Hi Guys. In 2016 when we started fitting metal consumer units i am pretty sure i read that the lid covering the circuit breakers hinge should be hinged at the top so that it doesn't get left down and potentially compromise the fire rating. I did an EICR this morning on what was a new build dwelling in 2016 that has a metal CU with the hinge at the bottom. The BG CU is still sold at a well known DIY store as i have just looked. Was the hinge requirement dropped. All i can find is 421-1-201 which mentions it's construction but no mention of the hinge position.
