Smoke Alarms, Heat Detectors and Home Safety: What Every Glasgow Homeowner Needs to Know

Scotland's fire alarm standard changed in February 2022, and it applies to every home, not just rental properties - which means a lot of owner-occupied Glasgow homes are still running on the older standard without realising the law has moved on.

What the law actually requires

Every home in Scotland needs one smoke alarm in the room most used for general daytime living, one smoke alarm in every hallway or landing used as an escape route, and one heat alarm in the kitchen. All of these need to be interconnected, so that when one triggers, they all sound. If the property has a fuel-burning appliance - a gas boiler, an open fire, a wood burner - a carbon monoxide alarm is required in that room too.

Why "interconnected" is the part people miss

A lot of homes have working smoke alarms that simply aren't linked together - which meets a much older standard, not the current one. If a fire starts in a kitchen and the hallway alarm two rooms away doesn't sound because it's a separate, unlinked unit, that's exactly the gap interconnection is designed to close, particularly for anyone asleep or in another part of the house.

This isn't just a landlord rule

It's a common assumption that this standard only applies to rental properties, but it applies to every home in Scotland regardless of tenure. Owner-occupiers aren't legally required to retrofit it on the same enforcement timeline landlords face, but the safety case for doing so is identical either way.

Hardwired versus interlinked battery alarms

Interconnection can be done with mains-wired alarms linked by cable, or with modern radio-interlinked battery alarms that communicate wirelessly - both meet the standard. Mains-wired is the more permanent option and usually makes sense during a rewire or renovation when cabling is already being run; radio-interlinked alarms are a practical retrofit option for a property that isn't otherwise having electrical work done.

Getting it checked and installed properly

Alarm positioning matters as much as the alarms themselves - too close to a kitchen extractor and a smoke alarm nuisance-trips constantly, too far from an escape route and it doesn't do its job. A proper installation accounts for this rather than just fitting alarms to the letter of the room count.
