If you own a pre-2000 property and are planning any renovation work, you need an asbestos survey before works begin. This step-by-step guide explains exactly what the process involves — from booking to receiving your report.
Step 1: Decide Which Type of Survey You Need
A Management Survey is for properties that are occupied or in normal use. It identifies accessible asbestos-containing materials (ACMs) and assesses their condition. It does not involve destructive sampling and is suitable for properties where no immediate renovation is planned.
A Refurbishment and Demolition (R&D) Survey is required before any building works — kitchen or bathroom renovations, loft conversions, extensions, or any works that disturb the building fabric. It is more intrusive and will involve accessing wall cavities, floor voids and ceiling spaces.
Step 2: Find a UKAS-Accredited Surveyor
Always use a surveyor accredited by UKAS (United Kingdom Accreditation Service) with P402-qualified inspectors. UKAS accreditation means the company has been independently assessed against international standards for competence and impartiality. Do not use non-accredited companies — their reports may not be legally compliant.
Step 3: The Site Survey
The surveyor will visit the property and systematically inspect all accessible areas, looking for materials that may contain asbestos. Where suspect materials are found, the surveyor will take a small sample (typically a few grams) using specialist tools. Sampled areas are sealed and made good after sampling.
For a standard residential property, the inspection typically takes 1–3 hours. For large commercial properties, it may take a full day or more.
Step 4: Laboratory Analysis
Samples are sent to a UKAS-accredited laboratory for analysis using polarised light microscopy (PLM). This determines whether asbestos is present and, if so, which type (chrysotile, amosite, crocidolite). Results are typically available within 2–5 working days.
Step 5: The Report
The final report identifies all ACMs found, their location, condition, and an assessment of risk. For R&D surveys, it also identifies areas where destructive access would be required to complete the investigation. The report should be kept as part of the property’s records and shared with any contractors working on the property.
