When applying for insurance or in the event of a claim following a burglary, your insurer may ask for proof that an alarm has been installed in line with their requirements. If your alarm is installed by a NSI approved company, you will be issued with a Certificate of Compliance which should be presented to the insurer as required.

You may be entitled to receive a discount if your intruder alarm meets your insurer’s requirements, check with your insurance company before you apply for or renew a policy to avoid losing out. If you are using an insurance broker to arrange your insurance, make sure they check this for you.

Our Alarms

Protecting hundreds of homes across the Lincolnshire & Cambridgeshire region with Intruder alarms installed, monitored and maintained by SJG Electrical & Security, we guarantee to work to the highest industry standards.

As a National Security Inspectorate our security systems meet all requirements demanded by the Emergency Services and the Insurance Industry.

Bells Only Alarm

A bells-only alarm is an alarm which makes a noise when a break-in is detected. The external alarm will only continue for a maximum of up-to 20 minutes. But the internal alarm and outdoor light will continue to flash until the system is turned off. Unmonitored systems are typically used at lower-risk homes, those without a significant amount of contents or valuables.

Smart Alarm

Access and control your home from anywhere in the world through your smart device via the HKC SecureComm Cloud. Enjoy the security benefits of the multi-award winning Hybrid alarm system, with on board 2 way wireless receiver.

Monitored Alarm

Peace of mind comes not only from having a fully integrated home security system, but also from having highly trained staff monitoring your security twenty four hours a day. Most insurance companies insist that alarm systems are monitored to provide emergency response in the event of an incident. Our 24 hour alarm response centre is connected directly to all UK emergency service. We will make sure that the Police, Fire Brigade or your Keyholder is called out to your home whenever they’re needed.
