Cavity wall work in Sunderland

Our Tyne and Wear coverage takes in Sunderland (SR1) and nearby Washington, Houghton-Le-Spring and Jarrow. It is roughly 11 miles south-east of Newcastle upon Tyne.

Wind-driven rain is the first thing the surveyor weighs up. Tyne and Wear 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.

As for paperwork, in Sunderland 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.
