UK passport: How much does it cost to get or renew and what is the 10-year rule?

Air travel is booming again, with more people expected to fly this summer, despite notably higher fares.

But UK holidaymakers travelling to the EU are being warned not to get caught out by the "10-year rule", which has stopped some passengers from flying.

Can I travel in the EU on my UK passport and what is the 10-year rule?

Some British holidaymakers have been turned away at the airport because their passports are not valid for EU travel.

UK travellers used to be able to carry up to nine months left on an old passport over to a new one. This meant that a passport could be valid for more than 10 years.

But the rules changed after Brexit, and the majority of EU countries no longer accept British passports that were issued more than 10 years before the date of travel. This is known as the "10-year rule".

To enter those countries now, your UK passport must:

• have been issued less than 10 years before the date you enter the EU country (the "date of issue")

• be valid for at least three months after the day you plan to leave (the "date of expiry")

If your passport does not meet these requirements, you will be refused entry.

British passports must be issued less than 10 years before the date you enter the EU country

The rules apply in all 27 EU countries, except Ireland, which has its own separate travel arrangements with the UK.

They also apply to passengers traveling to Iceland, Norway and Liechtenstein - which are part of the European Economic Area (EEA) - and Switzerland.

When should I renew my passport?

You must renew your passport before you travel if either:

• your passport has expired

• your date of issue was more than 10 years ago (if travelling to countries with the 10-year rule)

• your passport does not have enough time left before it expires

How much time you need on your passport depends on where you are going.

You can check entry requirements for individual countries on the UK government's website.

How do my I renew my passport?

You can renew online at HM Passport Office or by filling in a paper application from certain Post Offices.

You'll need your old passport and any valid passports you hold from a different country.

For online applications, you'll also need a digital photo that meets specific requirements. For paper applications, you need two identical printed photos.

The rules are different if you are renewing a passport for a child, your passport has been lost, stolen or damaged, or you need to change your name or personal details.
