Bank of England, Scottish, Northern Irish, Channel Islands, Isle of Man, Gibraltar, and Falkland banknotes may be offered anywhere in the UK, although there is no obligation to accept them as a means of payment, and acceptance varies. For example, merchants in England generally accept Scottish and Northern Irish bills, but some unfamiliar with them may reject them. However, Scottish and Northern Irish bills both tend to be accepted in Scotland and Northern Ireland, respectively. Merchants in England generally do not accept Jersey, Guernsey, Isle of Man, Gibraltar, and Falkland notes but Isle of Man notes are generally accepted in Northern Ireland. Bank of England notes are generally accepted in the Falklands and Gibraltar, but for example, Scottish and Northern Irish notes are not. Since all of the bills are denominated in pounds sterling, banks will exchange them for locally issued bills at face value, though some in the UK have had trouble exchanging Falkland Islands pounds.
