I got a fine from a rental in the UK. Should I be worried. What next to do

Is your CC maxed out? My understanding is that they keep your details for months after the rental period specifically to deal with fines and tolls etc. And yeah the admin fee is extra salt getting rubbed in.

What next to do?

Pay the fine.

Would you not just pay it then?

Someone has to contact you and organise payment of the fine - not a bad price for the couple of hours work it will probably take to sort kindly on your behalf.

Surprised they accepted Revolut excactly for this reason. Rented a car in the UK 2 weeks ago and it was strictly credit card only.

where do you see a couple of hours work?

How much would you value someone’s time for sitting down and paying your fine on your behalf?

+ Tax

+ Pension

+ PRSI

it’s a bargain really.

It's more if it was a speeding fine where you could have an outstanding case in the UK that might cause an issue travelling through UK in the future. If the UK government flagged you as failing to turn up to court, unpaid fines etc then you could be stopped at the border or arrested during a routine UK traffic stop.

In terms of admin fees these are common and routinely excessively high. They add them to things like toll/m50 fees. Part of the reason they are high is because people like yourself try to not pay them, so car company may be liable. I suspect they will try claim the fee again at a future date. There have been cases where (mostly foreign small dodgy) hire companies throw a fine on your card months later for a toll or speeding fine that may not even be real and once transaction has gone through it's hard to verify and dispute.

Personally I would ring them and pay it. Not worth potential future hassle. If you did the crime.

Shudda got your accountant to pay it for you in the first place so, or maybe got your accountant to drive you around and find legal parking spaces for you.

I've used debit cards before. Some companies charge extra for it, some don't. Some won't accept them.
