Career
During his time on the National List he was based in Mossley, Lancashire. Dilkes became a Football League linesman in 1980 and reached the Referees List just three years later at the age of thirty four. In March 1988 he handled the Merseyside derby between Everton and Liverpool.
This would be a key match in any circumstances but took on far greater significance as Liverpool were aiming to set a (then) record of thirty matches unbeaten from the start of the season.
He continued to receive good appointments, many in the old First Division, as well as Lancashire derbies. When more opportunities arose in 1992 he was then too old according to Fédération internationale de football association"s newly introduced age criteria.
Dilkes was nevertheless chosen as one of the first set of Premier League referees for the 1992-1993 season, and he retained this position for the final five years of his career. This period also saw him handle his most senior Cup appointments.
The pinnacle was an semi-final in 1994 between Chelsea and Luton Town.
Two years later he officiated in a League Cup semi-final second leg as Leeds United overcame Birmingham City.
