A buy to let landlord who converted an Uxbridge house into two flats without planning permission has been ordered to pay £108,000, following legal action by Hillingdon council.
Mohamed Omar Hassibi, 64, was prosecuted for breaching a planning enforcement notice requiring him to revert his property back to a single dwelling.
At a sentencing and confiscation hearing at Isleworth Crown Court, Hassibi - who previously pleaded guilty - was fined £1,000 and ordered to pay the council's costs of £7,000.
The court also imposed a confiscation order of £100,000, requiring Hassibi to pay the sum within three months or face going to jail for four months.
The prosecution was brought jointly by the council's planning enforcement team and a trading standards task force that specialises in recovering proceeds of crimes.
"Mr Hassibi was generating a large rental income - around £2,000 a month - from unwitting tenants and it's only right that he should handover the money he earned from his illegal activity. We are committed to ensuring that crime does not pay" says a council spokesman.
