I needed a door contact re attaching, so I phoned Nova on the Friday afternoon, and they came out on the Monday and sorted everything out perfectly.Couldn't ask for a better and speedier service.Proper friendly too, everyone I spoke with. And they saved me a lot of money rather than going through the company who originally installed it, who wanted more than twice the price just to come out.Would definitely use again!

Had an alarm system with nova now for about 10 years. I have just moved and they was my first choice again. The product, support and customer service is second to none. The support and customer service largely down to a fantastic lady called Charlotte who is always willing to go that extra mile. She is always friendly and helpful with no problem to big or to small. The companies great and she's an asset to them
