Three drivers have received post-race penalties following the Formula 3 Feature Race at Silverstone.

Brad Benavides has been assigned a five-second time penalty that has been added to his race time. Race stewards found that after reviewing evidence the driver left the circuit four times without justifiable reason. The time penalty drops Benavides from 18th to 20th in the final classification.

Kush Maini has also received a five-second time penalty for leaving the track two times at Turn 9 and two times at Turn 15, without justifiable cause. The penalty drops the MP Motorsport driver from 20th to 22nd.

Grégoire Saucy has been handed a 10-second time penalty added to his race time. Race stewards found that the ART Grand Prix driver was wholly at fault for the incident between himself and Trident's Roman Stanek at Turn 6. The penalty drops the Swiss driver from 23rd to 25th.
