This depends on the layout of your home. The sooner a smoke alarm detects smoke, the quicker it’ll warn you of the danger. This means the more smoke alarms you have, the better you’ll be protected from fires.

It’s recommended that there be at least one smoke alarm on each floor of your home. But for larger properties, you may need more than this.

Luckily, smoke alarms need very little in terms of maintenance. Apart from occasionally using your vacuum brush attachment to remove any dust, your alarm should keep functioning properly.

However, regularly testing your smoke alarm is a must. We’d recommend testing your smoke alarm every six months and changing the batteries annually.

Installing smoke detectors can save your home and your life, so they’re well worth the investment.

Wondering how much it costs to install smoke detectors in the UK? Well, firstly, consider the below factors:

• The type of alarm - There are a range of different smoke alarm systems available, each with a different price tag.

• The size of your home - If your home is on the larger size, you’ll need more smoke detectors and possibly a more complex smoke alarm system.

• Installation - Depending on how complex the installation process is, the price you pay will vary.

• The number of alarms - The more smoke alarms you choose to have installed, the more you’ll pay.

• Accessibility - Difficult to access areas in your home mean longer labour times and higher labour costs.

There are a few reasons your smoke alarm keeps beeping and depending on the type of noise it’s making, you should be able to figure out the issue.

If your smoke alarm is bothering you, consider the following potential problems:

• Loud and constant beeping - Your alarm may be detecting smoke but if there’s no fire, it could be triggered by steam, humidity, an electrical issue or even a build up of dirt in the sensor.

• Continuous chirping - Usually this means the alarm’s batteries need to be changed as soon as possible.

• Random chirping - This is often an indicator that your batteries are running low but it could also mean your alarm has a loose wire.
