Timetable for passport applications
The Identity and Passport Service (IPS) recommends that you allow six weeks for a first adult passport. There's a range of options for other passport applications, depending on how soon you need to travel. The best advice is to apply early whenever you can.
Allow more time for first adult passports
If you're applying for your first adult passport, you'll need to allow more time than in the past. This is because in most cases you'll need to attend an interview. See ?Passport interviews? for more information.
IPS recommends you submit your application six weeks before you need to travel. Don't book any travel arrangements until you have received your new passport.

When to renew your passport
When renewing a passport, you don't have to wait until your passport runs out. You can apply at any time. IPS will add any time left on your old passport to your new passport in whole months - up to nine months. IPS can't carry over more than nine months from your old passport to your new one.
You can renew your passport whenever you wish, but you must pay the full fee. No refund can be given for any unexpired time left in your old passport.
Timetable for applying
These times don't apply to first adult passports. You should allow six weeks for first adult passport applications as you'll usually need to attend an interview.

By post - three weeks
IPS aims to return postal applications within three weeks of receiving them. This is provided you have filled in your form properly and sent the correct supporting documents.
If you don't do this, IPS may not be able to issue you a passport in the expected time. For this reason, IPS strongly advises you not to book any travel until you have your new passport.
Online applications - three weeks
The three-week guideline also applies to application forms submitted online.
IPS prints out your completed form and sends the paper copy to you to sign. As with postal applications, IPS doesn't officially receive the application until you have signed the paper form and sent it back with supporting documents.
Post Office Check & Send service - two weeks
The Post Office Check & Send service is available through certain Post Office branches. Your application should take two weeks from the time the branch or agent accepts the application, not including bank and public holidays.
This is not a guaranteed service and may take longer during busy times. IPS advises you not to book any travel until you have your new passport.
The service is explained in detail in ?The Post Office Check & Send service?.
