Cavity wall suitability survey for Farnworth properties
We cover Farnworth and the BL4 postcode district, including nearby Walkden, Bolton and Radcliffe. It is roughly 8 miles north-west of Manchester.
Buyers and sellers in Farnworth often book this check when a survey report or EPC raises questions about the walls. Every inspection point in Farnworth is photographed and logged, so you have a record to show a buyer, lender or contractor.
Local weather affects which walls can be filled. Greater Manchester 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 Farnworth filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
Rules in England
Filling a cavity is notifiable building work and needs a building notice or competent-person self-certification if insulation work follows.

Wall construction and thickness at window reveals; cavity width and debris with a borescope; brickwork, pointing, render, sills, gutters and downpipes; signs of damp inside and out; air bricks and flues; joins with neighbours and extensions; and the exposure of each elevation to wind-driven rain.
