Alarms to meet Scottish Fire Alarm Regulations

Starting from February 2021 the new law in Scotland will require all homes (owned or rented) to have interlinked Smoke and Heat alarms installed. Where there is a carbon-fuelled appliance (such as boilers, fires and heaters) or a flue, then a Carbon Monoxide alarm is also required.


What type of alarms meet the new legislation? | How many alarms do I need?


The below selection of alarm ranges are all suitable to meet the new Scotland Regulations which take effect from February 2021:

The new law details specific requirements for the types of alarms you can use as not every alarm on the market is suitable to meet the new legislation. The following minimum requirements apply:

Power Supply: All alarms must be either mains-powered or powered by a sealed long-life lithium battery which is tamper-proof. Any alarms which are only powered by replaceable batteries (e.g. AA, 9v alkaline etc) are not compliant with the legislation.

Interlink: All Smoke and Heat alarms must be interlinked to form a connected and synchronised system. This can be achieved either through a hard-wire interlink (an interconnection cable which runs through all alarms) or via wireless radio connection. Stand-alone alarms which cannot be interlinked are not allowed. Carbon monoxide alarms are not required to interlink with the Smoke and Heat alarms, but it is recommended that this is done where possible to offer the highest level of protection.

By February 2021 all homes in Scotland will be required to have the following:

  • One smoke alarm - installed in every circulation space on each floor level, such as hallways and landings
  • One smoke alarm - installed in the room most used for general daytime living purposes
  • One heat alarm - installed in every kitchen space
  • One carbon monoxide alarm - installed in every room with a carbon-fuelled appliance (such as boilers, fires, stoves and heaters) or a flue

All alarms should be ceiling mounted and interlinked so that when one alarm is activated, all alarms in the property will sound to provide a synchronised warning throughout.

Carbon Monoxide alarms where fitted do not need to be interlinked with the smoke and heat alarms, however it is recommended that this is done where it is possible to provide the highest level of protection.
