The venue is to undergo a major overhaul, which will cost £23 million more than first thought.

Restoration work on the North Street venue has already started but recent surveys have revealed structural, mechanical, electrical and engineering issues which, if left unattended, could lead to long term damage to the hall.

The blow means that major events booked for the coming months can’t be held at the venue. Affected shows include Jason Manford and Sarah Millican’s UK tours and the Grand Slam of Darts.

Council bosses have confirmed they are working with promoters to try and re-schedule the events elsewhere in the city. People with tickets would be contacted when the situation becomes clear.

Events are not due to return to the Civic until Autumn 2020.
