This comes down to fitting a suitable alarm in an appropriate location, and ensuring compliance with legislation and recommended best practice.
For instance, under the Smoke and Carbon Monoxide Alarm (Amendment) Regulations 2022, all private and social landlords must:
- Ensure at least one smoke alarm is equipped on each storey of their homes where there is a room used as living accommodation.
- Ensure a carbon monoxide alarm (CO) is equipped in any room used as living accommodation which contains a fixed combustion appliance (excluding gas cookers).
- Ensure smoke alarms and carbon monoxide alarms are repaired or replaced once informed and found that they are faulty.
If a landlord fails to comply with the updated regulations, the local authority can impose a fine of up to £5,000.
BS 5839-6 is also a key standard for fitting alarms in domestic premises, as it outlines the best practice for compliance with fire safety legislation. This should therefore be considered an authority for private and social housing providers. BS 5839-6 was revised in early 2019, for a simplified guide advising the latest revisions, download our guide below:
Before purchasing a certain type of alarm – whether this be carbon monoxide, heat or a smoke alarm – always ensure it complies with British Standards. For self-contained smoke alarms this is BS 5446 Part 1 (2000) and for an alarm system this is BS 5839 Part 1 (2013).
Also ensure the alarm carries a British or European approval mark, such as a Kitemark. Also, consider its implementation; alarms can be powered by battery or mains, or a combination of both (typically with a battery as a backup for mains power). They can also be interlinked via wireless radio frequency (RF) technology, or be hard wired interlinked.
Different types of fire alarms
There are three key types of alarm on the market, each with separate installation requirements. Inline with NFCC guidance, as of April 2018 FireAngel no longer recommend the use of ionisation alarms.
(1) Optical alarms
These are effective at detecting larger particles of smoke from slow-burning, ‘smouldering’ fires.
Installation: These can be placed near kitchens and in circulation spaces, but not too close to poorly ventilated bathrooms as they are liable to false alarm when exposed to steam.
(2) Multi-sensor alarms
Thermoptek multi-sensor alarms contain two separate sensing elements – optical and heat detection. As the unit monitors for two different by-products of fires (smoke and temperature), its response to all types of fire is vastly improved over traditional single sensor alarms. They are also less prone to false alarms associated with the ionisation and the optical type alarms and hence why UK Fire and Rescue services recommend Multi-Sensor technology.
Installation: Multi-sensor technology eliminates the need to fit separate ionisation and optical alarms, and provides a faster reaction to both fast-flaming and slow smouldering fires in a single alarm. As a result, BS 5839-6 recommends the use of multi-sensor technology in all rooms except the kitchen. Find out more here.
(3) Heat alarms
These can detect an increase in temperature and are insensitive to smoke. Heat alarms are best suited for rooms of high humidity or dust such as kitchens, garages and lofts.
Installation: BS 5839-6: 2019 recommends that heat alarms should be used in kitchens, but should also be part of an interconnected fire alarm system.
Best practice for positioning fire and CO alarms
Smoke and heat
The British Standard BS 5839-6:2019 recommends that smoke and heat alarms be installed:
- On the ceiling, as central as possible in the room
- Sited 300mm from walls and light fittings – this ensures the alarm is out of any ‘dead air’ spaces where the airflow may be blocked
- Placed within 3m of every escape door and bedroom door to ensure audibility
- Positioned between high risk rooms and bedrooms
- For peaked and sloped ceilings – make sure there is a maximum of 600mm vertically down from the apex for smoke alarms, and 150mm vertically down for heat alarms
Heat alarm
Recommended: kitchen, garage, loft
Smoke alarm
Recommended: All circulation areas (e.g. landings), bedrooms and sitting rooms.
Carbon monoxide alarm
The British Standard EN 50292 standard recommends that a CO alarm should be installed:
- Between 1m–3m from all potential sources of carbon monoxide (fuel burning appliances)
- Sited 300mm from walls and light fittings – this is to ensure that they are outside of
any ‘dead air’ spaces that occur in corners and spaces where the airflow may be
blocked - If the fuel burning appliance is in a confined space (e.g. a boiler room) then the
alarm should be sited on the ceiling just outside the room - If there is no fuel-burning appliance, then place the alarm at breathing height e.g. bed’s head height in bedroom
Recommended: In all rooms with fuel burning appliance, bedrooms.
The standard also recommends that CO alarms should not be installed:
- In an enclosed space
- Where it can be obstructed
- Directly above a sink
- Next to a door, window, extractor fan, air vent or similar ventilation opening
- Where the temperature may drop below –5 ºC or exceed 40 ºC

Maintaining alarms after installation
Whilst mechanical and electrical contractors need to ensure alarms are functioning and placed in the most suitable location, alarms also need to be routinely tested and cleaned. As described in BS 5839-6, this testing/maintenance of the property depends on the system grade e.g. an interlinked grade A system with a control panel should test at least one detector a week. It is also recommended to delicately clean your fire alarms with a vacuum cleaner fitted with the soft brush once a month.
For an overview of quick user guides (including what to do when there is low battery beeping or chirping) – see our kitchen safety guidelines for tenants.
Given the majority of housing associations (HA) give new tenants a ‘home-owners pack’ with instructions of how to test fire alarms inside, there is a responsibility on the tenant to do this. Especially, as HA only usually coincide testing of smoke alarms with an annual gas maintenance or electrical check.
As a result of this, it is recommended to install a fire safety system that is high quality, but also easy to use. For instance, by installing FireAngel Specification range of alarms in the home, landlords can be confident that alarms are continually working after fitting as they are mains powered with a tamper proof sealed for life battery backup.
Furthermore, by including an alarm control unit, there is no necessity for physically testing the alarms – all the testing can be done remotely from one centralised location. This is particularly beneficial for social housing, which has a large proportion of vulnerable tenants who may find it difficult (or be unable) to reach the alarms, which are typically located on the ceiling.
