Hi bullwicked,
You can see the following guidance on residence, domicile and remittance:
Residence, domicile and the remittance basis: RDR1
You will also need to take the statutory residence tests here:
RDR3 Statutory Residence Test
Once you have determined your residence status, you will be able to determine if the money being transferred in, is taxable.
If any of the money being transferred into the UK, is income or gains, generated in the tax year in which you become resident, then this will be taxable. All other monies, not from income or gains in the current tax year is not taxable.
You can see guidance on importing personal goods here:
Check how to declare personal goods you bring into or take out of the UK
Thank you.
