Median financial wealth among the UK's highest earning households increased by 64 percent between 2005 and 2012 —13, the study, entitled "Wealth in the Downturn: Winners and losers" shows.
Meanwhile, the lowest-income group has become less financially secure, with median financial wealth 57 percent lower than in 2005.
Young workers are also among the losers, the study found. Wages for 26-35 year-olds fell at a greater rate than the average in light of the crisis, and persons in this age group are considerably less likely to own a home now than 10 years ago.
In general, UK households were poorly prepared into the financial crisis, according to the study.
The country's 2008-2009 recession, triggered by the global financial crisis, was the deepest since the Second World War.
