Thanks @agentgeorge. I think all fixed tariffs are getting a 3.5p reduction. But, from what I see on Reddit, Octopus Go and Intelligent Go varaible users are getting only about 1.8p discount. I was on Octopus Variable Go until last week at 8.5p. So, just wanted to compare what the reduced rates would be with respect to the 9.5p fixed I would be on from 1st April.

- @chandykris In the case of Cosy (unfixed), the cheapest tariff has gone down by a little less than 1.5 pence per unit - as per my posting a little downstream of here yesterday. Regards, Toodles.

So you stayed on the variable (non-fixed) Cosy? I know you were considering the fixed Cosy variant when it came out.

Solar generation completely offsets ASHP usage annually. We no longer burn ~1600L of kerosene annually.
@old_scientist I thought that the difference in unit charge for the fixed rate versus the £25 ‘bail out’ charge for early cancellation would do me no favours for the amount I use as I had hoped (!) to be swapping to IOF for the spring! Oh, where is that crystal ball when you need it? Regrets, I have a few, Toodles.

I am now baffled. I am currently on Octopus Go (non intelligent). According to my 'letter from Greg' my prices will go down to 28.604/6.5 on 1st April, so far so good.
I am looking at getting a car charger that is compatible with IOG. However if I switch to IOG my prices, after 1st April, will according to their helpdesk, be 34.32/8.00, a rather large increase whereas IOG is normally cheaper than OG.
I presume this is because I am currently on variable pricing (varied each quarter) and they will transfer me to fixed pricing. I have asked for clarification but its making no sense.

@jamespa That seems to be the case. As gas prices are volatile at the moment, to fix for 12 months for peace of mind, we are having to pay a slightly higher price. I guess, if I had stayed on Octopus Go variable, mine would have dropped to 6.5p too. I decided to fix instead and pay 9.5p for Octopus Go fixed for 12 months. Hopefully, that should cover our peak usage over the winter with our HP.

I was wit Eon Next for export and import. I was very disappointed with the drop and restriction for their export tariff. I was getting fixed 16.5p/KW. They dropped that to 6p/Kw now. They also will not let me have the higher rate export tariff at Eon next if I am on any "time off" tariff. I belive Octopus made that change too. I am just changing to Fuse energy my export 13p/kw they are the only one with this no strings export tarrif with this export rate. Since my EV tariff is really good at Eon next 6 hours 5.99p/kw i don't want to leave them.

@andris The situation continues to evolve and develop; notwithstanding the geopolitical fluctuations and frightening risk of huge increases in supply prices along with possible energy shortages, the whole world is in a perilous place just now.
Would I be right in thinking that EV tariffs came about when battery capacity made it possible for subscribers to ‘download’ perhaps 30 kwh’s or more from the grid during the period of lowest demand? With home battery capacities reaching similar figures, I wonder if any of the suppliers, (Octopus, I’m looking at you in particular!) might be considering extending the EV tariff to include large domestic energy storage systems? Just wishful thinking I suspect, but, one can dream. Regards, Toodles.

@andris I am on Octopus Go and also Outgoing Octopus. I see on the Octopus website where they have conflicting information. They have an image that says Octopus Go is not compatible with any export tariff (including the 4p SEG which even customers who don't have an Octopus import account can sign-up too). But the details page says Outgoing Octopus is compatible with Octopus Go tariff. So, worth speaking to them if that helps.
Posted by: @andris. I belive Octopus made that change too
@toodles It would be good if Octopus designd a tariff for customers who have all types of renewable tech at home. They have heat pump, EV or solar/battery specific, but not one that combines all into a consolidated tariff. I have some thoughts but not sure how to feedback to Octopus.

Wow that is good to know! Thanks for sharing.
However in my case the import tarrif and the time of cheep EV time.is better with Eon Next. It makes a big saving with my usage. Thankfully my house holds the heat really well so I only ever need to heat during the time Ev tarrifs is on. I need the cheapest possible tariff so I can do all heating hot water dishwasher etc in that time.
Here is a little summary Octopus GO v. Eon Next drive
-Night rate 36% cheaper
- 20% Longer EV time
- Day rate 14% cheaper
- Standing charge is 5p/ day cheaper

That's amazing. Would love to just run our heat pump during the off-peak hours! But despite living in a relatively new build we do have to run our heat pump 24*7, albeit it only ticks along at low levels the whole time. On average it consumed about 20 kWh a day this January with a COP of 4 including heating and DHW.
