Asbestos Survey Calculator
Estimate the number of samples, survey duration, and lab analysis costs for a management or refurbishment & demolition asbestos survey in the UK.
Management = non-intrusive; R&D = fully intrusive (required before demolition)

How We Calculate This
This calculator estimates the number of bulk samples required for an asbestos survey based on property type, age, and survey scope per HSG264 guidance published by the Health and Safety Executive.
How the estimate is calculated
Step 1: A base sample count is assigned from property type and survey type. R&D surveys require roughly double the samples of management surveys.
Step 2: An age multiplier adjusts for asbestos prevalence — properties from the 1950-1985 peak period have the highest multiplier (up to 1.5x).
Step 3: Additional floors increase the count by approximately 30% per floor above ground.
Step 4: Lab analysis cost is calculated by multiplying the sample count by the cost per sample (typically £15-£30 through a UKAS-accredited laboratory).
UK regulations
Asbestos surveys must comply with the Control of Asbestos Regulations 2012 (CAR 2012) and follow HSG264 guidance. Surveyors should hold BOHS P402 (management) or P403 (R&D) qualifications and work through a UKAS-accredited organisation.
