What is a Compartmentation Survey?

A compartmentation survey is a detailed inspection of a building’s fire-resistant barriers. Our qualified surveyors assess whether walls, floors, ceilings, service risers, and fire doors are adequately constructed and maintained to prevent the passage of fire and smoke.

Why are Compartmentation Survey Important?

Fire compartmentation is a legal requirement under the Regulatory Reform (Fire Safety) Order 2005. Poorly installed or damaged fire-stopping measures can severely compromise a building’s safety. A survey ensures that: 

  • Fire and smoke cannot spread unchecked through hidden voids, service penetrations, or damaged barriers. 
  • Escape routes remain protected for the required evacuation time. 
  • The building complies with current legislation and British Standards.

 

Who Needs a Compartmentation Survey?

Compartmentation surveys are vital for: 

  • Residential buildings, particularly high-rise blocks and HMOs. 
  • Commercial properties such as offices, warehouses, and retail spaces. 
  • Public sector buildings including hospitals, schools, and government facilities. 

Responsible persons, such as landlords, building owners, and managing agents, are required to ensure that fire compartments are properly maintained.

What Does a Compartmentation Survey Involve?

Our surveyors carry out thorough inspections of: 

  • Walls, ceilings, and floors forming fire compartments. 
  • Fire stopping around service penetrations (cables, pipes, ductwork). 
  • Protected shafts and risers. 
  • Fire doors, glazing, and seals. 
  • Roof voids, lofts, and concealed cavities. 

We identify any breaches, damage, or non-compliance and provide clear recommendations for remedial works.

How Often Should Compartmentation Be Checked?

While the law requires that fire precautions are regularly maintained, best practice and British Standards (such as BS 9999) recommend periodic checks, particularly after refurbishments, alterations, or where damage may have occurred. Firntec can help establish an inspection schedule based on your building’s risk profile.

Following inspection, Firntec provides a detailed digital report with photographic evidence, compliance ratings, and a prioritised action plan.
