How Often Should a Commercial Fire Risk Assessment Be Reviewed?
If you ask ten different property managers how often a commercial building needs a Fire Risk Assessment (FRA), nine of them will likely give you the same immediate answer: "Once a year."
While the "annual check" has become the default benchmark across the UK property sector, the actual legislation is far more nuanced. In fact, if you search the Regulatory Reform (Fire Safety) Order 2005 for the words "every 12 months," you won't find them.
Instead, the law states that the "Responsible Person" must review the fire risk assessment "regularly" to keep it up to date, and specifically when there is reason to suspect it is no longer valid or if there has been a significant change to the premises.
Operating on a strict, rigid 12-month calendar loop without accounting for real-world risk profiles can leave your building exposed. Here is a guide to understanding the true legal frequency of a commercial fire risk assessment review, how to determine your building’s risk category, and when you need to call in a specialist.
Re-Assessment vs. Review: What is the Difference?
Before diving into timelines, it is critical to understand the technical difference between a full fire risk assessment and an FRA review:
- A Full Fire Risk Assessment: This is a comprehensive, ground-up audit of the entire building fabric, active systems, electrical systems, and evacuation policies. It results in a brand-new, foundational safety document.
- A Fire Risk Assessment Review: This is a structured check of the existing FRA. The assessor reviews the original document against the current state of the building to ensure no new hazards have been introduced, previous action points have been resolved, and the physical environment matches the recorded data.
A review is less invasive than a full re-assessment, but it must still be conducted by a competent, certified professional to be considered legally robust.
Risk-Based Timelines: How Often Does Your Building Need a Review?
Under UK fire safety guidelines, the frequency of your reviews should be dictated by your building’s specific risk profile, occupancy type, and activities.
Here is a breakdown of how the industry determines how often to review FRA documents based on risk:
1. High-Risk Premises (Review Frequency: Every 12 Months or Sooner)
High-risk environments require constant vigilance. These are buildings where residents sleep, occupancy density is exceptionally high, or hazardous materials are processed.
- Property Types: HMOs, student accommodation blocks, care homes, hotels, and industrial sites (such as the diesel engine refurbishment garages we see across Leicester).
- The Schedule: A comprehensive commercial fire risk assessment review must be conducted at least every 12 months. For high-occupancy residential blocks, a full, new assessment is recommended every 2 to 3 years, with annual reviews in between.
2. Medium-Risk Premises (Review Frequency: Every 12 to 24 Months)
Medium-risk buildings typically house awake, alert occupants who are familiar with the layout and escape routes of the premises.
- Property Types: Standard commercial offices, retail shops, dentists, and light industrial warehouses.
- The Schedule: A professional review is recommended every 12 to 18 months. A brand-new, full FRA should be commissioned every 3 to 5 years, provided no major structural or operational changes occur.
3. Low-Risk Premises (Review Frequency: Every 24 to 36 Months)
Low-risk buildings are simple structures with low occupant numbers and minimal fire hazards.
- Property Types: Small, single-story offices, simple storage units, or low-use commercial spaces.
- The Schedule: A review every 2 years is generally sufficient, with a full re-assessment every 5 years. However, regular internal visual inspections by staff should still be logged weekly.
The "Trigger Events" That Bypass the Calendar
Even if your annual review is months away, certain operational shifts act as immediate legal triggers under the Fire Safety Order. You must commission an immediate review if any of the following occur:
- Structural or Layout Modifications: Adding a partition, altering escape corridors, or changing fire door installations.
- Changes to Building Use: Converting an office floor into a staff kitchen, or transitioning a commercial unit into a public-facing retail outlet.
- New Equipment or Storage: Installing heavy industrial machinery or storing large volumes of combustible materials.
- Vulnerable Occupants: Welcoming staff or residents with limited mobility or sensory impairments who require a Personal Emergency Evacuation Plan (PEEP).
- A Near-Miss or Fire Incident: Any event that tests your physical defences or evacuation plans.
Operating under an outdated assessment after any of these events instantly makes it an invalid fire risk assessment, which can void your commercial property insurance and lead to immediate prosecution if an incident occurs.
Why Certified Competency is Your Ultimate Defence
While the law allows a "competent person" to conduct internal reviews, the burden of proving that competency lies entirely on the shoulders of the Responsible Person.
During an industrial fire risk audit or local authority check, a fire officer will look closely at the credentials of the person who signed off on your safety strategy. If your review was handled by a general handyman or an untrained staff member, the authorities can reject your documentation.
Choosing a third-party accredited partner, such as a BAFE-certified assessor, is the gold standard of building protection. It provides the legal "shield" your business needs, proving to insurers, councils, and fire authorities that your safety strategy is backed by genuine, verified expertise.
