What HMO licence fire safety conditions actually require

Alarm grades for a three storey shared house
When Sutton Council sets hmo fire requirements sutton council landlords must follow, the alarm specification is usually the first condition listed. For a three storey HMO the expected standard is typically a Grade D1 system. A shared house alarm grade d1 means mains powered detectors with a battery backup, wired so that if one head detects smoke every sounder in the building activates.
The system needs heat detectors in kitchens and smoke detectors in hallways, landings and each bedroom. A specialist firm installs the wiring and commissions the panel. The licensing officer will want to see the commissioning certificate as proof that the correct grade has been fitted. If the existing alarms are battery only or not interlinked they will need replacing before the licence is granted.
Fire safety for landlords sutton starts with getting this right early, because rewiring takes longer than fitting doors. A separate specialist can carry out an [HMO fire risk assessment](/fire-safety/hmo-fire-risk-assessment-sutton) to confirm which zones need coverage.
Which rooms need fire doors under the licence
HMO fire door rules London councils enforce generally require thirty minute fire resisting doors on every room that opens onto the escape route. In a typical converted house in Sutton, that means each bedroom, the kitchen and any lounge used by tenants needs a complete door set.
Bathrooms and small cupboards are sometimes exempt, but the licensing officer makes the final call based on the layout. Each door must have intumescent strips, cold smoke seals, three hinges and a self closing device that shuts it fully from any angle. A specialist firm inspects these components and records the gaps around the frame during a [fire door inspection](/fire-safety/fire-door-inspection-sutton). You can read more about [what gets checked on a fire door](/duties/fire-doors-what-gets-checked) before an inspection takes place.
Tenants do not normally need to move out while doors are hung. The work happens room by room during the day. Because of the noise and dust, it helps to schedule installations when people are at work or studying. The specialist coordinates access directly with occupiers.
Emergency lighting and keeping escape routes clear
An hmo emergency lighting requirement applies to the escape route rather than individual bedrooms. Even a small shared house needs maintained or non maintained bulkheads along the hallway and stairs so tenants can find the exit if the power fails during a fire. Larger purpose built blocks follow different standards but the principle is the same: light the path to the front door.
Escape routes must stay clear at all times. Bikes, shoes and bin bags left in a corridor reduce the usable width and give the fire somewhere to start. If the officer visits and finds the hallway blocked they record it as a breach of the licence conditions. Repeated breaches can lead to enforcement action or licence revocation.
A specialist firm can advise on [emergency lighting testing](/latest/emergency-lighting-testing-in-sutton-communal-areas) schedules so the batteries never fail silently. Keeping bins away from the entrance also reduces [arson risk](/latest/arson-risk-at-sutton-premises-gates-bins-and-lighting), which licensing teams look at closely.
Evidence the licensing officer asks to see
During a licensing officer fire inspection the evidence requested goes beyond a quick walk round. The officer wants paperwork that proves the physical work was done correctly. Expect them to ask for the alarm commissioning certificate, the electrical installation condition report and certificates for each fire door set installed.
They will also want to see a current [fire risk assessment](/fire-safety/fire-risk-assessment-sutton) completed by a competent person. If the building is a conversion the officer might ask for a [compartmentation survey](/fire-safety/compartmentation-survey-sutton) to check that hidden voids above ceilings and behind boxing have been sealed against smoke spread.
Once the licence is issued it usually carries a deadline for completing any outstanding conditions. That period is often three to six months but the decision letter states the exact date. Missing it leaves the property operating without valid licence conditions being met. A [nominated person service](/fire-safety/nominated-person-service-sutton) can manage the paperwork and deadlines so nothing slips past the date.
Reading the signs in your shared house
A mark or missing part might be harmless wear or a reason the licensing officer refuses the application. Knowing the difference stops unnecessary worry and wasted money.

- Gaps bigger than 3mm around a bedroom door
- Smoke will pass through in a fire. A specialist measures the gaps and fits new intumescent strips or adjusts the hinges to bring them within limits.
- No battery backup on the hallway smoke alarm
- The system does not meet the expected grade. An alarm specialist replaces the heads with mains units that include a sealed standby battery.
- Dark hallway when the main lights go off
- Escape lighting is missing or the battery has failed. A specialist tests the charge duration and fits new bulkheads where the route needs them.
- Shoes and boxes stacked near the front door
- The escape route width is reduced below what the licence allows. Clearing the space is immediate; a management plan keeps it clear long term.
- Self closer that slams or stops halfway
- The door will not hold back smoke properly. A specialist adjusts the arm speed or replaces the device so it latches shut every time.
What changes the cost of meeting conditions
Every shared house has a different layout, age and state of repair, so the work needed varies from one building to the next.
- Number of rooms needing doors
- Each door set requires removal of the old leaf, fitting new frames and hanging hardware, adding labour and materials per room.
- Existing wiring for the alarm
- If no cables run between floors the specialist chases walls or uses surface trunking, which takes longer than connecting to existing circuits.
- Age of the building
- Older conversions often have uneven frames and hidden voids that need extra sealing before compartmentation meets the required standard.
- Length of the escape route
- A longer hallway and more stair flights need additional emergency lighting points to maintain the required lux level throughout.
The specialist explains the full cost of the particular job before anything is agreed.
