“Stephen Wood is a very conscientious, he has been servicing our addressable alarm system since2012, he always turns up every six months without being prompted.

When we have had a fault error message on the fire alarm panel he has come out within an hour to assess and repair the fault, he even came out at short notice on New Year’s Eve as he always makes the safety of customers and staff paramount. I wouldn’t hesitate to recommend him and his services.”
