The National Lottery has created more than 7,700 millionaires since its first draw in November 1994. But here’s the uncomfortable truth: a meaningful minority of them end up worse off than before the win. Some go bankrupt. Others burn through the lot in under a decade. The often-cited claim that 70% of winners go broke has been debunked, but the cases that do go wrong tend to follow the same patterns.
High-profile cases of winners going broke get a lot of attention, and research does show that lottery winners file for bankruptcy at roughly double the rate of the general population. But a Camelot-commissioned survey found that 82% of UK millionaire winners reported being as well-off or better-off than before their win.
That said, the mistakes that lead to financial ruin are surprisingly consistent. The same traps come up again and again, from impulse spending to bad investments to lending money they’ll never see back. Let’s look at the most common ones and what winners should actually do to protect a sudden windfall.
The Spending Spree That Never Stops
The first thing most big winners do is spend. And that’s totally understandable. A new car, a holiday, maybe paying off the mortgage. The problem is when the spending doesn’t slow down.
A £5 million win sounds like an endless pot of money, but luxury cars, designer clothes and five-star holidays add up fast. Without a budget or any structure around spending, it’s easy to get through £500,000 in the first year alone. And once the lifestyle inflates, it’s very hard to bring it back down.
Many winners also underestimate how quickly money disappears when there’s no income replacing it. The lump sum feels huge, but if it’s funding a lifestyle that costs £200,000 a year and earning nothing, the maths doesn’t take long to go wrong.
Property Deals That Go South
A common next step is property. Winners often buy multiple homes, invest in developments or get into buy-to-let without any real experience. Property can be a solid long-term asset, but only if you know what you’re doing.
Overpaying for a dream home is one issue. Getting into property development with no background is another. There are plenty of stories of winners sinking six figures into renovation projects that stall, or buying rental properties in areas where demand doesn’t hold up. Without proper due diligence, property becomes a way to lose large sums very quickly.
Lending to Friends and Family
This one comes up in almost every case study of lottery winners who’ve gone broke. Friends, family, distant relatives and old acquaintances all come asking for money. And it’s incredibly hard to say no when you’ve just come into millions.
The trouble is, informal loans rarely get paid back. Gifts create expectations for more. And relationships fall apart when the money runs out or when people feel they didn’t get their fair share. Financial advisers who work with sudden-wealth clients almost always recommend setting clear boundaries early, before the requests start spiralling.
No Professional Advice (or the Wrong Kind)
This is probably the biggest mistake of all. Many winners either don’t seek financial advice or turn to people who aren’t qualified to manage that kind of wealth. A local accountant who handles small-business tax returns isn’t equipped to build a long-term plan for a multi-million-pound windfall.
What winners need is a structured plan that covers income generation, tax efficiency and long-term capital preservation. One thing many winners don’t realise is that while the winnings themselves are completely tax-free in the UK, any income they generate afterwards, whether from savings interest, investments or rental property, will be taxed in the normal way.
For someone sitting on a multi-million-pound windfall, an investment management service in the UK with experience managing large portfolios will be better placed to build a long-term plan than a generalist adviser. That kind of structure is what separates the winners who stay wealthy from the ones who don’t.
The National Lottery’s own winner support team also offers guidance to big winners, including sessions with financial advisers. It’s free and available from the moment you claim your prize. But it’s a starting point, not a full plan, and most experts agree that independent advice tailored to your specific situation will be what protects the money long-term.
Getting the right advice early, ideally before making any major purchases, can make the difference between a windfall that lasts a lifetime and one that’s gone in five years.
A Windfall Won’t Last Without a Plan
Winning the lottery is a life-changing event, but the change can go in either direction. The winners who come out well tend to be the ones who pause, get proper advice and treat the money as something to manage rather than something to spend. The ones who don’t often end up as cautionary tales.
The bottom line is simple: sudden wealth creates problems that most people have never had to deal with before. And without the right guidance, those problems will eat through the money faster than anyone expects.
Note: Markets move, and so does the value of your investments. Income from them can also fluctuate. There’s a possibility you’ll get back less than you put in, and past performance isn’t a reliable measure of what lies ahead.
