Today I've been misinformed 3 times by Utilita staff that you can stock up on credit and this credit can be spent at the lower rate even after April 1st until that credit runs out (providing you don't top up again until that credit is nearly gone).
The above rule does not apply to smart meters, only legacy meters. Clearly there is a training issue. Just wanted to warn other customers.
Interested to know if anyone else has been misinformed.
Thanks
