British nationals do not need to register at British Embassies to receive consular support and information. Information about our services is available on Consular services - GOV.UK. People needing assistance can contact us by telephone 24/7 by calling the Foreign and Commonwealth Office (FCO) in London or a British Embassy or Consulate overseas. Our operators provide information and advice about the consular services available. Where they are unable to help the caller to resolve the issue themselves, and/or when they judge that the caller needs urgent assistance, they will pass the call to the nearest embassy, or, if the embassy is closed, to our Global Response Centre in London.
The FCO encourages people to subscribe to FCO travel advice email alerts "living in” guides, follow FCO Travel on Facebook and @fcotravel on Twitter for updates and to follow the nearest British Embassy, High Commission or Consulate on Twitter and Facebook. FCO travel advice is updated frequently during a crisis and is often the best source of information and advice for those affected.
