Where do alarms need to be?
Rules vary by nation, but generally a smoke alarm on each storey used as living accommodation and a CO alarm in rooms with a fixed combustion appliance.
How often should I test them?
There is no single fixed statutory interval, so most landlords check at each new tenancy and track it annually.
Legal basis: England 2015/2022 regs; WSI 2022/6 regs 4-5; gov.scot tolerable standard; NISR 2024/123
