Not so. Thatcher called a snap election in '83 after the Falklands War. Interestingly, she actually only gave 4 weeks notice of the election date.
Depending on your definition of "snap election", it could be said that Blair's second election victory in 2001, which was a year short of a full term, might fall into that category.
It's not my definition - it's being reported now as being the first snap election since 1974:
"The last snap election was in October 1974. It came just eight months after the previous vote which had resulted in a hung parliament, and gave the Labour Party a slim majority of 3 seats." (Express)
1983 and 2001 don't seem to be counted as snap elections, although obviously they were "early."
