No, "normal" members of the general public cannot get married at Westminster Abbey. This historic site is a "Royal Peculiar," meaning it is under the direct jurisdiction of the Monarch rather than a local bishop. Marriage eligibility is strictly limited to three specific groups: members of the British Royal Family, members of the Most Honourable Order of the Bath (and their children), and individuals who actually live within the Abbey’s precincts (a very small group of clergy and staff). Even for those eligible, the "wedding season" is extremely limited, with usually only a handful of ceremonies occurring each year. For everyone else who dreams of a similar gothic atmosphere, the nearby St. Margaret’s Church—located right next to the Abbey—is a more accessible option, though even there, you typically need a strong connection to the parish or the Houses of Parliament. For the average person without "blue blood" or high-ranking military honors, the Abbey is a place for visiting and worship, not for exchanging vows.
