Which certificate I should add for claiming english points

[shieldguy]

I am already on HSMP and now applying for extention under Tier 1 on the place where I need to claim points of english language I have the option to select that I had already proved english language points in my prevous application (i.e. HSMP application)
but to be on safe side should I add Naric approval certificate of my four year bachelors degree and also IELTS letter with band 6 which will be expiring on 28 of july 2009

Or I should not add any of these documents?

Thanks

If your education or qualification is listed in the online points based calculator, then you don't need to provide any documents for english language. Just, mention it on the cover letter.

But to be on the safe side should I do it or it could sow down processing time ?
