I 've made no booking nor have I shared any information about myself with the company. The conditions to which I'm referring are given on a pop-up screen there on the page which details the offer. So it's "nothing personal". I need a car for four days and this company appeared organised and well-presented and is about £20 cheaper than others.
In part I was asking the question in order to try to find out if these sort of restrictive conditions are becoming or tending to become "the usual thing".


"the German authorities got it wrong and gave me more stuff to drive than I'd had on my old licence."
German's making a mistake...........Never!!

For info I have used Argus as an agent many times over the last five years or so usually to pick up in Belfast and have never had any problem. As noted they are an agency and in my instance over the years the car hire company has been Budget, Hertz and more recently Sixt. No-one has ever asked me for a utility bill. Since I will have flown in I will have my driving licence and passport.

The plot thickens. Several days after asking Argus for clarification, I received the following reply:
"*Please be kindly advised that the above refers to renters with a UK driving license. As I understand, this one would have to be presented, as you are a holder of a UK passport. This does not yet mean, however, that you will not be able to drive a rental car. Please note that some rental providers can make expections, however, it is necessary to proceed with the booking first and enquire them in regards to an existing rental. Should they disagree, your reservation can be cancelled free of charge within 48 hours of the confirmation date."
The country that issues the passport and the country that issues the licence should be the same, they are saying, but "some" renters "can" make exceptions. Just book first (pay your money) then ask the renters if your licence/your passport will be OK. Hope that you get an answer within 48 hours, hope that if the answer is negative, cancellation is then not problematic, and hope (if the answer is "OK") that the person who gave this answer "OK" and the person at the pick-up desk interpret the regulation in the same way. What could be simpler?
Anyone reading this with experience of having a passport and a driving licence from different countries?

Yes, my youngest daughter who has dual nationality, has two passports, one UK and one Australian, passed her driving test in Oz and only has an Australian licence but was able to hire a car here. So, she's British but drove on her Oz licence, but I suppose she could have shown her Oz passport too, if needed. She has no permanent address in the UK as she lives in Oz, and definitely wouldn't have had a utility bill with her when here on holiday.
She rented through Thrifty - going directly to them and not bothering with an agent. Might be worth giving them a call?
