Hi,
Please see Tax on foreign income: Overview - GOV.UK (www.gov.uk) which confirms as UK resident you are required to report your foreign income to the UK.
Tax on foreign income
If this relates to self employment, you will declare the income in your self employment section and claim any Foreign Tax Credit Relief in the foreign section of the Return. If employment, you will show in the employment section and again claim any Foreign Tax Credit Relief in the foreign section.
Thank you.
