The University of York Students' Union (YUSU) has claimed more needs to be done to meet student housing needs with first years being outsourced to private accommodation providers.
Reports indicate that due to high demand for housing, 500 students this year were outsourced to private accommodation after colleges became oversubscribed.
Although the university doesn't guarantee campus accommodation for all, according to University Registrar and Secretary David Duncan, the system "is designed to be as fair as it can be."
With demand for university housing increasing, due partly to returning and postgraduate students opting for college accommodation, the university has put forward plans to develop two additional colleges with up to 650 rooms in each.
The university is now in the process of sourcing finance for the two developments, which if all goes to plan will be finished in 2019 and 2020.
Returning students have reportedly been told by the university that due to "higher than expected number of accommodation applications from first year undergraduate students" they would have to move some continuing undergraduates to alternative accommodation.
Millie Beach, YUSU President, said: "The University must not risk damaging the experience for students by taking on more then we can cater for in regards to accommodation or any other University facility."
The allocation of student accommodation at York has been a controversial topic for a number of years, as the system has been changed on a number of occasions.
