Split year treatment on return to the UK

I returned to the UK in the 2023/24 tax year and appear to meet the criteria for case 8 of the split year treatment, and no other case. I had a residential property, jointly owned with my son, in the UK that was rented out on a commercial basis until 14/08/2023. The property was then vacant as maintenance work was required before I could occupy the property due to damage caused by the outgoing tenants. I returned to the UK on 07/10/2023 and moved into the property at that point. Which of the two dates would be the basis for my split date in this instance?

Hi Graham Westwood,
It is the date that you arrived in the UK that the split occurs.
Thank you.
