There are a range of toilet facilities throughout the Parliamentary estate which unescorted visitors can use.
The main public toilets are situated near the entrance to Westminster Hall next to the Jubilee cafe. Other toilet facilities are available to visitors elsewhere on the Parliamentary estate. There are toilets based in the lower waiting hall just off Central Lobby and also in St Stephen's hall (ladies only). For visitors to Portcullis House, toilets are available on the first floor.
