The group was originally a stable known as British Strong Style made up of Dunne, Bate, and Trent Seven, who last worked for WWE in the NXT UK brand, before his release in August 2022.

Though primarily appearing in Progress, the stable has also worked for several other promotions in the United Kingdom, including Chikara, where they won the 2017 King of Trios tournament.

The match ended with Pete and Seven turning on their partners and walking off together, signaling the start of a new partnership,[5][8] which they subsequently dubbed "British Strong Style".

[9] On 25 September, Dunne and Seven defeated the London Riots (James Davis and Rob Lynch) for the Progress Tag Team Championship.

They did however allow Bate and Seven to wrestle for the vacant title, leading to a match on 30 December, where the two defeated the London Riots and LDRS (Marty Scurll and Zack Sabre Jr.) to become the new champions.

[16][17] The trio were not acknowledged by WWE, instead Bate and Seven were referred to by the Moustache Mountain name,[18] with Dunne being positioned opposite the two as the main villain of the tournament.

[14][23] On 23 April, British Strong Style faced off against the Ringkampf stable of Axel Dieter Jr., Timothy Thatcher and Walter from the German Westside Xtreme Wrestling (wXw) promotion in a six-man tag team match, where both of their Progress titles were on the line.

[24][25] The following month, British Strong Style found themselves new rivals in the #CCK stable of Chris Brookes, Kid Lykos and Travis Banks, who debuted by interrupting their attack on Matt Riddle.

At Chapter 82, a rematch of the WWE United Kingdom Championship match from NXT TakeOver: Chicago between Dunne and Bate was the main event.

Dunne defeated Bate in what ring announcer and co-owner Jim Smallman said was the duos farewell match, implying both seemingly were going full-time with NXT UK and WWE.

[36] In April during WrestleMania Axxess weekend, Bate and Seven lost an NXT Tag Team Championship match to Strong and Kyle O'Reilly.

[41] New Catch Republic won the Undisputed WWE Tag Team Championship Contender Series for an Undisputed WWE Tag Team Championship match at Elimination Chamber: Perth but failed to defeat The Judgment Day (Finn Bálor and Damian Priest) for the titles at the event.
