The following season the Pirates again won their semi-final, beating Bristol over two legs, 45–24 at home and losing 29–18 away, resulting in a 63–53 win on aggregate. Pirates again however lost in the final, this time to London Welsh, losing 21–37 at the Mennaye and 29–20 away from home, 66–41 on aggregate. Following these highs, Pirates did not finish in the play-off places again, finishing between 6th and 9th in the subsequent seasons. They returned to the top four in the 2017–18 season, finishing 4th, however a restructure to the league for that season had seen the play-offs abolished, with 1st place being promoted to the Premiership automatically. To be promoted to the Premiership a team must meet certain stadium requirements, and the capacity of the Mennaye Field is too small to meet these.
Because of this, there have been many plans over the years for the Pirates to move into a new, larger stadium which meets these requirements to allow the Pirates to achieve their goal of promotion to the Premiership. The most concrete of these plans is the proposed Stadium for Cornwall, which would be home for both the Pirates and Truro City Football Club.  The Stadium For Cornwall has received funding from Cornwall Council, and is now only awaiting £3m of funding from the UK government before construction can begin, which is expected to be provided in Spring 2019.
In 2009–10 the Pirates won the inaugural British and Irish Cup, beating Munster A 23–14 in the final at the Recreation Ground, Camborne. Pirates remain a solid RFU Championship side, their lowest finish since being 9th in 2015–16, with highs of 3rd in 2010–11 and 2011–12. These 3rd-place finishes resulted in Pirates qualifying for the promotion play-offs. In 2010-11 Pirates beat London Welsh in the semi-final 18–10 at the Mennaye Field before succumbing to Worcester Warriors in the final over two legs, 12–21 at home and 25–20 away, 46–32 on aggregate, resulting in Worcester's promotion back to the Aviva Premiership.
