The new passports will also feature updated security features, the Home Office said, including the latest anti-forgery technology – making them “harder to forge or tamper with”.
Migration and citizenship minister Mike Tapp said the redesign marked “a new era in the history of the British passport”.
“It also demonstrates our commitment to outstanding public service – celebrating British heritage while ensuring our passports remain among the most secure and trusted in the world for years to come.”
The government advised people to check the validity of their passport and, if needed, apply to renew them in good time ahead of travelling.
UK passports in their modern form, with a photo and signature, have been issued since 1915. The first security watermark was added in 1972 and machine-readable passports were introduced in 1988.
