Can anyone throw any light on whether or not this might be the case.

Sounds like a sales tactic to me. If you were indeed on prepayment tariff when you switch then utilita should of changed meters into credit mode before you left. If you are still in the switching process then they need to do this now without fail or excuse.
If the switch has completed then once the credit runs out the lights will go out. So it all depends how long ago you switched.if last couple of days and your meter shows your running out of top up then PP need to sort this for you.if its been a couple of weeks then its waffle from utilita.
