Work on planned new facilities at Saxon Pool and Leisure Centre is to start soon with contractors starting on site from Monday.
After securing a new leisure management contract for the centre, Central Bedfordshire Council is investing in it to improve the reception area and add a new two-court sports hall.
Work is set to last until the New Year.
Cllr Brian Spurr at Central Beds explained: “Of course we’ll be trying to keep disruption to a minimum during the works and people should be able to carry on going to their classes or go to the gym without too much inconvenience.
“If there are any issues please speak to leisure centre staff who can help but we hope people agree that it’ll be worth the wait.”
