London Boroughs performed worse than any other area, with Ealing, Newham, and Harrow being the worst overall.
The area with the highest proportion of zero ratings was Birmingham with 4.7 per cent of it's 1,249 cafe and restaurants getting the worst possible score.
LoveMyVouchers.co.uk carried out the most in depth study yet into food hygiene ratings for restaurants and cafes in the United Kingdom.
The company said: "In order to find out which areas of the country are doing the best when it comes to meeting the health and safety standards set out by the Food Standards Agency (FSA), we looked at the ratings that businesses have been awarded through the inspections carried out by local authorities under the Food Hygiene Rating Scheme.
"The statistics have revealed some very interesting results."
