For the record, it was me, not WheelieBin, who wrote - not for the first time - that I wouldn't touch any of the currently available "SMART" Plans with a bargepole.
And (I would have assumed that this was obvious, but for anyone with comprehension difficulties) that's MY opinion based on lengthy and comprehensive research into the available SMART options. It relates solely to MY consumption of electricty in MY humble (BER A1) home.
I wouldn't dream of arguing that SMART plans may well suit other consumers with different lifestyles and energy requirements.
Incidentally, I've just ordered an even longer bargepole from Amazon.com!
