@toodles yes, EV is key requirement for IOG. Standard Go and Cosy offer nice options for non-ev users and just a question of looking at own usage and kit to see what will work best.
I suspect we'll see Agile have some nice cheap periods again this summer - so may suit some people. My average on Agile last year was around 12p but required a bit of faff - as previously discussed - even using Wonderwatt I still had to daily tweak.

@tim441 One can never quite trust these AI thingies to do the job properly can one? They need to be kept ‘on their toes’ I feel!😉 Toodles.

Wowee! Agile have one half-hour at under 15 pence per KWh tomorrow! Light at the end of the tunnel or just a glimmer of hope!? Regards, Toodles.

Now that the heating season is almost over, have any of you switched from Octopus Cosy tariff to Octopus Go yet?
We are using less than 5 kWh for the heat pump now and a good chunk of that is just for hot water. So, I switched over today to the Go tariff. It will save for charging the EV, and also with solar generating decent amount every day, the batteries should last longer. Well, that's the hypothesis. Our average import rate is around 14 pence, so hopefully starting today it should be around 8.5 pence. And when the heating season is back on, hoping to just switch back to Octopus Cosy.

@chandykris We were on Cosy until 1st. April and then switched to Intelligent Octopus Flux (no EV tariff available to us) It is touch and go with heat pump use and daily fluctuations from winter to spring weather still lingering; however, the import rate is well above Cosy (based on only using the grid power during the 8 cheapest hours per day) but the export rate is on parity for 21 hours per day. Three hours a day permits export (from battery and / or solar) @ ~ 30 pence per kWh. During the summer, we should exceed import needs with a fair amount of export - and help to take the peak demand out of the grid. Come the autumn, I’ll be checking if Cosy is still available… Regards, Toodles.

@toodles That's my idea as well. We don't have a compatible EV charger or the battery, so Go is the main option. But, from my analysis of last year usage, we should save a decent chunk for the next 6 months by switching to Go from Cosy. Only time will tell whether that's the reality.

@chandykris And one other consideration is the lower daily standing charge of 43.94 pence for IOF. I’ll do a little progress report when we find ourselves to be in the merry month of May.😏 Toodles.

@chandykris Yes, if you are able to last the day on solar/battery then Go is going to work out better than Cosy. Obviously the trick is timing the switch.
April looks like being a month of two halves. First half was amazingly sunny and warm (maybe you should have switched at the start of the month?), whereas the second half is looking more like the depths of winter (there were reports of snow on the hills not far from us today).
We have solar but don't have batteries, and switched from Cosy to Agile at the end of March which is looking like the right decision for us so far.
Key for you now will be are you able to see out the day on your batteries now it's turned colder and the heating is likely back on. Our current Agile import prices are not dissimilar to the cheap Cosy slots, and Agile is almost always cheaper than Cosy day rate and peak rate pricing.

Solar generation completely offsets ASHP usage annually. We no longer burn ~1600L of kerosene annually.
@old_scientist Can but hope that Met Office et al are wrong; April is looking fairly promising when compared to Gloomy 2024!

@broadsman As requested:
The first weeks results are detailed in the extract from the bill; as you will see, there are just the two rates, standard and peak. Regards, Toodles.
