Ford cars from the 1960s until a major accident at Oulton Park in 1975 ended his career. Wilson's younger brother, Stefan, is also a racing driver. He grew up in Woodall, South Yorkshire. From 1989 to the completion of General Certificate of Secondary Education (GCSE) examinations in July 1994, Wilson was educated at Sheffield's private Birkdale School. At age 11, he was tested for dyslexia, a learning disability that affects how a person reads and writes words; the test was negative. Wilson's mother took him to a clinic for a second test two years later and he was formally diagnosed with the condition at the age of 13. He struggled at school with the disability and received additional tutoring; Wilson's peers perceived him as inept and unintelligent. He married his partner Julia in 2006 and they have two children, Jane and Jessica. Wilson was the official ambassador for the International Dyslexia Association, and Teen Cancer America. Junior career Aged 8 in 1987, Wilson sought a hobby and took up karting, refining his ability at the South Yorkshire Kart Club in Wombwell, Barnsley.

In 1989, Wilson finished 7th in the Cadet National British Karting Championship, 12th in the 1991 RACMSA Junior British Championships, improving to 4th in 1992. His father contacted karting expert Terry Fullerton in 1993 and the two met at the Worksop motorway services. Fullerton told him Wilson should cease karting in his category because of his weight, and mentored him in 1994. Wilson finished fifth in the 1994 Formula A British Championship, the United Kingdom's highest-level of kart racing. He was third at Buckmore Park Kart Circuit's Renault GP race. He progressed to car racing at age 16, competing in the Formula Vauxhall Junior Winter Series with Team JLR, as preparation for the 1995 Formula Vaxuhall Junior Championship.
