Wakefield Town Hall will close for more than a year after it was found to be in urgent need of a new heating system.
And people will be directed to Wakefield One, on Burton Street, or County Hall, on Bond Street, if they need to contact the council.
The council said the current state of the heating system was causing high running costs.
Coun Graham Stokes, cabinet member for corporate services, said: “We apologise for any inconvenience caused when the town hall temporarily closes. This maintenance is essential to ensure that this historic Wakefield building is in good condition and fit for purpose for many years to come. The cost of the repairs has already been budgeted for so will not impact on key services.
“We will also be using this as an opportunity to make vital savings in the longer term as the refurbished heating system will also improve the performance of the building in terms of energy efficiency and reducing carbon emissions.
“The town hall is a valued public resource and popular wedding venue. Annual civic events, meetings and celebrations will be accommodated within alternative council venues across the district.”
While the town hall is closed it will also benefit from electrical works, redecoration and improvements to security.
