The GB4 Championship has unveiled its provisional 2027 calendar, retaining its established seven-round, 21-race format while reshuffling the order of several events.
Snetterton will open the championship on 10-11 April before Donington Park hosts the season finale on 16-17 October. Silverstone, Oulton Park and Brands Hatch also remain on the schedule, while a separate Snetterton Autumn Trophy will return one month after the main championship concludes.
The announcement maintains GB4’s exclusively British calendar and follows the same fundamental structure outlined in Pit Debrief’s guide to the 2026 GB4 Championship. However, the positioning of several circuits changes considerably, most notably with Snetterton moving from the middle of the season to the opening weekend and Donington replacing Brands Hatch as the title decider.
Snetterton moves from August to season opener
The 2027 championship will begin at Snetterton on 10-11 April, giving the Norfolk circuit the opening round after it occupied the fifth position on the 2026 GB4 calendar.
That represents one of the largest changes between the two schedules. In 2026, Silverstone opened the campaign on 25-26 April before Oulton Park and Donington followed. Snetterton did not appear until 15-16 August, when the circuit hosted the fifth of seven rounds.
The circuit produced an important championship swing this season. Alex O’Grady won both principal races, including Race 1 after Fred Green retired while leading, before Josh McLean won the series’ 100th race in the reverse-grid finale. O’Grady subsequently left the weekend with a 70-point championship advantage.
In 2027, teams and drivers will instead face the technical 300 layout immediately, making Snetterton the first opportunity to establish an early championship advantage.
Silverstone follows in May
GB4 will make the first of two visits to the Silverstone Grand Prix circuit on 8-9 May, four weeks after the Snetterton opener.
The meeting will run as part of a MotorSport Vision Racing event rather than alongside British GT. Silverstone also appeared twice on the 2026 calendar, but its first event opened the season in late April before the championship returned on 1-2 August.
Its second 2027 appearance retains an August slot, meaning Silverstone remains the only venue besides Donington Park to host two rounds during the main championship.
The two Silverstone events continue to give young drivers extensive experience on the Formula 1 Grand Prix layout. The circuit has also regularly produced large GB4 fields, with the 2026 season opener featuring a record 29-car entry.
Oulton Park retains Spring Bank Holiday position
Oulton Park follows on 29 and 31 May, maintaining its traditional Spring Bank Holiday slot.
The championship will again support British GT at the Cheshire venue, with the weekend spanning Saturday and Monday rather than the conventional Saturday-Sunday format.
Oulton therefore remains the third round of the season, although it moves one position later than in 2026. This year, the circuit hosted Round 2 on 23-25 May after the Silverstone opener.
The layout continues to provide a distinctly different challenge from Snetterton and Silverstone. Its narrower track, significant elevation changes and limited overtaking opportunities place additional emphasis on Qualifying, something that remains particularly important under GB4’s format because each driver’s two quickest laps establish the grids for the weekend’s opening two races.
Donington moves into July
Donington Park will host its first 2027 GB4 event on 17-18 July, moving several weeks later than its equivalent meeting this season.
The Leicestershire circuit hosted Round 3 on 27-28 June in 2026. Next year’s first visit instead becomes Round 4, positioning Donington at the midpoint of the championship.
Like the first Silverstone meeting, the July Donington event will form part of an MSVR weekend rather than the British GT package.
Donington has played a major role in the 2026 campaign, hosting two rounds. O’Grady took a double pole at the first event, while the second visit in September saw Green return to winning form and Yani Stevenheydens make an immediate impact during his one-off appearance with Elite Motorsport.
The circuit again receives two dates in 2027, although its second meeting takes on greater significance by becoming the championship finale.
Second Silverstone visit begins title run-in
The championship returns to Silverstone on 7-8 August for Round 5, with the event again running alongside British GT.
That weekend begins the final three-round stretch of the season, with Silverstone followed by Brands Hatch and Donington Park.
Its August position remains almost identical to 2026, when the second Silverstone meeting took place on 1-2 August. Therefore, teams will continue to encounter the Grand Prix circuit during the second half of the championship after already racing there earlier in the year.
The repeated visit gives teams an unusual opportunity to return to a circuit with current-season race data, although changing conditions between May and August could still require significantly different setup approaches.
Brands Hatch moves away from finale
Brands Hatch remains on the calendar for 11-12 September but loses its position as the championship finale.
The Kent circuit concludes the 2026 season on 26-27 September, with O’Grady and Green heading there as the leading Drivers’ Championship contenders. In 2027, Brands Hatch moves forward one position to become Round 6.
GB4 will again use the full Grand Prix layout, which recently hosted the championship’s pre-finale test. Thomas Ingram Hill led that running ahead of Green and O’Grady, with the leading championship contenders closely matched before the decisive 2026 weekend.
Despite losing the finale, Brands Hatch remains part of the British GT support package and will form the penultimate championship event before the teams return to Donington approximately five weeks later.
Donington Park becomes 2027 title decider
The main championship concludes at Donington Park on 16-17 October, marking a significant change from the 2026 schedule.
This season’s second Donington event took place on 5-6 September as the penultimate round, before Brands Hatch assumed finale duties. In 2027, those roles effectively reverse, although the Donington event also moves more than a month later in the year.
GB4 has described the October meeting as the Donington Park “Decider”, with the championship again joining the British GT package.
The switch also extends the main season considerably later into the year. The 2026 championship ends on 27 September, whereas the 2027 title battle will continue until 17 October.
Drivers will consequently face potentially colder and less predictable autumn conditions during the decisive weekend, adding another variable to the final three races.
Five rounds remain on British GT support package
GB4 will continue supporting the British GT Championship at all five of its UK rounds in 2027.
Those events are scheduled for Snetterton, Oulton Park, the second Silverstone meeting, Brands Hatch and the Donington finale. The May Silverstone and July Donington events will instead run on MSVR programmes.
That arrangement preserves one of GB4’s principal exposure opportunities. British GT weekends provide larger trackside audiences and place the championship alongside GB3 and other national categories on major UK race programmes.
The championship still retains two additional standalone opportunities within the wider MSVR structure, ensuring the seven-round season continues across the same five circuits used in recent campaigns.
Autumn Trophy returns at Snetterton
Although the main Drivers’ and Teams’ Championships finish at Donington, GB4 activity will continue for another month with the return of the separate Autumn Trophy.
Snetterton will host the event on 13-14 November, bringing the championship back to the circuit where the main campaign began seven months earlier.
GB4 expects the Autumn Trophy to retain its compact format of one Qualifying session and two races on each day. That would create four races across the weekend and provide additional competitive mileage outside the main 21-race championship.
The standalone event also provides an opportunity for prospective 2028 or late-2027 entrants to gain race experience with GB4 machinery without committing to the full championship.
Its November date means Snetterton effectively bookends GB4’s wider 2027 programme, hosting both the April season opener and the final competitive event of the year.
2027 GB4 Championship provisional calendar
The official provisional 2027 GB4 calendar is:
- 10-11 April — Snetterton 300
- 8-9 May — Silverstone GP
- 29 & 31 May — Oulton Park International
- 17-18 July — Donington Park GP
- 7-8 August — Silverstone GP
- 11-12 September — Brands Hatch GP
- 16-17 October — Donington Park GP
2027 GB4 Snetterton Autumn Trophy
- 13-14 November — Snetterton 300
All dates remain provisional and subject to change.
Familiar circuits but a revised championship flow
GB4 therefore retains the same seven-round format and the same five principal circuits in 2027, but the revised sequence substantially changes how the season develops.
Snetterton moves from Round 5 to the opener, while Silverstone loses its season-opening position and instead hosts Rounds 2 and 5. Oulton Park shifts from second to third, the opening Donington visit moves from June into July, and Brands Hatch changes from the finale to the penultimate round.
Most significantly, Donington becomes the championship decider and extends the main season into mid-October. The returning Autumn Trophy then keeps GB4 competition running until the middle of November.
The fundamental format remains familiar, but the altered order creates a different rhythm for 2027 as Snetterton opens and closes the wider GB4 year while Donington assumes responsibility for crowning the next Drivers’ and Teams’ Champions.
