Being Green (er)...and being ripped off by the power co.

It's startling to note the drop in water usage in the first water bill we have received after installing our new front load washing machine.
Our average daily water usage has dropped by around 1/3 (35.9% down from the last bill and 32.8% from the same period last year)
We have also noted a slight drop in power consumption.

We are now policing the potholes shower times, encouraging them to use a 4 minute timer, and encouraging them to switch off lights when they leave a room, along with turning off more appliances at the wall and not letting the computers run overnight.

And then....
Another win we have had, which should cut our power bill a bit is with the energy co. Some time ago they changed the meters in our meter box to "time of day" meters (so called "smart metering"), that record power used according to the time of day and we are billed according to what time the power was used at either peak, shoulder or off peak rates...
Fair enough I thought, until I recently started to scrutinise the bills looking for ways to reduce our consumption / cost. The off peak hot water (controlled by them remotely) was being billed at "off peak" for the bulk of its use, but when the second "boost" element cut in during the day we were being billed at "shoulder" or "peak" rates..
I checked with our "sparky", who lives on the corner, to see if he could put a switch in the meter box to isolate the boost element circuit, at least that way I could stop the high power usage during the peak period, but alas I would have to ring the energy co. because the existing master switch was sealed....
Then I checked the energy co. website and it implied that when they change you to "smart metering" your off peak hot water should not be affected..hmmmmm....so, as I was previously only ever being charged off peak rates for boosted hot water during the day, I rang 'em...
Two weeks later they got back to me... "yes, you have been overcharged for your hot water"..turns out, not only were they charging me full rates for the "boost" usage during the day, the smart metering "off peak rate" they were charging for the hot water was dearer than what it should have been (should have remained on "off peak 1")...the end result is they had to go back to the date they changed the meters and reissue every bill at the correct rates...so now we have a big chunk of our latest bill credited back....cool!
So...check your bills if they have changed you to the new fangled metering!!!! it could pay off!
