Tier2 from umbrella company OR from my own employer?

A dilemma :
 
My situation:
 
1.       Currently on PSW expiring in Feb-12.
2.       Working in IT in very good company on permanent position since 10 months.
3.       Earning £25,000 per year. ( which really less for me and getting calls for contract work with very good day rate)
 
I have two option:
Option 1: My company is ready to sponsor me with unrestricted COS. (Same salary and same work L I really want to earn more and work more)
 
Option 2: I have spoken to one Umbrella company who is ready to sponsor me as well but they will charge 23.5% of my salary earned. (But this could be still more than what I am earning right now). Is sponsorship from Umbrella company is Legal? Will it be any problem in future? Is this charges too high?
 
Please I will be really grateful for your suggestions and opinions on my situations.  Which option should I go with?

When I was sponsored by an umbrella company it was never more than 18.5% - and for most of the time I was paying 15%. The charges look pretty high to me!

Hi

I think marcus may have dealt with 18.5% + employer's NI, while the 23.5% may include employer's NI (13.8%). However, that is not the main point

I would say go with the direct end-user sponsorship if they offer a fair salary and good promotion prospects and will support you with sponsorship

Kind regards

Hi Muskan,

But I want to know, if an Umbrella company can sposnsor Tier 2. Did you find if it is legal? Can you please share the Umbrella company which was ready to sposnsor you.

Thansk in advance.
