Is there a free way of finding out a companies profits / turnover?

Is there a free way of finding a companies profits / turnover?

I've not had a pay rise for the last 2 years because of the 'economic climate' and just want to see if my boss is telling the truth ;-)

Went onto the company house website and paid a few quid to download a few of the documents but cant seem to find how much profit etc my company has made over the last 3 years? By the way its only a Limited company.

Thanks for any help

I'm sure alot more people would like to know this info as well for where they work :-)
