EICR - C1 x1 + C2 x2 Please help!

[kerching]

C1 means that you have old lighting and other circuits in your home and according to that person if it is correct that there is no electrical work in house since last 25 years then obviously its need to go for Class 2 and needs to be rewire and also install smoke alarms and other security alarms as well. I suggest you to rewire your lighting circuits to be safe from future damage.

Please explain as I am fairly new to the trade?
