Hi all,

Easy enough and possibly very silly question. when moving a supply, if there are 2 sets of 25mm tails in the meter box (one to the CU for the house, second set to a 63A switch fuse supplying an annexe, will the DNO terminate both sets happily enough?

Thanks,
 
Can you show a pic?
 
The meter only has one pair of outgoing terminals. I think one set of tails from meter to 2 pole service isolator, then from there to 2 x 100A blocks (Henley) and then out to whatever consumer units

Sorry was in a rush to get down to a curry that had just been delivered earlier. This is supply move into an extension. Currently under the stairs in the house, now has external inset meter box on the extension with board to go on the other side of the wall.

The above quote from littlespark is exactly what I had planned, then through the wall from the external meter box, up in some PVC trunking and into the board and fuse switch. Wiska CU relocation kit to extend the existing from the house, for the time being.

Essentially I guess all I am asking is if I stick 2x 100A henleys in the new meter box, with the 2x pairs of tails in them before the DNO get there to change over from the existing under stairs supply, will they be unhappy that I have mounted said henleys in their box?

No, as long as you don’t put it anywhere in their way.
Most DNOs make it a condition on the contract with the customer that a sparks is there when they move supply.
SP just leave an isolator and a space and as long as it looks like you have a plan the rest is up to you!

Great, thanks! Sage advice as ever.

Remember you must supply the tails from the Henley's to the meter.
