According to the firm, London topped the fraud league for first-party (customer) and identity fraud, whilst the mortgage and automotive industries were the most targeted during the year.
Delving into Experian's analysis of 2010 fraud reveals that around 20 in every 10,000 applications for credit and other financial products made last year were discovered to be fraudulent, up from 18 a year earlier.
2010 also saw a 25% increase in fraudulent applications for current accounts, with almost half of new cases down to identity fraudsters.
Experian's experts suggest that organised criminals could be increasingly looking to open fraudulent current accounts to launder money or provide a more convincing platform for targeting credit products offered by the same organisation.
Identity frauds targeting personal loans, meanwhile, increased for the first time in four years. Seven in every 10,000 loan applications were flagged as fraudulent in 2010, up from five in 2009.
The firm also found that identity fraudsters were responsible for 60% of these cases. Levels of identity fraud attempts to obtain new credit cards also stabilised at 19 per 10,000 applications in 2010, having fallen each year since 2006.
The analysis also revealed that identity fraudsters continue to misuse the identities of the wealthiest sections of society most frequently.
However, says Experian, young single people living in shared and rented accommodation from all sections of society are also amongst those most targeted.
The 2010 report reveals that automotive finance and mortgage providers were most frequently targeted by first-party fraudsters. Automotive fraud rates were up 31% on 2009 levels, with 38 in every 10,000 applications for car finance discovered to be fraudulent in 2010.
More than 80% of automotive fraud was first party, with more than half of it underscored by an attempt to conceal adverse credit histories, says the analysis.
Commenting on the figures, Nick Mothershaw, Experian's director of identity and fraud, said that fraud in the UK is a growing billion-pound illegal business with fraudsters resorting to innovation and inventiveness, targeting any perceived weaknesses in the system.
"Fuelled by the recession's aftermath, it is likely that financial services providers could see fraud attempts rise during 2011", he said.
