I agree with Smartkhan that you should get a NARIC letter if you are worried, secondly I don't think you have read the thread I provided properly. If you open the PDF which was sent to one of the guys who asked same question to UKBA (Link:

6. How do I show that my qualification is deemed by UK NARIC to be the recognised standard?
UK NARIC regularly update the online points based calculator (which is on our website) with information about various degrees.
If you obtained a degree overseas and were awarded ten points for English language skill, you can submit evidence from the online points calculator, together with the original degree certificate, to demonstrate that you can satisfy the English language element of the Knowledge of Language and Life in the UK (KOLL) requirement.
Alternatively, you can obtain confirmation from UK NARIC that your qualification was taught or researched in English by requesting an English Language Assessment (ELA). Details of how to contact UK NARIC can be found at:

secondly am also in the same boat as you are mate and will be applying on 17th Feb i.e. next week Monday!! So you can wait for the result I post and see what the outcome is. Lastly I am not submitting a NARIC letter as I don't think it is even required when PBS Calc is recognizing the degree and awarding points for English.
Kind Regards
