Scottish Legislation 2022 – Interlinked Smoke and Heat Alarms

What are the Scottish Smoke and Heat Alarm Regulations?

Announced in February 2019 and in effect from February 2022 (delayed from 2021), all homes in Scotland must be fitted with interlinked smoke and heat alarms. Most homes will also need a carbon monoxide alarm.

Do the new Smoke and Heat Alarms regulations affect me?

This applies to all homes in Scotland regardless of the type or age of the property. In contrast to normal updates to building regulations or British Standards, the new law will apply to all types of homes. This also includes older domestic properties, new builds and homes that have been extended or renovated before or after the rules come into effect. It is the property owner’s responsibility to ensure that the appropriate alarms are correctly installed.

Which and how many alarms do you need to be compliant with the new Scottish Regulation?

By February 2022, every Scottish home will need 1 x SMOKE ALARM in the room you spend most of the day; usually, your living room, or it could be your office if you work from home.
1 x SMOKE ALARM in every circulation space on each story, such as hallways and landings
1 x HEAT ALARM in the kitchen

All smoke and heat alarms should be mounted on the ceiling and be interlinked. If you have a carbon-fuelled appliance, like a boiler, gas fire, or gas hob, you must also have a CARBON MONOXIDE DETECTOR. This does not need to be interlinked with the fire alarms, but to comply with the legislation, battery-powered alarms must come with long-life tamper-proof batteries.  This means you can’t remove the batteries for the product’s lifetime.

What the alarms must have to comply with the regulation:

BATTERY-POWERED ALARMS must be sealed and tamper-proof units and have long-life lithium batteries for up to 10 years. If you also need a carbon monoxide alarm and if it is battery-operated, it must also have a sealed, tamper-proof battery for the duration of its lifespan.

Further, you need to ensure that each alarm complies with the following standards:

  • Smoke Alarms: BS EN14604:2005
  • Heat: BS 5446-2:2003
  • Carbon monoxide: British Kitemark EN 50291-1

You may be able to fit these types of alarms yourself, and they do not need an electrician. If you chose MAINS POWERED ALARMS, they must be fitted by a qualified electrician and must be replaced every 10 years. You may also need to redecorate after fitting/replacing them.
