Being inundated with firms wanting me to use them was not helpful. And lots of emails. A simple list of available electricians and a little introduction is all I needed. The fact that I was phoned, unsolicited, was very intrusive. Thsi was by a company with 'global' in the title - well I was immediately doubtful about them. I spoke to an electrician Richard who was fine, but passed me through to a booking office - when I was told I needed to pay a about £78 deposit, made me realise this is not for me, and so I declined. I did chose the most human sounding individual, based on his introduction and he was fine, booked me in and demanded no deposit. So a simpler system, less intrusive would help; and more personal, optional (not cold call) contact was the more successful one!
