Quick question about deed polls

[dariaismyname.livejournal.com]

So I'm doing a DIY deed poll to change my birthname. Under UK law you can just print the form out with the right names in the right places and send it out to whoever it concerns. I was wondering if anyone knew the deal with changing title? I know that a deed poll doesnt count as a change of gender, but all the sites that will charge you for these same printouts say that you can totally change your title, and they will add £4 on to your bill. Is it just a case of putting the titles in with the full names?
