NI and tax advice please and company pension

wannaberich41

Hope this is ok to post.  My mind has totally gone blank and hope someone can kindly help.
in October I was made redundant after 28 years working for the same company.  I was on job seekers until April/May time.  I’ve just started my first job since which is only a temporary one until possibly end of November.
I noticed they’re deducting tax and national insurance.  Should they be doing this yet as thought there was a minimum you earn before getting charged this?
Is there any way of seeing my tax and nI contributions the gov at all?
How would I calculate my tax code I should be on if I should be paying it?
also they’ve signed me into the company pension scheme,  would this be compulsory or could I opt out as my position is for just a few months?
if can’t opt out or shouldn’t can I add the 2 different pension companies into 1?  

Apologies for all the questions.

Yes it should be deducted, HMRC don't know it's a temp role. Any refund will be next year after HMRC reconcile everything.

You can opt out of pension, but it's free future money you're giving up.

You can transfer the money to one of your other DC pensions when the assignment is over, assuming they accept transfers in and you're likely to never work for that agency again or use that pension company again.

Ni is charged on what you earn in any pay period there is no annual allowance in the way that there is with tax so assuming the correct figure was charged then that is the NI you have to pay.
Regarding tax what tax code are you on?
Have you had taxable earnings this year eg Jobseekers?
Did you have a P45 for this tax year from Jobseekers?
If not did you make a starters declaration along the lines of selecting A B or C?

You should have had a letter about enrolment into the pension which would have set out your rights to opt out. Did you? (Yes, I accept the free money, and I'm not saying opting out is the best thing to do, but on short-term contracts I can understand the attraction.)
