This function is designed for use by Ofgem, energy suppliers and installers of CERO Rural and HHCRO Rural measures wishing to validate CERO Rural and HHCRO Rural specific data.

Data should be uploaded as an Excel spreadsheet (Excel 97 format or newer) using the template provided here. The tool will then perform area based eligibility checks on the data and allow the results to be downloaded as a CSV file.

Note: CERO will close on 30 September 2018 so this tool should not be used to identify CERO eligible postcodes after this date.
