First for Childcare - York in Audax Close at Clifton Moor on the outskirts of the city, formerly known as Happy Jays, sent a letter home to parents on Thursday (November 7) informing them of the closure.
They say that there has been a subsequent change of leadership at the York site and they are working with Ofsted.
It says: "Sadly we are having to close next week as we have had a visit from Ofsted.
"Some actions were provided by the local authority some weeks ago, that no one outside the setting knew about and only discovered yesterday.
"Because we have not completed these directives we will have to close to complete them.
"Ofsted have been very supportive as they know that we didn't know anything about this.
"We have already started these and it's things we already know how to do as it's standard practice."
The nursery has offered parents places at one of their other sites in Harrogate with the possibility of using a minibus to transport the children there next week.
