Service overview
HMO Fire Alarms, explained without the jargon
What it is
Specialist fire detection and alarm systems for Houses in Multiple Occupation, designed to BS 5839-6 with the grade and category dictated by the property's licensing conditions and fire risk assessment.
Who it's for
Private HMO landlords, student accommodation operators, supported housing providers, and letting agents managing licensed HMO portfolios across South Wales.
When it's needed
Before a new HMO licence application, ahead of a renewal, when adding bedrooms, after a change of use, or following an enforcement notice from the local authority.
Why professional matters
HMOs combine sleeping occupants, shared escape routes and unfamiliar layouts, the highest-risk residential category. The wrong system kills people and ends portfolios.
The cost of ignoring it
Why most failed HMO inspections fail
Risks if left unchecked
●Sounders below the 75 dB at bed-head required to wake sleeping occupants.
●Domestic interlinked detectors used where Grade A is required, with no panel and no monitored cabling.
●Detection missing from kitchens, lounges or principal habitable rooms required under LD2.
●No commissioning certificate, the system 'works' but no inspector can prove when or by whom.
Common mistakes
●Buying a system to suit a budget rather than the licence.
●Assuming the previous landlord's system is still compliant after a refurb.
●Skipping the design stage and asking the installer to 'just put a few heads in'.
●Letting a general electrician fit the system without BS 5839 competence.
Licensing officers do not negotiate. A non-compliant HMO can be served prohibition, the rent stops, and Rent Repayment Orders can apply for up to 12 months of rental income.

Technical detail
Everything that goes into a proper hmo fire alarms
HMO fire alarm requirements vary by local authority, by article 4 direction, and by individual licence conditions. The notes below reflect the schemes we work with across South Wales most often.
Cardiff additional and mandatory HMO licensing
Cardiff Council requires Grade A LD2 minimum for licensed HMOs, with category L2 for higher-risk layouts. Sounders at bed-head must achieve 75 dB. We design directly to the council's published HMO fire safety guidance.
Newport, Swansea, Bridgend and the Valleys
Schemes vary, some require LD1 in three-storey or larger HMOs. We confirm at survey and never under-specify to win a job. The design pack states exactly which clause of the scheme each device satisfies.
Sleeping risk and inter-flat compartmentation
Bedroom-by-bedroom detection, sounders sized for closed-door conditions, and where flats are involved, an interface that activates only the affected flat's sounder to avoid mass evacuation false-alarm fatigue.
Student HMOs and high-turnover lets
We supply tenant-facing 'what to do in a fire' posters keyed to your zone plan and label panels in plain English. False-alarm management plans are part of the handover.
Supported and exempt accommodation
For supported housing with mobility or learning-disability tenants we specify vibrating pads, strobes and PIR-linked cause-and-effect, and document it for the Care Inspectorate.
Article 4 areas and listed buildings
Where chasing cable is restricted we specify EN 54-25 wireless systems with documented battery replacement intervals so the listing officer and the licensing officer both sign off.
