I'll check what we've got on. Might be fully booked till X as now. Mikey, The first GUE course that most people do is Fundamentals, this is a course for already qualified divers and it builds on the core skills like buoyancy and trim with some other skills/procedures thrown in as well (Rec1 is for brand new people that can't dive yet, think of it like PADI OW, AOW, Rescue and Nitrox all in one). It does not change the depth that you can dive to but it will give you a nitrox certification. Findamentals is all about improving your diving skills, whether that's to take the next step into technical diving/cave diving or just to make you a better diver doing the dives you are currently doing. There is PLENTY of value in doing a course like Fundamentals even if you are diving a single.
