The championship featured a mix of professional motor racing teams and privately funded drivers, and also featured the 2-litre 230-bhp Tatuus-Cosworth single seat race car in the main series.
The season commenced at Oulton Park on 1 August and ended on 8 November at Silverstone Circuit, after seven triple and quadruple header events for a total of twenty-four races.

Race two, which reversed the order of the race one finishers, providing they set a lap time within 103% of the fastest driver, awarded extra points for positions gained from the drivers' respective starting positions.
