You need to speak to a decent accountant, but my suspicion is that you can’t do what you are proposing for some relatively simple reasons:
- you open a FT account in your name (not that of the Ltd company) and therefore any assets you purchase belong to you
- you can’t use the assets of a Ltd company for your own personal benefit exactly to stop you doing this sort of thing ie that they are not your assets (they are the Ltd company’s, which even though you own it the company still is a separate legal entity), plus also to stop people avoiding paying tax on dividends or income.
You might be able to view it as a loan to a director, but I suspect any reputable accountant would tell you that was only possible in certain circumstances.
