ULU has been at the forefront of lobbying and political activity in the capital for many years and is now rallying support for a campaign to stay open following a review by London University that suggested ULU would close soon.
Campaigns have included a push for cheaper housing and better pay for working students.
More than 4,000 supporters have already signed a petition supporting ULU.
The student union has also issued a statement denying reports of closure, while confirming ULU would remain open until at least July 2014.
ULU also pointed out that no students sat on the review committee, which gave an unfair slant on the services provided by the union for students in the capital.
The review highlighted that ULU was expensive to run and that many services provided to students were offered elsewhere or could be run more cheaply.
The union counters that much of the grant received by ULU goes straight back to the funders as rent.
ULU countered that political activity was not the union’s only role.
“ULU helps to bring students together in sports clubs and societies, giving them the opportunity to meet like-minded people,” said a spokesman. “With London so expensive city to live in, the provision of such services is much-needed.
“If this decision goes ahead it will establish a precedent whereby the managers of a university can whittle down, decimate and abolish unions arbitrarily. This would be dangerous at the best of times, let alone in a period when publicly funded higher education is coming under attack from government and corporate interests alike.
“We need unions that are more than just bars and night-clubs – we need democratic organisations that give us a voice.”
