FD30 fire doors are mandatory in licensable HMOs. Get the spec, certification or maintenance wrong and your licence is at risk. Here's the current standard.

Introduction
Fire doors are the single most enforced item in HMO licensing. Councils inspect during licence application, renewal and after every fire incident. A non-compliant door is a serious management offence under the HMO Management Regulations 2006. Here's the standard.
What FD30 means
30 minutes of fire resistance under BS 476 part 22 or BS EN 1634-1. Must be tested as a complete door set (door, frame, hinges, intumescent strip) by a UKAS-accredited test house. Certification is documented on the door edge label or a manufacturer's certificate.
Where they're required
All habitable room doors opening onto the escape route — bedrooms, lounges, kitchens (kitchens often FD30S for additional smoke protection). The flat entrance door in a converted HMO must usually be FD60 with intumescent and smoke seals.
Hinges and ironmongery
Three hinges per door minimum, all CE-marked fire-rated. Door closer (Perko, Briton 996 or equivalent) tested for the door type. Latch and lock all CE-marked. Letterboxes on flat doors should be intumescent-lined.
Gap specifications
Maximum 3mm gap around the door at top and sides, 8mm at threshold. Intumescent strip expands 10–15× when heated to 200°C, sealing the gap. Cold smoke seal blocks the lower-temperature smoke that kills before flames arrive.
Self-closers
All FD30 doors must self-close fully into the frame from the open position. Perko chain closers fit invisibly into the top of the door; concealed door closers cost more but look better. Hold-open devices linked to the fire alarm are permitted in commercial-scale HMOs.
Annual inspection
The fire risk assessment must include each door: visible certification, condition of intumescent strips, gap measurements, working self-closer, undamaged surface. Photograph each door annually for the FRA log.
Common failures
Damaged or removed self-closers (the #1 council finding), missing or painted-over intumescent strips, gaps over 4mm where tenants have planed the bottom, blue-tacked notices on doors (compromises certification), missing rating labels. All trigger remediation notices and can suspend the HMO licence.
