Over to Steve....................
I was looking into getting one of the Liber-T French tolls tags.
I found that no company would provide a unit without having a Direct Debit facility set up from a French bank account now, which we and I guess most families don't have. However, Sanef now have a UK operation that just provide these units for UK customers and they take payment in Sterling by Direct Debit from your UK bank account.
If you are driving just once a year, apart from the convenience factor it may not be cost effective, but if you are driving a few times or maybe work with close friends it's a great piece of kit.
We normally drive through France to Spain over night, so not having to wake the passenger up to get a toll ticket or pay a toll is absolutely brilliant and what's more you can see exactly what your toll costs were, no lost tickets, etc.
Toll charges are exactly the same as they would be if you paid by cash or credit card, but are converted to Sterling using Sanef's monthly conversion rate, which is about as good as you would get from one of the best foreign exchange outlets.
In addition to the annual management fee of 10 euros there is a monthly fee of 5 euros for each month you use the unit, but only up to a maximum of 10 euros a year, the fee starts the month you purchase the tag so if you drive two or more times a year it's great for missing the queues and stops the driver having to wake a passenger to pay a toll, all in all a worthwhile investment.
This is a copy of my invoiced toll charges for the trip we made in August;
You can see the total toll charges for the Rouen - Bordeaux route is 72.70 euros while the Spanish tolls are about 12-15 euros where as I'm sure we paid well over 100-110 euros when we drove via Paris and down to Barcelona.
