With a perfect match of winning numbers the ticket holder was immediately launched into the exclusive club of the UK's ultra-rich.
That, according to those who assist big money winners, is a "daunting" experience that leaves most of them in shock.
They say it can take a couple of years for these millionaires to find the rhythm of their new-found riches.
Understanding the reaction and requirements of these lottery winners can tell us a lot about coping with sudden wealth, from inheritance to rapid business success.
Anyone who has a lottery win of more than £50,000 receives a visit from Andy Carter or one of his team of five winners' advisers.
The 41-year-old, employed by lottery operator Camelot, checks the ticket-holder's identity and other paperwork then oversees the bank transfer of the prize. No longer is it written on a cheque and, unlike some overseas lotteries, the money is paid immediately in one lump sum rather than in instalments.
After nine years in the role, Mr Carter has seen the full range of reactions and spending plans, from plastic surgery to buying a fireworks company.
"By the time I get there [the day after the winners' call], some have already arranged a viewing on a house," he says.
"But the perception is that winners go out and buy a fast car. They don't. They are in shock. They realise they need some help."
He is not allowed to give any financial advice, but he does suggest that winners take a holiday before the spending starts.
He says a tiny minority of winners either go out and blow the cash, or do the opposite and put the money in a bank account and leave it untouched.
"A win does not change people's values around money, it exaggerates them," he says.
Most want to pay off a mortgage, and find the lack of ceremony when it is done to be strange. Nearly all want to look after their families' finances.
He suggests that people take their time and do not promise anything straight away.
