Nearly a fifth of British adults have admitted to damaging their ex or current partner's belongings to the tune of £121 per person by committing an act of revenge.
New research from comparison website gocompare.com found 7% of people had intentionally damaged or broken their partner's items, while 10% admitted they did it to a former partner's belongings too.
Of those who owned-up, 42% said they did so to seek revenge on their partner or ex, more than a third (32%) said it was due to their loved one's irritating behaviour, while 17% said they broke the items as their partner or ex constantly used it.
Some 6% even admitted they damaged an item so they could claim on their insurance.
According to the findings, women are almost twice as likely to intentionally damage their partner's goods, (12% of women, compared with 7% of men).
Unsurprisingly, technology items were the most damaged. A quarter (25%) said they had damaged a laptop or computer, followed by a mobile (22%), video games console (16%) and television (15%).
In total, the cost of the damaged caused by this revenge vandalism comes to a £1 billion.
Ben Wilson, gocompare.com's home insurance spokesperson, said: "Many people don't know that malicious damage is something you may be able to claim for - but if you go down this route, it means reporting the damage to the police in order to get a crime reference number. If you're reporting an ex, this is a sure-fire way to ensure they stay an ex."
He added: "With one in 20 saying they intentionally damaged products as part of an insurance claim, it appears to be a relatively common practice and of course, one that we'd advise against. It's fraud, plain and simple, and pushes up premiums for everyone."
