Radcliffe, 22, remains in his top spot on Heat magazine’s 30 Under 30 Rich List, with a total earnings of £51.8 million.
Twilight star Robert Pattinson did not manage to eclipse his former Harry Potter cast-mate.
Pattinson, 25, doesn’t even come in second place with his £24.9 as the third-richest young UK celebrity. He did manage to push Harry Potter co-stars Emma Watson, 21, and Rupert Grint, 23, into fourth and fifth places respectiively.
The Twilight star may take over the Potter star in 2012 as the second installment of Breaking Dawn, and the final movie in the series, is due to hit theatres.
The number two spot on the Rich List is maintained by Keiira Knightley, 26, who has an estimated wealth of £30.9 million.
The highest new entry on the list was Adele, 23, at number sixteen. She has an estimated wealth of £7.7 million. She was joined on the list by newly wealthy Florence Welch with £3.8 million at spot number twenty-nine.
Singer Charlotte Church, who appeared at the Levenson Inquiry yesterday, fell three places to number ten.
Cheryl Cole, boosted by her L’Oreal adverts, climbed the the list to a number seven spot with her £11.4 million.
