An HMO fire risk assessment checks a shared house against the Fire Safety Order 2005, the LACORS fire safety guidance London councils use, and your licence conditions. It covers the alarm system, fire doors and the escape route, and should be reviewed at least yearly. BritCertify assesses London HMOs from £149 inc. VAT, with the report typically emailed the same day.
Why does an HMO need a fire risk assessment?
Because the Fire Safety Order 2005 applies to the common parts of every HMO, and because several unrelated households sleeping under one roof raises the fire risk compared with a single-family home. Each tenant brings their own cooking, heaters, chargers and habits, and nobody controls the whole house the way a family would.
Two other sets of rules sit alongside the Order:
- The Management of Houses in Multiple Occupation (England) Regulations 2006 require the manager to keep fire alarms and escape routes maintained and in good order.
- HMO licensing. Mandatory licensing applies where five or more people form two or more households, and many London boroughs run additional or selective licensing that catches smaller shared houses. Licence conditions often set specific alarm, fire door and certificate requirements, so check your borough’s conditions.
What is LACORS guidance and how do London councils use it?
LACORS ‘Housing – Fire Safety’ (2008) is the national guidance London councils use as their benchmark when they judge whether an HMO’s fire precautions are adequate. It is not law in itself, but licensing and enforcement officers refer to it, so an assessment that ignores it is unlikely to satisfy them.
The guidance is risk-based. It sets out worked examples for common layouts, such as a two-storey shared house or a three-storey bedsit house, and describes the alarm system, fire doors and escape route protection it would normally expect for each. Taller houses, bedsits with cooking in the rooms and layouts with inner rooms all need more protection.
Our assessors identify which LACORS example your house is closest to, compare what is installed with what the guidance expects, and explain any gaps. Where your house differs from the example but is still safe, the report sets out why, which is exactly the reasoning a licensing officer will want to see.
What fire alarm system does an HMO need?
Most London HMOs need an interlinked, mains-powered alarm system designed to BS 5839-6, so that a fire anywhere sets off every alarm in the house. The grade and category depend on storeys, layout, how the house is let and what your licence specifies.
| Term | What it means | Where it usually fits |
|---|---|---|
| Grade D1 or D2 | Interlinked mains-powered alarms with a built-in standby battery (tamper-proof in D1, replaceable in D2) | Smaller shared houses |
| Grade A | A control panel with separate detectors, sounders and manual call points | Larger HMOs and bedsit houses, where the guidance or licence requires it |
| LD3 | Detection on the escape route only | The minimum; often not enough on its own in an HMO |
| LD2 | Escape route plus rooms where fire is more likely to start, such as kitchens and living rooms | Frequently specified for shared houses; check your licence |
| LD1 | Escape routes and every room where a fire could start | Higher-risk layouts and bedsits |
Kitchens should have heat detectors rather than smoke detectors, otherwise tenants learn to cover or disable them after every burnt meal. Many London licences also require an annual alarm certificate, which our fire alarm certificate service provides.
Do bedroom doors in an HMO need to be fire doors?
Usually, yes. In London HMOs of three or more storeys, and in bedsit-style lets, LACORS expects bedroom and kitchen doors opening onto the escape route to be 30-minute fire doors with self-closers. In a smaller two-storey shared house, sound, well-fitting solid doors can sometimes be accepted where the alarm system is enhanced. Your licence conditions have the final word.
The door problems we find most often in London HMOs are:
- Self-closers removed or disconnected by tenants who find them noisy.
- Bedroom doors with locks that need a key to open from the inside. Escape doors must open from inside without a key, so we look for thumb-turn locks.
- Intumescent strips painted over, or doors trimmed to clear new carpet.
- Kitchen doors propped open in warm weather.
Where doors are doubtful, a fire door inspection gives you a door-by-door record of what passes and what needs work.
What makes a safe escape route in a shared house?
Every tenant should be able to reach the front door along a route that is protected from fire, kept clear and does not pass through a room where a fire is likely to start.
- Open-plan kitchens. In many London conversions the wall between hallway and kitchen has been removed. If the only way out passes the cooker, the route is compromised.
- Inner rooms. A bedroom reached only through a kitchen or living room is a serious concern and is usually acceptable only with additional measures.
- Loft conversions. A third storey changes the protection expected for the whole house, and escape windows are not a substitute for a protected stair at that height.
- Storage. Bikes, bins, suitcases and mattresses left behind by departing tenants are among our most common findings.
- Lighting. Where the route has no natural light, emergency lighting may be needed.
What does the assessor check in an HMO?
We inspect the whole house, not just the hallway, because in an HMO the risk often starts inside a tenant’s room.
| Area | What we look at |
|---|---|
| Bedrooms | Door rating, closer and lock type, detector, portable heaters, extension leads, cooking in rooms |
| Kitchen | Heat detection, fire blanket, door, position of the cooker relative to the exit |
| Escape route | Fire separation, storage, lighting, signage, the final exit door and how it opens |
| Alarm system | Grade and category, interlink test, panel status, logbook, latest certificate |
| Management | Fire information for tenants, test records, how faults are reported and fixed |
What happens after an HMO fire risk assessment?
You receive the full written assessment naming the assessor and a prioritised action plan you can give to your contractor and show your licensing officer. If a licence application is in progress, send the assessment with it; it shows the council you understand the risks in your property.
Deal with high-priority items first, such as keyed bedroom locks, missing closers or a faulty alarm, and keep dated records of the work. Review the assessment whenever tenants change in a way that affects risk, after any building work and at least every 12 months. For more on how HMO and flat assessments differ, read our guide to fire risk assessments for flats and HMOs.
Prices are £149 inc. VAT for a 1–2 bed HMO or rental home, £199 for 3–4 bed and £249 for 5–6 bed; get a quote for larger houses. Fire risk assessments are carried out by NEBOSH-qualified fire risk assessors, and we hold £5 million public liability insurance.

HMO Fire Risk Assessment: frequently asked questions
Is a fire risk assessment a condition of an HMO licence in London?
In many boroughs it is either requested with the application or written into the licence conditions, and the Fire Safety Order 2005 requires one for the common parts of an HMO regardless. Conditions vary between boroughs and between mandatory, additional and selective schemes, so read yours carefully. Tell us the conditions when you book and the assessor will check the house against them.
Who is responsible for fire safety in an HMO, the landlord or the letting agent?
Often both. The Fire Safety Order places duties on whoever controls the premises, and the HMO management regulations place duties on the manager, which can be the landlord or an agent. A management agreement does not remove the owner's own responsibilities. Agree in writing who arranges the assessment, alarm testing, fire door checks and repairs, and keep copies of the records.
Can HMO tenants lock their bedroom doors?
Yes, tenants can have lockable doors, but the lock must open from the inside without a key, usually with a thumb-turn, because the bedroom door is part of the escape route. Keyed deadlocks on the inside are a common finding in London HMOs and are normally recorded as a high-priority action. Hasps and padlocks fitted by tenants should be removed.
Does a small shared flat count as an HMO?
It can. A property can be an HMO with as few as three tenants from more than one household who share facilities such as a kitchen or bathroom. Mandatory licensing starts at five people forming two or more households, but many London boroughs license smaller HMOs through additional licensing. Check with your council; our assessments for 1–2 bed homes start at £149 inc. VAT.
How often should an HMO fire risk assessment be reviewed?
We recommend at least every 12 months for an HMO, and sooner when something changes: new tenants with different needs, a change in how rooms are let, building work, a new alarm system, a fire or a run of false alarms. Some licence conditions set their own review interval. Each review should be dated and recorded alongside the original assessment.
Do I need fire extinguishers in an HMO?
Not automatically. The fire risk assessment and your licence conditions decide. Many councils focus on a fire blanket in each shared kitchen, because untrained tenants are safer leaving the building than fighting a fire. Where extinguishers are provided they must be maintained, which means an annual service under BS 5306-3:2017 and regular visual checks between services.
