Adding another circuit to and old cu

[Lexicon]

I need another radial circuit adding to our cu board to supply a new shed / workshop. We had an an eicr done before moving into this house a year ago and the cu was deemed unsatisfactory because in does not comply with current standards, being installed in 1979. It does have rcd protection rated at 100ma.
Can a new circuit be connected under current legislation? or is a replacement CU mandatory?

Can you post a picture of the old board.

So you spent many many £000's on buying a house including due dilligence and getting an eicr done, but have decided not so spend a few £00 getting the electrics upgraded, which you knew before you bought needed to be done?

Perhaps now is that time?

The radial might not need RCD protection at 30 mA
