For those who haven't played over in GB&I we have 2 types of private club;
Proprietary clubs owned by a person or business which allows members, pay and play societies and often weddings and the like. Examples would be The Addington, Wentworth, Loch Lomond, Gleneagles & Archerfield.
The vast majority of private clubs are private members clubs. The members own the club and usually the land and buildings. The club is "run by and for the benefit of the members". Most members clubs allow visitors usually Mon-Fri although many also have a ladies day when visitors are restricted. Private members clubs tend to be golf facilities only. Visitor income would usually amount to around 20-25% of turnover although clubs on the tourist route could be as high as 70-80%.
There are some totally private members clubs such as Glasgow GC, Wisley and Swinley Forest.
Annual fees tend to range from around £500 in more rural areas to £2000 for top south east and London courses. I would guess the average annual fee nationally is around £800-£900 or $1600-$1800 US. There is no monthly spend although many clubs add a modest £50-£100 a year to members bar cards.
I hope this helps your voting!!
