Would recommend!
We inherited an old alarm system when we bought our house over 10 years ago. I contacted Dan to do an initial service and he has been great over the years whenever I've needed him for alarm services / improvements / general help! When we eventually get round to replacing the alarm system I wouldn't hesitate to use Dan again.Verified reviewerJob location: DA1410 Burglar Alarm Servicing
