Tenant group Generation Rent has been crowdfunding in an effort to continue its work. It has now raised just over a quarter of its £60,000 target.
The organisation recently had its funding dropped by the Nationwide Foundation.
Yesterday, it had received £15,781 from 301 donators.
However, the group has less than five days to reach the target.
Separately, Generation Rent was given a donation by the Joseph Rowntree Foundation to use for a campaign for rent controls in London.
