Tenant Reported Faulty Smoke Alarm: Landlord Repair Obligations

Before October 2022, there was no explicit statutory obligation on landlords to repair a faulty alarm during an ongoing tenancy. The 2022 amendments changed that. Regulation 4(1)(c) now requires you to repair or replace a faulty smoke or CO alarm "as soon as reasonably practicable" once notified by the tenant or their representative.

What "As Soon as Reasonably Practicable" Means

The regulations set no fixed hour-count deadline: they require repair or replacement "as soon as reasonably practicable." Local authority guidance treats alarm failures as urgent hazards, so assess the fault promptly and arrange the repair or replacement in line with that statutory standard.

A total CO alarm failure in a room with a gas boiler is treated more urgently than a chirping low-battery warning on a secondary smoke alarm. If a repair is delayed by an access refusal or another practical issue, document the reason and the steps you took to resolve it.

The Fault Response Process

When a tenant reports a faulty alarm — by text, email, phone, or letter — you need a systematic response:

Step 1: Acknowledge in writing. Reply to the tenant confirming you've received the report and stating when you'll attend. Even if the initial report comes by phone, send a written follow-up (email or text) so you have a timestamped record. This is your evidence that you responded promptly.

Step 2: Triage the issue. Ask the tenant what's happening. A continuous chirping every 30-60 seconds usually means a low battery. In Grade D2 or F2 units, the standby battery is user-replaceable; check the manufacturer's instructions for the correct battery type. A complete silence (no test-button response) or a unit that's been removed from the ceiling needs your direct intervention. In units with an integral, non-user-replaceable battery (including Grade F1 and some Grade D1 models), follow the manufacturer's instructions; if the battery cannot be replaced separately, replace the unit.

Step 3: Arrange access. Section 11(6) of the Landlord and Tenant Act 1985 gives a landlord a right to enter at reasonable times to inspect the property's condition or carry out repairs after giving at least 24 hours' written notice. Specify the date, time, and purpose. The notice does not authorize forced entry.

Step 4: Repair or replace. Attend the property, fix the fault (replace battery, replace unit, or re-mount a dislodged alarm), and perform a push-button test on the repaired or replacement unit.

Step 5: Document everything. Record the date and nature of the fault, when you acknowledged it, when you arranged access, when you attended, what you did, and the result of the retest. Have the tenant sign off that the alarm is now working.

When the Tenant Refuses Access

If the tenant refuses access after notice, do not force entry. Section 11's notice does not authorize forced entry, even when the repair is safety-related.

Your process when access is refused:

1. Send a second written request with flexible alternative times
2. Explain in the letter why the repair is legally required and safety-critical
3. If refusal persists, log every notice, email, text, and call attempt with dates
4. Notify your local authority's private-sector housing team that you've been unable to access the property despite multiple documented attempts

A documented access log doesn't give you an automatic exemption from enforcement — but it demonstrates "reasonable steps" if the council later investigates why the fault wasn't resolved.

The Battery-Removal Problem

One particularly fraught scenario: the tenant removes the alarm battery (or the entire alarm) because of nuisance sounding — often triggered by cooking steam, shower vapour, or a poorly positioned kitchen alarm. This puts you in an awkward position: the alarm isn't working, but the cause isn't a mechanical fault.

Your response should be the same as for any fault — treat the alarm as non-functional and attend to restore it. Consider whether the alarm is poorly positioned (too close to the cooker or bathroom) and reposition it if needed. Address the nuisance-sounding cause rather than leaving the tenant without a working alarm.

The statutory duty to repair or replace a faulty alarm once notified still applies. Dated records of the alarm's condition and the tenant's interference are relevant to the council's assessment.

The Cost Question

The Tenant Fees Act 2019 prohibits charging tenants for routine safety compliance, testing, or normal wear-and-tear replacements. You cannot invoice the tenant for replacing a smoke alarm that expired naturally or failed mechanically.

You can seek a tenancy-deposit deduction for tenant-caused damage or loss beyond fair wear and tear, supported by evidence such as a check-in inventory and repair records. Normal expiry or mechanical failure is not tenant damage; the deposit scheme's dispute process determines whether a deduction is justified.
