Who can replace mains powered smoke alarms?

[Guest HayleyB]

Hi,
I own a licensed HMO and our fire and heat detectors are coming up to 10 years since installation and will need replacing.

I am aware that hard wired detectors need to be installed by a competent person, but is this necessary to replace the units? The replacements would just be a like for like switch over which would use the same wiring circuits that currently exist.

The units are regularly tested as per regulations.

Kind regards,

Hayley

What category of fire alarm is installed, are they individual smoke and heat detectors or is it a full system with a control panel. If it is a category D system with individual detectors then it is just a case of disconnecting the detector from its mounting ring and replace with the new detector. If it is a category A to C with a control panel, then you will need the services of a fire alarm company.
