Charlie, agreed a price and was scheduled for Wednesday. He called on the day and rescheduled for Friday, due to feeling unwell. He then called on Thursday and we agreed for him to attend at 1pm. He cam then began renegotiating, which was a surprise as he had all information before arriving. He then agreed to honour agreed price and rescheduled for Tuesday. He never arrived, called or answered my call. I would not recommend Charlie or this company.

Came very quickly and completed the job (like-for-like electric shower replacement) satisfactorily, my only gripe is the price/cost. Said it would be about £250 - £350 at the start, on completion of the job the price had gone up to £480 and he wanted it in cash. Not much I could do when the job's finished and the guy's standing in the house wanting to be paid. On reflection I feel I have been overcharged and should have waited for the other responses to come in but needed it doing.
