Derek Ladner, 57, from Cornwall, and his wife Dawn, 60, won with their usual numbers in the mid-week draw, sharing the 2.4 million pounds jackpot with four other tickets.
A week later, he found a second identical ticket in his wallet and realized he had absent-mindedly entered twice.
Their double-share of the jackpot is worth just under a million pounds.
The pair have handed in their notice at work and are taking a break to decide how to spend their windfall.
"It's beginning to sink in," Ladner told a news conference. "We are going on holiday first...and then think about what we are going to do for the rest of our lives."
