An engineering manager from Borough Green has admitted cheating the taxpayer out of more than £100,000 in benefits.
David Rothwell, 66, pleaded guilty to seven counts of benefit fraud totalling £109,152.53 at Sevenoaks Magistrates' Court on Monday.
Rothwell claimed Jobseeker's Allowance from December 2002 until April 2009 but failed to tell the Department for Work and Pensions when he found employment at Imperial College in London from January 2004 until March 2007 and then at John Laing Integrated Services from August 2008 until the present day.
He also admitted carrying out housing and council tax benefit fraud against Tonbridge and Malling Borough Council for more than 11 years, from January 2004 until May 2015, when his offences came to light.
Rothwell, an engineering compliance manager and maintenance coordinator for John Laing Integrated Services, claimed all the illegal benefits on the grounds he was unemployed.
Lead magistrate Beverley Charman passed jurisdiction on sentencing to the crown court as she said her powers were not sufficient.
Rothwell will next appear at Maidstone Crown Court for a pre-sentencing hearing on Monday, February 29.
He pleaded guilty to two counts of falsely claiming Job Seeker's Allowance and four counts of falsely claiming housing and council tax.
He also pleaded guilty to a final charge of falsely claiming pension credit from the Department for Work and Pensions.
The frauds ran for years.
