Part of the Hotel & HMO Refurb Supplier Guide series
Read the full UK Hotel & HMO Refurb Supplier Guide for room-by-room electrical and bathroom BOMs alongside this fire safety spec.
Short answer: for any UK hotel or HMO, you need a BS 5839-1 Category L1 or L2 fire detection system, BS 5266 emergency lighting throughout escape routes, FD30 fire doors with intumescent seals + self-closers on every guest room and corridor door, and extinguishers and signage per the FRA. The Fire Safety Act 2021 and Fire Safety (England) Regulations 2022 have tightened these obligations — fines for non-compliance reach £5,000 per breach plus criminal prosecution. Detail and BOMs below.
Updated May 2026 · Regulatory Reform (Fire Safety) Order 2005 · Fire Safety Act 2021 · Fire Safety (England) Regulations 2022.
The legal framework — what applies
| Regulation | What it covers | Applies to |
|---|---|---|
| Regulatory Reform (Fire Safety) Order 2005 (RRO) | Duty of care — "responsible person" must conduct Fire Risk Assessment (FRA), implement controls. | All non-domestic premises (hotels, HMOs, restaurants, etc.) |
| Fire Safety Act 2021 | Extends RRO to cover building structure, external walls, flat entrance doors. Post-Grenfell tightening. | Multi-occupancy residential buildings (HMOs, blocks) |
| Fire Safety (England) Regulations 2022 | Mandates: external wall info, FRP info, instructions to residents, evacuation plans for high-rise. | Buildings > 11m or with 2+ residential units |
| Housing Act 2004 (HMO licensing) | Mandatory + selective HMO licensing. Council inspections. | HMOs (5+ persons, 2+ households) |
| Building Regulations Approved Doc B | Construction-side fire safety (compartmentation, escape routes, materials). | New build, extensions, material alterations |
BS 5839 fire detection — what you need where
BS 5839 is split into two parts based on building type:
- BS 5839-1 applies to commercial premises (hotels, restaurants, offices, retail). Mandatory for hotels.
- BS 5839-6 applies to domestic / residential premises (HMOs, flats, residential blocks).
BS 5839-1 categories — hotels
The category determines coverage. For hotels, the typical specifications:
- Category L1 — protection of life. Smoke detectors in every room, corridor, escape route, void. The premium spec for 4★ and 5★ hotels.
- Category L2 — detection in escape routes + rooms with high fire risk (kitchens, plant rooms, laundry). The standard 3★ hotel spec.
- Category L3 — detection in escape routes + rooms opening onto them. Minimum spec; rarely sufficient for hotels.
- Category L4 — escape routes only. Generally insufficient for hotels.
- Category L5 — risk-specific. Bespoke localised system.
BS 5839-6 grades — HMOs
For HMOs, the grade determines power source and signaling:
- Grade D1 — mains-wired with battery backup, no central panel. The standard HMO spec for 1- to 2-storey HMOs.
- Grade C — mains-wired interlinked alarms (radio or hardwired). For larger HMOs (3+ storeys).
- Grade A — fully addressable system with central panel. For high-risk HMOs and larger conversions.
Detector types — where each one goes
| Detector | Where | Why |
|---|---|---|
| Optical smoke | Bedrooms, lounges, corridors, escape routes | Best general-purpose; responds well to smouldering fires |
| Heat detector | Kitchens, kitchenettes, bathrooms (steam = false alarm risk) | Activates on rate-of-rise OR fixed-temperature; immune to cooking smoke and steam |
| CO detector | Any room with gas appliance / solid-fuel / open fireplace | Mandatory in HMOs and rental properties under Smoke and CO Alarm Regs 2015 |
| Multi-sensor | Reception, public lounges, mixed-use spaces | Combines smoke + heat for false-alarm resistance in mixed environments |
BS 5266 emergency lighting — escape route coverage
BS 5266-1 mandates emergency lighting on all escape routes. Coverage requirements:
- Escape route lighting — minimum 1 lux on the centre line of the escape route, ≤ 2m fitting spacing. LED bulkheads (maintained or non-maintained), 3-hour duration.
- Open-area (anti-panic) lighting — minimum 0.5 lux at floor level for any open area > 60m².
- High-risk task area lighting — minimum 15 lux for tasks that, if abruptly stopped, could endanger occupants.
- Exit signage — photoluminescent OR LED-illuminated 'Running Man' EU-standard sign at every exit, change of direction, > 30m intervals.
- Self-test variants — reduce inspection burden. Annual functional test still required.

Fire doors — the FD30 / FD60 spec
UK fire-door ratings indicate minutes of fire resistance:
- FD30 — 30 minutes. The standard for hotel guest bedroom doors and HMO bedroom doors.
- FD60 — 60 minutes. For higher-risk locations — plant rooms, kitchens, areas where fire load justifies extended compartmentation.
- FD90 / FD120 — specialist; high-rise riser cupboards, fuel storage.
Fire door pack — components
An FD30 fire door isn't just the door. Each door needs the full pack:
- Door leaf — BS 476 / BS EN 1634 tested at 30-minute rating
- 3 hinges minimum — BS EN 1935 grade 13 fire-rated hinges
- Self-closer — BS EN 1154 grade 3 minimum (CE marked)
- Intumescent + smoke seal — around the door edge; expands at ∼200°C to seal the gap. Intumescent fire & smoke seals
- Lock / latch — fire-rated lock body and matching keep
- Glazing (if any) — BS 476 / BS EN 1634 tested fire glazing with intumescent glazing seal
- Door retainer (optional) — BS EN 1155 magnetic hold-open, releases on alarm. Fire door retainers
Components must be CE marked and certified to UKCA. Fire doors can fail certification if any single component is non-spec. Astroflame fire-door packs ship as pre-matched kits.
Extinguishers — type and per-floor count
UK fire extinguisher coverage is determined by Fire Risk Assessment, but typical hotel coverage:
| Location | Type | Logic |
|---|---|---|
| Corridors / escape routes | 9L water + 2kg CO₂ per 200m² floor area, max 30m walking distance | Class A + Class C |
| Kitchens | 3L wet chemical + fire blanket | Class F (cooking oils); never use water on oil fire |
| Plant rooms / electrical cupboards | 2kg or 5kg CO₂ | Class C; CO₂ leaves no residue on equipment |
| Reception / public areas | 9L water + 2kg CO₂ | General Class A + Class C coverage |
| Boiler / fuel storage | 6L foam (AFFF) + CO₂ | Class B (flammable liquids) + Class C |

FAQ — common questions
Who is the "responsible person" under the Fire Safety Order?
For hotels: the proprietor / lease-holder. For HMOs: the licence-holder OR the freeholder. They must conduct + document the FRA, implement controls, train staff, and review annually.
How often does the Fire Risk Assessment need to be reviewed?
Annually, OR after any material change — layout change, occupancy change, new fire-related incident, change of use, refurb. Failure to keep the FRA current is itself a breach.
Do I need a BAFE-certified engineer for the fire alarm?
Strictly, no — but you do need a "competent" engineer per BS 5839-1. BAFE certification is the de-facto industry standard.
Can I use battery-only smoke alarms in an HMO?
No. BS 5839-6 Grade F (battery-only) is not permitted for HMOs. Minimum is Grade D1 (mains-wired with battery backup).
What's the difference between BS 5839-1 and BS 5839-6?
BS 5839-1 is for commercial premises (hotels, restaurants); requires a control panel and addressable detection. BS 5839-6 is for residential / domestic premises (HMOs, flats).
Are old-stock 'expired' fire extinguishers legal?
UK extinguishers don't have a statutory expiry date, but: they require annual service by a BAFE engineer; powder discharged every 5 years; CO₂ hydrostatic test every 10 years.
Do I need fire-door retainers (magnetic hold-open)?
Not strictly mandatory, but increasingly expected by FRA assessors for hotel and HMO corridors. See fire door retainers.
What's a "stay put" vs "simultaneous evacuation" strategy?
For most hotels: simultaneous evacuation. For some HMOs and high-rise residential: "stay put" until directed otherwise. The FRA dictates which strategy applies.
Do bedside / guest-room sounders count toward BS 5839-1?
Yes — BS 5839-1 requires the alarm signal to be audible at > 65 dB in every accessible part of the premises (> 75 dB in sleeping areas).
What documentation must I keep on file?
FRA (current + last 5 years). Fire alarm test log. Emergency lighting test log. Extinguisher service history. Fire door inspection log. Staff fire training records. Evacuation drill records.
