Plans to axe Brent job centres in areas where 1 in 3 people are unemployed have been challenged by the council in a letter to the government.
Proposals to close the Job Centre Plus (JCP) buildings in Willesden and Kilburn were revealed by The Department of Work and Pensions.
The move to shut the two centres will put some of the most vulnerable residents in the borough at a huge disadvantage as they look for employment support, according to the council .
In both Willesden and Kilburn, around one in three residents are unemployed, higher than both the London and national average.
Brent Council has written to the Minister of State for the Department of Work and Pensions, Damian Hinds MP, criticising the decision and asking for it to be reconsidered.
The closures have been justified by the government as a measure to reflect how more people are moving online.
In the west London borough however, councillors have argued not all Brent residents have regular access to a computer, or the skills needed to apply for their benefits correctly.
Councillor Shama Tatler, Brent Council's Cabinet Member for Regeneration and Growth, Employment and Skills, said: "Closing the job centres is a decision that will affect the most vulnerable and the most in need the hardest.
"As well as losing such valuable support, residents will be forced to travel outside of the borough for their nearest job centre.
"The Marylebone Job Centre, based in Westminster , is the closest to the Kilburn centre, but is around two miles away.
"For support in Brent, residents would have to travel three or six miles to Harlesden or Wembley ."
She added: "How does it make any sense to close these centres where they are most needed and send these unemployed residents, some of whom will struggle with the travel costs, all the way to affluent Marylebone and Westminster to get the help and support that they need?"
In Ealing, protests have begun against the nationwide decision, which saw 50 people gather outside the Southall centre's doors from midday on Saturday (April 1).
Oliver New, chairman of Ealing Trade Unions Council, said desperate job-seekers would find it harder to secure work.
Mr New, who attended the protest, added: "Southall really has quite a lot of deprivation and it is a very mixed community, with people who speak a lot of different languages.
"So moving the job centre that has evolved would be quite a loss.
"Most people who live in Southall do not live on Uxbridge Road, which means that the great bulk of residents would have to get two buses to another job centre."
