Income before moving to UK

Hi there, I got my BNO visa and in a discussion with my company whether I can transfer my role and contract to UK later this year, however, the management would like me to visit for a week as business trip in June to meet the local team first while this period of time I will be employed under this same company by contract from Hong Kong. In this case, if I move to UK this year (let say Sep), whether I will be taxed from the period that I visited UK in June? Thanks!

Hi,
It will be the September.
Thank you.
