The report came up with a scenario for growth if the UK had stayed inside the EU, and compared it to forecasts the Office for Budget Responsibility made in March last year.
Economists and analysts at Cambridge Econometrics - commissioned by London's mayor, Sadiq Khan - have modelled how the UK's economy would have acted were it still in the European Union.
Shyamoli Patel, principal economist at Cambridge Econometrics, said: "Our study reveals that London's economy would have grown faster if Brexit hadn't taken place.
Looking ahead, we project that Brexit will continue to have an impact on the UK and London economies in the medium term."
Mr Khan is set to use the report to make the case for a closer relationship with Europe on Thursday evening at Mansion House.
Mr Khan will add: "The cost of Brexit crisis can only be solved if we take a mature approach and if we are open to improving our trading arrangements with our European neighbours.
With a general election looming, Brexit will be an issue used to attack Labour and its leader Sir Keir Starmer, who backed a second referendum.
