Work was put off for several weeks due to family illness. Paul kept in touch and was happy to do the work at short notice on a Sunday. Was pleased with his workmanship neatness and time taken. Paul agreed to come back and install an outside power point which unfortunately he has not done.
I also asked for certified documentation or at least an invoice which has not been received.
Having paid in full I have no leverage and am putting this down as a lesson learned.
