Understanding fire risk assessment frequency is essential for maintaining compliance and protecting people within any building. Whether you manage small premises or large commercial buildings, knowing how often fire risk assessments should be reviewed helps reduce fire risk and ensure your fire safety approach remains effective. Many organisations now use fire risk assessment software to manage inspections, track changes and keep their fire risk assessment up to date across multiple sites.
Quick answer
If you’re asking how often should a fire risk assessment be carried out, the answer is:
- There is no exact timeframe set in UK law
- A review should take place at least annually
- It must be updated immediately after any significant changes
- Higher risk premises require more frequent review
This falls under the Regulatory Reform (Fire Safety) Order 2005, which makes it a legal requirement for the responsible person to ensure fire risk assessments are reviewed regularly.
What is a fire risk assessment?
A fire risk assessment is a structured assessment used to identify potential fire hazards, evaluate fire risk, and implement appropriate fire safety measures to reduce potential risks.
It typically involves:
- Identifying fire hazards such as ignition sources and flammable materials
- Assessing who may be at risk, including employees and visitors
- Reviewing fire detection systems, emergency lighting and fire extinguishers
- Evaluating escape routes and the emergency fire evacuation plan
This systematic evaluation ensures fire safety is maintained and helps protect lives within the building.
Is a fire risk assessment a legal requirement?
Yes, a fire risk assessment is a legal requirement for all non domestic premises in the UK.
The law states that:
- The responsible person must carry out a fire risk assessment
- Risk assessments be reviewed regularly
- The assessment must remain up to date
The responsible person could be a business owner, landlord or managing agent responsible for the premises.
Failure to comply can lead to enforcement action, particularly where fire safety measures are not sufficient to protect occupants.
Fire risk assessment frequency explained
A common question is how often fire risk assessment reviews are required.
There is no fixed fire risk assessment review period defined in legislation. Instead, the requirement is that the assessment reflects current conditions at all times.
General rule
- Carry out an annual review as a minimum
- Review immediately after any significant change
- Increase frequency in higher risk or complex premises
This is why the frequency of fire risk assessments varies depending on the building, its use and the level of fire risk present.
When should a fire risk assessment be reviewed?
Understanding when a fire risk assessment should be reviewed is critical for compliance.
1. After significant changes
A fire risk assessment review is required where the building has changed significantly.
Examples include:
- Structural alterations
- Work to undergo significant refurbishment
- Changes affecting escape routes or external walls
These changes can introduce new hazards and increase fire risk.
2. Changes in occupancy or use
Changes in staffing levels or building use can alter the overall fire risk.
Examples include:
- Increased employee numbers
- Changes in operational activity
- Different types of occupants
These changes can impact emergency fire evacuation procedures and safety planning.
3. Introduction of new equipment or materials
New machinery or flammable materials can introduce potential fire hazards.
This requires reassessing:
- Safe storage
- Ignition risks
- Control measures
4. After a fire or near miss
Any fire or near miss should trigger an immediate fire risk assessment review.
This helps ensure:
- New hazards are identified
- Controls are updated
- Future risk is reduced
5. Changes to fire safety systems
If fire detection, emergency lighting or fire extinguishers are updated, the assessment should reflect those changes.
How long does a fire risk assessment last?
Many people ask how long is a fire risk assessment valid for or how long does a fire risk assessment last.
There is no fixed expiry date.
However:
- It is only valid while accurate
- It may be no longer valid if conditions change
- It must be reviewed regularly to remain compliant
If a building or its use changes, a new fire risk assessment or review may be required.
What affects fire risk assessment frequency?
The fire risk assessment frequency depends on several factors.
Risk level
- Lower risk premises may require less frequent review
- Higher risk environments require closer monitoring
Building complexity
- Simple premises are easier to assess
- Complex premises require more frequent reviews
Activities within the building
- Equipment use increases fire risk
- Storage of flammable materials increases potential risks
Occupancy
- Higher footfall increases exposure
- Vulnerable occupants increase responsibility
Lower risk vs higher risk premises
Understanding the difference helps determine how often fire risk assessment reviews are needed.
Lower risk premises
- Offices
- Small retail units
- Buildings with minimal ignition sources
These typically require an annual review unless changes occur.
Higher risk premises
- Industrial buildings
- Sites with flammable materials
- Complex premises with multiple escape routes
These require more frequent fire risk assessment reviews.
Who should carry out the assessment?
The responsible person is accountable for ensuring the fire risk assessment is completed.
They may:
- Carry out the assessment themselves if they are a competent person
- Appoint a competent person internally
- Use a professional risk assessor for complex premises
For higher risk or commercial buildings, using a professional assessor helps ensure compliance with regulatory reform fire safety requirements.
What should a fire risk assessment review include?
A fire risk assessment review should confirm that fire safety measures remain effective.
This includes:
- Rechecking fire hazards and potential risks
- Reviewing escape routes
- Testing fire detection systems
- Checking emergency lighting
- Reviewing emergency plan effectiveness
- Updating significant findings
The aim is to risk evaluate whether controls still protect lives.
Keeping your fire risk assessment up to date
To keep your fire risk assessment regularly updated:
- Schedule an annual review
- Monitor for significant changes
- Keep documentation up to date
- Provide training review for employees
- Ensure emergency fire evacuation procedures remain effective
Using digital systems helps maintain consistency and compliance across multiple premises.
Using templates and systems for consistency
Consistency is essential when managing multiple risk assessments.
Using structured fire risk assessment templates helps ensure assessments follow a consistent format and capture all key details.
For broader compliance and ongoing monitoring, fire safety software supports inspections, reporting and maintaining fire safety standards across buildings.
Key takeaways
- Fire risk assessment frequency depends on risk and change, not a fixed timeframe
- An annual review is the baseline standard
- Reviews must happen after significant changes
- A fire risk assessment is only valid while accurate
- The responsible person is legally accountable
Final thoughts
If you’re asking how often should fire risk assessments be reviewed UK, the safest approach is to treat it as an ongoing process rather than a one-off task.
A fire risk assessment should evolve alongside your building, operations and risks. Regular review ensures fire safety measures remain effective, reduces potential risks and helps protect lives across all types of premises.
