The Home Office is planning to increase passport fees this year, with postal costing more than online applications.
Currently, a standard adult passport or renewal costs £72.50 regardless of how the application is made.
The fee will rise to £75.50 for online applications and £85 for postal applications.
Charges for children’s passports will go up from £46 currently to £49 online and £58.50 in the post.
The changes are underpinned by new fee-setting powers given to HM Passport Office under the Immigration Act 2016 to give it the resources it needs to process six million applications a year.
The changes have been earmarked to come into effect in just a few weeks.
If they are signed off by Parliament, they will come into force on March 27.
