A proposed ban on "no-fault" evictions could be "chaotic" and "decimate" the student housing market, it is claimed.
The Renters Reform Bill was introduced in May, and this week charities urged faster progress.
However, Newcastle University students' union said the plans could "cause issues for tenants and landlords".
The government has said the bill would protect renters from a "very small minority of rogue landlords" who threaten eviction to silence tenants.
The bill would remove the right of landlords in England to evict tenants for no reason with only two months' notice, using the Section 21 process.
However, Section 21 notices are often used by landlords to officially end the one-year tenancies commonly used for student rentals.
Student tenants sign fixed-period agreements - known as assured shorthold tenancies (AST) - typically many months ahead of the new academic year. These will also be scrapped by the new bill.
