Landlord Legal Requirements — What You Need to Know
The Smoke and Carbon Monoxide Alarm (Amendment) Regulations 2022 require landlords in England to ensure a smoke alarm is fitted on every floor of the property where there is a room used as living accommodation, and a carbon monoxide alarm in every room containing a fixed combustion appliance (excluding gas cookers). Landlords must ensure all alarms are in working order at the start of each new tenancy.
These regulations apply to all residential tenancies in England including private rentals, HMOs, and short-term lets. Local councils have enforcement powers and can issue remedial notices requiring compliance within 28 days. Non-compliance can result in a civil penalty of up to £5,000.
We provide a written completion record for every property we service — noting each alarm location, the test result, battery replacement date, unit model and expiry date. This documentation supports your compliance file and provides evidence of due diligence if a compliance issue is ever raised.
Alarm Types and Placement
Smoke Alarms — Where Required
One on every floor where there is a habitable room. In practice: hallways on each storey, and landing or bedroom corridors. Optical alarms are recommended for sleeping areas as they respond better to slow smouldering fires. Ionisation alarms are better for kitchens where fast-flaming fires are more likely, but are more prone to false alarms from cooking.
CO Alarms — Where Required
In every room containing a fixed combustion appliance — gas boiler, gas fire, log burner, oil-fired appliance. Not required for gas cookers under the current regulations, but recommended. CO alarms should be placed at head height approximately 1–3 metres from the appliance.
10-Year Sealed Battery Units
For landlords who want to minimise ongoing maintenance, 10-year sealed battery alarms are available. The sealed battery matches the unit's operational life, eliminating annual battery replacement. The unit is replaced rather than re-batteried at end of life.
Heat Alarms for Kitchens
Standard smoke alarms in kitchens trigger frequently from cooking. A heat alarm is better suited to kitchen use — it responds to temperature rise rather than smoke and is less prone to nuisance activations while still providing fire detection.
Portfolio Servicing for Landlords
For landlords managing multiple properties, we offer portfolio servicing — a scheduled programme that keeps all your properties compliant without you tracking each individually. We maintain a service record for your entire portfolio, alert you when units are approaching expiry, and attend at the start of new tenancies on request.
Schedule set once
We track service dates across your portfolio and contact you when visits are due — you don't need to manage the calendar.
Digital records per property
A signed completion record is issued after every visit, listing each alarm's location, test result and battery replacement date. Accessible whenever you need them.
Tenancy changeover visits
On request, we attend at the start of each new tenancy to test all alarms and confirm compliance before the tenant moves in — satisfying the statutory obligation.

Our Process
What You Can Expect
From your first call to the finished job, here is how our smoke & co alarm servicing service works.
Tell us the property address, number of floors, approximate number of alarms and whether any are known to be faulty or expired. For landlords managing multiple properties, a portfolio visit schedule is available.
We attend at the agreed time and test every alarm at the property — activating each unit and confirming it responds correctly.
Batteries are replaced as standard on every unit. Any alarm that fails the activation test, shows signs of physical damage or is past its manufacturer expiry date is flagged for replacement.
Replacement units are fitted at the correct location and type for the room, with batteries installed and tested before we leave.
A written completion record is provided for every property — listing each alarm, location, test result, battery replacement date and unit expiry date.
Insider Advice
Helpful Hints & Tips
Test alarms at the start of every tenancy — not just annually
The 2022 regulations require alarms to be working at the start of each new tenancy, not just once a year. A mid-tenancy inspection visit from Multrex covers this requirement and provides a documented record.
Replace units at 10 years — not just batteries
Smoke and CO alarm sensors degrade over time. Most manufacturers specify a 10-year operational life for the unit itself, regardless of battery condition. Check the manufacture date on the back of each alarm.
Don't paint over alarms
Paint clogs the detection chamber and can prevent the alarm from responding. If an alarm has been painted over, it needs replacing — it is no longer fit for purpose regardless of battery condition.
