They could - and, IF the explanation of the 'verification process' I've read is correct, then they would get away with it unless they 'fudged' the numbers to a ridiculous extent. In particular, if the new supplier was going to be the cheaper, then they could 'fudge' the changeover day reading right down to just fractionally above the previous reading and, per the process I have read, inevitably 'get away with it'.The customer him/herself could fudge the readings, to squeeze a little more from the cheaper supplier.
Am I the only person who thinks that is just plain ridiculous (and a waste of what will eventually be customers' money)? Why on earth should they even ask for, let alone 'trust', a customer's 'manual' reading if they have the ability to determine the actual reading themselves without having to step out of their office?!!Yes, even with smart meters, they ask the customer to supply a manual reading and it goes through verification process. I have gone through the process three times now, with a fully functioning smart meter. They have never disputed the manual readings I have provided.
