Do you need planning permission for a garage conversion?

We want to turn our integral garage into a living room but I'm not sure if we need permission first. It's a detached house in a standard residential street.

"Hi if it’s going to be a space that you either live in or sleep in then yes
If your adding a toilet yes
Other than that most times you don’t
Best to check with your local building control office to be safe
Can be costly if you do the work and planing is required"
