The London borough of Richmond upon Thames is home to Britain's biggest savers, a study has revealed.
With an average of £29,765 set aside, residents of the borough's TW10 6 area have the highest overall savings anywhere in the UK, according to Halifax.
The amount is 380% over the figure for London and nearly five-times the national average of £6,074.
While people in the South East, South West and East Anglia all have above-average savings, those in the northern regions are falling behind, the study showed.
Average savings in the North stand at just £5,581, and East Midlands is the only northern region where the deposits compare favourably with the national average.
Out of the 50 postcode areas with the biggest savers, 32 are in the South - 19 among them in London and 12 in the South East.
Meanwhile, 12 of the top 50 areas for saving are in Scotland, with residents in the AB15 4 area of Aberdeen having the second highest deposits overall, having set aside an average of £26,130.
People in the SW15 6 area of Putney, the EH12 6 area of Edinburgh and HA7 4 in Stanmore, north London, all also have more than £20,000 set aside.
