The 2001-2002 Powergen Cup was the thirty-first edition of England's rugby union club competition. London Irish won the competition defeating Northampton Saints in the final. The event was sponsored by Powergen and the final was held at Twickenham Stadium.
The 2005-06 Powergen Cup was the 35th annual rugby union cup competition in England. Originally contested between clubs of the English leagues, this was the first season for which the competition was open to the Welsh regions, forming the Anglo-Welsh Cup. The cup is contested between the twelve teams of the English Premiership and the four Welsh regional sides from the Magners League. The format of the cup is similar to that of the Heineken Cup, beginning with pool stages, with the top placed teams entering knockout stages. Each pool consists of a Welsh region and three English sides, with each team playing the others in the group once, and the top team of each group advancing to the semi-finals.
Pool matches were played in September, October and December 2005. Bath Rugby, London Wasps, Llanelli Scarlets and Leicester Tigers emerged as winners of their respective pools. London Wasps defeated Llanelli Scarlets 26 points to 10 in the final at Twickenham Stadium on April 9.
The 2004-05 Powergen Cup was the 34th annual rugby union cup competition in England. Leeds Tykes (now named Yorkshire Carnegie) won the competition for the first time in their history. The event was sponsored by Powergen and the final was held at Twickenham Stadium.
This was the last season in which the competition was confined to English teams only; from the 2005-06 season, the Welsh regional teams joined to form the Anglo-Welsh Cup. This season also marked the last time that teams outside of the English Premiership were permitted to enter.
Earlier rounds of the competition were run on a seeded system. Earlier rounds included Clubs which were lower in the RFU league structure, clubs higher in the leagues joined at later rounds.
The Qualifier Round consisted of 64 Clubs nominated by the Constituent Bodies (CB). Each CB nominated 2 Clubs, or 3 for the larger CBs such as Middlesex and Lancashire. These teams were usually selected through the previous season's County Cup (CB Cup) competitions. All were Level 5 or below. This Round produced 32 teams for the next round.
