Interlinked Smoke Alarms

2021 Legislation, Scotland.

Homeowners and Landlords. Is your property ready?

(Update) The Scottish Government have delayed the new regulations on smoke and carbon monoxide alarms by 12 months due to the impact of coronavirus (COVID-19). The new deadline is now February 2022.


Legislation due to come into effect in February 2021 meant the standard which currently applies to private rented property and new-builds would have been extended to all homes in Scotland.

General Overview

smoke alarm

New Standards

The standard requires:

  • one smoke alarm installed in the room most frequently used for general daytime living purposes

  • one smoke alarm in every circulation space on each storey, such as hallways and landings

  • one heat alarm installed in every kitchen

All alarms should be ceiling mounted and interlinked.

The requirement is to have all alarms interlinked. You may not hear the alarm closest to the fire but, by having an interlinked system, you will be alerted immediately.

Where there is a carbon-fuelled appliance (such as boilers, fires (including open fires) and heaters) or a flue, a carbon monoxide detector is also required which does not need to be linked to the fire alarms.

Why Now?

Following the tragic fire at Grenfell Tower in London, a Ministerial Working Group on Building and Fire Safety was established to review Scotland’s building and fire safety regulatory frameworks. This legislation will ensure that everyone in Scotland has the same level of protection whether they own or rent their home.

The legislation applies to all homes which must meet the minimum standard and, where there is a requirement for specialist equipment for deaf people, this should be installed in addition to the equipment installed to meet the standard.

Any costs will be the responsibility of home owners and landlords. The cost of the alarms will vary according to what you currently have in place and the alarms you choose to install.


The regulations now come into force in February 2022, 12 months after the original planned date due to the difficulties caused by COVID-19.
