My experience in the past with a fuel card wasn’t what I expected. I thought it was just like an interest free credit card and I get the bill quarterly and pay it off.
I knew there was a yearly payment of £60 or something like that to have the benefit of using this fuel card but what I didn’t realise until about the 3rd payment was that the fuel card company adds a few pence more on to every litre you fill up. As it was quarterly billed , I didn’t realise , as I had filled up quite a few times in 3 months so never noticed the extra they were adding on my bill every time I filled up.
The last quarterly bill I sat down and added up how much I had filled up and then noticed my bill being higher than what I actually used.
I cancelled straight away as it just wasn’t worth it and now just use my normal business account card. I’m not sure how other fuel cards work but this was called (I think) fuel genie.
