Fire Risk Assessment Reviews: When an Update Is Enough vs a New One

A landlord can hold a tidy, professional looking fire risk assessment and still be served a prohibition notice. It usually happens the same way: a loft became an extra bedroom, the alarm was never upgraded to match, and the document in the file still describes the property as it stood two years ago. To a fire officer, an assessment that no longer matches the building is worth about as much as no assessment at all, and the enforcement powers run the same, from an enforcement notice to prosecution and a potentially unlimited fine.

This is why the fire risk assessment review matters as much as the original assessment. The Regulatory Reform (Fire Safety) Order 2005 (the RRO 2005) never asked you to produce a document once and file it forever. It asks you to keep the assessment current, which raises the question every landlord and business owner eventually hits: how often should you review your FRA, and when is a quick review enough versus a full fresh assessment? Get that judgement right and you save money on needless reassessments while staying on the right side of the law.

The law wants a living assessment, not a filed document

Under the RRO 2005, the responsible person (usually the landlord, freeholder, or business owner) must carry out a suitable and sufficient fire risk assessment and then keep it under review. Article 9 is explicit: the assessment must be reviewed regularly so it stays up to date, and reviewed again whenever there is reason to suspect it is no longer valid or there has been a significant change to the premises or the way they are used. If you want the full detail, we cover what the RRO 2005 demands of HMO landlords separately.

The same duty runs across the UK, though the wording sits in different places. England and Wales work under the RRO 2005. Scotland uses the Fire (Scotland) Act 2005 and its regulations, and Northern Ireland the Fire and Rescue Services (Northern Ireland) Order 2006. All three demand the same thing in practice: the assessment reflects the building as it is today, not as it was when you first paid for it.

Notice what the law does not do. It never names a fixed expiry date or a legal review interval. That silence is deliberate. A quiet, unchanged single let needs far less frequent attention than a busy 8 bed HMO with a rotating student population. The duty is proportionate, which puts the judgement, and the responsibility, on you.

Review versus new assessment: the real difference

People use the two words as if they mean the same thing. They do not, and the gap between them is where landlords either save money or get caught out.

A review

A review is a check that your existing assessment is still valid. You walk the property with the current document in hand and confirm that what it describes is still true: the escape routes are clear, the fire doors still close, the alarm still covers the layout, and the significant findings you flagged last time have been actioned. If small things have shifted, you update the assessment in place and note what changed. A review assumes the core assessment is sound and simply keeps it honest.

A fresh assessment

A fresh assessment starts again from the building itself. You reassess the hazards, the people at risk, the escape strategy, and the fire precautions as though you were meeting the property for the first time. You do this when the premises have changed enough that patching the old document would be papering over the cracks, or when the old assessment was never any good to begin with.

Here is the practical test. If you can honestly read your last assessment and say "yes, this still describes my building and my risks," a review is enough. If you find yourself crossing out whole sections, you need a new one.

When a review is enough

Most years, for most properties, a review is all you need. The building has not structurally changed, the same kind of occupants come and go, and your fire precautions are holding up. A review is the right tool when:

• Nothing structural has changed and the layout matches your last assessment.
• You are confirming that previous action points (a self closing device, an emergency light, a missing alarm head) have actually been fixed.
• Tenants have turned over but the type of occupancy is unchanged, for example one set of sharers replacing another.
• You are carrying out your routine annual check to keep the record current.
• Small items have drifted, such as a fire action notice that has fallen down or an extinguisher past its service date, which you fix and note.

A review is quick, cheap, and often something a competent landlord can do without paying an assessor every time, especially for a smaller HMO. Doing it on schedule is what stops a minor drift from hardening into a major failing.

When you need a brand new assessment

Certain events break the old assessment outright. When one of these happens, do not wait for your annual date, and do not try to stretch a review over it. Commission a fresh assessment promptly.

Material building works or layout changes

A loft conversion, a new partition, a removed wall, an extension, converting a house into an HMO, or changing the number of storeys or bedrooms all alter the escape routes and compartmentation your assessment was built on. Any material change to the fabric or layout means the old document no longer describes the building.

A change of use or occupancy

Moving from a family let to an HMO, taking in more tenants, housing more vulnerable occupants (elderly residents, people with limited mobility, children), or switching to short term letting all change who is at risk and how they would escape. A change in the people is as significant as a change in the walls.

A fire or a near miss

Any fire, however small, and any near miss such as a chip pan flare up or an alarm that failed to sound, tells you something in your fire precautions did not work as planned. That is a direct prompt to reassess rather than review.

New regulation or standards

When the legal or standards landscape shifts, older assessments fall behind. The Fire Safety (England) Regulations 2022 added specific duties for responsible persons, and BS 9792:2025 reshaped how HMO assessments are structured and graded. A significant change in the rules is a legitimate reason to commission a fresh, current assessment rather than lean on an older method.

How often should you review your fire risk assessment?

Because the law sets no fixed interval, best practice fills the gap, and the settled answer for rented and shared housing is clear. Review at least once a year, and reassess from scratch periodically or whenever a trigger occurs.

For a straightforward HMO with no changes, an annual review plus a full fresh assessment every few years (many assessors suggest roughly every three to five years) is a sensible, defensible programme. Higher risk premises, larger HMOs, buildings with vulnerable occupants, or properties with a history of fire safety concerns should be reviewed more often, every six to twelve months. If you want the cadence broken down by property type, read our guide on how often an HMO needs a fire risk assessment.

Whatever schedule you set, put the next review date in your diary the day you finish. The most common way landlords fall foul of the review duty is not refusing to do it, but forgetting it exists until an inspection or an incident forces the issue.

Documenting the review

A review you cannot prove is a review that, to an inspector, never happened. Every time you review or reassess, record it. You do not need a heavy report for a simple check, but you do need a clear trail.

At a minimum, note the date of the review, who carried it out, what you looked at, what had changed, and what you did about it. Sign it and keep it with the assessment. If nothing had changed, record that too, because "reviewed on this date, no material change, no action required" is exactly the evidence a fire officer wants to see.

This record sits alongside your alarm tests, fire door checks, and emergency lighting logs as part of the paper trail that shows you have managed fire safety continuously rather than in one forgotten burst. Our guide to the fire safety records an HMO landlord must keep sets out the full list.

Next steps

Pull out your current fire risk assessment and read it against the building as it stands today. If it still describes your property honestly, book in a dated review and note the next one. If you are crossing out sections, or a conversion, change of use, fire, or new regulation has landed since you wrote it, start a fresh assessment now rather than waiting for a renewal date that the law never set.
