Smoke alarms now have to have battery lasting at least 8 years! New installations

[Nick G]

Yours in inspections and between tenancies. Part of your insurance is to have working smoke alarms. Well you could put your insurance in the hands of your tenants...

I would give you one go at deciding that - and it wouldn't be the tenant.

I installed hardwired smoke alarms before 10yr/hardwired was mandatory. They are connected together so if one goes off, they all go off. Tenants will get out alive!
