He moved to the Lierse academy at the age of eight, progressing through the youth teams before making his senior debut in 1992 under head coach Herman Helleputte.

The striker scored eight goals and formed a striking duo with Dirk Huysmans, in a Lierse-team counting profiles such as Nico Van Kerckhoven, Philip Haagdoren, Eric Van Meir and David Brocken which won the Belgian First Division A title in the 1996–97 season.

[1] In January 1997, Peeters was in contract negotiations with the Lierse board, but chose to leave, according to him because he was seen as a "tall, clumsy" striker.

[2] After winning the league title with Lierse, Peeters signed with Dutch Eredivisie club Roda JC under the Bosman ruling.

There, he was united with fellow countrymen Joos Valgaeren, Gregory Delwarte and Peter Van Houdt.

[3] In his first season, the club from Kerkrade finished fourteenth, but after the arrival of manager Sef Vergoossen, Roda returned to mid-table.

Peeters opened the score after 18 minutes after heading in a free kick from Eric van der Luer.

[9] Peeters signed a three-year contract with English Football League First Division club Millwall on 20 August 2003, where he was set to replace regular target-man Mark McCammon.

[11][12] In 2005, Peeters was poised for a return to Belgium,[13] and after negotiating with Westerlo, he eventually signed with Genk after being convinced by technical director Ariël Jacobs.

[17][18] Peeters made his debut for the Belgium national team on 25 February 1998 in a friendly against the United States, which was won 2–0 thanks to a brace by Nico Van Kerckhoven.

His Senior Professional Development Coach Patrick Van Houdt and Performance Analyst Guy Kiala were also fired.

Peeters' main goal in the 2015–16 season was avoiding relegation, something that he succeeded in on 13 March 2016 by winning 1–0 against Waasland Beveren.

[24] Westerlo's last victory dated from 30 September that year, after which the club only gained three points out of 30 under Vedran Pelić, who later stayed on as assistant to Peeters, together with Eric Reenaers.

In November 2018, Peeters was linked to a return to Waasland-Beveren, but in the end he stayed with Westerlo after the club offered him a contract extension until 2023.

[31][32][33] After a draw against Club NXT on the final matchday, Westerlo ended in fourth place, nine points behind Seraing.
