Ever since I had SM's installed, the indoor display has never provided
a sensible number for the Estimated Cost.

While I was with e.on (who fitted them) they always gave an accurate
instantaneous cost and accurate hourly/daily/weekly/monthly/annual
graphs on the IHD.

It had always just shown the
total cost since it was first installed, adding the cost each month -
not taking into account the direct debits I was paying each month
against my account.

Mine didn't claim to show an amount owing, so didn't build up throughout
the month then drop to zero when the DD was paid.

Once I moved to ScotPower, it kept the kWh readings, but priced them at
0p, would be better instead if it simply didn't display costs, rather
than showing 0.00
