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.
