New employment - Tax question

[Moothead2]

I've recently started a new job and today I received a tax code for both my new employer and my old employer.

Should I contact the tax office directly or should I contact my old employer and have them sort it out with the tax office?

Thanks.

Rang the tax office today. Turns out there was an overlap between my old employer notifying the tax office I no longer work there and them issuing the tax codes so it's all been sorted.
