Issue of replacement vouchers by Health Boards or NHS trust
11. Where, on an application by a patient within six months of a voucher having been issued to him under regulation 9(1) or 10(1), a Health Board or NHS trust is satisfied, having made such enquiries as it considers relevant, that the voucher has been lost or destroyed without having been presented to a supplier of optical appliances, it may issue to the patient a replacement voucher completed in accordance with regulation 9(2)(a) and (b) and 10(2)(a) and (b), but with the date of issue of the voucher being that on which the replacement is issued.
