Yes, but not all universities accept OU modules and those that do will have different admission requirements (for example, some places might only require 60 credits at level 1, whereas others want 120 credits at level 1). You should ideally research what degree you want to do , where you want to do it and whether or not that university accepts OU credits before you sign up for an OU course, otherwise you might be disappointed.
What do you want to study and where were you thinking of going? I can tell you that I applied to UCL, Edinburgh, Royal Holloway and Aberdeen with OU credits and they all accepted me.
