We provide accurate building height surveys using professional surveying techniques to determine compliance with regulatory height thresholds under the Fire Safety (England) Regulations 2022 and Building Safety Act 2022. Our surveys measure from the lowest ground level adjoining the building exterior to the finished floor surface of the top occupied storey, excluding plant rooms and machinery areas, establishing whether buildings exceed the critical 11m threshold (requiring enhanced fire safety duties) or 18m/seven storey high-rise classification (mandating comprehensive regulatory obligations). Each survey includes detailed measurement documentation, storey counting analysis, mezzanine floor assessments, and regulatory compliance certification to support building classification, insurance requirements, and legal obligations for Responsible Persons and Accountable Persons.
