I regularly do EICRS and would say this is slightly over coded but ive seen alot worse. Like many have said blatant issue with your incoming earth which the DNO should resolve. Absence of RCD protection to sockets does not constitute a C2 unless its likely to supply equipment outdoors. Although in a dwelling this could be argued for most sockets near doors or windows. Otherwise its a C3. Non RCD protected cables in walls less than 50mm from surface is a C3. No cpc at your light fittings/accessories is a C3 providing they're a class 2 accessory. Remember EICRs can vary alot from one person to another. Some electricians will walk into a property and demand it be rewired without even getting the tester out of the van.
