Trust me the hours will go up! I have a feeling you're at the club i used to fly at and we're only at the beginning of the gliding season! If i am right, you are at probably the 'premier' gliding site in the UK with some seriously active members who will very soon be needing a tug pilot so they can complete their 500km flights!
You'll also have 3 or 4 comps to do during the next few months and you'll be racking up the hours then, launching 120 odd gliders in just over an hour is an amaziing site and, even if that doesn't give you much time in your logbook it'll be some of the best flying you'll ever do!
I'd keep going with the SEP stuff for the moment and the CPL/IR will fall into place.
