Service Charges And Monthly Energy Consumption

Burglar alarms need regular service to work properly. On average, service is required every three months to test if everything is working properly. For every service, you are expected to pay £80 to £100.


Service charges also differ depending on the type of alarm, number of sensors, and checking wiring. Conducting regular service may seem expensive, but it will save you more bucks in the long run.

When it comes to energy consumption, home monitoring units and CCTV systems only consume 8 to 10 watts, contributing a few cents in energy bills.

Three Cost-Deciding Factors For Burglar Alarms

As mentioned earlier, there is no fixed cost. Both high-end and affordable alarms are available, and one can buy them depending on their budget. Still, factors determine the actual final cost. Let me explain all to you.

1. The Type Of Burglar Alarm

Wireless alarms with keypads are expensive compared to simple wired ring-only alarms. Similarly, the CCTV unit and smart units come with high price tags. Standard home security systems are cheaper compared to commercially used alarms.

2. Burglar Alarms Fitting Cost Also Matters

Proper installation can take up to 2 days. If you’re hiring a professional who charges by hours, then you may end up paying over £350 for the installation fee only. In the same way, the experience of an electrician matters too. 

Most importantly, fitting a wireless burglar alarm is relatively easy as compared to a wired one. But, the service charges for wireless are higher. So, in both cases, the price bracket can sum up to £500 to £600.

3. Your Location

Yes, that matters too! Based on our research, hiring a professional in the city centre is more expensive than in small towns. On average, you’re expected to pay 20% more in major cities.
