Hi,
Inheritance tax would only be of relevance if the giftee was resident in the UK at their time of death and the gift was made within 7 years of their death.
The gift would then be considered part of their estate for inheritance tax purposes.
If your parents are non resident, but have UK assets, such as property, then inheritance tax may apply on those assets if the thresholds are exceed.
There are no tax implication for you to receive the gift. Further guidance can be found at
How Inheritance Tax works: thresholds, rules and allowances.
Thank you.
