Hi
HMRC cannot comment on future events as legislation may change. however, for current guidlines, please refer to
HS321 Gains on foreign life insurance policies (2023)
For any interest/dividends that are received, that could be taken by you, are classed as taxable income and should be declared.
You do not need to report any increase in value of the policy until it is surrendered/matured and is subject to possible income tax rather than capital gains.
Thank you
