Following the terrorist attack on London Bridge and at Borough Market, and the tragic deaths that resulted, it is appropriate that flags should be flown at half-mast on Sunday, Monday and Tuesday. Further guidance should be issued by HM Government on Monday.
In the UK you are free to fly the national flag at half-mast whenever you feel it is appropriate. Any other national flags should be removed, and all other flags in the same set must be at half-mast. If it is not physically possible to fly the flag at half-mast, for example it is on an angled pole projecting from the building, then you can add a black cravat or ribbon to the top of the flag, nearest the flag pole.
Full guidance on flying flags at half-mast can be found in our booklet “Flying Flags in the United Kingdom”, which can be downloaded free-of-charge from this website.
Our thoughts and prayers are with the people of London and the families and friends of those killed and injured in this terrible event.
