GLL (formerly known as Greenwich Leisure Limited)  celebrated its 20th birthday in 2013 and also its success as the UK’s first, and now largest, leisure trust and social enterprise.

Originally established as an employee-owned ‘spin-out’ by Greenwich Council in 1993, the social enterprise model enabled GLL to grow and diversify, while remaining true to its community-focused ethos.  GLL has expanded its customer base by reaching out to all sections of society – with flexible pricing strategies and targeted community programmes that get residents of all ages, genders and races taking up new active pursuits on a regular basis.

Today, GLL oversees the management of over 110 public leisure centres in partnership with around 30 councils and other organisations.  It is also diversifying into new areas: GLL now runs libraries, parks, adventure playgrounds, and sports development programmes.  GLL is also investing in affordable health and beauty services through its Spa London product, alongside a growing chain of budget gyms.

2013 saw GLL continue its role delivering the Olympic legacy for London, operating world-class venues on the Queen Elizabeth Olympic Park – with its partner, the London Legacy Development Corporation.  The 20th anniversary of GLL coincided with the reopening of the Copper Box as a 7,000 capacity entertainment and sporting venue. Proof that the Olympic legacy is alive and well.

Mark has always worked within the leisure industry, joining as a trainee manager at the Riverside Centre, Stafford in 1977 straight from College. He was a public sector employee for 16 years before taking the opportunity, with colleagues, to launch GLL and taking over the operation of Greenwich’s leisure centres in 1993.
