Westminster City Council raised £130,000 from fly-tippers in the year since it was first allowed to issue fixed penalty notices (FPNs) for the offence.
Figures obtained under the Freedom of Information Act show west London councils raised more than £159,850 from 973 fly-tipping FPNs between May 2016 and May 2017.
The vast majority of the FPNs - 747 - were issued by Westminster. The second highest total - 126 - was issued by Barnet Council.
However, all revenue raised by the council through FPNs for fly-tipping is retained by a third party, so it was unable to disclose how much it had received.
The state of London's streets
Kensington & Chelsea raised £14,000 with 42 FPNs, an average fine of £333.33, and Ealing raised £11,750 with 40 FPNs, an average fine of £293.75
Three west London councils - Hammersmith & Fulham , Hillingdon and Kingston - issued no FPNs for fly-tipping during the period.
Harrow issued six, raising £1,200, and Richmond issued 12, raising £2,900.
Local authorities first gained the power to issue on-the-spot fines for fly-tipping in May 2016.
