HMOs & Converted Premises

Sleeping risks in houses in multiple occupation and converted residential premises are among the most serious — and among the most frequently under-assessed — in the private rented sector.

The sector where sleeping risk and inadequate assessment most frequently meet.

HMOs and converted premises occupy a specific and demanding position in fire safety law. The risk profile — sleeping occupants in shared accommodation, frequently converted Victorian and Edwardian stock with compromised original compartmentation, unpredictable occupancy patterns, high turnover of residents unfamiliar with escape routes, and shared means of escape that serve multiple households — creates a combination of factors that a generic assessment methodology is poorly equipped to address.

Enforcing authorities — fire and rescue services and local housing authorities — give this sector particular attention. The statistics are not reassuring: fire fatalities in the private rented sector are disproportionately concentrated in HMOs and bedsit-type accommodation. An adequate fire risk assessment is not a bureaucratic requirement in this environment; it is the mechanism by which the occupants' ability to escape is evaluated and protected.

The Responsible Person — typically the landlord or managing agent — carries full legal accountability. An inadequate assessment, or an assessment that is not reviewed when the premises or occupancy changes, creates personal criminal liability. It also creates significant exposure under the Housing Act 2004 HHSRS framework, which operates in parallel and is enforced by the local housing authority independently of the fire and rescue service.

Regulatory Reform (Fire Safety) Order 2005 (as amended)
The primary fire safety legislation. Applies to the common parts of HMOs and converted premises where there are two or more domestic premises. Requires a suitable and sufficient fire risk assessment of those common parts.

Housing Act 2004 — HHSRS
The Housing Health and Safety Rating System assesses fire as a Category 1 hazard in residential premises. Enforced by the local housing authority independently of the FRS. Both enforcement routes can run simultaneously — and often do.

LACORS Housing Fire Safety Guidance
The primary practical guidance document for fire safety in existing residential premises, including HMOs and converted flats. Sets out the risk-based approach to common escape routes, fire detection standards, door standards and compartmentation expectations for different property types.

HMO licensing conditions
Mandatory HMO licensing (5 or more occupants, 2 or more households) and any additional licensing schemes imposed by the local housing authority typically require a current fire risk assessment as a licence condition. Failure to maintain a current assessment can affect licence renewal. See do I need a fire risk assessment for my HMO? for the full picture.

BS 9991:2015 & BS 8674:2025
BS 9991 covers fire safety in the design, management and use of residential buildings. BS 8674:2025 sets out the competence framework for fire risk assessors — increasingly referenced by enforcing authorities and procurement specifications.

The FSO and HHSRS can both apply — simultaneously, independently, and with different consequences.

One of the least well understood aspects of HMO fire safety is that two distinct enforcement regimes can apply to the same building at the same time, operated by different authorities, under different legislation, and with different remedies available to each.

The fire and rescue service enforces the Regulatory Reform (Fire Safety) Order 2005 (as amended) in the common parts. An enforcement notice under Article 30 FSO requires specific remedial action within a specified timeframe. A prohibition notice under Article 31 FSO can restrict or prohibit the use of part or all of the premises — immediately, if necessary, on grounds of serious risk to relevant persons.

The local housing authority enforces the HHSRS under the Housing Act 2004 in relation to the condition of the individual dwelling units as well as the common parts. A Category 1 hazard — which fire routinely is in poorly managed HMOs — carries a duty to take enforcement action. That action can include an improvement notice, a prohibition order, or emergency remedial action at the landlord's expense.

A fire risk assessment that addresses only the FSO common parts dimension, without considering the HHSRS fire hazard profile of the individual units, is an incomplete picture of the premises' fire safety position. SimplyNeat assessments are written with an awareness of both frameworks. For a plain-English breakdown of how the two divide up, see FSO vs HHSRS: the two enforcement routes for HMOs explained.

Fire & Rescue Service
FSO Enforcement
Common parts of HMOs with 2+ domestic premises. Enforcement Notice (Article 30) or Prohibition Notice (Article 31). Criminal prosecution on non-compliance. Brian holds former A31 signatory authority — the power to issue these notices.
Local Housing Authority
HHSRS Enforcement
Dwelling units and common parts under Housing Act 2004. Category 1 hazard (fire) triggers enforcement duty. Improvement notice, prohibition order or emergency remedial action. Runs independently of FRS action.

An assessment that reflects the actual risk to actual occupants in this building.

Every assessment is carried out personally by Brian Neat. Not sub-contracted, not delegated. The report you receive is based on direct observation of the specific premises on the day of the assessment — not a standard form completed from photographs sent in advance. Landlords and managing agents with HMOs in Hampshire are covered locally from Petersfield; portfolios elsewhere are assessed nationwide.

The standard HMO assessment is a Type 1 non-destructive inspection covering the common parts only — entrance hall, corridors, stairwells, landings, common rooms and the external envelope. The front doors of individual letting units mark the boundary of the standard assessment. Access beyond those doors is not normally available and is not required to discharge the Responsible Person's duty under the Regulatory Reform (Fire Safety) Order 2005 (as amended) in relation to the common parts.

Where a Type 3 assessment is required — covering access to a sample of individual dwelling units, for example where the condition of compartmentation within units is uncertain and directly relevant to the risk in the common escape route — this can be discussed and scoped separately, subject to access being arranged with occupants.

Findings are proportionate to the actual risk identified. In sleeping risk premises, compartmentation deficiencies, fire door failures and detection inadequacies carry greater weight than they would in a daytime-occupancy commercial building — because the ASET (Available Safe Escape Time) is fundamentally compressed when occupants are asleep and unaware of a developing fire. That relationship between the finding and its consequence for occupants is made explicit in every relevant finding.

The action plan is prioritised and actionable. Items that require immediate attention are clearly distinguished from those that can be addressed on a planned basis. The Responsible Person receives a report they can act on — not one that lists every theoretical deficiency at the same priority level.

Sleeping risk evaluation — specific assessment of overnight occupancy, the implications for fire detection standards and the adequacy of warning arrangements to wake sleeping occupants
Common escape route assessment — corridors, stairwells, final exits and their condition, width, obstructions and adequacy under the LACORS framework for the property type
Fire compartmentation — walls, floors, service penetrations and the condition of fire doors throughout the common parts, assessed against the protection they are required to provide for the escape route
Fire detection and alarm systems — grade, category, coverage and condition, assessed against the sleeping risk profile and LACORS guidance for the specific property type and occupancy
Emergency lighting — coverage, condition and maintenance records for escape route lighting and exit signage
Fire doors — condition, self-closing function, seals, gaps and overall performance for each door on the escape route and into individual letting units, assessed individually
Ignition sources and housekeeping — common area electrical installations, cooking arrangements, laundry, storage in escape routes, and arson risk from accessible ground floor areas
Management arrangements — fire safety information provided to occupants, testing and maintenance records, and whether the Responsible Person's systems for managing fire safety are adequate
Full written report — with overall risk rating, prioritised action plan and photographic evidence, written for the Responsible Person and suitable for production to the fire and rescue service or local housing authority

A deficiency that is tolerable in a daytime office may not be tolerable in an HMO. The assessment must make that distinction.

The fundamental question in any fire risk assessment is whether occupants have sufficient time to escape from a developing fire — whether the Available Safe Escape Time (ASET) exceeds the Required Safe Escape Time (RSET). In premises where occupants are awake, familiar with the building and able to self-evacuate, many deficiencies that reduce ASET are tolerable because the margin remains adequate.

In sleeping risk premises, that margin is fundamentally different. An occupant who is asleep will not detect a developing fire themselves. Detection — and warning — depends entirely on the fire alarm system. The time between ignition and a sleeping occupant being awoken, orientated, dressed and moving toward the exit is substantially longer than for an alert, aware occupant. A gap in compartmentation, a door that fails to self-close, or a detector in the wrong category all have greater consequences in this environment because the ASET is already under greater pressure.

An assessment of an HMO that does not make this distinction explicitly — that records a deficiency at the same priority as it would in a non-sleeping-risk premises — is not giving the Responsible Person an accurate picture of the risk their occupants face. SimplyNeat assessments make the sleeping risk triage explicit: where a finding carries greater weight because of the sleeping risk profile, that reasoning is stated, not assumed.

The perspective of someone who has been on both sides of the enforcement desk.

Brian Neat created and led Hampshire FRS's dedicated fire safety enforcement and prosecution team — one of the earliest in the country under the Regulatory Reform (Fire Safety) Order 2005 (as amended). As a Group Manager and A31 signatory, he held the authority to issue enforcement and prohibition notices. He has assessed the same categories of premises from the enforcer's perspective, and understands the framework within which enforcement decisions are made.

That background is directly relevant to HMO clients. Landlords and managing agents who receive an enforcement notice from either the fire and rescue service or the local housing authority need an assessor who understands how that notice was generated, what a proportionate and compliant response looks like, and how to demonstrate to the enforcing authority that the risk has been addressed — not merely that action has been taken.

It is equally relevant to landlords who have not yet received a notice. An assessment produced with an understanding of the enforcement framework is an assessment that will withstand scrutiny if that scrutiny ever arrives. The value of getting it right is not abstract — it is the difference between a straightforward compliance position and a prosecution.

On acquisition of the property — before the first letting if possible
At HMO licence application or renewal — a current FRA is typically a licence condition
Following any structural alterations, room conversions or changes to the layout of the escape route
Change in the number of occupants or household composition — particularly any increase in the number of persons sharing
Following any fire, near-miss, or contact from either the FRS or local housing authority
Where the existing assessment is more than two years old, or was produced by a previous assessor of uncertain competence
At least annually for higher risk HMOs — larger properties, older converted stock, higher occupancy

HMO fire risk assessments — frequently asked.

Do I need a fire risk assessment for my HMO?

Yes. The Regulatory Reform (Fire Safety) Order 2005 applies to the common parts of any HMO or converted premises containing two or more sets of domestic premises, and requires a suitable and sufficient fire risk assessment of those areas. As the landlord or managing agent you are usually the Responsible Person and carry the legal duty personally.

Is a fire risk assessment required to get or renew an HMO licence?

In practice, yes. Mandatory HMO licensing applies to properties with five or more occupants forming two or more households, and many councils run additional or selective licensing schemes on top. A current fire risk assessment is typically a licence condition, and an out-of-date or missing assessment can hold up a licence application or renewal. For more on the legal basis and what an assessment covers, see do I need a fire risk assessment for my HMO?

What do ASET and RSET mean, and why do they matter more in an HMO?

ASET is the Available Safe Escape Time — how long conditions stay survivable after a fire starts. RSET is the Required Safe Escape Time — how long occupants actually need to get out. Safety depends on ASET exceeding RSET. In an HMO occupants are often asleep and unfamiliar with the building, so RSET is longer and the margin is tighter — which is why a gap in compartmentation, a fire door that won't self-close or a detector in the wrong category carries more weight here than in a daytime office.

Does the same HMO get assessed under both the Fire Safety Order and HHSRS?

It can. The fire and rescue service enforces the Fire Safety Order in the common parts, while the local housing authority enforces the Housing Health and Safety Rating System (HHSRS) under the Housing Act 2004 across the units and common parts. Fire is one of the hazards HHSRS assesses, and in poorly managed premises it routinely scores as a Category 1 hazard. The two regimes run independently and can act at the same time, so a complete picture needs to keep both in view.
