Leaving from the UK - tax situation

[joshua.pearl3]

I would greatly appreciate your help.
I have been living and working in the UK for 8 years. (This year I will file a tax return for the first time as my annual income exceeded 100k last financial year.)
Mid-September I left the UK as I found a job in Switzerland.
I have spent c160 days working in the UK with income below 100k.
I have a question:

I understand I need to file the P85 form to get the overpaid tax. Will the UK want to tax me for my earnings in Switzerland? I am a bit confused with the split year treatment. Technically it is unfair as I am already paying taxes here.

If you've left the UK to work full time overseas and will continue to do so until at least the end of the proceeding UK tax year, then generally you will be considered non resident from the date you started working overseas. This is case 1 of SYT and there are specific tests to consider, but if it is the case then your Swiss income, assuming no UK workdays, should not be taxable in the UK.
