Distance between meter and cut out

[mesbest]

My main cut out and meter is in a small cupboard above a kitchen sink. The CU is in the utility room next door. The tails are approx 2 meters long. The DNO has said there is not enough room for a smart meter in the small cupboard.
Is it allowable to fit the smart meter next to the CU in the utility room as long as the tails do not exceed 3m? Or is there a max allowable distance from the cutout to the meter? I can't seem to find any regulations that apply.

Looks like you have a good excuse to not have a smart meter!

This will be governed by the policies of the individual metering companies.

But why would you want to have a smart meter?

I have solar panels with a feed-in tarrif. Without a smart meter I only get paid for 50% of the energy the panels produce, rather than paid for the energy they actually feed back to the grid.
