Smoke and heat detectors are two of the simplest and most effective ways to keep your home safe. But they can only help if they’re working properly. Here’s everything you need to know about checking and maintaining yours. 

What’s the difference between smoke and heat detectors? 

In most homes you’ll find two types of detectors: 

• Smoke detectors – usually in living areas and hallways 
• Heat detectors – typically found in the kitchen 

Both are essential. Smoke detectors sense smoke in the air, while heat detectors respond to sudden increases in temperature – reducing the risk of false alarms when you’re cooking. 
 
Every level of your home should have at least one detector. 

Who installs and who checks? 

If you rent your home from us, we install and maintain your smoke and heat detectors. If you own your home, including shared ownership, you’re responsible for installation and maintenance. 
 
But everyone is responsible for checking that alarms are working. The Kent Fire and Rescue Service recommends testing alarms once a month.

How to test your alarm 

It only takes a minute: 

• Press the test button on the alarm. 
• If it’s hard to reach, use a broom handle. 
• You should hear a loud beep – that means it’s working.

If the alarm doesn’t sound, or if you’re worried it’s faulty, call us on 01892 501480. You can also find help from Kent Fire and Rescue Service. 

What if it starts beeping randomly? 

This usually means the battery is running low. 

• Please replace it as soon as possible – don’t wait until it’s completely flat. 
• Please don’t cover the alarm to silence it – this can stop it working completely. 
• Remember, never remove a battery to use in something else, like a toy or remote control. 

If you rent your home from us, we’ll replace the alarm when needed. 
If you own your home, alarms should be replaced every 10 years, as they can get clogged with dust over time. 

Keep it clean 

Each time you test the alarm, give it a quick clean: 
– Use a vacuum cleaner or a dry cloth to gently remove dust. 
– Avoid using any sprays or polish near the alarm – this can stop it working properly.
