UK passport holders are being urged to check the whereabouts of their documents now, particularly if they've got any holidays on the horizon.

Many of us have mislaid our passports at some point, so it's wise to store yours in a specific spot, such as a lockable drawer or cabinet. The Passport Office advises that you must cancel a lost or stolen passport immediately, to minimise the risk of someone else using your passport or stealing your identity. You can also report a lost or stolen passport on behalf of someone else if they're unable to do so themselves.

However, it's crucial to search your home thoroughly for your passport before declaring it lost. This is because once you notify the authorities that it's lost or stolen, you won't be permitted to use it if it turns up and regardless of how much validity it has remaining.

This is because, when you report a passport as lost or stolen, all the information on the document is forwarded to the National Crime Agency. If you try to travel with it, you'll be stopped at the border and it will be seized.

If you do locate your lost passport, you should instead cut off the top right-hand corner and post it to the Passport Office alongside a Recovered British Passport Form. You'll then need to apply for a new passport if you wish to travel abroad.

The current estimated processing time is a maximum of three weeks, though government officials warn it can occasionally take longer "if we need more information, or we need to interview you". If this applies to you, you'll receive notification within the three-week timeframe.

A standard adult passport, for those aged 16 and above, costs £94.50 when you apply online, or £107 if you use the paper application form. However, if you require a replacement passport urgently, a one-week fast track document costs up to £191 for an adult.

A one-day premium service costs up to £235.
