Is it any different renewing my mexican passport even though it has expired?

Is renewing an expired UK passport the same as renewing a current one?

• My UK passport expires this month. I have no plans to travel to Europe anytime soon. Maybe it will be years until my next trip. Is it harder to renew an expired passport than a current one? For example, if I wait a few years before renewing, will I have to submit more documentation or pay a higher fee than if I renew now, before this one is expired?

• Answer:

  The renewal procedures and fees are the same regardless whether you apply for the renewal of a current or of an expired passport. You might need to get your application countersigned and have your photograph certified if your appearance has changed that much that your identity cannot be checked based on the previous picture in your passport and the current picture you provide for the application of a new passport. http://www.direct.gov.uk/en/TravelAndTransport/Passports/Renewingorextendingyourpassport/DG_174096 .. I remember to have read somewhere that only applicants which hold an old blue passport (issued before 1988/1989) need to apply under the first time application procedures to include a citizenship interview.
