Received an automated message the evening prior to the appointment advising that the installation was going to be cancelled. Had to phone the utility provider (Usio) to double check if it was going ahead. Luckily, Usio are quick at answering the phone. Had it been one of the big 6, I suspect getting hold of someone may have been very time consuming. Engineer arrived just before the end of the allocated time slot, but without having phoned half an hour prior to arriving as had been promised. The installation itself was quick and the engineer was polite & professional.
