Understanding Your Fire Risk Assessment Rating: What It Actually Means
Every Fire Risk Assessment ends with an overall risk rating — a single term that's meant to summarise the building's fire safety position. For a lot of property managers, that rating is the only part of a lengthy document they actually read closely. Understanding what it really means, and what it should trigger, matters more than the label itself.
The standard rating scale
Most Fire Risk Assessments in the UK follow a five-point scale, based on the likelihood of a fire occurring and the potential severity of harm to occupants:
Trivial risk — No action required beyond maintaining existing precautions. Genuinely rare for a commercial building of any real occupancy.
Tolerable risk — Risk is broadly acceptable; fire safety precautions are adequate, and only minor improvements (if any) are needed. This is the rating most well-managed commercial buildings should be aiming for.
Moderate risk — Efforts should be made to reduce risk within a reasonable timescale. Precautions are broadly in place but there are identifiable gaps that need addressing — this is a common finding, and not cause for alarm if there's a clear action plan attached.
Substantial risk — Risk needs to be reduced, and considerable importance should be attached to remedial action. This rating means real, identifiable shortfalls exist that could meaningfully affect occupant safety in a fire — action shouldn't be delayed.
Intolerable risk — Risk must be reduced, even if this means restricting or stopping use of all or part of the premises. This is rare, and typically reflects a serious, immediate danger to life — for example a building with no viable means of escape.
Where property managers go wrong
Treating "Tolerable" as "done." A Tolerable rating still usually comes with recommended actions. The rating describes the current level of risk, not a green light to ignore the report until next year.
Reading the rating without reading the action plan. The rating is a headline; the action plan is the substance. Two buildings can both be rated "Moderate" for entirely different reasons, with entirely different remedial priorities.
Assuming the rating alone protects you legally. If enforcement officers investigate after an incident, they'll look at whether the actions from the FRA were actually completed — not just what the rating said. A Moderate-rated FRA with unaddressed actions from eighteen months ago is a weaker position than a Substantial-rated one with a documented, in-progress action plan.
What should happen after you get your rating
Regardless of the overall rating, a competent FRA should give you:
A prioritised list of actions, typically categorised by urgency (immediate, short-term, medium-term)
Clear ownership — who's responsible for each action
Target timescales for completion
A note on what triggers the next review
Making sense of your FRA
If your last Fire Risk Assessment came back with a rating you're not sure how to act on — or you're inheriting a building with an FRA you didn't commission — it's worth having a professional walk you through what it actually means for your specific building.
