HUNDREDS of thousands of Brits are making a common passport mistake - leaving them out of pocket.
Passport fees are set to rise this month, with the standard fee rising from £82.50 to £88.50.
However, this is only for people applying online.
A recent investigation found that as many as 850,000 people applied for a passport via a paper application last year.
This is set to rise to £100 from £93 - costing more than £10 extra if applying via paper rather than online.

"In order to travel to the EU, all passports must be no more than 10 years old on the day you arrive in your European destination.
"And you'll need at least three months on your passport on the day you head back to the UK."
