New legislation on smoke alarms and carbon monoxide detectors from 1 October 2015. A smoke alarm is now required to be installed on each floor of a rented property and must be tested and confirmed as operational at the beginning of each new tenancy. During the tenancy it becomes the tenant’s responsibility to check the smoke alarm is still working. It is advisable to test the alarm on a monthly basis as a minimum. Carbon monoxide detectors are now compulsory for properties with smokeless fuel or coal fires. It is advisable to install carbon monoxide detectors in properties with gas boilers as a safety precaution, although this is not as yet a legal requirement.
