The capital saw more than 440,000 fly-tipping incidents in the year 2023-24, with 50 incidents of fly-tipping per every 1,000 residents - more than double the English average of 20 incidents per 1,000 people.
But Adam Hug, environment spokesman for the Local Government Association, said: "Councils are working tirelessly to counter the thousands of incidents every year and are determined to crack down on the problem.".
Some 60% of cases involved household waste, with 688,000 incidents of illegally dumped rubbish from homes, ranging from black bags of waste to the contents of shed clearances, furniture, carpets and DIY.
In total, English councils dealt with a record 1.15 million incidents of fly-tipping last year.
Nearly a third of incidents were the size of a small van load, while 28% were the equivalent of a car boot or less of rubbish.
