We have a New Logo!
Castline Systems have grown and developed over the years and we felt it was time for a change. After careful consideration we have refreshed our logo to reflect a more modern look and to represent who we are today. We are proud of this change and hope you like it as much as we do.
BS7671:2018 18th Edition
FormFill and CableCalc have been updated to include the changes required by BS7671:2018. The minor works certificate has changed substantially and the EIC/EICR have new inspections to be undertaken as well as two new columns on the schedule of test results. For Windows this is a new version 12 program that will run in conjunction with previous versions, allowing you to access your certificates in the old formats as well. The Mac OSX version includes both old and new format certificates in the same program.
If you subscribe to Upgrade, Maintenance and Support or either of the Annual License Schemes, you can access the latest versions from the customer area. If you have an older version of our software and are outside of a support subscription then please contact us for an upgrade price.
The iPad and Android apps have also been updated to be compatible with both version 11 and 12 of FormFill.
