Ginetta GT4 Supercup
In 2020, Burton moved up to the Ginetta GT4 Supercup, signing with Century Motorsport for the full season. He would immediately find success, qualifying on pole for the opening race of the season at Donington Park. During race one, Burton dropped back to third behind Will Burns and Tom Hibbert respectively, where he remained until the finish. He would finish on the podium again in race two, this time in second. Burton would finish one step higher in race three and break through to get his maiden win of the season. Following the opening round at Donington, a championship battle between Burton, Burns, and Hibbert was starting to form, with all three drivers finishing on the podium in all three races at Donington. Burton would demonstrate consistency once again in the next round at the Brands Hatch GP Circuit, finishing in second in all three races. Hibbert won races one and two, demoting Burton to third in the championship. Burton would dominate the next two races at Oulton Park, qualifying on pole for race two and winning both races. Burns and Hibbert would have mixed weekends by comparison, with both getting onto the podium in race one, but finishing eight and fourth in race two respectively. Burton would get another pole in race one at Thruxton, but would retire in the race and lose points to Burns and Hibbert. In the next four races at Thruxton and Croft, Burton finished in third in every race. Burns extended his gap to Burton with two wins and a second place at Croft, while Burton only managed a ninth place finish in race three at Croft. The penultimate round at Snetterton saw mixed results for Burton, with a retirement in race one, but a third and a win in races two and three. Going into the final two races of the season at Brands Hatch, Burton was 43 points behind Burns in first. In race one, Burton finished on the podium in second, while Burns finished in fourth. Burton was able to win race two with Burns finishing behind in second. However, this was not enough for Burton to win the championship, and thus finished second to Burns.

Following his maiden championship in British GT, Burton switched over to the Porsche Carrera Cup Great Britain for 2022, staying with Century Motorsport to compete in the Pro category. He would have a up and down first weekend at Donington Park, qualifying on pole for both races, but finishing fourth in race one, and retiring in race two. The next two rounds at Brands Hatch and Oulton Park were similar for Burton, with two points finishes in the Brands Hatch races, but no points in the Oulton races. He would qualify on pole for the next race at Knockhill, and would go on to convert it into his maiden win in the championship. For the rest of the season, Burton would score points in all of the remaining races, finish on the podium four times, as well as win a second race at Thruxton. He would finish fourth in the championship.
2023
For the 2023 season, Burton rejoined Century Motorsport for a partial schedule as he would be competing full-time in the 2023 Porsche Supercup. In the first round at Donington Park, Burton would finish on the podium in both races. However, the next round at Brands Hatch was not successful for Burton, with a non-points finish in eleventh for race one, and a retirement in race two. Mid-way through the season, Burton switched teams to Joe Tandy Racing, and would drive for them starting at the Knockhill round. He would immediately find success, qualifying on pole position for race one and going on to win the race. A retirement in race two would conclude a mixed weekend.
