    Common Questions

    Frequently Asked Questions about Burglar Alarm Installation

    We understand that you may have questions about burglar alarm installation and how it can benefit you. Here are some of the most common questions we receive, along with detailed answers to help you make an informed decision.

    How much does it cost to install a burglar alarm?

    The cost of installing a burglar alarm system can vary depending on several factors, including the type of system, the size of the property, and any additional features you may need. On average, installation costs range from £300 to £1,500. Contact us for a customised quote based on your specific requirements.

    How do you install a burglar alarm?

    Installing a burglar alarm involves several steps:

    • Assessment: Evaluating the property to determine the best locations for sensors and alarms.
    • Mounting: Installing the sensors, control panel, and alarm devices securely.
    • Wiring: Connecting the components to the electrical system or setting up wireless connections.
    • Programming: Configuring the system to ensure all components work together seamlessly.
    • Testing: Conducting thorough tests to verify the system’s functionality and effectiveness. For optimal results, it’s best to hire professional installers who are experienced in setting up burglar alarm systems.

    How much does a burglar alarm system cost?

    The cost of a burglar alarm system depends on the type of system and the features you choose. Basic systems may start around £200, while more advanced systems with additional features such as remote monitoring, motion detection, and video surveillance can cost upwards of £1,000. We offer a range of options to fit different budgets and security needs.

    How does a burglar alarm work?

    A burglar alarm system works by detecting unauthorised entry into a property through various sensors placed on doors, windows, and other entry points. When a sensor is triggered, it sends a signal to the control panel, which activates the alarm. The alarm can sound loudly to alert occupants and deter intruders, and it can also notify the property owner or a monitoring service for further action.

    How do you reset a burglar alarm after a power cut?

    To reset a burglar alarm after a power cut, follow these steps:

    • Check the Power Supply: Ensure that power has been restored to the property.
    • Locate the Control Panel: Access the alarm system’s control panel.
    • Enter the Security Code: Use your security code to reset the alarm system.
    • Follow Manufacturer Instructions: Refer to the alarm system’s manual for specific reset procedures. If you encounter any issues, our team can provide assistance to ensure your alarm system is functioning correctly.

      When requesting a quote, I received a speedy reply from these guys and an initial visit was arranged shortly afterwards, then upon agreeing on the details and the price, they could offer a brilliant timeline for completion. The job was conducted much more quickly than promised and I am very happy with the result. The electricians working in my home were very nice and friendly and they made sure that everything they did was to my satisfaction.

      Based on other positive reviews I contacted Klisi to do some urgent and much needed repairs. He made his inspection and provided the quote that same evening. He and his colleague worked well as a team. They were friendly efficient and did the job professionally and with care and kept us informed when necessary. They left the premises clean and tidy. They are an excellent choice and offer a high quality seŕvice. I was so impressed that I look forward to welcoming them back to undertake some additional work. Thank you both!

      I cannot praise Klisi enough for the splendid electrical work he and his brother completed at our house. They were very competent and kept me well informed throughout the work. I was also super impressed with how tidy and clean they worked. I wouldn't hesitate to have them back to look at any other electrical jobs in our house in future. Thank you.

      Klisi responded promptly over the phone and came to do a little survey at first. He gave an immediate quote and after few days he came to do the job. He had to come a second time, didn’t charge nothing for second visit and completed the job to an high standard with professionalism and courtesy.

      We did quite a lot of work with Klisi and his team as we moved to a new home, and they were amazing. They checked our electric board and repaired it, added news plug sockets in our Victorian house, and a few more things. The team was very professional, quick, accommodating and lovely. Definitely calling them back next time we need anything done.

      This is the first time I have used Contact Electrician Ltd. Klisi was prompt in replying & very responsive in communications. He was able to get an electrician out to me in 48 hours & that Electrician (Eli) was polite, professional, & very capable. I am very pleased with the work.

      Had a couple of jobs done and I’m extremely happy. The guy went out of his way to find the parts, kept me updated all the way, arrived on time, was polite and very efficient. He even sourced the bulbs for the light fixture, one of the jobs he was doing. A very fair price. One very happy customer. Shall not hesitate to recommend and use again.

      Klisi is a very supportive electrician who takes the weight off your shoulders when dealing with tenants and gets the job done. Never met the guy but only communicated by WhatsApp and both jobs done without a fuss. He is my go to man as trust and reliability is the most important thing in a tradesperson. Can’t wait to have him do work in my home as well and will be recommending him to friends and family. Thank you Klisi.
      ★★★★★

      Helpful, friendly and professional service. Klisi responded quickly to my messages and was flexible with times owing to my switch & pendant light arriving on separate days. Samuel did a great job with care & consideration of the property. Would highly recommend. Thank you guys.

      Kristian Webb
      Great - experience. I had an unknown electrical fault repeatedly tripping my fuse box. Dani arrived at 8 o clock on the dot, unfortunately the problem wasn’t straight forward so another electrician Johnny attended too. They eventually found the issue and got everything working. The guys were really good - price was extremely fair. Will 100% use them as my electricians from now on. Highly recommended.

      We could not recommend Contact Electricians more highly. Jonny and Denni (forgive me if I've misremembered their names!) worked so hard to do remedial work following an EICR at our property - they replaced our fuse box and were able to come out quickly following booking. They were kind, explained all the changes they'd made and then cleared up the site they were working on so neatly. We will be using this company again!

      Had a very positive experience with Contact Electrican Ltd - Klisi did a great job replacing an old consumer unit with a new metal version and created minimum disruption while I was working from home and left everything tidy after doing the work. A team also came to install a network of smoke and heat alarms in our apartment block and did this efficiently and for a competitive price. Would highly recommend.

      Really happy with the service. I had an issue with my Megaflo and was left without hot water. They came out quickly, properly investigated the electrical issue and explained clearly what needed to be done. The repair was completed promptly and for a reasonable price. Very professional and helpful — I would definitely recommend.

      I cannot recommend Klisi and Contact Electrician enough. After having truly disastrous experience with a precious electrician, he stepped in and turned the situation around completely. He responded to my inquiry remarkably fast and handled the job with the utmost professionalism. A clear thorough detailed EICR report was quickly provided. Absolute lifesavers-fair and honest
