Fire Risk Assessment London: High-Rise Rules

For businesses operating in the capital, arranging a fire risk assessment London is a critical legal duty. Under the Regulatory Reform (Fire Safety) Order 2005 (RRO), the designated Responsible Person must ensure that a thorough assessment of the premises is carried out. In a densely populated city like London, high-rise and multi-occupied buildings present unique hazards that require meticulous planning and a robust understanding of UK fire safety legislation.

Understanding Your Legal Duties in Multi-Occupied Buildings

The RRO applies to virtually all non-domestic premises, including the communal areas of multi-occupied residential buildings. If you own, manage, or operate a business within a high-rise structure, you share responsibility for maintaining a safe environment.

The Management of Health and Safety at Work Regulations 1999 (MHSWR) further reinforces the need to identify risks not only to employees but to anyone who may be affected by your business activities. In multi-occupied buildings, this means considering the actions of other tenants and the overall building management. The Responsible Person must ensure that:

  • Fire risks are identified and removed or reduced to as low as reasonably practicable.
  • Appropriate general fire precautions are in place.
  • A clear record of the significant findings is maintained.
  • Emergency routes and exits remain unobstructed at all times.

High-Rise Building Specifics

In London, high-rise buildings are defined under the RRO as those containing at least two residential floors, or where the top floor is 18 metres above ground level or seven storeys high. These structures demand heightened safety measures due to the complexity of evacuation and the rapid vertical spread of smoke and fire.

Under the Fire Safety Act 2021, the scope of the RRO was clarified to explicitly include the structure, external walls (including cladding and balconies), and flat entrance doors in high-rise buildings. The Responsible Person must ensure these elements are thoroughly evaluated during the assessment.

Key Considerations for London Premises

Conducting a fire risk assessment in a multi-occupied London building requires a comprehensive evaluation of shared spaces and structural integrity. The assessment should carefully address:

  • Communal Areas: Ensuring stairwells, corridors, and lobbies are free from combustible materials, such as stored rubbish, mobility scooters, or unauthorised furniture.
  • Flat Entrance Doors: Verifying that all doors opening into communal areas meet the required fire resistance standards and are fitted with appropriate self-closing mechanisms.
  • Evacuation Strategies: Confirming whether the building operates a simultaneous or stay-put evacuation policy, and ensuring that the fire detection and warning systems align with this strategy.
  • External Wall Systems: Assessing the materials used on the building's facade and ensuring they do not present an unacceptable risk of external fire spread.

The Importance of PAS 79 Methodology

To ensure a systematic and comprehensive evaluation, reputable fire safety professionals utilise recognised methodologies such as PAS 79. This publicly available specification provides a structured framework for conducting fire risk assessments, ensuring that no critical hazards are overlooked.

While PAS 79 is widely used as a best practice guide, it is essential to remember that the assessment itself must be suitable and sufficient for the specific complexities of your building. Given the structural complexities of high-rise premises, relying on a qualified professional is strongly advised.

Record Keeping and Ongoing Compliance

If your London business employs five or more people, or if your premises are subject to licensing, you are legally required to record the significant findings of your fire risk assessment. However, for high-rise and multi-occupied residential buildings, maintaining written records is mandatory regardless of employee numbers.

The Responsible Person must also ensure that the assessment is reviewed regularly. It should be updated promptly following any significant alteration to the building layout, a change in occupancy, or the introduction of new fire hazards. Routine reviews guarantee that your fire safety measures remain effective and compliant with the Health and Safety at Work etc. Act 1974 (HSWA) and the RRO.
