Traders in Isleworth who face £1,000 fines unless they pay for a licence to use the pavement outside their shops have accused town hall bosses of failing the area's small businesses.
Shopkeepers in St John's Road have been ordered to either remove stock and street furniture or pay £750 for a street trading licence.
But they believe the amount is extortionate and claim Hounslow Council is simply trying to make money out of them and are calling on officials to bring its charge in line with neighbouring boroughs before their businesses start to suffer.
Linda Cash, 47, who co-owns the neighbouring Syon deli with partner Tim Zekki, has been forced to remove table and chairs from the street. She said: With a new business it's difficult to advertise if you've not got any street furniture. Hounslow Council seems to be anti-small business."
Warren Bushaway, 28, owner of florists, Star Gazers, added: "We rely on passing trade and people browsing outside the shop. It's going really well but I can't run this business if they enforce this."
In neighbouring Richmond the charge is around a tenth of Hounslow at £228 over a fixed three year term. But a Hounslow Council spokesman said the charges take into account administration fees and the costs of enforcing the legislation.
"Unfortunately the amount of illegal street trading has increased significantly in the last few years and more resources are needed to tackle the problem," he said, adding that fees have more or less risen in line with inflation.
