I cannot recommend Sam and his team highly enough. Great communication during every step of the process and arrived for work at the time promised. There were a couple of impossible to see, prior to the work, difficulties which delayed the job ever so slightly but Sam came on a Sunday to complete the work. The installation was neat and tidy, as was the entire work area during the time they were here. Based on my experience with Cornwall Electrical Systems they are the best company to do the job, a rare thing for me to say nowadays.
