According to multiple Reddit threads, Sex Education is set in the present day, but the show intentionally includes elements from different time periods to create a timeless feel. For example, the fashion and transport are from the 70s, while the technology is from the present day. Some viewers have also noted that the show includes references to the 2000s and 2010s. However, the show is not set in the 1980s, as some viewers have speculated. Overall, the shows setting is intentionally ambiguous and not tied to a specific year or time period.
