Smoke alarms are a crucial component of home safety, providing early warning in the event of a fire and allowing inhabitants to take necessary actions to prevent damage or injury. In Scotland, changes to the law have made interlinked smoke alarms in every home obligatory, further strengthening the commitment to fire safety following tragedies such as the Grenfell fire in London in 2017.

Under the new legislation introduced in February 2022, Scottish homes are required to have an interlinked fire and smoke alarm system installed. This means that if one alarm goes off, all the connected alarms will also sound, ensuring that residents are alerted to potential danger, regardless of where they are in the house. Specific requirements include having a smoke alarm in the main living area, a smoke alarm in each circulation space on every storey, such as hallways and landings, and a heat alarm in the kitchen. All of these alarms must be mounted on the ceiling and be interconnected for maximum effectiveness and safety.

While this change in the law seeks to boost fire safety measures in Scottish homes, residents should continue to be vigilant and undertake routine maintenance checks on their alarms to ensure they remain in good working order. With these new regulations now in place, Scotland aims to reduce the risk of fire-related incidents and promote a safer living environment for all of its residents.

Smoke and Heat Alarms Requirements


In Scotland, the legislative requirements for smoke and heat alarms have been updated. As of February 1, 2022, an amendment to the statutory tolerable standard under section 86 of the Housing (Scotland) Act 1987 necessitates satisfactory detection and warning provisions for fires or suspected fires in all houses, regardless of tenure.

Smoke Alarm Types

For effective smoke and heat identification, it is crucial to have the appropriate alarm types installed. Smoke alarms can be classified into two main categories: mains-wired and sealed battery. Both types must be compliant with the British Kitemark standard.

Interlinked alarms are a vital component of a home’s fire safety system. These alarms communicate with each other via radio frequencies. If one alarm detects a fire, all linked alarms will sound, ensuring prompt and widespread warning throughout the property.

Alarm Placement

Proper placement of smoke and heat alarms is key to maximising their effectiveness. Scottish regulations require the following installations:

  • One smoke alarm in the room you spend most of the day, typically the living room
  • One smoke alarm in every circulation space on each storey, such as hallways and landings
  • One heat alarm in the kitchen

All smoke and heat alarms must be mounted on the ceiling and be interlinked for optimal coverage. Additionally, if a carbon-fuelled appliance (e.g., boiler, fire, heater, or flue) is present in any room, a carbon monoxide detector must be installed in that room, although it does not need to be linked to the fire alarms.

Property owners, homeowners, landlords, and housing associations are responsible for ensuring compliance with these regulations. Failure to do so may result in penalties from local authorities or councils, and potential implications for home insurance policies.

Exceptions may be made for those receiving a state pension, pension credit, or other financial assistance, as the Scottish Fire and Rescue Service may offer support in such cases.

Carbon Monoxide Alarms


From February 2022, the smoke alarm, heat alarm, and carbon monoxide (CO) alarm regulations in Scotland have changed. All homes with a fuel-burning appliance, such as a boiler or wood-burning fireplace, must have a carbon monoxide alarm installed. Interlinked smoke and heat alarms are also required to provide better protection and safety.

Carbon Monoxide Detector Types

There are various types of carbon monoxide detectors available. Here are a few common options:

  • Battery-powered detectors: These detectors operate on batteries and can be placed anywhere within the home, making them highly versatile.
  • Mains-powered detectors with battery backup: These detectors are powered by your home’s electricity and come with a backup battery to ensure continuous operation in case of a power outage.
  • Digital display detectors: These detectors have digital screens that display the current level of carbon monoxide in the area, helping you monitor levels over time.
  • Smart detectors: These detectors can connect to a home automation system or an app, sending notifications when carbon monoxide levels cross a certain threshold.

Appliance Risks

Carbon monoxide (CO) is a dangerous gas produced when carbon-fuelled appliances, such as gas boilers, wood-burning fireplaces, or flues are not working correctly or poorly ventilated. The risk of CO poisoning increases with improper installation, poor maintenance, or faulty appliances. In Scotland, the Scottish government has made it mandatory for all homes with carbon-fuelled appliances to have carbon monoxide alarms installed to prevent CO-related accidents.

Remember to regularly check and maintain carbon monoxide alarms, and always have carbon-fuelled appliances serviced by qualified professionals. These precautions ensure the safety of your household and adherence to the regulations set by the Scottish government.

Interlinked Alarm Systems

Interlinked fire and smoke alarms have become mandatory in Scotland, providing increased safety and protection for homeowners. These interconnected systems ensure that if one alarm goes off, all the alarms in the house will activate, allowing occupants to quickly become aware of any potential fire hazards.

The new law requiring every home in Scotland to have interlinked alarms was introduced as a response to the tragic Grenfell Tower fire in London in 2017. The regulations apply to all Scottish homes, regardless of the type of property or whether it is rented or owned.

With interlinked alarms, you can have peace of mind knowing that you will hear the alarm even if you are in a different part of the house. This increases the chances of early detection and timely evacuation in the event of a fire, potentially saving lives.

To comply with the new law, homeowners must ensure that their existing smoke and heat alarms are interconnected by February 2022. In addition to smoke alarms, carbon monoxide alarms and heat alarms must also be installed to provide comprehensive fire safety coverage.

In summary, interlinked fire and smoke alarms are a vital part of fire safety measures in Scottish homes. By following these regulations, homeowners can help ensure the safety of their families and properties while also complying with the law.

Property Owners and Landlords Responsibilities


Property owners and landlords in Scotland have a legal duty to ensure their properties meet the new fire and smoke alarm standards in accordance with the Housing (Scotland) Act 2006. These standards require:

  • 1 smoke alarm in every circulation space on each storey, such as hallways and landings
  • 1 heat alarm in the kitchen
  • All smoke and heat alarms to be mounted on the ceiling and interlinked
  • A carbon monoxide detector, if a carbon-fuelled appliance is present

Both mains-wired alarms and sealed battery alarms can be used to meet the requirements.


Non-compliance with the fire and smoke alarm standards can result in enforcement actions from local authorities. Additionally, if a property does not meet the required standards, it may be reflected in the home report, potentially affecting the property’s value and saleability.

Support for Older and Disabled Homeowners

Recognising the potential challenges faced by older and disabled homeowners, the Scottish government has initiated some support measures for eligible individuals. To be eligible for support, homeowners must be:

  • Aged 65 or above
  • Living in a property in council tax bands A to C
  • Disabled or in a support group for Employment and Support Allowance

These measures aim to reduce the risk of injury or death from fires and ensure that all homeowners, regardless of age or disability, can benefit from the improved safety standards introduced after incidents such as the Grenfell fire.

Local authorities may provide additional assistance in the installation of appropriate fire and smoke alarm systems, including both mains-wired and sealed battery alarms.

In summary, property owners and landlords in Scotland have a legal responsibility to comply with the new fire and smoke alarm standards. Non-compliance may result in penalties and enforcement actions from local authorities. Support is available for eligible older and disabled homeowners to ensure that all Scottish homes can benefit from these improved safety measures.

Scottish Government Support and Funding

Funding Schemes

The Scottish Government has provided extra funding for smoke alarms ahead of the new law requiring all homes in Scotland to have interlinked fire alarms. A total of £500,000 has been allocated to Care and Repair Scotland, which doubles the funding already given to the organisation. The aim of this funding is to help older and disabled people install the necessary alarms in their homes.


The financial support offered by the Scottish Government focuses on elderly and disabled individuals who require assistance in meeting the costs of the new smoke alarm laws. The £500,000 fund has helped approximately 800 people so far, providing them with the necessary alarms and installation services.

Housing Associations and Councils Support

Social landlords, including housing associations and councils, play a crucial role in ensuring that their properties comply with the new regulations. The law mandates that as of 1 February 2022, every home in Scotland must have interlinked fire alarms, which means if one alarm goes off, all the alarms will activate. To achieve this, housing associations and councils are responsible for providing and installing the required alarms in their properties.

By offering financial support and resources, the Scottish Government aims to increase fire safety awareness and encourage the widespread implementation of interlinked alarms in homes. This measure was taken following the Grenfell disaster to further enhance public safety and prevent similar incidents from occurring in the future.

Alarm Installation and Maintenance

Installing and maintaining smoke alarms in your properties is crucial to ensuring a fire-safe home. Following Scotland’s new smoke alarm law that came into force in February 2022, all homes now require interlinked smoke and heat alarms. This means that when one alarm senses danger, all the alarms will sound, alerting everyone in the property.

As a property owner, it’s essential to have these alarms installed by a qualified electrician to ensure the system functions correctly and complies with current regulations. Engaging professional tradespeople will not only save you time but also guarantee expertise in handling installations and necessary safety precautions.

During the installation process, electricians can advise on appropriate maintenance measures to reduce the likelihood of false alarms. Regular maintenance includes:

  • Testing alarms monthly by pressing the test button.
  • Cleaning the alarms with a vacuum cleaner at least every six months to remove dust.
  • Replacing batteries as per the manufacturer’s recommendations or when the alarm signals a low battery.
  • Replacing the entire unit if it’s beyond the manufacturer’s recommended lifespan or faulty.

It’s crucial to conduct regular fire drills within your property. This practice ensures that all occupants are familiar with the alarms’ sound, improving their reaction time during a real fire event. It also serves as an opportunity to test the functionality of the entire interlinked system.

In the social rented sector, landlords must follow the fire safety regulations as set by the Scottish Government. This includes ensuring that adequate and properly functioning smoke and heat alarm systems are in place.

By adhering to these regulations and engaging qualified electricians for alarm installation and maintenance, property owners in Scotland can maintain a high standard of fire safety, providing a secure environment for their occupants.

Additional Information

According to Scottish government regulations, every home in Scotland must now have interlinked smoke alarms to improve fire safety. Housing Secretary Shona Robison has emphasised the importance of these new regulations in helping to save lives in the event of a fire.

Interlinked smoke alarms ensure that when one alarm detects smoke or fire, all alarms throughout the home are triggered, providing better protection for residents. These devices should be installed in the living room, hallways, landings, and there should also be a heat alarm in the kitchen, all mounted on the ceiling. Using tamper-proof long-life lithium battery alarms is recommended due to their longevity and reliability.

Compliance with the new smoke alarm regulations is crucial for homeowners, as it may impact their home insurance policies. Not adhering to the regulations may result in penalties, although the Scottish government has assured residents that they will not be penalised immediately if more time is needed for installation. It’s essential for homeowners to be familiar with the requirements to ensure their property is compliant and insurance policies remain valid.

While Wi-Fi connected smoke alarms are not specifically required, they can offer additional benefits such as remote monitoring and control. This can provide extra peace of mind for homeowners and help keep their property safe.

In conclusion, the new smoke alarm regulations in Scotland aim to enhance safety and protection for all residents across the country. By installing the required alarms and adhering to the regulations, homeowners can contribute to a safer living environment and potentially save lives in case of a fire emergency.
