Report
I was extremely grateful to Adam, Christine and the team. I was getting my flat refurbished and the rewiring was an essential part of that. I had contracted another electrician, whom I won't name because I did get my money back from him, and he repeatedly simply didn't turn up. Obviously I was out my flat and the delay was costing me and my builder. I phoned Adam and the very same day he sent someone round for a quote and his team started on the job the next day.
The job was done quickly even although at one point the lead guy was dealing with family illness - Adam just stepped in and ensured someone else was there. I am really pleased with the end result and above all with the friendly efficient service. I am in no doubt they saved me thousands.
