what can I check for?
and is bonded to a water pipe in the kitchen.
Cable is 2.5 put in around 1980 I am assuming the cpc is 1.5 but as you say could be 1m/m I will check it out

what can I check for?
1mm cpc / poor terminations at accessories of the cpc / remove the bonding & retest.
Kitchen bonding isnt a requirement now, so you could remove it if you so wish ( so long as its not the main equipotential bond)
Is it the old stranded stuff (3 strands for the cpc)? If so odds on its 1mm.
Off the top of my head I dodnt know what the multilier is for 1mm, Shakey may know if he's about.

Yes it could.
Thanks Easy fox, .80 ish was what I was expecting, what can I check for? going to use this circuit for assesment, so it's got to be right. It's an existing ring and has a few spurs on it and is bonded to a water pipe in the kitchen.

Easyfox, hi mate , where you been?
for 2.5/1.5 multiplier comes from dividing 2.5 by 1.5 = 1.66
so for old 1mm
2.5/1 = 2.5 for multiplier
