We’ve switched to E.ON Next Drive. Could have gone to Drive Smart (6.5p), but might wait until some of the app issues are ironed out. It doesn’t yet support controlling the CP. So we basically use the Hypervolt scheduling to 12am-6am, and switch to “Plug & Charge” if we need an urgent charge.

7.5p between 12am-6am. Fortunately we have a home battery, so now fully charge that every night. That gives us some larger energy cost savings throughout the day that we couldn’t get at OVO.

We’ve liked the flexibility of CA, but not at 14p and some very useless plans. Can cope with the odd daytime charge at 28p as the 7.5p overnight EV and home battery far outweighs CA. In fact the move has been beneficial in that respect.

Tend to agree other suppliers may follow OVO with cost changes, but there are no exit costs at E.ON, and the switch was very easy. 5 days from submitting switch, and 2 days to sort meter registration and tariff move. So no bother to repeat if the market dictates that.

I’ve done the same but with Octopus instead. Switched to them for both electricity and gas. Once completed, I switched to Intelligent Octopus Go which guarantees 6 hours of cheap (7p) electricity every night, plus they open up other 7p slots when there’s a surplus of green energy. I have solar panels and a battery, so like you there’s the added bonus of charging the battery and holding it there till 5.30am. Solar is keeping it fairly well charged during the day, even in mid November, and it’s lasting till fairly late in the evening. Then it charges up again at 11.30pm.

I’ve also installed Predbat on Home Assistant, which takes a bit of research and work to get working, but that takes into account the predicted solar energy, average house load, and cheaper time slots to plan when to change the inverter settings to charge the batteries and when to switch back to normal use. If the car’s plugged in it assumes this will charge during the cheaper slots too. It then controls the inverter. It’s very clever and will likely save a bit more money.

The other benefits are the excellent SEG rate of 15p/kWh, which I’m in the process of transferring to from British Gas (3p/kWh) and the gas tracker which is currently running at about 4.6p/kWh.

I see Ovo have now announced a battery booster package which allows charging the battery at 10p/kWh. Had this been advertised a month ago, it may have tempted me to stay with them because that would have reduced the costs, especially between October and March. I think they missed a trick here as I’m sure many EV owners also have solar panels and batteries.

@FatOldSun The SEG rates at E.ON were at 16.5p but have now gone down to 6p for my situation. My understanding is that wholesale rates are often quite low even less than 10p, so I’m not surprised SEG rates over 10p have their days numbered.

Hey ​@KHebb 

 

As one of our volunteers has already mentioned above, initial emails regarding this were sent out around 24 September, if you could double check your spam folder just in case it’s slipped in there? The communications have already been issued as our volunteers have mentioned so you should already have receive notice of this change.

No - I can’t find anything in the junk folder either

@KHebb that’s strange, maybe there was a technical error with either OVO or your email provider at the time the emails were sent.

Given the new changes which make it a lot more expensive, does this waive the early exit fees when leaving?

Hi ​@Kerrylou24 ,

Long story short… No. You had that chance for over a month from late September and the exit fee waiver expired on the 4th November. If you didn’t choose to leave by then, no promises are made about the fee waiver. You’ve already had six weeks prior to the switch PLUS a further 13 days on top… So the real question would be where have you been all that time?

It doesn’t affect your main contract, so you can’t use that clause either.

Thanks for that ​@Blastoise186 

Unfortunately I missed it as was too busy with work/family life! So I guess It's my own fault and will be paying through the nose now for the next 12 months seeing as I do about 15,000 EV miles per annum

If it’s any small consolation, as OVO announced this just after the quarterly price cap changes, if you were already fixed into some sort of deal, then even with 14p per kWh charging costs, most of the other popular EV tariffs had probably already increased their regular usage unit rates (and standing charges) meaning that unless you could engage in some fairly high level load shifting to mostly overnight usage for all your appliances, over the course of a year you’d probably be within £20 or £30 total cost anyway.

I know when I compared staying with OVO (14p anytime EV and 23p regular usage) or moving to something like Intelligent Octopus Go (7p semi flexible overnight EV and 31p regular daytime usage) because their regular daytime rates have gone up to 8p per unit higher than i’m currently on, I wouldn’t have been much better off moving anyway, so i’m just leaving it until my current fixed deal ends and then reassessing what to do based on whatever prices are looking like next year.

There was a recent article from Electrifying that did a comparison between the top EV tariffs → https://www.electrifying.com/blog/knowledge-hub/best-ev-electricity-tariffs-the-top-energy-tariffs-for-your-electric-car

The results only go to show how you should do your own calculations based on your usage pattern. They concluded that EDF’s Go Electric worked out the cheapest, closely followed by Octopus.
However, using a spreadsheet, I put in all the numbers for the various suppliers and [yes] for my usage pattern EDF Go Electric was cheaper by £29 per annum. The second one was OVO Charge Anytime, but with the advantage of being able to charge at any time of the day.

My wife and I are retired and have 2 EVs, so OVO still makes the most sense for us, and is the most flexible. We’re also not interested in doing our washing, etc., during the midnight hours.
I have no use for the public charging packages, so cannot comment there, but the changes have certainly upset a lot of people. I note that this thread currently has 309 dislikes and 0 likes.
£29 per annum savings are neither here nor there, and next week who knows if other suppliers will put up their prices.

I also did the maths. And it looked like it worked. Until I realised the £100 cap. And now my last three bills have capped out at £100 credits.  So after that I am paying full price for a chuck of my charging.  
 

i cannot move to a pack as I do more than the stated pack miles. 
 

I will now look at other suppliers again

@HangNail999 thanks for sharing this article and the ways in which Charge Anytime works for you personally. I’m glad it’s worked out for you.

 

And ​@Bobbych - sorry that the same can’t be said for yourself - I hope if you do move you’ll find the best possible option, and maybe HangNail999’s article will help you make your choice.

You must be doing over 2,800 miles a month to hit the £100 limit.

If you have solar panels and house batteries, that tips it in Octopus’ favour. When a car is plugged in during the day, cheap half hour slots (7p) appear through the day even if the car is fully charged, and this gives the whole house cheap electricity. The batteries recharge at 7p and when the cheap slot ends, the house uses the battery storage. With an export tariff of 15p, even in the summer it will make sense to charge up the batteries and cars at 7p instead of from solar, and then the excess solar can go back to the grid at 15p. What you lose is some flexibility in charging when you want, you have to rely on the slots provided by Octopus, but this hasn’t been an issue for us so far.

One caveat with Octopus is that they’ll soon introduce a cap of 6 hours of cheap EV charging per 24 hours. So this wouldn’t work for people who do long journeys every day and need a full charge overnight, since anything over the 6 hours will be charged at the standard rate.

For comparison, the electricity charge for January last year with Ovo, including standing charge and Charge Anytime credit, was £150. My Octopus electricity bill for this January is £90.

Question: Do you have home automation to only have the battery charging during the discount slots otherwise it would be using the non-discount rate.

Yes, I have a Raspberry Pi running Home Assistant, and in there I have software called Predbat which decides exactly when to charge/discharge the battery based on many factors such as Octopus time slots, EV charging status, solar forecast, and historical power usage. If the statistics are to be believed, this is saving anything from 20p to £2 per day.

Thanks. Its worth knowing that because not everyone has a home automation system (HA in this case) but doing that gives more options.

Indeed, it’s particularly useful when, like me, the EV charger was installed without the necessary CT clamps to “hide” the charger from the house load. Otherwise, it dumps the house battery into the car. This also requires an integration with the inverter API, and a method to control it. This is also relevant to Ovo Charge Anytime in terms of preventing battery discharging into the car, but to a much lesser extent regarding charging the batteries since there are no cheap slots for that with Ovo.

Just as a note, because you have sidestepped the issue but there may be others reading this, if you want to avoid the battery discharging into the car you need to take the feed for the car charger before the battery CT clamp. This means the battery doesn't see the load going to the charger and doesn't try to supply it.

If done from the outset the output of the meter goes into Henley blocks, one feed goes to the consumer unit and has the battery CT clamp on it and the other feed goes to the car charger perhaps with a sub CU. The downside is the battery system no longer sees the entire feed for the house and some people use that for monitoring and providing data for the whole house usage. It also complicates data monitoring if you have solar.
