Revealed: The cheating capital of the UK (2025)

A new poll has revealed the UK city where Britons commit the highest levels of adultery.

Britons from Nottingham are the most likely to cheat on their partner, with a staggering 41 per cent of participants admitting to have done their significant other dirty.

Robin Hood's hometown isn't the only Midlands location topping the chart, with Leicester claiming the second spot due to the 40 per cent of participants who admitted to cheating.

Leeds, Plymouth, and Norwich didn't fall far behind with them having 38 per cent reporting infidelities.

On the flipside, the study of 2,000 participants, conducted in conjunction with the launch of new Netflix show, Cheat: Unfinished Business, also revealed the locations where partners turn their backs on cheating, and it's good news for those from Sunderland.

The port city is home to some of the most faithful partners, with 83 per cent of participants remaining loyal to their partners.

Elsewhere, Glasgow and Liverpool proved to be trustworthy locations, respectively homing 76 per cent and 75 per cent who have never cheated.

The poll also explored the common reasons why people choose to cheat on their partners, with boredom, falling out of love, and being drunk, all listed.

Relationship expert Paul C. Brunson told the Mirror, 'These findings expose the complicated, and often painful, reality of modern relationships.

'They reveal a striking disconnect between behaviour and accountability, with a significant number of people admitting to infidelity without facing consequences.

'But this research goes beyond shock value. It underscores the deep emotional toll of betrayal and the fragile process of rebuilding trust.'

It comes after a former detective and body language expert revealed the five red flags that may mean your partner is cheating.

Darren Stanton, from Nottingham, said that in a relationship couples develop an 'almost telepathic connection' and 'the slightest change the slightest deviation from the norm is noticeable'.

Speaking to Techopedia, he revealed how changes in behaviour and routine are among the signs that could indicate infidelity.

He added that January is a peak month for couples to split - with Google searches for 'how to tell if your partner is cheating' spiking by 45 per cent.

According to Darren, the number one red flag that could signify an unfaithful spouse is changes in patterns of behaviour.

He said, 'One or two changes in behaviour are not really significant, we are looking for six or seven consistent changes to their normal actions.'

The expert also highlighted a partner's sudden change in how and when they use their mobile phones as another key sign.

Darren said, 'Phones are such a big part of our lives and a reluctance to leave your mobile phone out unattended or allowing your partner to look at your phone is a flag.'

Another red flag is when someone places their phone facing down on a table or surface because this could signify an attempt to conceal an innocuous text or call popping up.

If an individual is having an affair, it's crucial to acknowledge they are managing two different lives, meaning more conscious effort goes into juggling routines.

Darren added, 'You have to have a very good memory because you have two lives on the go.'

If your partner makes significant changes to regular activities and how you both spend time together, it might indicate they are having to keep up appearances elsewhere.

Darren advised to look for any reluctance in what used to be the norm, such as date nights, anniversaries, or family events.

If your partner is someone who consistently posts on Instagram or TikTok and suddenly stops, this could indicate they want to draw less attention to themselves and become 'invisible.'

Darren warned changes on social media can be significant, 'They want to seem out of the loop to reduce their chance of being caught out.'

The expert highlighted a partner's sudden changes in appearance as a red flag because it could signify a need to impress their lover, an attempt to live up to their ideals or expectations, or simply because of a newfound sense of confidence.

Darren added, 'If someone is suddenly buying clothes and making a lot more effort in their appearance, wearing more aftershave and taking more pride in their appearance it can be a red flag.'
