FirstRate5® is an easy-to-use interactive tool with a graphic user interface that enables designers and thermal performance assessors to generate energy ratings for a home by tracing over floor plans.

Changes to the generation of the FirstRate5 preview certificate

by FR5 | Nov 08, 2019
Changes have been introduced to enhance the security of the FirstRate5 preview certificate.

From Friday 8 November 2019 (11:45 AM) preview certificates generated on the FirstRate5 website will be converted to images and a greater area of each page will be covered by the preview watermark. These changes will increase the file size of a preview certificate to approximately 1 MB.
Please note that these changes will not affect the production of the final purchased certificate in anyway.
