When are you going fully electric?

Thank you for the detailed reply. As for being locked in, embarrasingly I've not changed supplier or tariff with EDF since I moved in 2007. Other than talking to people about roughly what they were paying and mine seemed lower so didn't ever look at it. I need to look through my bills as you say and work out what I'm using at peak.
Unless your household usage is really low, at 19p there probably wouldn’t be much in it vs a 30/7.5p rate. But as above it just depends on how much hour household usage is, when working it out if suggest doing it on the basis of all your current usage (from your bills) is on the day rate and 90% of your proposed EV usage. Sure some of that household usage will be in the night rate but it’s hard to estimate and we don’t know your appetite for running the washing machine overnight etc. Likewise pre-heating the car will always be on the day rate and you may need to charge it outside of overnight ours on the odd occasion.
For the Kona I’d suggest 4 miles per KWH, slightly less for the Nero. For bigger stuff like the ID.4 or Enyak then 3 miles per kWh. For the dual motor cars or those which are known for being thirsty then knock that down a bit more. Then add on 10% for charging losses.
You should be looking at realistic numbers then.
It’s actually cheaper for me to stick on the 20p rate I am paying. Once that rate ends then in current priced Octopus Go is way better. In the mean time if you don’t have a smart meter you need to get one so when you do change, you are ready to go.
I’d leave the gas where it is and when it expires, go onto the standard variable tariff (all current fixed rates are horrendous). You can have it with different suppliers without any issues.
Thanks, just looking at my bill my normal annual consumption is estimated at 3600kwh and I'd use that just about all in peak hours and we don't run anything when we are asleep apart from devices on standby. The usual stuff. So probably best to just stay on the 19p then and work it all out from there for now.
A bit of quick man maths from me based on Kona or Model 3 and your 16,000 miles:
16,000 miles / 4 miles per kWh + 10% losses = 4,400 kWh plus 3,600 kwh household usage. 8,000 kwh X 19p = £1,520
or (based on 90% EV use done in cheap window)
4440 kWh X 30p = £1,332 and 3960Kwh X 7.5p = £297
Total cost = £1,629
So based on 16k and your current rates, I wouldn't swap either. You are not far from the cross over point though so if you find you are doing more miles than expected, its worth revisiting that. As soon as that tariff comes to an end though you want to be moving over (based on that price I'd assume late this summer), if not before if there is word that the Go price is going up.

Furthering the man maths, take into account a base load of something like 150w 24/7/365 then between the hours of 00:00 and 04:30 that would be 0.675kWh per day or about 250kWh in a year, so about £47 at 19p, vs. £18.50 at 7.5p.
So there really isn't a great deal in it at all, even the standing charge now has a reasonable impact on the bills, as you say once the cheap tariff ends.
on the used market values, feb autotrader update -
interesting that, counter intuitively ? (running cost, improving range) the ev's are not showing higher price gains(better residuals) versus ice.
maybe down to incoming, new, manufacturer prioritized, ev supply ? they need to restrict new supply - if only they didn't have carbon tax constraints.
Kicked off my move to Octopus Go today. 30.61p / 7.5p. 24.11 standing charge.
Not great but the day rate is only 2p or so over the cap. Worked out I need to use 3.5% of my electricity in the cheap window for it to make sense.
Also covers me from any increase on the cap in Sept.
It's going to take a few weeks to move, so I hope the price doesn't change before April.

I'm still a bit unsure how to work out whether it's worth trying to get on Octopus Go for my EV or just get a price cap. My mileage is going to be very low, and I unfortunately don't know our annual usage as my partner dealt with the bills at her house (before we sold it). It's a Kona so might as well work on 4mi/kWh. My annual mileage that I'll have to do is something like 1200, and then anything else on top is leisure or shopping trips etc. So maybe up to 4000 as a middle ground so I'll need about 1000kWh. That means I'd almost certainly be able to do all my required charging in the cheap window, it's just a case of knowing what the rest of the house usage will be.
Octopus showing 32.49p/day, 7.5p/night, 23.5p standing charge but we're still in March and I won't be moving until at least April.

Yep - exactly my thoughts. I switched to Oct Go a couple of weeks ago and it starts today.
If you are on the normal capped rate, Go is a bit of a no brainer at the moment (leave the gas where it is on the capped rate).
As the person said above you only need to have a small % of your consumption in the cheap period for it to work out.
It’s only a different conversation for those on older tariffs at like 20p/kWh.
The issue is we live with parents at the moment, and have been for the last few months so comparisons are going to be hard, plus we won't get into the house until at least April so it's very much up in the air.
I actually just found an old bill from when I lived on my own a couple of years ago with an annual electric usage of 1100kWh, so I imagine 2.5x that living with partner plus some WFH now, then add on my car usage. We're reasonably frugal with electric usage, will have LED lights everywhere, and could try and move washing machine to the night rate to save a little more etc.
I would say with almost any electric car usage you are better on go if you are not locked into historical rates.
The way to look at is you’ll be paying 2p more on about 3000kwh (pretty typical use these days) but saving about 20p on 1000+ kWh for 4000 miles.
2p x 3000kwh = £60
20p x 1000kwh = £200
So it’s a £140 net saving, the lower your household use the bigger the saving, same goes for the car use, the bigger the use, the bigger the saving.
Personally, if the go rates are still 30p/7.5p when you move in, I’d switch on day one.

If you can afford it Go and a home battery that you charge during the cheap window really unlocks low bills.
Thanks, I've just knocked up a spreadsheet to work it all out so I can modify the numbers as and when we get an idea of what they'd be once we actually have a move date.
On current rates it shows I'd have to actually run a minimum of 2500 miles just to save on the day and night rate vs price cap, though I go do as low as 600 miles to still save overall due to standing charge difference!

I wish I could get my electricity usage that low, think I'm hitting 650kWh a month with no heating. So only ovens, washing machine, dishwasher, tumble dryer, kettle, shower etc. That's before I add on the car charging.
Literally starting to wonder if the neighbours have wired in..

650/month is some serious electric usage. Is that consistent throughout the year?
For context, the average U.K. household usage is under 300kwh/month on a dual fuel.
The difference between winter and summer for me is pretty negligible with all LED lighting. The only other difference is central heating pumps, again they are pretty low usage.
