Hatallas, get in touch with your nearest college or university. Many traditional universities have learning departments/schools dedicated to 'life-long learning' (adult learners) where you can earn a degree on a part-time basis.
Some institutions offer part-time degree courses where you can also be awarded interim qualifications along the way like a CertHE or DipHE in your chosen subject area. These are stand-alone qualifications in their own right and can help with career progression.
