Unincorporated association
You can be constituted as an unincorporated association. All you need to do is draw up and agree a constitution to help your group run smoothly.
Because you don’t need to be a charity or have limited liability, you don’t need to worry about registering with any external organisations such as the Charity Commission or Companies House. You can just get going!
