Don't know enough about this area to properly advise but as a shareholder you certainly have the right to inspect the books by appointment though not necessarily access to confidential information such as payroll. I would think you ought to be informed before a voluntary application wind up was submitted but I doubt you could actually prevent it with a holding of less than 25% unless you combined with someone else to take the percentage above that.
Might be worth contacting Companies House who may be able to offer some advice on this.
