Cavity Wall and Loft Insulation Survey

by Rob Mckenna, from the Community

Use this comprehensive survey template to investigate failed cavity wall insulation and assess loft insulation across domestic properties. It covers client inspection, pre-extraction, post-extraction, and revisit checks, with structured fields for tenure, property type and age, external finishes, structural condition, cavity depths, boroscope photos, and wall tie condition. Record internal damp, mould, condensation, ventilation, heating types, and safety monitors. Capture access constraints and remedial works, verify vents, flues, and guttering, and document asbestos confirmations. Includes a loft survey section and a dynamic risk assessment checklist.

Cavity Wall and Loft Insulation Survey PAS 2035
This PAS 2035 survey template guides assessors through cavity wall and loft insulation checks for domestic properties. Record address and tenure, building age and type, heating systems, flues and secondary heat sources. Document external condition, structural issues and ventilation, capture measurements and photos, and note damp, mould and condensation observations. Include cavity depth, vents and omissions, boroscope and DPC evidence, plus funding related ventilation questions. Use risk assessments for cavity and loft works and complete installation checks, materials used and signatures to verify compliant insulation.

Post Extraction and Cavity Wall Survey
This template supports post extraction and cavity wall surveys for residential and commercial properties. Inspect structural and external conditions, finishes, guttering, and access. Capture heating type, flue and chimney details, and verify safety monitors. Conduct boroscope checks, assess wall ties, confirm insulation removal, fit cavity brushes, and make good extraction holes. Check and document vents, trickle vents, and ventilation requirements per PAS 2035. Perform internal inspections for damp, condensation, and loft ingress, with photos and measurements of cavity depths across elevations. Includes dynamic risk assessment and installation checks to ensure suitability for reinstallation and occupant safety.

Cavity Wall and Loft Insulation Survey (PAS 2035)
This survey checklist guides assessments for cavity wall and loft insulation in line with PAS 2035:2019. Capture address and tenure, building and heating details, structural condition, evidence of damp and condensation, and ventilation types and performance. Document cavity depth, boroscope findings, DPC height, and internal heat-loss areas across elevations. Include access requirements, remedial works, quotations, and dynamic risk assessments for cavity and loft activities. Record loft specifics such as hatch size, existing and target insulation depths, services, obstructions, and materials. Conclude with installation checks and customer and crew signatures to verify pre and post installation compliance.

Pre-Extraction and Cavity Cleaning Survey
Use this structured survey to assess failed cavity wall insulation prior to extraction and cleaning. Record client and property details (type, age, floors, bedrooms, heating), external finishes and structural condition, internal damp and mould indicators, ventilation and fans, access needs, and remedial works. Capture cavity depths and omitted areas by elevation, add boroscope photos and drawings, and document materials present for removal. Include chimneys and flues locations, adjoining property status, risk controls, and a dynamic risk assessment and client declaration. Designed for Low Carbon Exchange Ltd and housing providers managing retrofit and insulation remediation.
