Starting his career in karting at the age of seven, Rowland spent a decade racing in various series around the United Kingdom before progressing to Formula Renault, taking a place on the grid of the 2010 Formula Renault UK Winter Series with CRS Racing. At the same time, the British driver received funding from the Racing Steps Foundation, which helped him graduate into single-seater racing. 

Moving to Formula Renault 3.5 in 2013, Rowland finished his campaign in fourth with seven podium finishes, before taking the championship title in 2015 with Fortec Motorsports. That same year, he made his debut in Formula E with Mahindra Racing, filling in for driver Nick Heidfield in the Punta del Este E-Prix where he finished 13th. 

After making his debut in GP2 in Silverstone the same year, Rowland competed in the series for two seasons, finishing third overall in 2017. Entering into Formula One in 2017, Rowland was signed to the role of development driver to the Renault F1 team. 

In 2018 the Sheffield-born driver was confirmed as Williams Martini Racing's official Junior Driver ahead of securing a full-time seat with Nissan e.dams.

Joining Formula E full-time after one outing for Mahindra in the 2015/16 season, Rowland partnered with Sebastien Buemi for the team's debut season. Finishing second in the teams' championship after six podium finishes, six pole positions and 16 Super Pole qualifying appearances, the team ended the season with its first ever victory during the final race weekend in New York, which went to Rowland's teammate Buemi.

In his second season with Nissan e.dams, Rowland put in a consistent run of point-scoring finishes across 2019/20 that culminated in a debut victory at the penultimate round of the season in the final Berlin double-header.

Heading into his third season in all-electric street racing, Rowland continues his strong partnership with Nissan e.dams alongside Sebastien Buemi. 

Season 7 was a slow burn, with bad luck curtailing the front-running pace - certainly for the Brit. Rowland rounded off with another podium at Tempelhof, adding to silverware in Puebla. Converting his London DNF after that tangle with Stoffel Vandoorne (Mercedes-EQ) could well have seen Rowland trouble the standings' top three.

Rowland moved to pastures new to complete another all-British driver line-up alongside Alexander Sims at Indian outfit Mahindra Racing for Season 8, following three seasons with Nissan e.dams. It was 14th again in the running, with a podium in Seoul the highlight.

The Barnsley-born driver stuck with Mahindra for Season 9 and struggled to remain competitive throughout the season. It proved to be a disappointing season for him as he finished towards the bottom of the Drivers’ Championship, after parting ways with the team midway through the campaign.

However, Rowland’s break from Formula E was short-lived, as he was back on the Season 10 grid with Nissan. The move to the Japanese manufacturer has paid dividends so far. The British driver has taken the fight to the front of the grid and is locked in a championship battle, after already claiming multiple podiums and a trip to the top step this season.
