I live in an apartment with really high ceilings and had put off getting a sparky in for a long time because it was impossible for me to check the bulbs. By the time I got around to ringing Andy, I had a few random lights out and a sparking powerpoint in my guest room. I was running an extension cord from the living room into the guest room to give guests power! In an hour, Andy had replaced the offending bulbs and fixed the power point. I didnt even know that I had the wrong bulb in my bedroom light and now my dimmer works again! Very good service and he did a great job explaining everything to me as well.
