Money transfer from India to my son in the United Kingdom

You need to visit your Bank and ask them to initiate an international transfer. They would convert the Rupees into GBP and transfer. There is also a fee for transfer around Rs 1000 to Rs 1500/-

If you have an account with large Government Banks or leading Private Banks, it should be quite simple by approaching the Bank.

I've been doing it through Remit Now. It's a secure online Foreign Outward Remittance platform provided by HDFC Bank. Sending foreign outward remittance is now as easy as transferring funds via RTGS/NEFT.

All you have to do is Add a Beneficiary > Select Funds Transfer > Input the amount to be transferred > Accept the T&C > Confirm the details

Generally banks offer wire transfer to foreign banks. Every year , maximum 250K USD can be sent at max outside India, as per RBI liberalized remittance scheme.

Approach your bank, where you are having savings account. They will be able to help in the wire transfer to your son's UK bank account.

For e.g., ICICI is having many options to send money abroad from India:
