Depends how pedantic the lecturer is. Some rigidly stick by writing guidelines, some don't give a toss. Any penalty will depend on the university/department, but I doubt it will be serious.
Taking into account that you will have been told from Day #1 to double-space, then yes; you'll be penalised pretty heavily for not double-spacing, even as much a slowing 20% of your marks for the essay.
Suck it up, you'd have been told (if you attended the first lectures) to double-space
