The winning player matched numbers 23, 25, 32, 37, 42 and Lucky Stars 01 and 11 to make them the sole winner of Tuesday”s draw.
It is yet another success for UK EuroMillions players, after a British ticket holder won a £24million jackpot earlier this month.
There is no information on whether the prize was won individually or as part of a syndicate, or where the ticket was purchased.
A National Lottery spokesman said: “This year is certainly turning out to be a lucky one for UK National Lottery players.
“Last year saw an unprecedented nine UK EuroMillions jackpot winners and this year we have already had two massive wins here and it”s only February.”
EuroMillions is played in a total of nine countries: Austria, Belgium, France, Ireland, Luxembourg, Portugal, Spain, Switzerland, and the United Kingdom.
Draws take place on Tuesday and Friday evenings at approximately 8.30pm GMT.
The win comes hours after Peterborough couple Gerry, 63, and Lisa Canning, 48, were revealed as the winners of a £32.5million Lotto draw.
The couple took a week to claim their prize after waiting for the decorators to finish renovating their house.
Mrs Canning, a retired teacher, said: “I know it sounds mad but we had a guy in to paint the whole house. We”d been planning it for ages and had packed everything into boxes.
“We just thought it would be easier to wait, although it did mean that Gerry had to carry round the winning ticket in his wallet all week. It was very nerve-wracking.”
The couple”s win places them second in the Lotto rich list, just behind last month”s biggest ever Lotto winners, David and Carol Martin, and one other anonymous ticket holder, who both scooped a £33,035,323 jackpot prize each in the draw on 9 January.
Gerry and Lisa are among the 88 ticket-holders who have scooped £1 million or more since October.
This includes jackpot winners and the guaranteed millionaires made by Lotto Millionaire Raffle in each and every draw.
