The race was originally organised by Britcar. The 2009 race was shortened to 500 miles due to the recession. In the 2010 race it was the first time they used the new Arena Circuit, previously they used the Bridge Grand Prix Circuit. The 2013 edition was shortened to 1000 km. For 2015 the race was called the Dunlop 24hr at Silverstone for sponsorship reasons.
On October 2 2015 Creventic, the promoter and organiser of the 24H Series and the Touring Car Endurance Series, announced they would organise the Silverstone 24-Hour race in 2016. It was the third round of the 2016 24H Series season and the first round of the 2016 Touring Car Endurance Series season. Every round of the 24H Series can be entered with a GT car, but this race is only open to non-GT cars.
