On sky q if i delete a programme I have watched, and goes into the deleted recordings. So I record a new programme on sky q, is that the way of freeing up space on my sky q, yes that true or false

True. When you delete a program you have watched on Sky Q, it goes into the deleted recordings section. By permanently deleting that recording, you free up space on your Sky Q box, which allows you to record new programs without running into storage issues. Just make sure to empty the deleted recordings section if you want to free up that space completely.
