Olympic stars are set to open a town's long-awaited £20m leisure centre next month – but some clubs believe the facilities fall short of its sporting legacy.

The brand new White Oak Leisure Centre will open next month in Hilda May Avenue, Swanley.

Former Olympic sprinter and BBC commentator Colin Jackson is among the sporting stars lined up to unveil the new facilities.

This includes a 25m six lane main pool, learner pool, 100-station gym and fitness suite, two exercise studios, cycling studio, a sports hall and TAGactive, a brand new interactive gaming activity.

Free events are planned to mark the opening on Saturday, February 12, including a "Big Splash" day, a rookie lifeguard course and "dive and glide" sessions.

It will feature appearances from London 2012 Olympian, Adele Carlsen, synchronised swimmer, Kate Skelton, and British record holder and former Olympian in freestyle swimming, Grant Turner.

Visitors will also have the opportunity to try out football skills with Britain’s Got Talent freestyle footballer, Jamie Knight, and face painting.

The new White Oak Leisure Centre replaces the old facility, which is now closed. and is being managed by leisure operator Everyone Active in partnership with Sevenoaks council.

But not everyone is happy about the replacement which has seen certain sports clubs – including netball, roller hockey and others that require a larger space – turfed out.

Highgate Diving Club lays claim to being one of the oldest diving clubs in the world but has also now been forced to move.

It has been running for nearly 93 years – 40 of which were spent at White Oak – and has seen past members such as former world champion Chris Snode represent Team GB at the Olympic and Commonwealth Games.

Head coach Ian Cunningham said the club faced an uncertain future after struggling to find a replacement in Dartford, Tunbridge Wells and Maidstone.

He said: "It is sad for the Swanley and the residents because so many people used to come from outside the area because of the diving board and the flumes.

"They said in their area it was just a boring swimming pool. It is a great shame."

This month the club moved more than 20 miles to its new home at the Medway Park Sports Centre in Gillingham.

Mr Cunningham said it had managed to retain around half its members and hopes to recruit more locally.

He added: "It is now down to the parents to do the running about, as they would have been anyway, but now it is more of a commitment."

Sport England had also outlined rejections to the planning bid for the new White Oak centre which it said could lead to a reduction in fitness facilities.

Janet Payne, committee club member at White Oak, said the facilities fall short of the council's promise of a "like for like or better".

She had appealed to Sevenoaks councillors to retain the existing sports hall until alternative facilities were available for relocated clubs at the nearby Orchard Academy, as promised by the council.

The school, which is set to be rebuilt following a campaign led by Sevenoaks MP Laura Trott, has seen its auditorium and sports hall flood on three occasions since the summer.

"The Orchard Academy is going to be rebuilt but nothing is coming up for us sport-wise," said Ms Payne.

"We seriously believe the health and wellbeing of Swanley residents is being ignored. They have not done any favours at all for Swanley."

A decision to knock down the 53-year-old White Oak leisure centre comes after the building was deemed to be "reaching the end of its serviceable life" due to its age and condition.

Council chiefs vowed to press ahead with the revamp which it said was needed to reach residents not currently accessing sport.

Speaking ahead of the new centre's launch, Cllr Lesley Dyball, Sevenoaks council’s cabinet member for people and places, said: “The new White Oak Leisure Centre is the council’s biggest capital investment in a generation and an important milestone in Swanley’s regeneration.

"The town now has a fantastic, modern, energy-efficient leisure centre the whole community can be proud of with exciting new activities, including Tag Active, a swimming pool with a movable floor and a state-of-the-art gym.

She added: “We have also provided funding to Orchards Academy and are continuing to work with them to improve their sports hall facilities for community use”.

Hasan Romel, area contract manager at Everyone Active, added: “The centre will play pivotal part in helping the community to improve their health and wellbeing and so we’re really looking forward to being able to celebrate with an official open day.

“It will be great to see the local community benefitting from all the fantastic facilities we have on offer and hope they will join us for a weekend of fun-filled activities for the whole family.”

The centre currently has a founder membership on offer meaning anyone who signs up before or on the opening weekend will receive a membership for £29.99 instead of £34.99.

Activities for the open day need to be booked in advance online via the Everyone Active website. For more information or to sign up for a membership, click here.
