It wasn't until the end of hostilities in World War Two that Brands Hatch became serious about its motorsport. Used during the war as a military vehicle park, the circuit was subject to numerous bombing raids and needed much work to get it back up to scratch.

In January 2020, work to improve safety in the final part of the lap began, centred around creating enlarged gravel traps at the Clearways and Clark Curve section of the circuit. Armco barriers and debris fencing will be further away from the circuit, leaving the gravel trap significantly extended in order to increase its effectiveness. Spectators can still watch around the outside of the final section of the lap, with a raised viewing area constructed to improve the view.
