Careless Brits have lost more than £16 billion worth of tech and gadgets in the past five years, new research has found.
Asda Money found that adults in the UK have lost an average of £329 worth of kit each, with the average Brit having £1,815 worth of tech in their home.
Some 40% of people now have two mobiles phones, a figure which rises to 45% for those aged 18 to 34. The rise has also seen a jump in the amount of thefts that have taken place, with £450 worth of tech stolen per person in the past five years.
Those in London have lost the most, at £1,107 on average, followed by the North East (£388), Scotland (£338) and the South West (£225).
Meanwhile, 16% of people don't insure their belongings through contents insurance and this rises to 23% for those aged between 18 and 34.
Of those who don't take out cover, 30% said it was because they couldn't afford to, while a quarter (24%) said they didn't think it was worth it.
Kirsty Ward, head of Asda Money, said: "We know it is all too easy to leave your phone on the bus or to have it stolen and it feels like you've lost your right arm when it happens.
"With Christmas fast approaching, kids will be demanding the hottest gadgets on the high street and so it's even more important that parents take steps to ensure these expensive items are covered inside the house and out to avoid any nasty replacement costs."
