From 01.10.2021, German citizens will require a valid passport to enter the United Kingdom (UK). Identity cards will no longer be recognised as entry documents from 01.10.2021.
These changes also apply to nationals of most other EU member states, the European Economic Area (EEA) and Switzerland.
Exemptions from the passport requirement apply to people who are resident in the UK and have "Settlement Status" or "Pre-Settlement Statuts" under the EU-Settlement Scheme (EUSS), are cross-border workers or are "S2 Healthcare Visitor". These people can still use their ID card to enter the UK until 31.12.2025.
Travellers with invalid or insufficient travel documents should expect to be refused entry to the United Kingdom (UK) at the border.
Airlines are obliged to check that passengers have the travel documents required to enter their country of destination. If they do not, this will result in the airline refusing carriage due to insufficient travel documents.
The LBA recommends that passengers inform themselves about the entry regulations of their destination country before their flight.
Information on this can be found, among other places, on the website of the Federal Foreign Offfice (only in German).
