The Department published the results of the test meeting the requirements of BS 8414 at the following link:

The attempted test did not comply with these procedural requirements and no advice could have been issued on the basis of the attempt. The Department has currently no plan to publish the report of that incomplete attempt.
In addition, acting on advice from the Independent Expert Advisory Panel, the Government has commissioned research to support further understanding of the fire performance of non-Aluminium Composite Materials (ACM) external wall systems. The tests began on 30 April 2019 and we expect to be able to publish the research findings in the autumn.
