The Commissioners maintain a large number of databases for internal use and listing these would involve a disproportionate amount of time and cost. However, I can tell the hon. Gentleman that their accuracy is constantly verified during data input.
Among the more significant databases controlled by the Commissioners are the clergy payroll, lists of redundant churches, and details of bishops' expenditure. In all cases there are robust processes for ensuring accuracy, data is updated and checked against external sources where possible, and we estimate a high percentage of accuracy.
