Smoke Alarm Installation Cost

How much does it cost to install smoke alarms?

The Smoke and Carbon Monoxide Alarm (Amendment) Regulations 2022 came into force on 1 October 2022. From that date, all relevant landlords must:

1. Ensure at least one smoke alarm is equipped on each storey of their homes where there is a room used as living accommodation. This has been a legal requirement in the private rented sector since 2015.

2. Ensure a carbon monoxide alarm is equipped in any room used as living accommodation which contains a fixed combustion appliance (excluding gas cookers).

3. Ensure smoke alarms and carbon monoxide alarms are repaired or replaced once informed and found that they are faulty.

The requirements are enforced by local authorities who can impose a fine of up to £5,000 where a landlord fails to comply with a remedial notice.

Smoke and carbon monoxide alarms can be hard wired mains powered or battery powered, if battery powered it is advised the battery is a ‘sealed for life’ type rather than replaceable.

A typical mains powered installation will cost in the region of £150 – £300 + VAT, although number of detectors and location will affect this range. It’s always best to get multiple quotes for this type of work.
