My script showed that we had built up around £450 of credit over usage since we switched in late August. So I have reduced our direct debit by roughly £50 per month. I'm assuming our usage over the winter will be a bit higher, particularly since I didn't commute for 6 weeks during Sept-Nov. So in the absence of any billing from Octopus, I can at least avoid us going excessively into credit or debit. I would expect us to arrive at March roughly at break-even. We'd potentially go back into credit over the summer, due to having solar panels, or I could reduce it further.
There are no missing samples in the dataset, so I can't verify Octopus' claim that there are missing data.
Phoned Octopus today as still no billing for electricity and still no resolution on the inaccurate smart meter clock (now 2:45 off as of last time I checked it).
On billing, they're saying the switch-over meter reading still hasn't been agreed. Which is odd, since we had a final bill from EDF just weeks after the switch.
On the smart meter issue, they've done nothing since October. The cheap rate starts at 9:45pm now due to the clock inaccuracy. By this summer, we're going to be getting solar output during the 5p rate.
So a few days ago my OH emailed them to point out how long this has taken, and today we received a bill finally, with Octopus Go fully applied from 29th August. No missing readings, and it all tallies up with what I had calculated myself. Because I reduced the DD, rather than being £500 or so in credit we're about £235 in credit. I have reduced it by a further £75 from next month as our gas and electricity usage will be much lower over the summer and we don't really need to build up credit ahead of next winter.
Our average price per KWh is about 11.5p, which given the current energy market, is a very good deal.
On the smart meter timing issue, the guy who replied is asking for an explanation of the issue. This will be about the 5th time we've had to explain what's going on, and why it's an issue, over 7 months, despite having been told back in October they'd be looking at how it can be fixed. Shambolic.
