ah, it’s er complicated… initially there’s no fees unless if you don’t use it which I’ve learnt the hard way. Approx £50 every six months for not using it. Long story, moved house and tried to update the change of address but hit few snags which led me to not using the card, I couldn’t use Esso diesel as my Transit demands the finest diesel from BP or Shell. Low grade diesel caused emission problems with the Transit. This is how I discovered the charges which I wasn’t even aware of applied every six months. Probably mentioned in the small prints somewhere.
