Is a metal or plastic fuse box better?
Should I get a new metal or plastic fuse box? My old one needs replacing and I've seen different advice.

According to BS7671 18th Edition, homeowners should install a metal unit for a new installation.
Where the confusion arises is existing consumer units/fuseboxes. Landlords have to complete electrical safety checks for their properties. This is an EICR Certificate. If a plastic fusebox is present in the property, the electrician will typically record this as a Code 3 (C3) observation. This means improvement is recommended because the unit does not comply with the existing regulations (18th edition) but does not present immediate or potential danger. So an EICR certificate can still be issued even with C3 observations.
A bit like a car MOT with advisories!
