Placed in the eighth tier of English rugby with the advent of the English rugby union league competition, the club were able to build a strong team due to extensive financial support from their backer and chairman Cecil Duckworth, being promoted repeatedly through the league system.

[4] The contracts of all players and coaching staff were terminated on 5 October 2022 following the granting of a winding-up petition from HMRC in the High Court.

[5] After starting to manage the Warriors, James Sandford and Jim O'Toole announced that the team might not play games again after an earlier administration.

[6][7] On 9 February 2023, it was announced that the club had been disbanded and that its administrators were trying without making Stourbridge RFC decide to play their games at Sixways Stadium in their place – something that was not successful.

In 2006, extremely ambitious plans were announced for a £23 million development programme, which would see a health club with fitness centre and swimming pool, fully tarmacked park and ride area, and expanded capacity to 11,499.

They were the bookies', and many of the rugby pundits' odds-on-favourites to go straight back down but defied the odds to stay in the Premiership for another season, finishing ninth in the league, after wins against teams including Harlequins, Leeds, a historic victory against Premiership Champions London Wasps and Northampton in a 'winner takes all' end of season finale, which they won 21–19.

In the 2004–05 season, despite Premiership survival being their ultimate aim, they reached the final of the defunct European Shield at Oxford's Kassam Stadium, after beating Leeds Tykes in the semi-final.

They also managed to achieve a play-off match for the Heineken Cup against Saracens, but their long fight for Premiership survival and an injury-ravaged squad meant that they lost.

In the 2006–07 season Worcester didn't get off to a very good start and for the majority of the season they were positioned in 12th place, but a good run of form which involved beating some of the top sides in the Premiership, helping them to avoid relegation and send the former Heineken Cup champions Northampton Saints down into National Division One.

While they were struggling in the premiership they were enjoying good success in the European Challenge Cup (ECC), progressing through the group stages.

After Christmas their premiership form picked up and they beat top teams such as Leicester Tigers and Sale Sharks, which subsequently saw them move out of the relegation zone, Leeds Carnegie replacing them.

They progressed even further in the ECC and beat off Montpellier Hérault RC in the quarter-final and saw off Newcastle Falcons in the semi-final which set up a final against Bath.

[11] The season again didn't go the way it was planned but Worcester still progressed in the ECC and pulled off home and away victories over local rivals Gloucester and London Wasps in the league.

However the season ended disappointingly (after Worcester suffered a succession of serious injuries), losing in the semi-final of the European Challenge Cup to Bourgoin.

[15] Warriors achieved promotion back to the Premiership at their first attempt, beating Bristol in the playoffs thanks to a last minute Chris Pennell try and Ryan Lamb conversion.

[18] The club also made a number of high-profile signings in Francois Hougaard, Donncha O'Callaghan and Wynand Olivier and finished the season in tenth position after winning seven games.

[27] On 16 December 2022, the RFU rejected the club's plans for a return to the Championship in 2023–24 due to the prospective buyers selected by the administrators being unable to fulfill given conditions.

Due to both teams consistently doing well in the league, and tensions between the two clubs being high off the pitch, the games often attracted bigger crowds and greater media interest than usual.

However, the second half was a completely different affair, with Worcester's Chris Garrard sent off for a dangerous tackle on Jacob Raulini, and Steve Caine sin binned.

Rotherham, spurred on by their biggest and most vociferous crowd of the season, scored 32 points, including four tries, and conceded none, to complete a demolition of Worcester.

That was predominantly because of playing them regularly since gaining promotion to the Premiership in 2004, the geographical closeness of the two cities, and various media sources citing the game as a derby.

[35] Their main shirt sponsor is Adam Hewitt Ltd.[36] In 2019, the club signed a multi-year deal with Aramis Rugby to supply digital scrum machines.
