The Reserve Bank of India systematized the limit of money that you can transfer to the receiver account in UK. A person could not send more than USD75,000 every year to the overseas account till 2013. In 2014, RBI expanded the amount send to US from USD75,000 to around USD1,25,000. In 2015 again, RBI reconsidered the limit and further increased the maximum amount that one can send to the overseas account. At present, you can transfer upto USD 2, 50,000 to any overseas account in a year.
