There are literally hundreds of options for online/distance learning courses from UK universities - just google distance learning or look on the UCAS website. Quality obviously varies from institution to institutions and course to course but you can usually find plenty of reviews online to help you make an informed decision. Ideally you should look for a course that has the same or very similar assessment criteria as the regular degree offered by that uni. It's also sometimes possible to do online top-up courses on one of those degrees you started but didn't finish. They are shorter, less intense and obviously cost less in order for you to gain your degree.
