DfE told us that, where a school hires portable classrooms, this counts as revenue expenditure. In this case, DfE checks that the expenditure is reasonable and the school does not have high levels of reserves from which it should be providing the funding itself.25 DfE also explained that it would talk to schools that wanted to be reimbursed for costs they had incurred for RAAC surveys. However, DfE implied that reimbursement might not be available for schools that had looked for RAAC as part of a broader structural survey.26 DfE emphasised that it wanted the process for schools to reclaim costs to be streamlined, but the process needed to include appropriate checks that claims were proportionate and properly related to the issue. At the same time, DfE said that it would err on the side of generosity, and expected to meet all reasonable costs.27
