Kensington & Chelsea Borough tops the index as the hardest place to run a small business in London, due to higher costs and greater local administrative burdens.
And Bromley, Barking and Dagenham stand out as the most attractive boroughs in the Capital for small business owners to operate in, by providing the least burdensome environment; rather than Shoreditch, Hackney, where so much of startup and small business investment is targeted.
Havering, on the other hand, has the greatest infrastructure challenges, while small businesses in Westminster enjoy the most beneficial infrastructure.
Kevin Smith, senior partner for KPMGs mid market practice in London, said: The small and start-up business community is essential to keeping the Capital dynamic, innovative and attracting foreign investment to London. However, with the Capital becoming increasingly expensive, it is imperative that policy makers act to ensure that small businesses are not driven to the outskirts of London, with the more accessible parts of the city being left as the playground for the big, global corporates.
A survey from across the 33 London Boroughs, featured in the Index, found that 84 per cent of small businesses viewed Broadband quality and availability as a significant factor to the success of their business.
Almost eight in ten businesses rated the quality and availability of public transport as significant to their business success.
