Nelson Clark, 34, fraudulently applied for the government-backed loan three times in 2020.
The cabbie first applied for £30,000 from a bank on behalf of his N Clark Taxis business stating his annual turnover was £120,000 – an over-estimate of around £70,000.
Then two months later he secured another £100,000 from a different bank on behalf of two firms, Nelson Clark Management and Rosewood Motors, claiming they made a revenue of £200,000 each.
David Snasdell, Chief Investigator at the Insolvency Service, said: “Nelson Clark deliberately targeted a scheme which was set up to support genuine small businesses through Covid.
“Clark made false representations on not just one occasion, but three times within a two-month period.
“His actions were clearly dishonest and he made matters worse by spending the money he received for his own personal benefit.”
Clark, of Silver Birch Close in Bexley, was declared bankrupt in August 2021.
He then signed a 10-year Bankruptcy Restrictions Undertaking in March 2022, preventing him from being able to borrow more than £500 without disclosing his bankrupt status.
At Croydon Crown Court on Thursday (March 13) Clark was sentenced to two-and-a-half years in prison after he was convicted of fraud by false representation.
Mr Snasdell said: “Five years on from the start of the pandemic, the Insolvency Service remains committed to taking action against the fraudsters who cynically applied for money they were not entitled to during a national emergency.”
