The GB4 Championship, partnered by the BRDC, has confirmed its 2026 event calendar, retaining the popular and cost-effective seven-round, 21-race schedule across the UK’s premier circuits. In addition, plans for a maiden Winter Series have also been confirmed, with an end of year visit to Snetterton on 24/25 October for drivers considering an entry for the 2027 season. 

GB4 will again run alongside the British GT Championship, featuring at all five of the UK rounds for the country’s premier sports car series. Once more, GB4 will be the only UK single-seater category to visit the full Grand Prix layouts at Silverstone and Donington Park twice in the year, with further visits to Oulton Park, Snetterton and the Brands Hatch Grand Prix circuit. 

For the first time, the season will commence at Silverstone on 26/27 April before returning to Oulton Park on the Spring bank holiday date of May 23 & 25, which proved a hugely popular move in 2025. The first Donington visit will follow on 27/28 June ahead of the return to Silverstone on the first weekend in August. 

The annual visit to Snetterton follows on 15/16 August, with the second Donington Park visit on 5/6 September, and the season finale at Brands Hatch on 26/27 September. 

A month after the conclusion of the main event season, the first GB4 Winter Series will take place at Snetterton. Each day of the event will feature a single qualifying session and two races, with each day also running under a different permit, allowing teams to trial multiple drivers in each car across the event should they wish.
