On his return to Lakeside for the 2008 BDO World Championship he was drawn to face Adams again, in a repeat of their final from twelve months earlier, but this time lost 0–3. His form remained steady during 2008, reaching the quarter-finals of the Dutch Open and British Open and his debut at the Grand Slam of Darts saw him lose 4–5 to James Wade in his first group game. He then defeated Niels de Ruiter, but allowed a 4–0 lead and a total of eight match darts slip and lost 5–4 to Pat Orreal, failing to qualify for the knockout stages. Nixon was also knocked out at the Group Stage of the 2008 Grand Slam of Darts, losing to Phil Taylor and Vincent van der Voort but defeated Andy Jenkins though it was too late for Nixon to qualify.
