This report has presented the results of one of the first studies of financial wellbeing among UK employees. The literature review showed that debt problems are relatively widespread across the UK but there is no comprehensive source of information on the numbers of people affected. The Thoresen Review (2008) estimated that 7.5 million people may fall into the most vulnerable group which is likely to suffer financial problems. The evidence reviewed for this report, including information from some of the debt advice charities, suggests that a substantial proportion of those affected by debt are in employment, and debt is by no means the preserve of people outside the labour market. There is also consistent evidence to suggest that both debt levels and the numbers of people affected are growing. The survey data has illustrated the importance of using both subjective and objective measures of financial well‐being as the former can capture concerns about future financial problems, whereas objective data is more readily available to assess immediate financial status. There appear to be plausible links between poor financial well‐being, stress and mental health problems, though the causal relationships between these factors are likely to be mutual. Studies from the United States claim a significant impact of poor financial well‐being on individual performance in the workplace, relating this to outcomes such as absence, alcoholism and workplace violence. Like the results of the survey conducted for this report, the studies reviewed rely on self‐reported data from employees on their performance and this requires supplementing with measures of employee output and organisational performance for a more accurate assessment of the impact of financial well‐being on employers. The surveys from which data was drawn for this report were conducted on a relatively small scale, but there are a number of indications that the findings are credible. The results appear to be broadly consistent in terms of the types and levels of debt that survey respondents report with those found in the wider literature. Their average income is also broadly consistent with the UK national average.
