Hi not to sure if i have uploaded the picture correctly .
If I have then, Does anyone know what CU can be used to replace this ugly old thing.
Due to it being in a small cupboard the size is limited.
Many thanks.

it looks attached to the meter board, which the DNOs do not like (they own the board and are entitled to remove or replace it at whim)
But that old Wylex Standard is very wide. When you measure it I am sure you will find you have room for a good big modern one.
Do you still use off-peak supply?

Never known a supplier refuse to do a simple job for which they can charge a fee in the realms of riches beyond the dreams of avarice....When a guy from the supplier come out he said he wasn't going to move it
