He departed QPR on 14 January 2015. The departure of Laurent caused a "reaction" at Loftus Road, with the supporters questioning the club's commitment to its younger players. On 23 January, Rangers' Head of Football Operations Les Ferdinand revealed that he had been unable to convince Laurent that there was a pathway from the Development Squad to the first team.
On 14 January 2015, Laurent moved across West London to sign for Championship side Brentford on a one-and-a-half-year Development Squad deal for an undisclosed fee. He made his only first team appearance in the League Cup first round versus Oxford United on 11 August, playing the full 90 minutes of the 4–0 defeat. Laurent failed to feature in another first team squad before his contract was terminated by mutual consent on 1 February 2016. He made 21 appearances and scored five goals for the Development Squad.
Laurent signed for League Two side Newport County on a 28-day youth loan on 19 August 2015, which was later extended to 14 October. He made his debut (the first Football League appearance of his career) as a 74th-minute substitute for Scott Boden in a 3–2 defeat to Leyton Orient three days later. He made his first start for the club on 1 September, playing the opening 73 minutes of the Exiles' shootout defeat to Swindon Town in the Football League Trophy first round. Laurent was left out of incoming manager John Sheridan's first squad on 3 October and was recalled by Brentford five days later, having made four appearances.
