The number of people claiming Job Seeker's Allowance in the borough has risen a sharp 7.7 per cent in the past year.
An extra 530 people are receiving the benefit, making the total 6,896, and this figure is expected to rise as the UK moves into recession.
Twice as many men as women are out of work, and Southall is the hardest hit with more than 200 joining the numbers, according to figures from the office of national statistics.
Health and adult services leader Councillor Mark Reen said the council would do all it could to help people back into work: "This is of course a worrying sign about the country's economic difficulties affecting Ealing, and it's important that the council acts as a source of local stability.
"The most important thing we can do is keep our hands out of people's wallets as far as possible without affecting services, and the Dickens Yard and Arcadia developments should be seen as a source of jobs and investment as we enter a difficult time."
Matthew Sims, general manager of the Ealing Chamber of Commerce, said the number of businesses and individuals attending the networking events and worskshops had risen.
Mr Sims said: "We face testing times over the next couple of years and we have to expect job losses. It's not surprising the number of claimants has risen. We are actively working with the council and other agencies to ensure business growth and prosperity in Ealing.
"The chambers are receiving more inquiries from organisations wishing to join and we expect this number to increase as we continue to support business development and ensure the public take advantage of the support available."
Action Acton, which helps people back into work, said more people were coming in for help and advice.
John Blackmore, chief executive, said: "The borough faces a very big task to support and help people back into work and off benefits and there is no doubt the increased numbers claiming Job Seeker's Allowance is to do with the economic recession.
"As a voluntary organisation, we work to help the unemployed, whether it is building their skills or helping with their CV and coming up with individual action plans. Losing a job can have a major impact on families but Action Acton is here to support people of Ealing."
