Another difference with the UK days is that on Saint Andrew 's Day , the Union Flag will only be flown if the building has more than one flagpole - the Saltire will not be lowered to make way for the Union Flag if there is only one flagpole . A further Scottish distinction from the UK flag days is that on Saint Andrew 's Day , ( 30 November ) , the Union Flag will only be flown where a building has more than one flagpole - the Saltire will not be lowered to make way for the Union Flag where a single flagpole is present .
