A breakfast and after school club currently based at Three Bridges Primary School is in search of a new home.
OSCAHS runs the clubs but due to changes being made at the school it has until July to find somewhere else.
Parents fear there will be no childcare available outside school hours.
Emilia Zarychta, who has a six-year-old son who goes to the breakfast club, said: “There’s no other provider in the area and to make childcare arrangements now will be a nightmare.
“I chose the school because they had this facility. We are both working parents.
“We are having to move to another school or give up a job.”
OSCAHS managing director Elaine Beach sought to reassure parents.
She said: “The problem schools have is classroom space is at a premium and they are education providers.
“They are also a community building owned by the community through the council tax. They should meet the needs of the community.
“However, if they don’t have room, they don’t have room.
“From the point of view of parents, they need reassurance. There will be something.
“We are finalising the details and as soon as I know, they will be the first to know.”
The school has told OSCAHS it can use space there until the end of the school year.
Chair of governors Dennis Cockerton said: “We have already identified that the space currently used by OSCAHS is required by the school in the future to best fulfil its educational obligations.
“The school understands the importance of affordable, quality, accessible and sustainable provision to meet the needs of working parents and carers and it is for this reason that we gave OSCAHS almost a year’s notice to research an alternative suitable venue for this facility.”
He added their priority had to be the future needs of the school.
Elaine Beach is viewing two properties this week but is open to offers from people with premises to rent.
She needs somewhere of at least 20 square metres with at least two toilets and kitchen facilities.
An outdoor paved or garden area would be an advantage.
