Every home in Scotland must have interlinked fire alarms by February 2022. Interlinked means if one goes off, they all go off, so you will always hear an alarm wherever you are in your home. It is the property owner’s responsibility for meeting the new standard. For more information see https://www.gov.scot/…/fire-and-smoke-alarms-in…/.
If you have a Care and Repair Service in your area you may be able to get support from them.
