Common Bond, the parent company behind Barrecore, Boom Cycle, KOBOX, Reformcore and Triyoga, has shut all of its London studios 'until further notice', leaving members who paid up to £2,400 for annual unlimited packages and staff facing uncertainty over the future of the fitness group.

Members were informed of the closure by email on Wednesday. The company apologised for the disruption but did not provide a further explanation for why the studios had been shut.

The closure affects venues across the capital, including Triyoga studios in Camden, Chelsea, Shoreditch and Westminster. Barrecore and Reformcore sites in Aldgate, Chelsea, Hampstead, Notting Hill and Wandsworth are also affected.

Boom Cycle locations in Battersea, Hammersmith, Monument and Shoreditch have closed, along with KOBOX studios in Chelsea, Liverpool Street and Marylebone. Common Bond's website has also become publicly inaccessible.

Common Bond had been selling 12-month unlimited class memberships for £2,400. Members with those packages were among the customers contacted about the sudden closure this week.

The shutdown means customers with prepaid memberships may now be seeking information about access to classes and the status of their payments. The company has not publicly provided further details on what will happen to affected memberships.

The closure follows claims from hundreds of instructors and studio employees that their monthly wages were delayed or not paid. In mid-August, instructors reported delays in receiving payment for classes they had already taught.

Triyoga later missed staff payments that month, with the outstanding wages eventually transferred after workers threatened industrial action.

On 10 September, Common Bond told Triyoga staff that payments due on 17 September would be delayed by three to four days while the company underwent an audit on behalf of its main investors. The payments due on 17 September were then not made, according to staff.

Triyoga staff threatened industrial action after a missed payment, before the company agreed to transfer the outstanding wages. The latest missed payment has added to concerns among employees about how the group is operating while its London studios remain closed.

More than 100 Triyoga employees have approached the Independent Workers' Union of Great Britain (IWGB) for help recovering unpaid wages, following the latest missed payment. The involvement of the union adds to the pressure facing Common Bond as employees seek to recover money they say they are owed.

It remains unclear whether the latest closure and reported wage delays are connected beyond occurring within the same period. Companies House filings show that Ben Allen resigned as a director of Common Bond last month.

Gaspar Lipszyc, a Spain-based Belgian national, is now listed as the company's sole director. He has been named in other reports as a principal at investment firm Nectar Capital LLP. The change leaves Lipszyc as the only director currently recorded on the company's public register.

Triyoga, one of the brands operated by Common Bond, has previously counted model Kate Moss and actor Jude Law among its clientele. The chain is part of a wider group of boutique fitness brands covering yoga, reformer pilates, indoor cycling, barre and boxing-inspired workouts.

Common Bond was founded in 2025 and is based in London. The company operates its brands through separate studio concepts aimed at customers looking for group fitness and wellness classes.

At the time of writing, the company has not issued a further public explanation for the London closures beyond the email sent to members. Its website also remains inaccessible.

The company is listed among hundreds of competitors in the luxury fitness sector. Its listed rivals include WildTraining, LighterLife and Energize Fitness.
