Scott, your pension contributions will be shown before tax as your income that is subject to tax will be reduced by your contributions. I've never seen a payslip that doesn't split ERS and EES contributions, but I've lived a sheltered life.
I always advise friends to put as much into their pensions as they can afford (subject to paying for new cars of course), many employers will match your contributions up to a certain level, but I don't know about yours of course. In the year before I retired (7 years ago) I was putting in 50%
I'm not and never have been a financial adviser so take what I say with that in mind.
