In November 2002, Wagstaff celebrated his 60th birthday at the
Ramada Jarvis Hotel in
Willerby with 350 friends, including players from the Hull City 1965–66 Third Division championship team. Author John Maffin wrote a biography about Wagstaff,
Waggy: The Ken Wagstaff Story. Wagstaff co-operated with the author and the book was published in 2002 with a second edition published in 2004. In 2005, as part of Hull City's club centenary celebrations, Wagstaff was voted by supporters as the "best Hull City player of all time". After retiring from his football career, Wagstaff ran The Golden Ball pub (since demolished) and then bought The Marlborough club, affectionately known as "Waggies". He has since sold the club and retired, In 2006, he participated in the
Sport Relief Mile in Hull to raise money for marginalised people, and in 2007, he took part in a charity golf tournament at
Bridlington Belvedere Golf Club. Wagstaff's wife Eileen died from breast cancer in August 2007. In February 2008, Wagstaff and his family raised money to start a lifestyle centre in her memory at the Princess Royal Hospital in Saltshouse Road, east Hull. The centre would provide breast cancer patients with diet and lifestyle advice. After a brief stint during 2009 running the Roos Arms, a village pub in
Roos,
East Riding of Yorkshire he has since completely retired to spend more time with his family and now lives in Hull. ==Honours==
