburgh, it is within our Lothian coverage. It is around 5 miles west of Livingston.

Where a Bathgate property has an extension or a conservatory, we check how the old and new walls meet, because that junction is often missed. A suitable wall in Bathgate is usually filled in a single day from outside, with drill holes made good to match the pointing.

Before any material is chosen, exposure is checked. Lothian has a mix of moderate and more exposed sites. Hilltop, coastal and west-facing walls take the brunt of wind-driven rain, so the survey records exposure for each elevation before a material is chosen.

In terms of approvals, in Bathgate no building warrant is needed for insulation within a wall, but the work must meet the building standards.

Funding in Scotland

In Scotland, Home Energy Scotland is the route to the Home Energy Scotland Grant and Loan and Warmer Homes Scotland.

Extensions that join an older house

Where an extension meets an existing cavity wall, the junction is a weak point. We can borescope and fill the existing wall at the same time so the old and new walls perform together.
