What Our Customers Are Saying

Trusted by families, landlords, and homeowners nationwide.

Full Coverage & Total Peace of Mind

We went for the full interlinked set – smoke alarm upstairs, heat alarm in the kitchen, and the carbon monoxide one by the boiler. So glad we did. They all talk to each other, so if one goes off, the others do too – which is exactly what we needed with the kids in different rooms. Easy setup, and gives us real peace of mind.

Claire M. – Leeds

Reliable and Simple to Set Up

Fitted three AlertX interlinked alarms across the house. Setup was straightforward and they synced without any fuss. The carbon monoxide alarm is a big bonus – something I’d put off for too long. My only gripe is I wish the mounting screws were a touch sturdier, but otherwise, very happy.

David H. – Birmingham

Smart Safety for Every Room

Really impressed with the AlertX interlinked alarms. Bought the full bundle for our new place – smoke in the lounge, heat in the kitchen, CO near the fireplace. Tested them and they all go off together like clockwork. Great value and a must-have for any home.

Priya K. – London

Easy Install, Maximum Protection

We wanted proper protection after renovating our bungalow. The interlinked system from AlertX is brilliant – no more worrying if you’d hear the alarm from the other end of the house. All three (smoke, heat, and CO) work perfectly and installation was a doddle. Highly recommend.

Tom & Ellie R. – Southampton

Quick Setup & Great Build Quality

I’m not very handy but even I managed to get the AlertX alarms installed in under half an hour. They feel really sturdy, and the interlinked function is brilliant – I tested it and they all triggered instantly. Feel much safer now, especially with the carbon monoxide alarm near the boiler.

Emily S. – Oxford

Works Exactly As Described

Bought the bundle of smoke, heat, and CO alarms for our 3-bed house. Everything arrived quickly and was well packaged. The heat alarm is perfect in the kitchen – no more false alarms when I’m cooking. Would happily buy again if we move.

Jack W. – Newcastle

Top Marks for Safety & Peace of Mind

We’ve got young kids and an open-plan home, so having all alarms interlinked was a must. The AlertX system is easy to install, looks tidy, and just works. I love that if the smoke alarm in the hallway goes off, we’ll hear it in the bedroom too. Highly recommend for families.

Louise T. – Brighton

Brilliant for First-Time Buyers

We’ve just moved into our first home and wanted to get proper alarms sorted. The AlertX interlinked bundle was perfect – smoke in the hallway, heat in the kitchen, and carbon monoxide in the utility room. Everything was easy to install and the alarms are loud but not annoying. Exactly what we needed!
