Your UK residence status affects whether you need to pay tax in the UK on your foreign income.
Non-residents only pay tax on their UK income - they don’t pay UK tax on their foreign income.
Residents normally pay UK tax on all their income, whether it’s from the UK or abroad. But there are special rules for UK residents whose permanent home (‘domicile’) is abroad.
Your tax liability will depend on your resident status.
It's very simple and talk to the revenue guys they are very helpful as they hate paperwork as much as we do:

Work out your residence status
Whether you’re UK resident usually depends on how many days you spend in the UK in the tax year (6 April to 5 April the following year).
You’re automatically resident if either:
you spent 183 or more days in the UK in the tax year
your only home was in the UK - you must have owned, rented or lived in it for at least 91 days in total - and you spent at least 30 days there in the tax year
You’re automatically non-resident if either:
you spent less than 16 days in the UK (or 46 days if you haven’t been classed as UK resident for the 3 previous tax years)
you work abroad full-time (averaging at least 35 hours a week) and spent less than 91 days in the UK, of which less than 31 days were spent working
