FOI 1887 - Incidents due to fake or non branded phone chargers

Could tell me how many house fires or incidents have been caused by non branded phone chargers?

Currently the Cheshire Fire and Rescue Service Incident Recording System (IRS) has insufficient facilities for the comprehensive recording, and subsequent analysis, of the involvement of fake or non branded phone chargers at fires attended. Therefore, due to the specific information asked for, we cannot provide the data requested.
