To phone the UK government that manages British Embassies and High Commissions around the world (the Foreign & Commonwealth Office) you can call this number from outside the UK: +44 20 7008 1500.
If you are calling from inside the UK, use this phone number: 020 7008 1500.
When people outside of the UK want their friends in the UK to contact the British Embassy in the UK, they usually don’t realise that a British Embassy exists in almost every country EXCEPT the UK itself, because of course embassies are foreign bases. In some countries, there is a British High Commission office but just like Embassies there is no equivalent office in the UK.
If someone wishes to contact the UK central government body responsible for governing overseas embassies and high commissions, they probably mean to contact the Foreign & Commonwealth Office.
The UK’s Foreign & Commonwealth Office (FCO) is in charge of opening, closing, maintaining and assisting British Embassies around the world. They assign ambassadors to each country in which we have an embassy and they of course finance the whole affair.
