I recently had an Intruder alarm system and a CCTV System installed by MJ Security Systems and from the initial discussion with Jimmy to the complete conclusion nothing was to much effort. The engineers did a great job and we are very happy with the end result, thank you and well done for your professionalism during our installation. I wouldnt hesitate to recommend this company.

I wish there was an option for zero star! MJ Security is very lucky that I have given them 1 star. Michelle, the owner, needs to take care of clients or we all disappear very soon. The company is fantastic sending bills within minutes but dealing with cases.... and YEOMAN ARC are one of the worst people I have ever dealt with. They don't respond after normal working hours. I think they have one or two employees picking calls on random basis. I did ask Michelle to change the ARC and use a better one, but as she is the big boss, she has decided not to!. I will update this review with the full story

My new build property had an alarm fitted from this company. I had the alarm serviced every year but because of pets, it was rarely used. When I went away the alarm kept going off and I had put this down to the possibility of spiders on the sensors. The observations of my neighbours led me to believe this was not the case but due to the delivery of post. The sensitivity of the alarm had not been picked up at service and I was reluctant to pay a call out charge for what I believed to be an installation issue. I do not believe the alarm is fit for purpose. The communication over my complaint was
