Door Entry and Access Control for HMOs: Landlord Options

Front door: the churn-proof patterns

• The problem keys can't solve: tenant turnover at HMO rates means perpetual key drift — copies uncounted, leavers unreturned, locks re-pinned annually anyway (the flats fob guide's economics, compressed into single houses)
• Fob entry (DESFire, per the cloning catechism): £500–£900 fitted on HMO front doors — revoke leavers in seconds, log entries (ASB dispute gold), trades-window credentials for the boiler man
• Intercom layer: GSM units (£450–£900 per its guide) route door calls to tenant phones flat-free — parcels stop failing, tailgating drops when buzzing-anyone dies; audio suffices for most HMOs (video where the budget smiles)
• Combined panels (fob + GSM directory): the tidy single-unit answer at £900–£1,500 fitted — one survey, one hole pattern, one maintenance line
• Postal/delivery reality: trades buttons with schedules, parcel-safe provisions, and the letterbox question (through-door boxes on FD30S front doors need fire-rated assemblies — the fire-door modification rules reach HMO front doors emphatically)

Room doors: locks, law and the egress line

Room-door security in licensed HMOs balances three masters: tenants' quiet enjoyment (lockable rooms — expected and licensing-favoured), fire egress law (escape without keys — thumb-turns inside, always; deadlocking tenants in is the disqualifying error), and fire-door integrity (FD30S room doors take rated hardware fitted per certification — the hinges/furniture rules apply; closers stay functional per the closers guide, free-swing where slamming wars erupt). The lock menu: keyed-different cylinders (cheap, churn-expensive — re-pinning rituals continue), code locks (£80–£200/room, codes rotate between tenancies, battery admin), and fob/RFID room locks (£150–£400/room — escutcheon-class, instant re-permission, entry logs where disputes brew; the Salto-pattern miniaturised for HMOs). Portfolio logic favours fob estates: one credential per tenant spanning front door + room + bin store, revoked once at checkout — the standardisation dividend from our landlord alarm guide, doored.

Costs, licensing and the management rhythm

Per-property money: front-door fob + GSM combined: £900–£1,500; room fob-locks × 5: £750–£2,000; full HMO entry estate: £1,700–£3,500 — against which key-chaos carries locksmith drips, void-day losses (re-securing between tenancies), and dispute opacity forever. Licensing/compliance notes: entry systems feature in licensing conversations where security/ASB history exists (logs help), fire-egress compliance is inspected (thumb-turns, FD30S hardware — failures here are licence findings per the HMO fire guide), and the management regs' good-order duties cover entry kit explicitly. Operating rhythm for landlords/agents: checkout = revoke + reissue (minutes, remote on cloud-managed estates), annual service folding entry hardware into the property's compliance visit (the bundled-visit economics across our HMO work), and documentation per property (credentials register, programming records) so portfolio handovers don't orphan systems. The HMO security stack — entry, alarms (per its guide), compliant detection — quotes best as one survey; landlords get one file, one renewal rhythm, one number.
