I Earn £466.94 each week how much will I earn each year

roughly £21,938 as your net pay (taking into consideration tax)
however, gross pay would be £24,280 ish (without tax)

Got a new job wondering how much I'll earn before tax deducted and after pls??

I agree with @heartz4moushi regarding income tax.

That said, you'll also need to pay National Insurance -- £22.49 per week (around £1170 per year).

You may need to include student loan repayments; your salary would be high enough to be making repayments on a "plan 1" loan or a postgraduate loan.

You'll be making pension contributions if you're auto-enrolled into a pension. These are optional, but I recommend that you don't opt out -- if you do opt out you're also giving up your employer's contribution plus the tax benefit.

Oh yea I forgot to take into account other compulsory taxes like n.i and council tax etc. (oh bills too if you want the money left over after ALL expenses) and the optional pension! So altogether maybe a hundred or two/three hundred less??

Council tax isn't deducted from your pay before you get it; while income tax, national insurance, and pension contributions are.
