How Often Should Fire Risk Assessments Be Reviewed?

A fire risk assessment can be thorough on the day it is completed and still become unsuitable within months. A new tenant, altered escape route, refurbishment project or change in building use can all change the risks on site. That is why the question, “how often should fire risk assessments be reviewed”, cannot be answered by a single calendar date alone.
For most UK dutyholders, a documented annual review is a sensible and widely accepted compliance discipline. However, the responsible person must also review the assessment whenever there is reason to believe it is no longer valid, or there has been a significant change to the matters to which it relates. Waiting for the annual review after a material change can leave occupants, the organisation and its insurance position exposed.
What the law requires
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must make a suitable and sufficient assessment of fire risks and keep it under review. The Order does not impose one universal interval, such as every 12 months or every three years, for every premises.
Instead, the legal test is whether the existing assessment remains suitable. If it does not, it must be reviewed and revised where necessary. This approach recognises that a small, low-risk office with stable occupancy presents a very different management challenge from a care setting, a large HMO, a school, a place of worship or a mixed-use residential building.
For premises outside England and Wales, the applicable fire-safety legislation differs. The same practical principle remains relevant: assessments and fire precautions need to reflect the building as it is now, not as it was when the report was first issued.
How often should fire risk assessments be reviewed in practice?
A formal review every 12 months is good practice for many commercial, residential and public-facing premises. It creates a clear compliance trail, gives the responsible person an opportunity to check progress against the action plan, and helps identify gradual changes that may otherwise be missed.
A full new assessment is commonly arranged every three to five years where the premises, occupancy and risk profile have remained stable. That range is not a substitute for judgement. Higher-risk buildings, complex premises and properties with vulnerable occupants may require a more detailed reassessment more frequently. Equally, a straightforward annual review may confirm that a previous comprehensive report remains appropriate, with only limited updates required.
The key distinction is between a review and a full reassessment. A review tests whether the existing assessment is still valid and whether recommended actions have been completed. A full reassessment involves a fresh, systematic inspection of the premises, fire hazards, people at risk and existing protective measures. Both should be documented.
Events that require an earlier review
A calendar-based review should never be the only trigger. The responsible person should revisit the fire risk assessment promptly following a change that could affect fire prevention, means of escape, warning arrangements or the people using the building.
Common triggers include:
- alterations, refurbishment, extension works or changes to compartmentation;
- a change of use, such as converting offices to residential accommodation or creating additional sleeping accommodation;
- new processes, equipment, storage arrangements or ignition sources;
- a significant change in occupancy, including more residents, night working, mobility needs or vulnerable persons; and
- a fire, false alarm trend, near miss, enforcement visit, insurer query or repeated failure to complete corrective actions.
Even a change that appears operational rather than structural can matter. For example, storing stock in a corridor may reduce effective escape width. Replacing a manual process with battery charging equipment may introduce a new ignition source. Moving a reception desk can alter how an alarm is raised or how visitors are directed during an evacuation.
When in doubt, it is usually better to obtain competent advice early. The cost and disruption of a timely review are generally far lower than dealing with an incident, enforcement action or a delayed property transaction.
Why annual reviews are valuable even without major changes
Fire safety arrangements can drift. Fire doors are wedged open for convenience, escape routes become temporary storage areas, extinguishers are moved, staff turnover affects fire warden coverage, and maintenance certificates are filed without anyone checking that defects were resolved. These issues do not always require a redesigned fire strategy, but they can undermine the controls recorded in the assessment.
An annual review should therefore consider more than whether the building layout looks unchanged. It should check the status of previous recommendations, review fire alarm and emergency lighting testing records, confirm that fire doors and escape routes are being managed properly, and verify that staff information, evacuation procedures and responsible persons remain current.
For landlords and managing agents, this is particularly useful where several contractors, leaseholders or occupiers have responsibilities. A clear review record helps demonstrate active management rather than reliance on an old report held in a folder or cloud archive.
Matching the review frequency to the premises
Risk profile should drive the level and frequency of scrutiny. A single-occupancy office with a familiar workforce, simple layout and no sleeping risk may be adequately managed through an annual documented review and a periodic fresh assessment. A premises with changing staff, public access, cooking facilities, resident sleeping accommodation or complex evacuation arrangements will usually justify closer attention.
HMOs and blocks of flats require particular care because residents may be asleep, unfamiliar with one another, or less able to respond quickly. Healthcare premises, educational settings and buildings used by people with mobility, sensory or cognitive impairments also require arrangements that reflect the needs of those at risk. In these environments, management changes can be as significant as physical building changes.
There is a practical trade-off. Reviewing too lightly may fail to identify deteriorating controls or new risks. Commissioning a full reassessment every year where nothing has changed may be unnecessary. A competent assessor can help determine whether a documented review, an update to the action plan or a complete reassessment is the proportionate response.
Keep evidence, not just the report
An insurance-compliant fire risk assessment is not a one-off certificate. Insurers, lenders, legal conveyancers and enforcing authorities may want to see the report, but they may also ask what happened after it was issued. The evidence of follow-through is often as important as the findings themselves.
Keep the original report, review records, action plan, photographs where relevant, maintenance documentation and confirmation that remedial works have been completed. Record the date of each review, who carried it out, what was checked, what changed and why the assessment was retained or revised.
Digital document access makes this considerably easier for multi-site operators and property managers. It also prevents a common problem during a sale, refinance or urgent insurer request: having a valid assessment but being unable to locate the latest version or prove that actions were closed.
Who should carry out the review?
The responsible person remains accountable for keeping the assessment current, but they do not need to work alone. A straightforward internal review may be appropriate where the building is stable and the reviewer understands the premises, the existing assessment and fire-safety management requirements.
A competent external assessor is advisable after significant changes, where risks are more complex, when a previous assessment is outdated, or where an independent and detailed report is needed for an insurer, lender, conveyancer or enforcement authority. The assessor should use a recognised methodology, provide clear priorities and explain what practical action is required.
Firelux can arrange comprehensive assessments and review support with detailed digital reporting, helping dutyholders maintain a defensible record while planning remedial work around occupied premises.
Treat the review date as a management deadline
Set the next review date when the current assessment is issued, but do not regard that date as permission to ignore changes until then. Build fire risk assessment review into routine property management, alongside maintenance, contractor controls and tenant communication.
The most useful report is one that continues to guide decisions after the assessor has left. If the building, its people or its fire precautions have changed, act on that information promptly. A current assessment, backed by clear evidence and completed actions, gives occupants safer premises and gives the responsible person confidence when compliance is questioned.
