Waltham Forest has the highest percentage of jobs paying below the London Living Wage in the capital, figures from charity Trust for London show.
Some 37% of jobs in the borough have a salary below the London Living Wage, while a total of 30% of jobs in Redbridge pay less than it, according to the group.
The charity found low paid jobs are hitting outer London harder than inner London, with the overall percentage of low-paid jobs in London at 19% - the equivalent of 730,000 individual jobs.
Waltham Forest had the highest proportion of low-paid jobs at 37%, but because it has a relatively small total number of jobs it only has 17,000 low-paid jobs.
Cllr Simon Miller, cabinet member for economic growth and high streets for Waltham Forest Council, said it was "one of our top priorities... to improve our residents' life chances by tackling low wages and in-work poverty.
"The council is an accredited London Living Wage Employer, which means it pays all employees the London Living Wage at a minimum and is also committed to working with our supply chain to secure the London Living Wage for their employees."
A spokesman for Redbridge Council said: "Low pay is a major problem for our residents. This isn't a challenge that the council can fix on its own, but we are committed to acting where we can.
"All our directly employed staff are already paid London Living Wage and we are committed to extending this to our contractors, improving lives for hundreds of our residents."
