Adrian was fantastically helpful when I found myself at 11.30 on a Saturday night with my smoke alarm going off and not knowing what to do. I phoned him in a panic to ask for help. Adrian got me to take a picture of the alarm so that he could identify the model and then he proceeded to guide me through disconnecting it. He saved me £75 call out charge and with his help I was able to fix the problem in less than 30 minutes and then to get a good night sleep. A big thank you!
