Yes, you can get details from the website, you need to pay a fee on-line. You can find out the names and addresses of all Directors of a company, and also what other companies they are a Director of too. As well as all the companies they have been a Director of in the past.
I have access to all that stuff as well. You have to be a bit careful because it's amazing how many Directors have the same names. As such, if possible it's best to use the date of birth when cross-referencing.
