Malvolio is correct. Although what is called an IR35 friendly contract (and by that, we mean that is contains clauses relating to substitution, no MOO, fixed deliverables, etc) is very useful and gets you off to a good start, if it comes to a showdown with HMCR it is only the real working arrangements that matter. If your boss says "he comes in every day, works 9 to 5, and does whatever I tell him to", you are sunk, no matter how whizzy your contract is.
If your contract is IR35 friendly and matches your working practices, a confirmation of arrangements letter from the client has been found to be useful by some. Some clients, of course, won't help you out with this anyway.
