PAS 2035-19 Cavity Wall Survey (July 2023)

This PAS 2035-19 cavity wall survey template helps assess a property’s suitability for cavity wall insulation. It guides surveyors to record building age and type, heating systems, flues and combustion vents, and to document ventilation, background vents, and extraction fans. Capture cavity areas, average cavity depth, omitted sections, adjoining property status, and evidence via photos, borescope images, and DPC checks across each elevation. The checklist includes site access needs, scaffolding or ladder requirements, and a dynamic risk assessment covering tools, electricity, working at height, and site conditions. It supports compliance questions aligned to PAS 2035 and building regulations, and provides sections for installation checks. An optional loft insulation survey covers insulation depth, materials, services, and safety considerations.
