UK Fire Safety for Hotels & HMOs — BS 5839, BS 5266 — 2026 Guide

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.
