12pc of wages spent on work expenses

The average worker spends one pound in every eight - totalling £1,843 a year - on costs relating to their job.

Britons collectively spend £66.9bn a year on costs specifically related to their jobs such as food, travel, childcare, equipment and clothes, according to the study by Santander 123 World.

Researchers said that 12pc of the disposable income of someone with a full-time job is typically swallowed up by these costs.

London's employees are the hardest hit, spending on average £3,561 a year. Workers in the East of England spend £2,542 per year and those in Yorkshire and Humberside spend £2,535.

Workers in the West Midlands incur the lowest costs at £1,668, followed by the East Midlands with £1,688, and the North East with £1,896.

The figures recorded before last week's hike in travel costs show workers already spend the most on commuting, forking out an average of £782 a year on public transport.

Drivers, however, spend more, with £829 spent on fuel, £65 on parking and £32 on congestion charges.

The one in five workers who pay for childcare spend £3,632 a year on childminders and nurseries.

Lunch and snacking sets workers back £410 a year, with a further £142 spent on work calls not claimed on expenses, £27 on computer equipment and £18 on stationery.

Employees shed more money by putting an average of £153 into their personal grooming, £83 into clothes and spending £77 on colleagues and clients.
