End of contract fees

My stepson has just moved out of a flat in London which he has been in for exactly 1 year.
The landlord says she is charging him and his co shares £75 each as end of contract fee. From my understanding surely this is illegal. Can you confirm please.

You are right. End of contract fee is illegal

Do not do it the landlord is in the wrong. There are certain “groups” of landlords/people. who will do anything to get extra money. They spin any old yarn and just lie glibly ,money is their God
