Doh! wrong cable size :/

Depends. Some circumstances would allow 16mm2 tails and 10mm2 earthing conductors.
What's your earthing arrangements (supply type) and size of fuse in cutout?

Why on earth is there so much copper showing on the bottom of the isolator 
What does it say on the other side of the DNO fuse? Is there any indication that it is PME (TN-CS)?
The single RCD protecting the whole installation is a bit poor too

I think you have a bit too much conductor exposed there on the tails to the fuseboard.
What is the rating of the fuse under the meter ?
How long is the total run from the cut out to the consumer unit ?
Regardless of this I personally would just install 25mm L&N and a 16mm earth.

Your service fuse may be 80amp. If so, 16mm is fine. However, to comply with the table in the regs, you would still need a 16mm earth.
Only if it's PME (which we can't tell from the picture).
If it's TN-S then the earthing conductor can be sized using the adiabatic equation.
That's sounds good enough to me. Thanks
Because the existing tails are not long enough to route properly. They would have to drape across the wall (as they do currently). A balls up by Scotty Power.
out of interest did scottish power also do that terrible termination on the bottom of the isolator?
Also i notice that you seem to have removed the cover from the output terminals of the isolator without turning it off first. In general this is not reccomeneded. Especially if you haven't opened the enclosure before or you know the wiring in there is badly done.

The meter board used to be closer to the CU until they moved it further away , hence the cables draped across the wall. The cables used to nicely route along the coving and down onto the meter board.
Yup.
Not quite right there. I did indeed turn the power off and then removed the cover. I then touched the neutral tail and it promptly fell out
I re secured it properly, and the cover will go back on when I have replaced the tails. Obviously I won't do this without turning of the power yet again. Currently 3.5m. They need to be 4m long to make it.
Completely agree. And that's what I will buying tomorrow AM
I'm hoping you mean Scotty power and not me !
