Fire Compartmentation Surveys in London
Professional surveys across London and the UK ensuring compliance
At London Fire Block, we provide professional fire compartmentation surveys in London and across the UK, helping building owners and responsible persons ensure compliance with current fire safety legislation.
Compartmentation is the foundation of fire safety, designed to contain fire and smoke and protect escape routes. Our inspections identify breaches in fire-resisting construction and provide clear, actionable solutions.
All inspections are carried out by Level 3 qualified fire stopping inspectors with extensive frontline fire service experience.

Service risers and shafts

Visible compartment walls and floors

Inspecting hidden fire stopping
