British Gas EV tariff

sabelu

I have the above with BG allowing me off peak energy from midnight to 5am.
My energy usage for March prior to this was weighted very heavily towards off peak, see below


However after we changed the clocks my usage has changed to more of a balance, see below, I'm using electricity in the same volumes and same times so both graphs should be very similar.



I have to ask the only change  is the clocks change and looks like my first hour of charge is now at peak rate.
Has anyone else had this?

Are these actual bills or just feedback of data?  If it's the latter, just make sure that BG recalculate the actual bills to take the clock change into account.  They have your half-hourly data so that's easy enough to do.

I'm actually trying to get them to agree that based on nothing but the clocks changed they need to sense check their illustration, I'm not saying I'm being overcharged but this doesn't give me confidence. I'm also really now only confident to use the overnight tariff from 1am until 5am rather than midnight.

Sorry didn't answer your question they are their stats from their app

I don't know if this helps but after BG updated their systems last year, during BST my cheap tariff times are from 2300hrs to 0400hrs. Maybe try it.

We have had a similar experience. The British Gas EV 12 Tariff states it is between midnight and 5am, and we use most of our electricity during those hours (charge up car, Tesla Powerwall and run appliances). With our solar panels starting to produce significantly as well, our peak usage in March was down to < 12% of the total and has been 20-25% during the winter months. When checking our April usage a few days ago, I was staggered to find peak usage up to 55% despite doing nothing different. Initially we thought it might be to do with the change to BST, but our % peak usage actually increased from the 1st April, not the 30th March as you might expect if it was just this. I double checked it wasn't an issue with our own timers or the Powerwall time setting - it is not. I have tried 3 times now to address this with BG 'support' and each time received nonsensical answers which failed to address the information I provided. A couple of days ago I reset everything to charge/run between 01:00 and 06:00 and guess what - my usage is now predominantly off peak again. I'm waiting for a couple more days of data, then will be raising a formal complaint, backed up with the data from my Powerwall app which shows exactly when I'm drawing electricity from the grid day by day. Based on previous issues with BG support (it took best part of a year to get them to understand that the clock on our ancient electric meter was not operating correctly so we had no idea when off peak actually was for us!) I'm bracing for a long haul. Out of interest here is BG's own description of the EV 12 tariff 'Charge your car for less overnight (12am-5am every day)'. No mention of resetting for the clock change.
