Alan came to my parents’ house at Greenwood to replace the security light. He is a trustworthy, tidy and reliable person hence for the last few years, he is the electrician I always called. I told him that my parents wanted to save electricity etc, hence he adjusted the sensor to meet their needs. He also kindly loosen the screw on another external lamp so that I could change the bulb later. In the end he also tested the RCD switches that he installed years ago and provided an official ELECTRICAL SAFETY CERTIFICATE for them.
