The series is run to the FIA's Formula 4 regulations, and is administered by Motorsport UK.

With Motorsport UK taking over the organization of the championship for years 2022–24, as Ford concluded their involvement, the championship will switch to a Tatuus chassis and Abarth as the engines supplier.

Fifteen-year-olds are eligible to compete in the series, after the MSA lowered the age limit for single-seater championships.

[4] Hankook was the sole tyre supplier, with the cars running on the same compound and construction rubber as used in Formula Three.

The engine control unit was an F88GDI4 from Life Racing which featured integrated paddle shift control, GPS track mapping and also functions as the complete data acquisition system.
