Stop Bridge Leisure Centre from disturbing the peace

The Bridge Leisure Centre is a well-used leisure facility in Southeast London. What it is not is a nightclub, and yet that is how it is used almost every Saturday and often Sunday nights. The pounding bass from the music is impossible to shut out and usually doesn't end before midnight, at which time we are serenaded by people leaving the venue, yelling and honking car horns. The room that the parties are held in is totally unsuitable for loud music as it's completely glassed in, meaning there is zero soundproofing. You might think we live on a high street but no, we live in a normally quiet, residential area well off the main roads. So why is this allowed to continue? We've complained to the local council and Centre staff were given a warning, at which point they say they installed 'limiters'. What good are limiters if it means we are still subjected to the pounding bass? Please help us to stop this once and for all by putting an end to this type of event at the Centre.
