To become a Freemason in the UK, you'll need to first locate a local Masonic lodge where you live, work, or study. Then, you can express your interest in joining and a representative will be in touch. If you are over 18, and believe in a Supreme Being, you can apply.
Freemasonry is fundamentally a self-improvement, volunteer association that teaches moral, intellectual, and spiritual lessons through three initiation ceremonies. Freemasonry's three degree are modeled after a craftsman's progress: Apprentice, Fellowcraft, and Master Mason.
As with all members groups, becoming a freemason does incur some costs. Initially there is a registration fee that has to be paid to United Grand Lodge of England, although this is a one off cost. At present that fee is £115 but does include a charitable donation for Grand lodge funds..
