Lending money from a UK Limited Company

Are there any special considerations I should make if I am lending money from my UK Limited company to a third party? The debtor would be receiving the money to develop a property that the company will later purchase. The loan would ideally be at 0% unsecured.

As my company is not usually involved in providing any such financial services would this create any additional red tape with HMRC of Companies House? Would I be viewed as a financial services company and how would this be treated for corporation tax?

Any guidance would be well received!
