What factors affect the cost of burglar alarm installation?

Type of burglar alarms

Before diving into the costs of burglar alarms in the UK, let’s first discuss the different types you can buy in the market today. There are five main types of burglar alarms: bells-only burglar alarms, dialler/monitored burglar alarms, smart burglar alarms, wired burglar alarms, and wireless burglar alarms.

  • Bells-only burglar alarms are the standard kind and the most popular in the UK. These alarms use sensors to detect possible break-ins and then trigger a very loud sound or siren to alert nearby people of intruders. However, since they’re not monitored, they rely on homeowners and neighbours to respond or call the authorities as soon as the alarm is set off. If you live in secluded areas, this may not be the best option for you.
  • Dialler/monitored burglar alarms work like bells-only alarms, but betterThese alarms can contact someone once the alarm is triggered. It could be you or a family member you’d like to notify in case of an intrusion. You can also opt to avail 24/7 burglar alarm monitoring services, one that can also contact the police if needed.
  • Smart burglar alarms are paired with smartphones. It sends an alert via notifications and an app on your phone. It can also be integrated with other smart devices such as CCTV and lights. For example, when a burglar alarm is triggered, the smart lights would suddenly turn on to deter the intruder. You can also switch the alarm on and off from your phone. 
  • Wired burglar alarms have wires that connect to sensors. It can take longer to install and may require professional service as the cables and wires should be set up properly. Because of this, expect to pay higher installation fees or labour costs. However, they’re cheaper to maintain since you won’t worry about battery life.
  • Wireless burglar alarms use Wi-Fi or radio frequency to connect to sensors. Since it doesn’t have wires, it’s easier to install. But the downside is the maintenance cost because you may need to replace the battery every couple of years. Besides this, you may also consider or check the areas you have at home that have interference for wireless devices to work.

Number of sensors

Burglar alarm systems measure unexpected or unwanted changes in the areas where they are installed. The most common type of detector is PIRs or Passive Infrared Detectors, which measure the temperature within the room. If deviation heavily occurs, such as when it detects the body heat of a burglar, it will trigger the alarm.

Any simple alarm can be easily installed. However, for a monitored system, you may need to hire a professional to hardwire the alarm panel into your wiring system. Aside from the danger of doing it yourself, you can ensure that the alarm will be much more dependable if installed and checked by a trade professional.
Yes, they can. So if you have pets, you may talk about solutions with your installer. If you live with a small pet, such as a cat or a small dog, who doesn’t jump on furniture or tabletops, you can ask the installer to include PIRs on the system. PIRs don’t monitor body heat right to the ground, so they won’t be able to detect your pet’s daily activities as a threat. But if you live with pets who like climbing, or if you own big dogs like a Malamute or a Retriever, you may talk to your installer about using a window and door sensor instead.
The burglar alarm system is an investment for your safety and peace of mind. To ensure that your tradesperson properly handles your investment, you can ask about their experience and how quickly they can fix the system once problems arise.
