Colour on old fuse board

[SALL2009]

I have an old wire fuse board, which I am getting replaced shortly. I want to isolate some redundant connections (electric cooker etc) so I can get the electrician to disconnect on the new CU.

My fuse board has 6 fuses on it. 2 red, 2 blue and 2 white. Can someone tell me which colour is for wall sockets and cookers etc. I know I can turn off one at a time to work this out, but it would save me hassle if I knew which two are the ones it would be.

Why bother?

When the electrician replaces the CU the first thing he will do is to turn everything off and then remove it - hey presto, circuits isolated.

I just want to make sure nothing else is spurred off the cooker socket. i will remove the fuse for the cooker socket and then test all other sockets (extractor fan etc) and if only the cooker socket is dead and everything else is still live. I can tell him to get rid of it.
We also used to have an electric water heater. It has been removed but the electrics are still live to a junction box where the tank used to be. I also want to check if this is also an independent feed from the fuse board. So he can get rid of this too.

Found the info I was after.

Why get rid of a cooker circuit?

How do you know you won't ever need it in the future? Whilst gas is great for hobs, electricity is better for ovens.

Shower pump?

Towel rail?

Removing circuits can mean a lot of disruption and damage - just leave them.
