Various factors need to be considered to provide appropriate advice. My recommendation, regardless of your circumstances, is for you to contact the admission department of your academic institution of interest. With regards to receive further recommendations on this platform, I would advise you to provide more background information such as your age, professional experience and grade received for your HNC in Business, and if you have completed GCSE and A-Levels. This will make the provision of advice easier, but regardless I do recommend you to contact the university directly, especially considering that some do offer 'Pathway/Access to Law' or 'LLB Law with foundation year' courses.
