Mayor of London Sadiq Khan has written to billionaire property owner Asif Aziz following allegations that his company is issuing large numbers of Section 21 eviction notices ahead of the planned ban on the practice.

The claims relate to properties owned by Criterion Capital, where several private tenants have reportedly received Section 21 eviction notices. Critics have described the approach as unacceptable given the government’s intention to abolish so-called no fault evictions at the start of May 2026.

It is understood that a number of residents living at Britannia Point in Colliers Wood, Delta Point in Croydon and Emerald House in New Malden, which collectively feature 606 flats, have been served notice to vacate.

Criterion Capital, a property firm that also owns the Trocadeo building in Leicester Square, said these were “routine and lawful tenancy matters” and denied it was accelerating action ahead of legislative reform.

A Mayor of London spokesperson said Khan is “appalled” at the reports and has written to Criterion Capital asking the company to “urgently explain their actions”.

“It is unacceptable to force Londoners out of their homes for no good reason – it leaves residents in an awful position, scared about the future for themselves and their family,” they added.
