The cost of Business Parking Permits in London has risen by an average of 81 per cent in ten years.
The Federation of Small Businesses says costs such as this are stifling business growth.
Many of London's market stall holders have lost the spaces they need for trading.
The Federation of Small Businesses and London First have launched the first 'Small Businesses Cities Burden Index' to show how London fares against its major international competitors.
The research shows that London is the seventh costliest city for small businesses to carry out business activities in, when compared to major cities in 23 other countries.
The analysis shows London's position is as a result of a high costs burden, although lack of access to finance and infrastructure impediments such as transport were also important factors.
The Federation of Small Businesses has called on London councils to freeze or reduce their business rates for small businesses in the Capital. A new survey conducted by the FSB found that one in ten of respondents were paying more in business rates than they were in rent.
Small businesses are urging London councils to re-think their parking rules, saying they are being badly affected by new charges.
The Federation of Small Businesses has created a parking map, to raise awareness of the issue. Glen Goodman has been to one High Street to find out more.
It is hoped a new map which allows small businesses to log the effect of parking charges on business will urge councils to take action.
In a survey 75% of small to medium businesses said that parking charges were a major issue for small companies, equal to business rates.
A spokesperson for the FSB said one recent council to make improvements was Wandsworth.
Parking charges were slashed by 50%, this is something the federation wants throughout London, affordable parking to boost trade.
Spokesperson for the FSB said "some councils that have increased parking charges and moved to ticket-less parking machines have seen a decrease in revenue."
