early extension (1 year early)

[tier1-immigrant]

I got my 1st extension last year and my current visa expires 2015.
I will have to go for one more extension in 2015 as I came to UK a year later after I got Tier1 for the first time.

I need to earn 50K for my extension, which is very difficult in the current situations. I am currently contracting through my ltd company. And I am not sure whether I will still be contracting during the period 2014-2015 during which period I need to earn 50K in order for me to secure an extension in 2015.

Since I am in contract now and suppose I continue earning through my current contract for 12 months between 2013 and 2014, can I apply for extension in 2014 instead of 2015 ?

Second question:
What is the extension period for the second extension ?

I think it is for 2 years ? And suppose I am allowed to apply for extension in 2014, will the extension given be 2014 + 2 years or 2015 + 2 years ( given my current visa expires 2015, but I apply in 2014).




Thanks for any info.
