"First job with Scott. He was the only one of 3 electricians we contacted to offer a visit to survey a small job in person (garden plug sockets). That personal touch is exactly what we wanted. Prompt, polite, tidy, can’t ask for more really, and the job was done in the time quoted. There’s more to do in our new home and we will definitely be asking for Scott’s help again in the future."
