UK general elections are meant for people to vote and pick their local Member of Parliament and not the Prime Minister of the country. But the official House of Commons Library records show that 12 of the 19 British prime ministers since World War II actually took office midway through a term after the previous leader quit.
This means party members and not the general public chose recent Prime Ministers like Rishi Sunak and Theresa May before any voter got a say.

Why Britain Allows Prime Ministers without General Elections?
The system works this way because the monarch simply appoints whichever politician can control a majority of votes in Parliament. As long as the winning party keeps its majority in the House of Commons it has the legal right to swap leaders whenever it wants.
