OP who did you complain to within the social club? And what time was it when you complained?
If you just went in and complained at the bar staff or doorman or customers in general then nothing really would be done about it.
I think most social clubs have a committee and you could put your complaint in writing to them. Most clubs I know take these complaints seriously but usually only deal with them if they have been made in writing and can be discussed at a committee meeting (held fortnightly/monthly in my experience)
Otherwise, complain to your local council if you think the club has broken it's licensing agreement.
If the club is registered to the CIU then you could also complain to them.
That's assuming your complain is reasonable. In my experience noise outside is restricted after 9pm but when they have live music inside it can still be heard outside until about 11pm.
If you are complaining in the afternoon then they might be within their rights to play music outside.
I spent a good bit of my life growing up in flats above clubs or houses next door to them, as my parents still run one. They run the bar, but a committee is responsible for the rest of the club, including things like music licences and extensions to normal hours on special occasions etc.
They would take a complaint seriously if it was reasonable, but again, it's better to have it in writing. There's a very tall man who lives opposite the club, who very occasionally comes in and shouts very loudly for the person blocking his driveway to come out and move their car. The club take that seriously and always have words with anyone caught doing it (and it's very rare that it happens now because of that). They also have signs up asking people to be considerate of the local residents and have stopped all drinking or smoking outside the front doors from 9pm onwards.
It has to be a bit of give and take on both sides when you run a club in a residential area or buy a house next to an established social club. But if you really feel they are causing a public nuisance with noise which breaches their licence agreement or are being given extensions to normal business hours that are intruding on you late at night, speak to your local council.
