An estimate of the cost to landlords of fitting smoke alarms in their properties has not been made. The English Housing Survey shows that 92% of homes in the social rented sector and 82% of privately rented properties have a smoke alarm. The cost of a smoke alarm ranges from about £5 for the most basic model to more than £25 for a hard-wired device. We recently published a discussion document on how we can improve property conditions in the private rented sector. Among other things, it invites views on whether landlords should be required to install smoke alarms in their properties.
