Access to the flagpole on Portcullis House is currently denied on health and safety grounds so no flags are flown.
The St. George Flag is never flown on the parliamentary estate as each building on the Estate only has one flagstaff.
The House follows guidance from the Department for Culture, Media and Sport on these matters and this suggests that on St. George’s Day, where a building has two or more flagstaffs the appropriate National flag may be flown in addition to the Union flag, but not in a superior position.
