If your passport is lost or stolen you will need to complete the LS01 form to obtain a new one.
So if you are travelling abroad, check your passport at least two months before your trip so you have enough time to replace it if you need to.
UK Passport Service safety advice
Make sure you keep a note of your passport number and a photocopy of the personal details page as this helps the UK Passport Service to issue you with a new one
Keep your passport separate from other important items both at home and when travelling
Reporting a lost or stolen passport
You can report a lost or stolen passport online on the UK Government website.
If you'd rather use the phone, and if your passport is lost/stolen within the UK, call the Passport Adviceline on 0300 222 0000 (lines are open 8.00am to 8.00pm Monday to Friday and 9.00am to 5.30pm weekends and public holidays) immediately to get an LS01 form. Alternatively, you can get the forms you need from police stations, selected Post Office ® branches and Worldchoice travel agents offering the Check & Send application service.
If your passport is lost/stolen overseas, report it to the local police and then contact the nearest British Consulate, Embassy or High Commission. They will be able to help you report the loss to the Identity & Passport Service and provide you with replacement travel documentation.
