If it's a casual practice, a free room you already have will do; once you need a proper floor or mirrors, a hired studio earns its fee. A living room, a friend's garden or a community hall you already have access to can cost next to nothing, needs no public-space paperwork for a private get-together, and suits a casual practice or a small, low-key celebration. The trade-offs are real, though. You'll often be short on mirrors, a proper floor, changing space and parking, and you become the one setting up, cleaning and solving problems on the day.
A hired studio flips that. You get a floor built for movement, mirrors, a PA and a host who knows the room, but you're paying by the hour and working to a booking window. Public outdoor spaces sit somewhere in between and aren't the free option they seem. Hiring a park in a London borough such as the
Royal Borough of Kensington and Chelsea needs at least six weeks' notice for smaller events, and the council charges for handling each event application.
Licensing is the other quiet factor once music, dancing or alcohol enter a party. A licensed venue's operator already holds the
premises licence that covers regulated entertainment, whereas hosting the same do at a village or community hall can mean arranging a
Temporary Event Notice, which covers under 500 people, costs £21 and needs at least ten clear working days' notice. Weigh the admin against the savings and pick honestly. For a party with a proper dance floor, comparing
community halls across London is a sensible starting point.
Pro tip: Booking a private, already-licensed space on Peerspace usually spares you the public-space permit run-around, since the venue operator holds the premises licence for regulated entertainment. Message the host to confirm what their licence covers.
