How Often do Fire Risk Assessments Need to be Reviewed?

Written by editor

As one of the most important elements of workplace fire safety, it is essential to have full confidence that your fire risk assessment is always up to date.

But how often should it be reviewed, and what types of changes might require an earlier reassessment?

This article explores these questions to help ensure you remain compliant with your legal responsibilities and maintain effective fire safety measures. To begin with, it is useful to revisit what a fire risk assessment is and why it is so important.

What is a fire risk assessment?

Fire risk assessments are a legal requirement for all commercial premises in the UK under the Regulatory Reform (Fire Safety) Order 2005.

A fire risk assessment involves a thorough review of your premises to identify potential fire hazards and assess the level of risk they pose. This includes examining sources of ignition, combustible materials and the overall layout of the building.

Once hazards have been identified, appropriate measures can be put in place to reduce or eliminate risk. This may include removing hazards, improving fire detection systems or installing suitable fire extinguishers.

It is also essential to identify individuals who may be particularly vulnerable in the event of a fire. This could include people with mobility issues, those working in high-risk areas, or individuals who are unfamiliar with the building.

Based on this assessment, you must develop an emergency plan and provide appropriate fire safety training to ensure all staff understand how to respond in the event of a fire.

How often should a fire risk assessment be reviewed?

The final stage of a fire risk assessment process is ongoing review. While the Fire Safety Order does not specify a fixed timeframe, it does require that assessments are kept up to date.

In practice, it is strongly recommended that fire risk assessments are reviewed at least once every 12 months following a full assessment. This ensures that any new hazards are identified and that existing safety measures and procedures remain effective.

 

In addition to annual reviews, a full reassessment is typically recommended every five years. However, in higher-risk environments, more frequent reassessments may be necessary.

When should a fire risk assessment be reviewed sooner?

The timeframes above should be considered minimum guidelines. To remain compliant with legal requirements, your fire risk assessment must always reflect current conditions within your premises.

 

This means that if circumstances change, you may need to review or update your assessment sooner than planned. Common triggers include:

1 Changes in legislation

Any updates to fire safety laws or regulations must be reviewed to ensure your premises remain compliant.

2 Changes in building use

If the purpose of your premises changes, this may introduce new fire risks and require updated safety measures.

3 Alterations to layout or structure

Changes to the layout can affect evacuation routes, emergency lighting and fire safety signage, all of which must be reassessed.

If new staff or occupants require additional support in an emergency, your evacuation plans must be updated accordingly.

Any of these changes may render your existing assessment out of date. Failing to review and update your fire safety measures not only puts people at risk, but may also result in non-compliance with legal obligations.

Fire risk assessments are not a one-off task, but an ongoing process that must evolve alongside your business. Regular reviews ensure that your safety measures remain effective and that you are prepared to respond appropriately in the event of a fire.
