Construction company Beard Construction will be on-site from Monday, November 4.
Cllr Ian Blair-Pilling, Wiltshire Council’s cabinet member for leisure, said: “I am pleased to confirm when work starts on the significant improvements to Warminster Sports Centre, which will make the fitness facilities more modern and accessible and will encourage more people of all ages to access them.
“The plans for Warminster Sports Centre have been well informed by evidence that shows there is demand for the enhanced facilities we will be providing.
“We have the unique responsibility to not only ensure this type of project is a viable commercial venture, but to also serve our communities and ensure their health and wellbeing is well supported.
“This investment, and the work we’re carrying out at some of our other leisure centres, meets all those needs and criteria, and we’re looking forward to the positive impact they will have.
“We thank our loyal customers for their patience while these works are carried out, and we assure that any disruption during this period will be well worth it come the end result.”
The council says a number of “significant changes” will take place at the centre, including relocating, enlarging and improving the fitness suite, making it much more accessible.
The council also intends to refurbish a studio, convert the old fitness suite to flexible community space, and provide a consultation room.
The existing gym will remain in use while the new gym is being constructed and there will be no change to swimming pool access or changing.
The council said: “There will be some disruption to group exercise classes during the project, with fewer classes available and classes being relocated to the main sports hall – but there will be more classes at Leighton Sports Centre in Westbury to offset this.
“There will be some reduction in car parking spaces throughout the project.”£
As previously confirmed, the squash courts will be permanently removed at Warminster Sports Centre as a result of the works.
Squash court players are being encouraged to use the facilities at Leighton Recreation Centre a short distance away.
The work at Warminster is due to be completed in spring 2025 and follows recent improvement works being completed at other Wiltshire Council leisure centres.
