Haringey was the worst borough for the number of employees earning under the London Living Wage (LWW) last year.
The most up to date statistics, up to April last year, show 34.2% of Haringey employees earn below the LLW, more than double the rate of 13.6% across the capital.
Research from the TUC last week revealed 62% of childcare and social care workers earn below the Real Living Wage.
A Haringey Council spokesperson said: “Taking action to tackle in-work poverty and secure good jobs for our residents is a central part of our commitment to creating a fairer borough.
“As a council, we’ve been a London Living Wage employer since 2011 and were accredited in 2018, showing we are leading by example and doing what we can to make a difference for local people.
“We urge all businesses in the borough to do the same.”
The Living Wage Foundation certifies employers pay staff in accordance with the foundation’s rate in order to give accreditation.
They update the rate each year based upon the cost of living.
The figures, from the London Datastore, are based upon the ONS’ Annual Survey of Hours and Earnings.
Yet it also reveals those below the wage city-wide continued to fall and is now at its lowest since 2010, having peaked at 20.5% in 2018.
The Haringey Council spokesperson added: “To improve wage levels for those living and working in the borough we are currently producing Opportunity Haringey – our new inclusive plan to drive economic recovery and prosperity.
“Overall, we want to unlock and harness the strengths of our residents and businesses so we can build a local skills base alongside our investment in the local economy and supply chain.”
The LLW rose to £11.95 last September, having been £11.05 at the time of the survey.
The foundation will announce a new rate in October as high inflation continues.
Businesses will then have six months to raise pay and maintain accreditation as a living wage employer.
