HMO Fire Safety LACORS Standards: UK Landlord's Complete Guide
The LACORS 2008 guide is the de facto UK standard for HMO fire safety. Property categories, alarm grades, fire doors, escape routes — what councils inspect for HMO licensing.
Quick answer: The LACORS 2008 guide "Housing — Fire Safety" is the de facto UK standard councils apply when inspecting HMOs (Houses in Multiple Occupation) for fire safety compliance. It categorises HMOs into four types (A through D) and sets specific requirements for alarm grades, fire doors, escape routes, and emergency lighting. Without LACORS compliance, you cannot get an HMO licence — and without a licence, you cannot legally let the property as an HMO.
What LACORS is
LACORS = Local Authorities Coordinators of Regulatory Services. In 2008 they published "Housing — Fire Safety", a comprehensive guide for local authority housing officers assessing HMO fire safety. Although LACORS itself was dissolved in 2010, the 2008 guide remains the standard councils apply to HMO licensing decisions across England and Wales.
The 4 LACORS HMO categories
Category A — Small shared house (up to 5 occupants)
- Two-storey or three-storey houses
- Up to 5 occupants sharing facilities
- Used as a single household-type arrangement
- Lower-risk category
Category B — Larger shared house
- 6 or more occupants
- Two-storey or three-storey
- Shared kitchen, bathroom facilities
Category C — Multi-storey HMO
- Three or more storeys
- Multiple letting rooms across floors
- Higher fire risk due to vertical escape route
Category D — Large converted HMO
- Larger HMOs, often student accommodation or bedsit-style
- Multiple shared facilities
- Highest fire-safety standards
LACORS alarm requirements by category
| Category | Alarm grade | What it means |
|---|---|---|
| A | Grade D1 LD2 | Mains-powered with battery backup, interlinked. Smoke detectors in escape routes; heat detectors in kitchen. |
| B | Grade D1 LD2 or LD1 | Same as A but with additional detectors covering more rooms. |
| C | Grade D1 LD1 or Grade A | More comprehensive coverage. Detectors in every habitable room. Grade A = control panel system. |
| D | Grade A LD1 | Full BS 5839-1 system with central control panel, sounder circuits, manual call points. |
Fire door requirements
LACORS typically requires:
- FD30 fire doors on every room opening onto an escape route (30-minute fire resistance)
- Self-closing devices (Perko or overhead closer) on all fire doors
- Intumescent strips and smoke seals in door frames
- Gap dimensions: maximum 3mm at top and sides, maximum 8mm at threshold
- Glass panels (where present) must be fire-rated to match the door rating
Escape route requirements
LACORS sets clear standards for escape routes:
- Minimum width: typically 800-1000mm depending on occupancy
- No locks requiring keys to escape (thumb turns or push-bar only)
- Clear of obstructions at all times
- Smoke control via self-closing fire doors
- Emergency lighting on routes (longer escape distances)
Emergency lighting
For most HMOs over Category A:
- Required on all escape routes that cannot be served by natural light during emergency
- BS 5266-1 standard applies
- Annual 3-hour discharge test
- Monthly visual check
- Maintained for the life of the installation
Records the council expects at HMO inspection
- Current Fire Risk Assessment (specific to the property)
- Weekly alarm test log
- Annual alarm service certificate from a competent person
- Fire door inspection records (at least 6-monthly)
- Emergency lighting test records (monthly and annual)
- Current EICR (every 5 years)
- Gas Safety Certificate (annual)
- PAT testing for landlord-supplied appliances
- Evidence of tenant fire safety briefing
- HMO licence application or current licence
What happens at HMO inspection
- Council housing officer visits (typically by appointment)
- Reviews paperwork (FRA, alarm records, fire door inspections)
- Walks the property — tests alarms, inspects fire doors, checks escape routes
- Reviews tenant evidence of safety briefing
- Reports findings to HMO licensing team
Outcomes:
- Pass: licence issued or renewed
- Pass with conditions: licence issued but with required improvements (e.g., upgrade alarms within 60 days)
- Conditional refusal: licence refused until specific improvements complete
- Refusal: with right of appeal; property cannot be let as HMO during refusal
Common LACORS compliance failures
- Battery-only smoke alarms (not interlinked, not mains)
- Fire doors with self-closers removed or wedged
- Letterbox holes cut into fire doors compromising integrity
- Locked escape routes (key-operated locks)
- Emergency lighting installed but never tested
- FRA template-only, not specific to the property
- Tenant briefing claimed but not evidenced
Council-specific variations
Most UK councils follow LACORS but some apply higher standards:
- London boroughs: often apply additional requirements (especially post-Grenfell)
- Brighton & Hove, Bristol, Manchester, Sheffield: have published their own HMO licensing handbooks
- Scotland: separate Tenement Building law applies; HMO standards similar but with Scottish-specific rules
- Wales: Rent Smart Wales licensing alongside HMO licensing
What this means for landlords
- Before letting an HMO: verify LACORS compliance ahead of council inspection
- Use registered HMO fire safety specialists for FRA and remedial work
- Keep records up-to-date — gaps are the most common reason for licence refusal
- Budget for ongoing compliance: typically £500-£2,000/year per HMO for inspections, services, and minor remedial
