Smoke Alarms

Smoke alarms are one of the most important items in your house but it often gets neglected. Discover why your smoke alarm is important and the best ones on the market right now to suit all homes and budgets.

Smoke detectors or smoke alarms often are not really thought about in the home or seen as a nuisance when they go off every time you burn your toast resulting in you taking out the batteries to save your ears. But just sit back and really think for a minute about just how vital they really are, especially when using your appliances more frequently.

Fire statistics in the UK

Did you know that over 600,000 house fires occur in the UK every year? Around 800 of these cases result in death and over 17,000 injuries. If you do not have a working smoke detector in your home you are more than twice as likely to die in a house fire compared to a home that does, your entire home can be engulfed by flames in less than 4 minutes. It isn’t just the flames you have to worry about as smoke is the biggest killer when it comes to the household fires.

These statistics are scary but they are true, take a look at our smoke detector advice below.

What are smoke alarms/smoke detectors?

Smoke alarms are small, self-contained devices that are usually fitted to ceilings within a home or business place. They aim to detect fires and provide families with a few precious minutes to escape from a fire by giving them a warning via a loud beeping sound.

What types of smoke detectors are available?

Fire Service reports that there are four types of smoke alarms on the market, they are:

Ionisation: Cheap and effective. This type of smoke alarm is able to detect small particles of smoke before it gets too thick, these are produced by fast fires from fast burning materials such as paper and wood. They are less effective to slow and smouldering fires which let off a thicker, denser smoke before the flames. They say Ionisation smoke alarms are too sensitive to be placed near kitchens.

Optical: More expensive but more effective to slow burning fires. They are best suited to be fitted near but not inside the kitchen.

Heat Alarms: Detect rising temperature. Heat alarms do not detect smoke so they are best suited in a kitchen.

Combined Alarms: There are two variations of combined alarms.

  • Combined Optical Smoke and Heat Alarms: to reduce false alarms and increase speed of detection.

  • Combined Smoke and Carbon Monoxide Alarms: to detect smoke and abnormal CO emissions. See our guide on Carbon Monoxide Alarms here!


Each of these types of smoke detectors are powered by batteries or mains power or even both and can even be synched together so that they all sound when triggered.


Which smoke alarm do I need?

Fire Service put it really easy for you as to which smoke alarm you need in which room:

Kitchen & Garage: Heat Alarms

Landings: Ionisation or Combined Optical Smoke and Heat Alarms

Bedrooms, living rooms and hallways: Optical or Combined Optical Smoke and Heat Alarms

How many smoke alarms do I need?

You should have a minimum of 1 smoke detector per floor in your home. For maximum protection a smoke alarm can be fitted in every room except bathrooms as steam may trigger the alarm.


Installing smoke detectors

Installing your smoke detector correctly is vital, without doing so it can render the smoke detector useless. If you are unsure how to install your smoke detectors ask for help from friends or family, if that isn’t possible there are many companies or local handy people who are able to install smoke alarms correctly for you at a cost. Fire Service’s top tips are:

  • Install on the ceiling in the centre of the room or as close to the centre as possible.

  • Ensure your smoke detector is at least 30cm away from any walls or light fittings.

  • Ensure your alarm can be heard from anywhere within your home but especially near to the bedroom/s.


Maintaining smoke detectors

To ensure that your smoke detectors remain in good working order there is a little bit of maintenance you will need to do, including:

  • Weekly: Test your alarms once a week by pressing the test button, it will then sound, ensure the sound is loud and clear.

  • Every 6 months: clean your smoke alarm every 6 months by hoovering it using the extender tube. Ensure you go around the edges of the smoke detector and over any small holes in the alarms.

  • Yearly: replace the batteries of all your smoke alarms every year.

  • Every 10 years: it is recommended that you should replace your smoke detectors every 10 years to obtain optimum performance.

Safe and well visit

Did you know that your local fire and rescue service offer a free of charge service where they carry out an inspection of your home to ensure you remain as safe as possible? You may also be eligible for free smoke alarms to be fitted where it is required. To book one in, simply search ‘safe and well visit in (your location) and you will be able to book online. If you cannot access the internet simply give your local fire station a call, you will find the number in the phone book. Do not call 999 for a safe and well visit. This number is to be used only in an emergency.



Could you afford to rebuild and redecorate your home if a fire were to devastate it? Not only are smoke detectors vital as life-saving devices, they are also important factors in your home insurance should you find yourself unfortunately making a claim on a house fire. If your smoke alarms are found to not be working in your insurance application when you had previously stated that they were in good working order, even if the batteries have just ran out of juice then your insurer may not pay out on your claim. Always maintain your fire alarms.
