British flag and language option for guests

As a business located in England and with most of our customers also being based in the UK we get several guests remark that the English option on the booking page only gives English (US) and displays a US flag.  A lot of websites I visit have an option for both UK English and US English.  Is this something OR could do, or at least include both US and UK flag against English?
