2017–18 Premier 15s
|Number of teams||10|
The Premier 15s, currently known for sponsorship purposes as the Tyrrells Premier 15s, is the top tier of the women's English rugby union domestic league system run by the Rugby Football Union (RFU). The league was created mainly from teams in the Women's Premiership. Its first season began on 16 September 2017. Reigning champions are Saracen Women.
The Premier 15s was founded by the RFU in October 2016 as Women's Super Rugby, where teams involved would have to invest in training facilities and meet increased minimum standards. The RFU will invest millions of pounds in the clubs over the first three seasons to help develop the improved standards. A minimum requirement in the new league included developing a professional coaching resource to support players in training throughout the week.
There will be no promotion/relegation to the Premier 15s during the first two seasons.
When the new league was announced, the RFU announced an independent bidding process for women's teams who wished to run one of the franchises, with the initial plan being for all previous Women's Premiership teams plus two new teams to make up the league. Following the initial 14 clubs making submissions of interest, 12 were invited for an interview at Twickenham Stadium.
In February 2017, the RFU announced the 10 clubs that would partake in the new league. The choice was controversial as all Women's Premiership teams (Aylesford Bulls Ladies being taken over by Harlequin F.C. and became Harlequins Ladies) were included except for Lichfield Ladies despite their 15-year stint in the top flight of English women's rugby. In their place were clubs that had never participated in the Women's Premiership including Gloucester-Hartpury Women and Loughborough Students (Lightning). The Lichfield Ladies director of rugby said: " “We're disgusted, disappointed and dumbfounded by the decision." A number of high-profile figures also protested at the exclusion of Lichfield including the men's Leicester Tigers and the Conservative MP for Lichfield, Michael Fabricant said he would challenge it in Parliament, citing the Equality Act 2010 in that the men's English Premiership had 12 teams while the Women's Super League only had 10. The champions of Championship 1 South, Thurrock T-Birds also said that they would appeal against their exclusion from the new league. However, both appeals were unsuccessful.
All teams play a home and away season with the top four teams qualifying for a play-off using the 1v4, 2v3 system. Unusually, for the 2017-18 season, each of the play-offs comprised back-to-back home and away fixtures with the aggregate score across both determining the winner. For the 2018-19 season, the play-offs reverted to the more usual single fixture with the top two teams having home advantage. The two winners play in the final.
