Glenalla’s congregations dwindled after the Second World War, and continued to decline until it was forced to close in 1987. By the time closure came, the condition of the building had greatly deteriorated.

The Chapel was bought by the Town Council in 1987, and in 1991 a full restoration scheme was completed to create a splendid Civic Hall which retains the quintessential character of the original building. The adjoining former Chapel schoolroom was converted into a community centre. The restoration scheme was recognised by a Prince of Wales Committee Award for the restoration of historic buildings.
