ST Vincent de Paul is stocking nearly new items of school uniform in its shops and encouraging parents to donate any school clothes their children no longer need.
The charity has 32 shops across the north and said it is aware how expensive it is to prepare a child for school.
Proposed cuts to the school uniform grant have been suspended but the financial assistance will remain at last year's rate.
Anne Crossan is the regional retail services manager for SVP and said the charity has noticed increasing numbers of shop customers asking if school uniforms were in stock.
"While there is a government funded uniform grants' scheme, the allocation per pupil only touches the tip of the iceberg of what realistically is needed by a student. The cost of a basic secondary or grammar school uniform and PE kit can be daunting, in most cases in excess of £200.
"This is a challenging amount for most families, particularly those with more than one child who simply don't have money like this available and it adds huge pressure to those who may already be struggling to meet bills. However, the same uniform items in our shops would be a fraction of the price and in very good condition."
Ms Crossan also appealed for donations of school uniform clothing which is no longer needed and still in good condition.
"Just call in with outgrown items or even school equipment that is no longer needed and this could alleviate some of the pressures on another family. All donations are gratefully received and funds raised go back into supporting the work of SVP across local areas."
