Emergency Lighting in HMOs: What Landlords Are Required to Provide

Councils have refused HMO licence renewals over emergency lighting alone. Not because the lights were broken, but because the landlord had no logbook, no annual certificate, and no evidence of testing. The system was installed, it worked, and it still cost them their licence renewal. That is the level of documentation this obligation requires.

Most HMO landlords either assume emergency lighting only applies to large blocks and commercial buildings, or they installed it years ago and have not thought about it since. Both assumptions are expensive. Here is what the law actually requires, what BS 5266-1:2016 demands, and how to stay clearly on the right side of it.

Who is responsible?

Under the Regulatory Reform (Fire Safety) Order 2005, the "responsible person" for an HMO must take all reasonable steps to ensure adequate means of escape are available and can be safely used in an emergency. Emergency lighting is part of that. It is not optional for properties that meet the threshold: it is a legal duty, and failure to comply can result in unlimited fines, prohibition notices, or in serious cases, imprisonment.

Does your HMO need emergency lighting?

There is no single blanket rule, but the thresholds are lower than most landlords think.

• 2-storey HMO: Conventional mains lighting may be sufficient if escape routes have natural light and the layout is simple. Not automatically required, but your council's HMO licence conditions may specify otherwise.
• 3 or 4-storey HMO: Required where escape routes lack natural light or the layout is complex. Most inner-city or converted 3-storey HMOs will need it.
• 5 or more storeys, or 5 or more occupants: Emergency escape lighting in communal areas is essentially mandatory. Corridors, stairwells, shared kitchens, and all routes to final exits must be covered.

Even if your property sits at the lower end, council licence conditions can impose stricter requirements than the national baseline. Always check the specific conditions attached to your licence, not just general guidance.

What "compliant" emergency lighting actually means

The relevant standard is BS 5266-1:2016, the code of practice for the design, installation, and maintenance of emergency lighting systems. When your fire risk assessor or council inspector refers to compliant emergency lighting, this is what they mean.

The key requirements in practice:

• Duration: Systems in premises where people sleep must provide a minimum of three hours of illumination when mains power fails. A system that only lasts one hour does not comply.
• Coverage: Illumination is required along the full escape route, at every change of direction, at every staircase, at each final exit, and near any fire safety equipment such as extinguishers and alarm call points.
• Fittings: Ordinary mains light fittings do not count. You need BS 5266-compliant self-contained luminaires with integrated batteries, or a central battery system. Self-contained units are the most common solution in converted HMOs.
• Fire door visibility: Emergency lighting must be positioned so that fire door signage and the door itself are clearly visible when the system activates.

The testing cycle you must follow

Installing compliant fittings is the start of the obligation, not the end. BS 5266-1:2016 specifies a testing regime that must be followed and documented.

Monthly functional test

Once a month, briefly interrupt the mains supply to each luminaire. This is called a flick test. The purpose is to confirm the battery activates and the light comes on. It takes seconds per fitting. Record the date, which fittings were tested, and whether any failed. Faults must be repaired promptly, and the date of repair goes in the logbook.

Annual full-duration test

Once a year, mains power is cut to the system and every luminaire must remain lit continuously for three hours. This is not a job you can do yourself. It requires a qualified electrician or fire safety professional who will issue a formal certificate on completion. Some councils, including Oxford, require landlords to submit that certificate as part of their HMO licence compliance. Do not wait to be asked.

The logbook: why it matters as much as the system itself

Enforcement officers do not just look at whether the lights work. They ask for the logbook. If you cannot produce a record of monthly tests and an annual certificate, you are non-compliant even if the system is functioning correctly.

Your logbook needs to record:

• Date of each monthly functional test
• Which luminaires were tested
• Any faults found and the date they were remedied
• Date of each annual full-duration test
• Name of the engineer who carried out the annual test
• Copy of or reference to the annual certificate

A simple spreadsheet or physical logbook works. There is no prescribed format, but it must exist and be up to date.

Common mistakes that catch landlords out

• Installing once and assuming it stays compliant. Building changes, extra rooms, altered escape routes, or a wall repositioned during renovation can mean your existing coverage no longer meets the standard. Review after any physical change to the property.
• Confusing emergency lighting with fire alarm testing. They are separate obligations with separate testing cycles. The monthly flick test for emergency lighting is not the same as testing your fire alarm panel.
• Using standard mains fittings. LED downlights and ordinary bulkhead fittings do not constitute emergency lighting. Fittings must have an internal battery and be rated to BS 5266.
• No logbook. The single most common enforcement issue. A system that works perfectly but has no documented test history gives councils grounds to require immediate remedial works at licence renewal.

How this feeds into your fire risk assessment

Your HMO fire risk assessment must identify whether emergency lighting is required for your property and whether current provision is adequate. If it does not address emergency lighting explicitly, the assessment is incomplete. Under BS 9792:2025, a properly structured assessment will flag storey count, occupancy level, and escape route complexity: all the factors that determine whether your emergency lighting provision is correct.

If your assessment is out of date or never covered this area, revisit it before your next licence renewal or council inspection. FRASafe guides you through a BS 9792:2025-aligned assessment: free to complete, £45 for the council-ready PDF.

Summary

Emergency lighting is a tested, documented, ongoing obligation. Here is what you need to have in place:

1. BS 5266-1:2016-compliant luminaires covering all escape routes, changes of direction, stairwells, and final exits
2. A monthly functional test with results logged each time
3. An annual full-duration 3-hour test carried out by a qualified professional, producing a certificate
4. A logbook that records all of the above

If your property is 3 or more storeys, has 5 or more occupants, or your licence conditions specify it, you need this system in place now. If you have not tested or logged anything for more than a year, sort that before your next inspection, not after.
