Do Landlords Need a Fire Risk Assessment? A UK Guide for Responsible Persons

It depends on what you let. If you rent out a building with any communal area — a block of flats, a shared house, a house in multiple occupation, or a flat above a shop — then yes, the law requires a fire risk assessment of the parts you control, and you are the person legally on the hook for it. If you let a single self-contained house or flat to one household, you do not need a formal fire risk assessment of that dwelling, but you do have detector and maintenance duties that catch every landlord.

This guide sets out where the line sits, what "responsible person" actually means for a landlord, and the decision most landlords get stuck on: can I do this myself, or do I need to pay an assessor?

This article summarises UK fire safety and housing law for educational purposes and is not legal advice. The responsible person — usually the landlord — carries the legal liability for fire safety, even where the assessment is carried out by someone else. For specific compliance questions, consult a competent fire risk assessor or your local fire and rescue authority.

When a Landlord Legally Needs a Fire Risk Assessment

The governing law in England and Wales is the Regulatory Reform (Fire Safety) Order 2005 — usually called the Fire Safety Order. It places duties on the "responsible person" for non-domestic premises and for the common parts of residential buildings.

The key distinction for landlords is the common parts:

• Single dwelling, one household, no shared areas (a standalone house or a self-contained flat let to one family): the Fire Safety Order does not require a formal fire risk assessment of the inside of that dwelling. Your duties come from housing law and the alarm regulations below.
• Any building with communal areas (blocks of flats with a shared hallway or stairwell, shared houses, HMOs, purpose-built blocks): the Fire Safety Order applies to those common parts, and you must carry out and act on a fire risk assessment of them.
• Mixed-use buildings (residential above a commercial unit): the commercial premises are squarely within the Order, and the residential common parts are too.

If you are not sure whether a particular property has "common parts" in the legal sense, the practical test is whether two or more households share any route, space, or facility — an entrance hall, a stairwell, a bin store, a shared kitchen. If they do, you have common parts and the Order applies.

Houses in multiple occupation carry the most demanding requirements because they layer housing-licence duties on top of the Fire Safety Order. We cover those separately in our HMO fire risk assessment guide.

The Duties That Catch Every Landlord — Even Single Dwellings

Even where the Fire Safety Order does not require a formal assessment, landlords in England have detector duties under the Smoke and Carbon Monoxide Alarm (England) Regulations 2015, as amended from 1 October 2022. The gov.uk landlord guidance states a landlord must:

• "Ensure at least one smoke alarm is equipped on each storey ... where there is a room used as living accommodation"
• "Ensure a carbon monoxide alarm is equipped in any room used as living accommodation which contains a fixed combustion appliance (excluding gas cookers)"
• "Ensure smoke alarms and carbon monoxide alarms are repaired or replaced once informed and found that they are faulty"

A local housing authority can serve a remedial notice for non-compliance and, ultimately, impose a civil penalty of up to £5,000. These are baseline duties — they apply whether or not a fire risk assessment is also required.

What "Responsible Person" Means for a Landlord

Article 3 of the Fire Safety Order defines the responsible person. For premises that are not a workplace, it means:

"(i) the person who has control of the premises (as occupier or otherwise) in connection with the carrying on by him of a trade, business or other undertaking (for profit or not); or (ii) the owner, where the person in control of the premises does not have control in connection with the carrying on by that person of a trade, business or other undertaking."

In plain terms: if you let property as a business, you have control of the common parts and you are the responsible person. Where a managing agent runs the building day-to-day, responsibility can be shared — but it does not evaporate. The duty to carry out the assessment can be delegated to a competent person; the legal responsibility cannot.

This is the single most important point for landlords to internalise: you can pay someone to do the assessment, but if it turns out to be inadequate, the liability is yours. That changes how you should think about the own-vs-hire decision below.

Can You Do It Yourself, or Should You Hire an Assessor?

The Fire Safety Order does not prescribe a qualification. Article 9(1) requires that "the responsible person must make a suitable and sufficient assessment of the risks to which relevant persons are exposed," and the Order requires you to appoint a competent person where you lack the competence yourself.

Here is an honest way to make the call.

You can reasonably do your own assessment when:

• The building is small and low-risk — say, a two-flat conversion with a short, simple shared hallway and a single straightforward escape route.
• You understand fire spread, escape routes, detection, and fire doors well enough to spot a deficiency.
• There is no sleeping risk beyond ordinary domestic occupancy and no building-height complexity.

You should engage a competent assessor when:

• The building has sleeping risk and multiple households (HMOs, larger blocks).
• The building is tall enough to bring in the Fire Safety (England) Regulations 2022 — the over-11-metre fire-door inspection duties, and the high-rise duties at 18 metres or seven storeys.
• You are not confident you could defend your findings to an enforcing officer.

A competent assessor brings method, indemnity insurance, and an outside eye — and crucially, a documented basis you can stand behind if a fire and rescue authority audits the building. For a sense of what that costs, our fire risk assessment cost guide breaks down fees by building type, and the FRA cost calculator gives a quick estimate for your specific property. The competence requirements to look for when you hire are set out in our fire risk assessment guidelines — though note that for the recurring obligation, the real cost is not the first assessment but keeping every property's review date current.

What a Suitable and Sufficient Assessment Covers

Whether you carry it out yourself or commission it, a competent fire risk assessment for a let building works through the same ground:

• Fire hazards — ignition sources and combustible materials in the common parts (electrical intake cupboards, bin stores, stored items in hallways).
• People at risk — residents, visitors, anyone with reduced mobility, and how they would become aware of and escape a fire.
• Means of escape — protected routes, travel distances, final exits, and whether escape routes are kept clear.
• Detection and warning — the right system for the building, tested and maintained.
• Fire doors and compartmentation — flat entrance doors onto common parts (in scope since the Fire Safety Act 2021), self-closers, and fire stopping between units.
• Management — who maintains what, how residents are informed, and the record of the assessment itself.

Since 1 October 2023, under Section 156 of the Building Safety Act 2022, the responsible person must record the assessment in full in all circumstances — the old "only if you have five or more employees" threshold is gone. Whatever the size of the building, the written record is now mandatory.

A Practical Checklist for Landlords

1. Identify whether the property has common parts. If yes, the Fire Safety Order applies and an assessment is required.
2. Confirm you have working smoke and CO alarms to the standard above, regardless of whether an assessment is required.
3. Decide honestly whether the building is within your competence to assess, or whether to engage a competent assessor.
4. Make sure the assessment is recorded in full and kept where you can produce it.
5. Set a review date and the events that would trigger an earlier review — and put it somewhere you will not lose it. Our review date calculator helps you work out a sensible schedule.
6. Act on the findings. An assessment that identifies deficiencies but is never acted on is worse than useless in an enforcement context.

Summary

Landlords need a fire risk assessment whenever they let a building with communal areas, a shared house, an HMO, or mixed-use premises — and they are the responsible person legally accountable for it. A single self-contained dwelling let to one household does not need a formal assessment, but every landlord has smoke and CO alarm duties. The own-vs-hire decision turns on building complexity and your own competence — but because the liability stays with you, err toward a competent assessor for anything with sleeping risk or height complexity.

If you manage several properties, the ongoing job is not the first assessment — it is keeping every property's review current and acting on findings. AssessKit is built for the assessors and firms who do this work repeatedly, with a client and site portfolio, action tracking, and review reminders so nothing falls through. Start free — the Free plan includes two assessments a month, with no card required. See full pricing or read about who is building it.
