Essential event information

The House of Commons forms part of the Palace of Westminster, which remains a Royal Palace; is one part of the legislature of the United Kingdom; a grade I listed building, and part of a UNESCO World Heritage Site. As such, the many considerations of planning an event here can seem complex and overwhelming at times.

Download key information which we feel will help you better understand some of our many rules and regulations and assist you in planning key elements of your event, giving you peace of mind.

Event Planner

When is what needed in the planning process? Our handy flow chart tells you what happens administratively and when in the lead up to your event from when the pre-payment has to be paid to when you must submit your menu choices.


All attendees, including organisers and their entourage, entertainment, photographers, etc., must be in possession of an official invitation (whether an electronic or hardcopy version), to be shown on demand to HOC Security. This will form part of the entry procedure at the pedestrian search points.

You may be asked to show proof of identity. Invitations should direct guests to arrive via Cromwell Green, unless specifically told to use one of our other entrances.

Style and formatting is very much a decision for event organisers.

The Crowned Portcullis Badge

The Portcullis surmounted with a Crown, the emblem of Parliament, can only be used on invitations for events sponsored by Members of Parliament and Members of the House of Lords.

Any APPG that is on the Register of APPGs must use the House's bespoke logo for APPGs if it wants to use the Crowned Portcullis badge on their invitations. Unregistered groups are not allowed to use the bespoke logo.


Need something delivering for your event? Then this must go through our secure off-site screening centre. We cannot take delivery of anything that has not already been through our security screening (including couriers).

Please ensure you choose 'Delivery Location 55. HoC Events' when completing the booking form.

Booking Agents

The House of Commons offers 8% commission on the net room hire, net food and beverage spend invoiced for commercial bookings generated from event agents. This is only applicable to agents placing the initial enquiry through to conclusion of the event.

Commission is not payable on Member-hosted events.
