Dear Sir/Madam

I was looking at hiring one of your vans for 8 days at the end of October. In particular I was looking at 11 Passenger Van E350 Ford E-350.
I was wondering what kind of driving license I need.
I am 30 years old with a European driving licens obtained when I was 19 (and I converted the European driving license into a Full UK one about 2 years ago as I moved to the UK).
Am I allowed with this driving license to drive the Van?
Reading from the back of it, I can drive AM, A, B1
