The gender pay gap has been one of the biggest problems facing gender equality in the workplace over the years. But new research suggests the pay gap actually starts from a very early age.

A survey by Halifax actually found that on average, boys receive 13% more pocket money than girls.

The annual poll of 1,200 children and 575 parents found that the average child received £6.55 a week - the highest figure since the start of the financial crisis in 2007.

However, the average boy aged 8-15 received £6.93, compared to £6.16 for girls. The 13% gap marks a rise from just 2% last year. And boys were more likely to complain about not having more, as well. In total, 40% of children surveyed thought they should receive more pocket money.

Halifax also found that more and more children are saving, not spending their pocket money. Nearly eight in 10 (79%) said they save at least some of their weekly allowance, up from 70% last year. And the number saving all of their pocket money rose from 10% to 12%.

Giles Martin, head of Halifax Savings, said: "It's reassuring to see that the average weekly amount has reached a nine-year high.

"It's likely it'll be a few more years until we reach the dizzy heights of £8.37 in 2005 though, when we saw the highest average pocket money since our records began."

Perhaps unsurprisingly, children in London received more pocket money than anywhere else in the UK at £8.21, more than £1 ahead of second-placed Scotland on £7.06. The East Midlands (£5.33) and East Anglia (£4.96) were the lowest paying areas.

Tom Castley, vice president EMEA of Xactly, said: “The gender pay-gap is an ongoing battle, and this latest research from Halifax's annual pocket money survey highlights that the problem starts from an early age.

"Boys on average receive 13% more pocket money per week than girls, and this currently continues into working life. In London alone, women earn on average £7,000 less than their male counterparts and gain almost half of what men do in bonuses – women only receive 16% of their salary compared to 23% for men.

“This cannot continue any longer. Businesses failing to suitably reward their staff, regardless of gender, will ultimately fail to gain the most from their employees and will be limited in their success. Eradicating the gender pay gap should be a priority for every UK business."
