Octopus Go v Octopus Agile.

Octopus Go versus Octopus Agile is one of the most popular topics linked to Octopus Energy smart tariffs.  You’ll need a smart meter to access both of these Octopus Energy tariffs but once you’re ready to go and leave your interim tariff the big question is Octopus Go or Octopus Agile?

UPDATE: I currently wouldn’t recommend Octopus Agile unless you have solar energy to export to the national grid as wholesale energy prices have gone through the roof. Instead, compare Octopus Go or Go Faster to Intelligent Octopus for EV charging. If you have solar panels Octopus has amazing export prices with Octopus Agile outgoing. You don’t need to be on the standard Octopus Agile tariff to take advantage of the export!!! The export rates per kWh are fantastic at the moment on Agile. You can mix this outgoing tariff with anything other than Octopus Go / Go Faster!! Thank you Octopus Energy!

What’s right for you – Octopus Go v Octopus Agile.

No one can tell you which Octopus smart tariff is right for you. So many influencers seem to hold the answer but they aren’t you and they don’t know how and when you consume energy and your personal preference to investing time in order to save money or access greener energy.

The key thing to remember is that this is all fairly new territory and whatever you do, whichever Octopus tariff you choose you’re making a greener choice that is right for you at this moment in time.

Here’s some information that may help you make up your mind on your Octopus Energy smart tariff.

The Octopus Energy Agile tariff allows you to use energy when consumption is low bringing down prices to a minimum, sometimes even free. Shift your energy use outside the 4-7 pm peak to save money and use cleaner, greener energy when there is less demand on the grid. Plus “plunge” pricing when wholesale prices go negative could even pay you to use energy!

The statement is slightly outdated as plunge prices are currently few and far between. Energy prices have skyrocketed and as agile follows the wholesale energy prices it is going to remain high for some time but there are still energy price drops during the day as they change every 30 minutes depending on demand.

Octopus Go offers a very attractive 4 hours of electricity at 5p per kWh between 00.30 and 04.30hrs. You can keep the running costs of your EV down but you can also schedule large home appliances to run during these times, such as your washing machine and dishwasher. When the peak rate per kWh is 24.45p this will make a massive saving on your energy bill!

How much does Octopus Agile cost?

The Octopus agile price per kWh of electricity changes every 30 minutes.  The idea is you shift your energy usage to a time when there is less demand on the national grid. The prices are displayed the day before on the Octopus Energy website. You can find out more information about the Agile tariff on the Octopus website.

Octopus Agile is usually much more expensive than Go between 4 pm to 7 pm peak period but cheaper than Go from 04:30 am to 4 pm. At the moment, however, this isn’t the case. This is due in part I believe to the lack of wind. Prices have been consistently high on Octopus Agile for the last few months.

I have highlighted tomorrow’s prices to give you an example.

Octopus Agile Rates 2021

National average cost per kWh on the Agile tariff on Sunday 26th September 2021

Min: 25.7p (04.30)

Max: 35.0p (09.00)

Average: 31.0p

Av. Excluding Peak times 30.5p

Cheapest 4hrs: 26.4p

Peak Time 1600 – 1900: 35.0p

Thanks to @energystatsuk for the daily figures.

As you can see the average price is 31.0p per kWh (it was 32.2p today /  Saturday so it’s gone down) and the standing charge is 21p a day. (25/09/2021) If you compare this to the Octopus Go tariff then Go would be the winning tariff for charging your EV. However, when you look at prices you have to look at the average for the year! Prices this month on Agile have been higher than those seen commonly in 2020.

On Twitter, there is quite some debate around sticking with the Octopus Agile tariff or moving over to Octopus Go. Quite a few are moving to Octopus Go BUT and this is a big BUT they will be back!! This is the great thing about Octopus Energy’s smart tariffs. You can switch between the two. If you switch away from Octopus Agile you can’t switch back for 30 days but that’s fair enough! You can chop at changes tariffs though as the weather or personal circumstances or needs change.

So the winning Octopus Smart tariff is……

I won’t take away the last 2 minutes of your life without giving you my opinion. 😆 It’s all very personal to your needs but if you want to plug your EV in and forget about it Octopus Go is more likely to be the one for you! You can also make the most of the 4 hours of very cheap energy to get your house in order with washing machine whizzing and dishwashers running. If you want to play around with half-hourly energy prices and use energy when there’s less demand on the grid you may well be on Team Agile BUT Octopus Go would be cheaper for charging your EV and getting the most out of cheap energy which is like finding a needle in a haystack at the moment!

Even though Octopus Go is currently cheaper than Octopus Agile half-hourly pricing is, without doubt, the way forward to even out our energy consumption and reduce the massive peaks in use on the national grid.  This is a good read on half-hourly pricing and net-zero.

Update: Octopus Agile is sadly way too expensive at the moment. This is due to wholesale energy prices. Most people still are on this tariff are sticking with it as they have solar panels and export excess energy on Octopus Agile Outgoing. Let’s hope things change in the spring!

If you don’t own an EV and are using Octopus Agile as an alternative to a standard Octopus tariff it’s still a great way to focus your mind on shifting your energy use BUT I wouldn’t recommend switching to Octopus Agile right now. At the moment the average daily rate has gone up but it does depend on how flexible you can be with your energy use. This tariff is fantastic for helping to make the grid greener BUT pricing has been consistently high for the last few months!! We just need some more wind to bring the cost and for the energy crisis be to over!

So whenever you discover this post if you are asking yourself Octopus Go versus Octopus Agile remember you are asking yourself this question as you are not sticking to the norm and going with a standard tariff. Standard tariffs at the moment are ridiculously high! Switching to a smart tariff at least gives you the freedom to try and bring your overall energy bill down. You may be trying to be greener or save money or both but it’s all a learning curve and one we have to do to give the planet a better future!!

You can read my full review on the Octopus Agile tariff HERE and the Octopus Go and Go Faster tariffs HERE. 💕 I’d also suggest you look at Intelligent Octopus which is a beta tariff BUT I can see it becoming more consideration for those looking at Octopus Go. The next post I think will have to be Intelligent Octopus v Octopus Go!!

Here are a few of the reasons Agile prices have been high at the moment. I have written a blog post that might prove helpful.

Octopus Watch App

I would strongly suggest looking at the Octopus Watch app. Watch refers to keep an eye on something rather than needing a smartwatch to access it!! 😁

I would say this is one of the most useful apps to consider if you are switching to the Octopus Energy Agile tariff. This app allows you to download up to 3 months of historical data.  You can use it to set Agile pricing alerts and interact with Siri. It’s a good app but the fun really starts in the subscription version.

(Find this app at google play)

(find this app in the app store here) (find this app on the Amazon store)

Octopus Watch with Subscription.
(£1.99 + £7.99 per year/£0.99 per month)

This is really if you want to help shift your usage to make energy greener.  You can set alerts so you know when the lowest carbon period is.  It really depends on how much you want to play around with your energy usage and shift. The predictive reports are great too. If you want to plan and work out which day would be best to charge your car or do your weekly wash then the predictive option helps a lot. Of course, these energy prices are just predicted. However, they have shown to be 90% accurate, which is good enough for me.  Here is their website.
