Dumbarton's MSP has raised concerns over the cost of fire alarms as new rules come into force too boost their safety.

From February 1, smoke alarms must be interlinked as one of a series of changes brought in after the deadly Grenfell Tower fire nearly five years ago.

But opposition politicians have expressed fears in recent weeks that residents are not fully aware of the rules and they could struggle to pay for them.

It is the responsibility of homeowners to make sure they meet the alarm standards and failure to do so could invalidate their home insurance.

West Dunbartonshire Council (WDC) said the estimated average cost for a three-bedroom home is about £220, which must be met by the owner or private landlords.

But Jackie Baillie MSP said constituents have been quoted up to £400 for the devices. They have also found problems getting installations done, on top of a shortage of equipment.

Ms Baillie said: “This is really worrying news that just days before these laws come into force on February 1, people are being held to ransom by being quoted exorbitant rates for these devices.

“People are unclear about what is required and panicking that they are having to fork out several hundreds of pounds. Many of these people are older and vulnerable and therefore in a position where they feel that they have to pay whatever it takes to get this arranged in time.

“The SNP ruled out a further delay but it is not too late to do the right thing and change their mind.”

The fire alarms rule was already delayed by a year because of the pandemic. But in December, councillors agreed a motion to ask for an 18-month delay to give more time for residents to become aware and get homes up to scratch.

Ahead of the housing and communities committee on February 2, statistics from Scottish Fire and Rescue Service (SFRS) show accidental dwelling fire casualties have doubled from two to four in the past year.

Accidental dwelling fires in the latest figures are also up, though deliberate fire setting is down 43 per cent across West Dunbartonshire.

Council leader Jonathan McColl said this month: "Protecting lives is at the heart of these new regulations.

“So while I appreciate that installing interlinked alarms imposes an additional financial burden for many households, it’s important to remember their purpose – to keep you and your loved ones safe – is priceless.

“Indeed, the potential cost of not making your home compliant would far outweigh this one-off investment if your home insurance becomes invalid.

“Therefore, I would urge every homeowner in West Dunbartonshire to buy and install these alarms before February 1 to protect themselves, their family and their home.”

A total of £500,000 has been provided by the government through Care and Repair Scotland to help disabled and elderly residents install alarms as well as £1million to SFRS to install them in owner-occupied high-risk homes.
