I don't understand your response but the situation is simple. If the business continues to exist, but is simply transferred to another owner, you have 'TUPE' rights, which are explained here:

However, as I read your post, it seems more likely that your jobs will simply cease to exist. In which case your employer must pay you (as an absolute minimum) Statutory Redundancy Pay. Information about that (including how to calculate the relevant amounts) is in my first link.
