Fire Assessment Frequency: When to Review

A fire risk assessment is not a certificate to file away until a renewal reminder arrives. It is a live record of how people can be protected in the building as it is actually occupied, altered and managed. Getting fire assessment frequency right means reviewing risk before a change creates an avoidable gap in compliance, safety or insurance evidence.

For the responsible person, the practical question is rarely simply, “How often is a fire risk assessment legally required?” The better question is whether the current assessment still reflects the premises, the people in it and the fire precautions that are in place.

What does the law say about fire assessment frequency?

Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must make a suitable and sufficient fire risk assessment and keep it under review. The Order does not set one fixed renewal interval for every type of premises. Instead, it requires the assessment to be reviewed regularly and where there is reason to suspect it is no longer valid, or there has been a significant change in the matters to which it relates.

That wording matters. A small, well-managed office and a high-occupancy block with sleeping residents do not carry the same risk profile. A fixed annual cycle can be sensible for either building, but it is not a substitute for reviewing the assessment when circumstances change.

Where five or more people are employed, or a licence or alteration notice applies, the significant findings of the assessment must be recorded. In practice, clear written documentation is valuable for all responsible persons. It demonstrates the basis for decisions, gives staff and contractors a usable action plan, and provides evidence for insurers, lenders, conveyancers and enforcing authorities.

A practical review cycle for UK premises

For many commercial, public-sector and residential buildings, arranging a formal review every 12 months is a prudent starting point. It keeps actions visible, checks whether recommendations have been completed, and avoids the common problem of an assessment becoming quietly outdated.

Some lower-risk premises may justify a longer interval between full reassessments, provided the responsible person carries out ongoing checks and the building, occupancy and management arrangements remain stable. Conversely, higher-risk or more complex premises may need more frequent professional attention. Examples include care environments, buildings with vulnerable occupants, HMOs, large residential blocks, schools, mixed-use premises and properties undergoing change.

A useful approach is to separate three activities. Routine fire-safety checks should happen throughout the year. A management review should confirm that the assessment remains valid. A full reassessment should be commissioned when the risk profile, building fabric or control measures have materially changed. The right fire assessment frequency therefore depends on risk, not just a date in the diary.

Routine checks are not the same as a new assessment

Weekly alarm tests, monthly emergency-lighting checks, fire-door inspections and evacuation-drill reviews are essential parts of fire-safety management. They do not automatically amount to a new fire risk assessment.

However, these records often reveal the reasons a reassessment is needed. Repeated faults, blocked escape routes, damaged doors, missing signs or a failed evacuation drill indicate that the control measures assumed in the assessment may no longer be effective. A good review connects those day-to-day findings to the wider risk assessment rather than treating each issue in isolation.

Changes that should trigger an earlier review

Do not wait for an annual anniversary if the premises have changed. The following events commonly justify an immediate review and, in some cases, a fresh assessment by a competent assessor:

• Building works, refurbishment, extension, conversion or changes to compartmentation, layouts, escape routes or the external wall system.
• A change in use, such as offices becoming short-term accommodation, a shop gaining a storage area, or a building introducing overnight stays.
• New tenants, a material increase in occupancy, lone working, altered shift patterns or the arrival of people who may need assistance to evacuate.
• Installation, removal or substantial alteration of fire alarms, emergency lighting, fire doors, smoke-control systems or other fire precautions.
• A fire, near miss, false-alarm trend, enforcement contact, insurer requirement or a finding that a previous action has not been completed.

Not every change requires a complete report from scratch. Replacing like-for-like furniture in a small office may only need a documented management note. Removing a protected corridor, converting a flat into an HMO, or changing a warehouse process can alter the assessment fundamentally. The key is making a proportionate, recorded judgement rather than assuming the last report covers everything.

Why annual reviews are often the sensible baseline

An annual review works well because buildings rarely stand still for a full year. Staff change, storage accumulates, contractors make minor alterations, maintenance records develop gaps and recommendations can lose ownership. A yearly review creates a defined point at which these details are checked together.

It can also support insurance and property transactions. Insurers and professional advisers generally want evidence that the responsible person is managing fire risk actively, not merely holding an old document. A current, detailed assessment with an action plan, review date and supporting records is more persuasive than a report that was technically acceptable when issued but no longer describes the premises.

For landlords and managing agents, annual review dates can be coordinated with planned maintenance and access arrangements. This reduces disruption for occupiers and makes it easier to verify that remedial works, including any fire alarm installation requirements, have been completed properly.

Who should decide whether the assessment is still suitable?

The legal duty remains with the responsible person, even when a specialist is appointed to undertake the assessment. This may be the employer, building owner, landlord, managing agent or any person with control over part of the premises.

A competent assessor brings an independent, methodical view of hazards, people at risk, means of escape, fire protection and management arrangements. They should also explain the significance of findings in practical terms. A report that lists defects without identifying priorities, responsibility and appropriate timescales creates work but does not necessarily improve safety.

PAS 79 provides a recognised framework for structured fire risk assessment reporting. For organisations managing several premises, consistency in the assessment method and digital record keeping helps compare risks, track actions and demonstrate a clear compliance process across the portfolio.

Keep evidence between formal reviews

The assessment is only one part of the compliance picture. Keep the report alongside records of alarm and emergency-lighting testing, fire-door checks, staff training, drills, maintenance certificates, remedial works and any decisions made following a change. Cloud-based access can be particularly useful where managers, directors, agents and contractors need to work from the same current records.

When an action cannot be completed immediately, record why, the interim precautions being used and the target completion date. This is not an excuse to leave a serious risk unresolved. It is a transparent way to show that the issue is being controlled while a practical solution is arranged.

Avoid the two common mistakes

The first mistake is treating an annual review as a legal safe harbour. If a significant change occurs in month two, waiting until month twelve is difficult to justify. The second is assuming that any informal walk-round counts as a review. A review should be documented, should test whether the existing findings remain accurate, and should result in an updated assessment where necessary.

Equally, avoid commissioning unnecessary reassessments simply because a calendar date has passed. The appropriate level of work should reflect the property and the changes made. A competent adviser can distinguish a straightforward documented review from a full site assessment, helping to control cost without weakening compliance.

For premises across London and the South East, arranging the review around occupied buildings, tenant access and operational hours can be as important as the review itself. Early planning helps, but urgent assessments are sometimes needed for an insurer query, sale, lease or enforcement concern.

If you are unsure whether a recent change affects your fire risk assessment, treat that uncertainty as a reason to ask the question now. A timely, properly documented review protects occupants first and gives the responsible person a clear, defensible record of the decisions made.
