Help with storage heaters on eicr

[Zahid Nawab]

Hello all, I have been asked to do a eicr on a property, as the client has asked to rectify any issues as I go along, I have come across a supply to some storage heaters running off a oldb3036 consumer unit. It is running off a 24 hour supply ie 4 terminal meter but within it has contactors. I need to change this board but how do I approach it and where do I start I ve posted some pics the contactors are within the consumer unit. Is there a consumer unit to replace it or something else I can purchase

Thank you all for the input. How would you treat it if you was doing a eicr?

Those two fuses are C1. The missing cover is C2.
Assuming the storage heaters are correctly sized so as not to overload the 2.5mm2 cable as it is installed, then the 30A fuse is only providing short circuit protection, so the 2.5mm2 is fine. No different than the 2.5 forming a spur off of a RFC.
