This follows an increase of £600,000 in the past four months, including a £372,874 increase in the past month alone.

In just under a year, the total fines for letting agents and landlords has increased by over £1m, from £6,052,932 in December 2020, to £7,128,973 at the start of November.

Since the start of this year, Kamma has reported an average increase of £89,670 in fines every month.

Camden council topped the enforcement league table as the most active in terms of number of fines, followed closely by Newham and Southwark.

Hammersmith and Fulham was found to be the London borough with the highest average fines (£19,800), followed by Hillingdon (£13,500), and Hackney (£11,250).

Orla Shields, chief executive at Kamma, said: “The lettings market is more regulated than ever before.

“Licensing schemes, fines and enforcement through Rent Repayment Orders are all increasing, so it’s vital agents act to protect themselves, their landlords and of course their tenants.”
