Form W-8BEN-E for UK limited companies

Bit of a dry blog today, if you want entertainment you should look elsewhere. But I was trying to help a few people on Twitter with this earlier today, and thought it would be useful to have somewhere to point to.
Really great advice - the only online. However, my US customer came back to me and said that we cannot "ignore section 5 (chapter 4 status)“ I’ve no idea which applies to my UK Ltd. company? Any ideas
