Private sector landlords in England are required, as of 1 October 2015, to have at least one smoke alarm installed on every storey of their properties and a carbon monoxide alarm in any room containing a solid fuel burning appliance. After that, the landlord must make sure the alarms are in working order at the start of each new tenancy.

The requirements do not give details regarding the type of smoke alarm. However, my understanding is that since the 1990s the approved documents that give details of how to comply with the building regulations have specified mains powered alarm systems, unfortunately I do not have access the previous approved documents.

The current Approved document B specifies minimum Grade D2 Category LD3 standard, in accordance with the relevant recommendations of BS 5839-6. I would recommend that you consider that as the minimum standard for any rental property.
