If you own or rent out a home in Scotland, the law already requires interlinked smoke alarms — not a single stand-alone alarm on the landing, but a set that talks to each other, so if one goes off, they all go off. This has applied to every home in Scotland since 1 February 2022. If your flat in Dennistoun or your rental in Shawlands still has one battery alarm from a decade ago, it is not compliant, and the fastest way to fix that is a qualified electrician who can fit and certify interlinked alarms in a single visit.
Browse Glasgow electricians who fit interlinked smoke alarms → GlasgowTrader lists 325 electricians across the city, from Bearsden to Govanhill, many of whom carry out alarm installs and compliance checks alongside rewiring and EICR work.
What “interlinked” actually means
Interlinked alarms are wired together, or connected wirelessly by radio signal, so that when one alarm detects smoke or heat, every alarm in the property sounds at the same time. The point is simple: you should be able to hear a warning no matter which room you’re in when a fire starts, not just the room where the alarm happens to be.
This is different from the old setup in a lot of Glasgow tenements and older homes, where each alarm works on its own and only the people near it hear it go off. A single stand-alone alarm in a hallway is not enough to meet the current standard, even if it’s working perfectly and in date.
Smoke alarm regulations Scotland: what every home needs
The requirement was introduced under the Housing (Scotland) Act 1987 (Tolerable Standard) (Extension of Criterion) Order 2019, and came into force on 1 February 2022 (it was originally due in February 2021 but pushed back a year because of the pandemic). It applies across all tenures — owner-occupied, private rented, and social housing — and every home in Scotland is expected to meet it now, not just new-builds or homes sold since 2022.
According to gov.scot’s official guidance, every home needs:
- One smoke alarm in the living room, or whichever room you use most.
- One smoke alarm in every hallway and landing (every circulation space on each storey).
- One heat alarm in the kitchen.
- All of the above ceiling-mounted and interlinked, so one going off sets off the rest.
- A carbon monoxide detector in any room with a carbon-fuelled appliance — a boiler, gas fire, or wood burner, for example. The CO detector does not need to be interlinked with the smoke and heat alarms.
If you’ve got an open-plan living space — say a combined hall and living room — one alarm can cover it, as long as it’s within 7.5 metres of every point in the room (use a heat alarm if the space includes a kitchen area).
This is the “smoke alarm regulations Scotland” standard in full. It sits alongside, not instead of, any separate requirements landlords already have for private rented property under the wider Repairing Standard.
Who’s responsible: homeowners, council tenants, private tenants
Responsibility follows who owns the property, not who lives in it:
- Homeowners are responsible for meeting the standard, and for paying for it, in their own home.
- Council and housing association tenants — your landlord is responsible for having interlinked alarms in place.
- Private tenants — your landlord must provide interlinked fire and smoke alarms as part of your tenancy. This applies to every private tenancy, regardless of when it started.

For private rented property, interlinked alarms form part of the statutory Repairing Standard. If a private landlord hasn’t complied, a tenant can apply to the First-tier Tribunal for Scotland (Housing and Property Chamber), and it’s the tribunal that decides what happens next.

For owner-occupiers, a home that falls below this standard is treated as below the Tolerable Standard — the basic legal minimum for house condition in Scotland — and local authorities have statutory powers to require an owner to carry out the work.
What it costs
According to gov.scot, fitting your own alarms — tamper-proof, long-life lithium battery interlinked smoke and heat alarms plus a CO detector — costs around £220 in total for an average three-bedroom house (three smoke alarms, one heat alarm, one carbon monoxide detector), if you fit them yourself. The same guidance is clear that getting an electrician to fit them will cost more, though it doesn’t put a figure on it.
Hardwired interlinked alarms (as opposed to radio-linked battery ones) usually mean lifting floorboards or running cable between rooms, which is a job better suited to an electrician than a DIY fit — particularly in an older tenement flat where the wiring and joists aren’t always straightforward.
Booking a Glasgow electrician to fit or check your alarms
Most electricians on GlasgowTrader who handle domestic rewiring, EICRs, and consumer unit work will also fit and certify interlinked smoke and heat alarms — it’s a routine part of the job, not a specialist call-out. When you contact one, it’s worth asking:
- Do you fit interlinked smoke and heat alarms to the current Scottish standard?
- Would you recommend wireless (radio-linked) or hardwired alarms for my property?
- Can you also fit or check the carbon monoxide detector at the same visit?
- Will I get anything in writing confirming the work meets the standard?
Whether you’re in a sandstone tenement in Dennistoun, a semi in Bearsden, or a new-build flat by the Clyde, the fitting process is broadly the same: the electrician checks what alarms you’ve already got, works out where new ones or interlinking need to go, and fits and tests the system in one visit for most homes. If you’re on the Southside, our guide to electricians in Cathcart is a good place to start finding someone local for the job, or see the full Southside electricians guide for Giffnock, Clarkston and Muirend as well.

Landlords: this sits alongside your other compliance jobs
If you’re a landlord, interlinked smoke alarms are one part of a wider set of annual and ongoing legal obligations in Scotland — alongside things like your gas safety certificate (CP12), which has to be renewed every 12 months if the property has any gas appliances. If you haven’t got both sorted, it’s worth booking them together where you can, especially if you manage more than one property. HMO landlords have annual appliance checks on the same list — our PAT testing guide covers what that involves and costs.
