As a live music venue Y Plas has a capacity of 1000 or 1200. It can be accessed via the steps at the front of the Union on Park Place. It is also where our clubnights take place with the addition of two other rooms. Y Plas has one large bar in the main room, a smaller bar on the mezzanine balcony and two bars in the other adjoining rooms. There is also a cloakroom in the back room.

TicketSwap

We are partnered with TicketSwap, our official ticket reseller that enables fans to buy and sell unwanted tickets safely, and fairly to one another. Selling anywhere other than TicketSwap is strongly discouraged. If you are experiencing issues selling your tickets, please reach out to the TicketSwap Support Team.

Disabled Accessibility Information

We operate a bookable balcony for all shows for those who have special accessible requirements, however it is operated on a first come, first served basis due to capacity limitations. It is often the case that we are unable to facilitate requests made on the night, but we will always aim to do what we can. Due to capacity restrictions we can only reserve spaces for 1 user and 1 carer - if your requirements surpass this please let us know. 

To book a space on the balcony you must FIRST purchase a ticket for the show for yourself, we can then offer you a complimentary carer ticket when requested in advance using the form below. All tickets are subject to availability and capacity. If the balcony is full we will process a full refund for the ticket purchased so you won't be out of pocket. Please note carers may have a restricted view.  

Requests must be made via our easy online booking system. Click here to access the booking system.

Please be aware that bookings are on a first come first served basis, and we may not be able to accommodate all requests.
