It looks like 6.0mm from the CU to the isolator, and then 4.0mm from the isolator to the shower.

99%sure that they are the same size cable

Think its the perspective on the isolator photo

I can measure the copper with a vernier tomorrow if that helps?!

I was just thinking I could scrape together £40 for a new slightly more powerful shower instead of £10 for the replacement pressure release device for the existing shower.

£5.49

Its not that bad, just not very powerful at all.

Nor is an 8.5kW, really.

Seriously - wait until you have the funds to have the circuit rewired and a 10.5+kW shower installed.
