U.K. financial adviser Hargreaves Lansdown PLC Friday said the first three months of 2010 were its "best quarter ever" after investors pumped money into pensions and savings accounts to shelter money from the taxman ahead of the end of the tax year on April 5.

Hargreaves said assets under management grew 13% to GBP17.6 billion during the first three months of 2010. Rising stock markets also helped.
