Query regarding gifting money to my son in UK

Hi All, I have few queries regarding taxation in UK if we send money to my Son

Background: Recently We sold a property and paid a tax in India. Now we want to send this money to my son in UK.

Query is, will he be taxed again in UK if he receives from India. Please suggest on how we can send and tax free limit. 

Thanks in advance.
