Bulk data are available for an annual fee: "The CRO supplies, under licence, data in bulk format for high volume users of our data. The data concerned is company information in respect of all companies on the register. It is in a specified format which may be updated to take account of changes in filing requirements. Daily updates of the data may be downloaded via the internet - a password is assigned to a Licensee to facilitate this.
