Aitken remained at Campos for 2020, partnering Guilherme Samaia. Aitken took a double-podium finish at the second Silverstone round, finishing third in both the feature race and sprint race. He was involved in a high-speed collision with Luca Ghiotto on lap seven of the sprint race at Sochi. Both drivers were uninjured, but damage to the barriers caused the race to be red-flagged and not restarted.[12] Aitken missed the final round at the Bahrain to race in Formula One, and was replaced by Ralph Boschung. Aitken finished 14th in the standings, scoring all of Campos' 48 points.

Formula One career
Renault test driver (2016–2019)
In February 2016, Aitken was one of four drivers confirmed to join the young driver program of Renault F1.[15] In September 2017, Aitken sampled Formula One machinery for the first time, testing the Lotus E20 at Jerez.[16] In February 2018, Aitken was appointed as third and reserve driver for Renault.[17][18] That year, he tested the Renault R.S.18 at the Circuit de Barcelona-Catalunya during the young drivers' test.[19] Another test came at Suzuka where once again he drove the R.S.18.[20] Aitken continued as test driver for Renault in 2019,[21] and once again took part in the 2019 young drivers' test at Barcelona.[22] In February 2020, Aitken left Renault.[23]
Aitken made his Formula One debut as a race driver with Williams at the 2020 Sakhir Grand Prix as a replacement for George Russell, who was promoted to Mercedes following Lewis Hamilton's positive coronavirus test.[26] Aitken stated before the event he had been "ready since Melbourne [March]" for such an opportunity.[27] He chose to race with the car number 89, in reference to a number he previously used in karting.[26] He qualified for the race in 18th place, within a tenth of a second of teammate and regular driver Nicholas Latifi.[28][29] On lap 61 of 87, 15th-placed Aitken spun at the final corner, colliding with a barrier and breaking off his front wing. He returned to the pits for a replacement and was able to continue the race, eventually finishing 16th. He later remarked that he had mixed feelings about the race, stating "I think we were doing a really good job up until my little incident. I can only apologise to the whole team", but that there were "a lot of positives to take from the weekend".[30]
Aitken performed Thursday media duties with Williams ahead of the next race in Abu Dhabi but ultimately did not drive the car, as Russell returned to the team prior to FP1 when Hamilton was passed fit to return to Mercedes.[31]
In March 2021, Williams announced that Aitken would continue to be their reserve driver for the 2021 season.[32] He took part in FP1 at the Abu Dhabi Grand Prix, replacing Russell for the session.[33]
Aitken retained his reserve driver role with Williams for the 2022 season.[34] He did not partake in any practice sessions that year, and at the start of 2023, he was announced that he would split with Williams, in order to focus on his sportscar career.[35]

He crashed into the barrier after Raidillon, bounced back onto the track and came to a stop before being hit from behind by another driver which caused two further cars to become entangled in the accident. Aitken was taken to hospital where he stayed overnight.[37] His injuries were described as non life-threatening though serious and it was later revealed that he had sustained "a broken collarbone, a fractured vertebra ... and a very small lung contusion".[38][39]
