Another way to visit for free is to find out if there are any special exhibitions on by checking the official website. I visited an exhibition in Westminster Hall and it was easy to gain access so don't be intimidated by the security lines for tours. Simply explain to a member of staff by the Cromwell Green visitor entrance that you would like to see the exhibition (name it, if you can) and you will not have to join the back of the line where people are queuing for tours or to attend a debate but you do need to go through bag checks. By visiting an exhibition in Westminster Hall you not only get to see inside the Houses of Parliament for free, but you can also use the well-priced cafe and clean toilets.
