The UK’s top town for unfaithful partners has been revealed.
According to data from IllicitEncounters.com, the UK’s leading extramarital dating site, people living in Ascot are most likely to cheat.
The Berkshire town, best known for the prestigious horse racing events, might be an unlikely hotspot for affairs. However, the annual Infidelity Index reveals that 6.72 per cent of Ascot’s population had affairs in 2025.
Wilmslow in Cheshire and Alness in the Highlands also ranked highly for adultery.
In contrast, the most faithful town was Clacton-on-Sea in Essex.
Harlow in Essex also had a low proportion of cheaters, as well as Hartlepool in County Durham.

What else does the report reveal?
The report also shows a 6 per cent rise in affairs nationwide since January, continuing a two-decade trend of increasing extramarital activity.
Jessica Leoni, sex and relationships expert for IllicitEncounters.com, said: “Affluent commuter towns like Ascot and Wilmslow are classic affair hotspots.”
However, she added: “It seems residents of the seaside town are remaining remarkably faithful.
“These places are hubs for high-flying careers, long commutes, and significant stress – affairs can become a form of release or a way to reclaim your identity, so it’s no surprise these places are buzzing with passion.
“Perhaps the political drama on their doorstep is providing enough excitement for everyone, leaving no reason to stray from their partners.”
Illicit Encounters has previously speculated that the three main reasons that people cheat are waning intimacy, emotional disconnect and low self-esteem.
