As Pontypridd was brought under the Cardiff Blues umbrella following the demise of the Celtic Warriors (although all games were still hosted at the Arms Park and there were no changes to region's club kit or badge) attendances for home Celtic League and Heineken Cup games rose to an average of 5,218 for the 2004–05 season. The lowest crowd was 2,799 for Glasgow's League visit in November, still the lowest crowd ever for the Cardiff Blues in a League or European match, while the highest was 10,186 for Gloucester's Heineken Cup visit in December.
