DIN rail kWh meters

This is an extension of the consumer unit question

http://communities.theiet.org/discussions/viewtopic/348/22833

Has anybody any experience of DIN rail mounting kWh meters that can be installed in a consumer unit? They are an uncommon feature in most homes but they can be incredibly useful devices as they enable electricity consumption to be identified on a circuit by circuit basis. This provides much useful information on which appliances are and are not consuming a significant amount of electricity therefore helping to identify where potential savings can be made. More cynically, they could help reduce disputes in families who is responsible for big electric bills.

I am aware that these meters are available in both MID approved and non-approved versions although MID approval is not required for in-home only use. Some meters are available with a MODBUS output.

I doubt DIN rail mountable kWh meters are mountable to most standard domestic consumer units, as their designed usually to have OCPDs connected via a busbar - and not a DIN rail. But that doesn't mean some manufacturers don't manufacture specialist distribution boards for both mounting types - but i havent come across them myself to be honest.

On a side note, i've had to design electrical systems in homes where heating circuits only were required to be metered via DIN rail mounted kWh meters (the landlord had a peculiar agreement with its tenants resulting in this needing to be done). We essentially just mounted a small DIN rail box for the kWh meter(s) right next to the distribution board.
