People in Scotland appear to be among the most in search of advice with Motherwell entering the top ten hot spots while Kilmarnock jumped from tenth place to fourth.
The south continued to show strong demand for advice, with Stevenage and Salisbury remaining in the top three this year, ranking second and third respectively.
Meanwhile, Belfast, Glasgow and Edinburgh all moved out of the bottom ten.
Pensions, mortgages and investments were the top subjects for driving advice in 2014.
Within these advice areas, annuities, pension reviews and transfers, re-mortgaging, Isas and investing for income were the most sought after.
Karen Barrett, chief executive of unbiased.co.uk, said: "Truro tops the list for the second year in a row, showing that people in the South West continue to be more engaged with their finances than the rest of the UK.
"We hear from a lot of consumers that they simply don't know how to make sense of certain areas of their finances and therefore tend to put off dealing with them."
