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?

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 invest 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!

Octopus Agile November version 1 

On the 28 of November 2022 November, version 1 of the Octopus agile tariff was launched.  The new Agile tariff has a cap of £1 per kWh and has an Energy Price Guarantee discount.

The NEW Octopus Go flexible tariff.

Octopus Go offers a very attractive 4 hours of electricity at 12p 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 unit price on Octopus Go is 42.17p per kWh this will make a considerable saving on your energy bill!

The new kid on the block is the Intelligent tariff.  I have been on it for a while but you have to either have a compatible EV or charger. The big draw to this tariff is that it’s 2p less off-peak than Octopus Go at 10p per kWh and you get 6 hours as standard instead of 4.

I average between 17p and 19p a kWh on the intelligent tariff. I use around 55% of my home energy off-peak even though I am home all day. My mileage isn’t massive but I load shift lots in the evening. My peak rate is slightly lower. I am still on the old fixed rate of 7.5p per kWh off-peak and 40.04p per kWh at peak.

How much does Octopus Agile cost?

The Octopus agile price per kWh of electricity changes every 30 minutes.  The idea is that 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.

Octopus Agile tariff price on Tuesday 6th December 2022 

This is the November version 1 of the Agile tariff.

Min: 34.0p per kWh (00.00)

Max: 81.6p per kWh (16.30)

Average: 51.6p per kWh.

Av. Excluding Peak times: 47.9p per kWh

Cheapest 4hrs: 35.3p per kWh

Peak Time 1600 – 1900: 76.0p per kWh.

Thanks to @energystatsuk for the daily figures.

The average Agile price per kWh is 51.6p. (06/12/2022)

Points to consider;

  • Octopus Agile is capped at £1 per kWh with a daily standing charge of around 47.52p. It could rise very sharply as demand increases in the winter.
  • Octopus Go is 42.17p per kWh with an off-peak rate of 12p per kWh. (depending on your geographical location)
  • The intelligent tariff gives 6 hours off-peak at 10p per kWh
  • You need an EV to be on Octopus Go or Intelligent tariff.
  • You may get less for exporting your excess solar on either of the EV tariffs.

The Agile price should go up and down in price but it could get stuck at around the £1 per kWh peak price. It is a gamble on the amount of wind and demand on the national grid but prices have recently gone negative. This means customers have been paid to use energy.

The Go or Intelligent tariff should bring your average price per kWh down if you load shift.  If you can shift a proportion of your energy use off-peak you could beat the flexible tariff! You just need to get into the habit of turning white goods on late at night or invest in a few cheap timers. Lots of washing machines and dishwashers have timers built in. You have just got to use them!

Here is a quote for Octopus Go on 6th December 2022.  It is a good deal in the current climate for charging off-peak. The Octopus Go tariff is a fixed deal for 12 months. It does not receive a discount under the Energy Price Guarantee.

If you switch away from Octopus Agile you can’t switch back for 30 days but that’s fair enough!

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! However, the intelligent tariff beats this hands down. You just need to have a compatible vehicle or charger.  Load shifting can reduce the average price you pay per kWh quite dramatically.

You need to make the most of the 4 or 6 hours of very cheap energy to get the average price you pay below the EPG. So get the washing machine whizzing and dishwashers running off-peak this will bring down your average price per kWh.

In my opinion, Octopus Agile half-hourly pricing is, without a doubt, the way forward to even out our energy consumption and reduce the massive peaks in use on the national grid.  The intelligent tariff also works in the same way but Octopus take control of your EV charging schedule. If you are happy to try this new tariff you will get 6 hours off-peak instead of 4. Smart tariffs have so much to offer if you can be creative with your energy use. This is a good read on half-hourly pricing and net-zero.

Just a final thought, heat pump owners have been crying out for an off-peak smart tariff and Octopus now has one! If you live in a region where Western Power is your DNO then take a look at the smart heat pump tariff Octopus is currently trialling in your area.

If you own a Tesla or an Ohme Charger (or you are thinking of buying this charger) take a look at this beat EV tariff, Octopus IntelligentIt offers 6 hours of off-peak charging.


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.  This tariff is fantastic for helping to make the grid greener.

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!!

Read both my reviews on the Octopus Agile and the Octopus Go . 💕 I’d also suggest you look at Intelligent Octopus which is a beta tariff.

Octopus Watch App

You can find some great apps and devices using Octopus Energy API.

I would strongly suggest looking at the Octopus Watch app. Watch refers to keeping 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 the smarthound website.

Octopus go review


Energy Price Guarantee

Energy Price Guarantee.

On the 8th of September, the UK government announced measures to help reduce soaring energy bills.  The energy price cap which was due to increase by 81% on the 1st of October 2022 will be replaced by the energy price guarantee. There will also be deductions applied to energy bills that have a high fixed rate per kWh. (clarification is needed)

@sarah_go_green This is how much you will pay per kWh on #energypriceguarantee it’s replaces the #energypricecap from 1/10/22. It is the cheapest #energytariff #gas ♬ original sound – sarah_go_green

How much will you pay if you are on the energy price guarantee? (Stanard variable tariff)

10.3p per kWh for gas.

34p per kWh for electricity.

Standing charges seem to remain unchanged.

The energy price guarantee will remain in place for 2 years.

This is the average price you should expect to pay on the energy price guarantee. It may vary depending on your location.

If you are on a fixed tariff you could also get a discount.

Under the government’s energy price guarantee, you could also get a discount of;

17p per kWh for electricity

4.2 per kWh for gas.

The wording on the .gov website isn’t very clear.

If you’re on a fixed tariff at a higher rate caused by recent energy price rises, your unit prices will be reduced by 17p/kWh for electricity and 4.2p/kWh for gas.

These unit prices have been passed to suppliers to ensure that they are used to calculate bills on time for 1 October.

Energy suppliers will adjust fixed tariffs automatically. Customers on fixed tariffs do not need to take any action to get the benefits of this scheme.

For Octopus Energy I can see this being quite a challenge with smart tariffs but time will tell. It is just a case of waiting to see what happens.

Battery Storage Tariff

Best Octopus battery storage tariff.

Battery storage is an excellent option to help reduce your energy bill. Plus if the lights go off this winter, in the form of a blackout, you will have your own power source. At there moment there is no specific Octopus Energy battery storage tariff.

I have had many questions about battery storage over the last few weeks. People are contemplating the best options for reducing their energy bills and if they can afford the investment there is a good chance they could save some serious money BUT it isn’t as straightforward as it seems. It all depends on your individual situation and the off-peak tariffs available to you.

Octopus Off-peak tariffs for charging battery storage.

If you own an electric vehicle and have a smart meter then you have a variety of options to charge your new battery.  If you are already on an EV tariff such as Octopus Go, Go Faster or the Intelligent tariff you can simply charge your home battery during your off-peak times.  At 7.5p per kWh off-peak the more battery storage you have the better as you can use that cheap energy during the day when prices are high.

In an ideal world, you would use your EV as battery storage but for now, vehicle to grid is limited.

If you don’t have an electric vehicle then sadly you can’t take advantage of these Octopus tariffs. If you have solar panels, however, battery storage would be great for storing excess solar either to use at peak times when no solar is available or for selling back to the grid. I know Octopus Agile is very popular with friends who have solar panels!

@sarah_go_green Battery storage can help #reduceenergybills and #offpeak Octopus tariffs are ideal. We need more #smarttariffs #electrictybill #moneysavingtips #solar ♬ original sound – sarah_go_green

If you don’t have an EV or solar panels then possible Octopus Agile may be an option but it is now capped at a whopping 78p per kWh by Octopus. It does, however, have some protection as it gets a discount under the Energy Price Guarantee. You can read more about this on my Octopus Agile review page.

The Octopus flexible tariff is now looking more attractive since the Energy Price Guarantee. The discount means that even though the day rate is higher than 34p on the Economy 7 version of the Octopus flexible tariff the off-peak rate on average is around 15p per kWh which would be ideal for topping up your battery storage.

Is battery storage worth the investment?

Personally, I think battery storage is worth the investment. I like the idea of having my own backup in case of blackouts. It’s an expensive backup if you can’t get a cheap off-peak rate or you don’t have solar but if you plan to get an EV or solar it may be still a viable option for you.

The interim review from Review of Electricity Market Arrangements may also provide some opportunities for off-peak charging.

Battery storage has to be the way forward for energy security in the UK.

Agile Price Increase

Octopus Agile Price Increase.

Yesterday, at 4 pm the Octopus increased the maximum price you will pay on the Agile tariff. The cap on the Agile tariff increased from 55p per kWh to an eye-watering 78p per kWh.

The Octopus Tracker tariff also increased to a maximum price of 78p per kWh for electricity and a whopping 22p per kWh for gas.

Wholesale energy prices have been increasing at unprecedented levels and this month has been no exception. It isn’t really a surprise to see the maximum price increase but non the less it does feel like a wake-up call!  The energy market seems to be getting a whole lot worse!

@sarah_go_green @Octopus Energy ♬ original sound – sarah_go_green

As ever Greg Jackson, the CEO of Octopus Energy isn’t holding back and has urged the government to take action and keep the energy price cap as it stands.

I feel relieved to be with Octopus even though prices are increasing. They are forward-thinking and even visionary in their approach to energy. The government really needs to take a leaf out of its book and start implementing change!

October 2022 price cap

October 2022 Energy Price Cap.

Today, Ofgem announced the new energy price cap that will come into effect on the 1st of October.  Prices were predictable but still felt like a low blow as autumn quickly approaches.

From the 1st of October 2022, for those on the energy price cap prices will rise by a staggering 80%. This time last year gas was just 3p per kWh but from 1st October this will rise to 14.8p per kWh.  Electricity will rise to 51.9p per kWh from 28.34p per kWh.

My prediction was out by around 1p per kWh for gas, the rest I got on the nose! Martin Lewis has been tweeting the Cornwall Insights prediction for the last few weeks. The question is if a middle-aged housewife can predict these rises and worry about the impacts why can’t the government!!!

I have been worrying about the energy crisis for at least the last year! I couldn’t have predicted they would rise this far. I didn’t envisage Russia would invade Ukraine but someone with some foresight in Whitehall must have! They should have, in my view, made provisions for this!

@sarah_go_green Th #energypricecap has been announced for October 2022. Prices are rising. I’ll share #energyprice information and info #howtosavemoney. #gasprices ♬ original sound – sarah_go_green

Greg Jackson the CEO of Octopus Energy has suggested that the UK public shouldn’t be expected to foot the bill for a war-like situation with Russia and I agree!! I hope in 10 days’ time when the government reconvinces I hope we see some action!!!!

Save money batch cooking

Batch Cooking is a great way to save energy.

I love cooking, but as energy prices rise, I am mindful of how and when I use my oven. Each time it is switched on I add to the amount of kWh I have added to my Octopus Energy bill. At 40p per kWh for electricity, every kWh counts! So I only use the oven when I know it is going to be full.

Batch cooking is a great way of getting the most out of your oven. I grow my own vegetables and love roasting them if I get a glut. Even vegetables that have seen better days get roasted and frozen. I just can’t cope with food waste1!

I make sheets of frozen vegetables by freezing them flat. It is ideal if you want to make lasagna on a day when time is limited or when you need a meal in a hurry.

@sarah_go_green Home made #lasagna. Reduces food waste and uses less energy. #foodwaste #ukmum #costoflivingcrisis #moneysavingtips ♬ original sound – sarah_go_green

It isn’t a new idea. Batch cooking and only using every shelf on the oven is how it used to be as I was growing up. I think we have just all been too comfortable using energy without really considering the consequences.

How much energy does an oven use?

An electric oven uses around 2000 to 2200 watts an hour. So that would add 2kWh to 2.2kWh to my energy bill each use. I am currently paying 40p per kWh (the price cap is 27p per kWh) so that would cost me somewhere between 80p and 96p. It doesn’t sound like a lot but when you add all the extra kWh hours up at the end of the month it really can make a big difference to your energy bill.

I don’t have a gas oven but as I am paying using over 7p per kWh that would obviously work out cheaper.

My favourite method of cooking has to be by slow cooker!! If you don’t have one get one!! They are great for batch cooking curries or stews and for very little effort and money you have great-tasting food!! It is estimated that a slow cooker uses 1.3 kWh over an 8-hour period. So it could cost as little as 52p to cook a delicious meal.

Why get a smart meter?

Why get a smart meter?

This is an update to a previous blog post where my mother asked me the question below. 

My mother asked me this question a month ago. I switched to a smart meter when I moved home. I had to have my old one removed and a new SMETS 2, smart meter, added. My mother, on the other hand, has been reluctant but due to the energy crisis, she is looking at all possible ways to save money on her energy bill.

@sarah_go_green I have a #smartmeter and this month i told my mum to get one too. You should apply NOW as there are savings coming this winter. #moneysavingtips ♬ original sound – sarah_go_green

My answer was quite straightforward, change is coming!!  I took part in an Octopus Energ trial into time-of-use tariffs at the start of 2022. It was a joint trial between Octopus and the National Grid. I was sent a text advising me I could save money if I didn’t use energy on a specific day at a set time. I usually had around 24 hours’ notice. Without question, I did all I could to avoid these times as much as possible so I could get a credit on my energy bill.

Fast forward to winter 2022.

There is an energy crisis where supply looks like it will fall short of demand. Putin is restricting the supply of gas so that the west suffers. In order to stop blackouts, the national grid will have to manage supply somehow. How about using the same strategy as used in the Octopus Energy trial and paying people not to use energy at specific times?

I didn’t specifically guess this would happen but I imagined something very similar would happen. This is why I urged my mother to get one.

Last night an article appeared on BBC business news, Plans to cut energy bills if peak-time use avoided. I hate being right in such circumstances but it was inevitable some action would be needed.

There isn’t much information available yet online as to how the National Grid will implement they say this should be available in the next 2 weeks.

On that basis, my advice would be either to watch this space if you already have a smart meter or apply for one now if it’s something you would be happy to have in your home.

EV Smart Tariff Advice

Research EV Tariffs –  It could save you hundreds of pounds a year!

If you are buying an electric vehicle or already have one, in my opinion, the most important thing you need to research is how you will charge your EV.

So many dealers sell electric vehicles without fully explaining how finding an off-peak tariff can drastically reduce the running cost of your electric vehicle.

@sarah_go_green When you buy a new EV the most important thing to get sorted is an off-peak rate for home charging! #octopusenergy #evtariff #evhokecharging #newev ♬ original sound – sarah_go_green

My neighbour recent bought an EV and commented how expensive he was finding home charging. After a conversation, I realised he was just charging his EV using his regular tariff.  If you have a driveway or a way to plug in at home switching to an electric vehicle tariff can save you hundreds of pounds a year.

Some basic maths on EV charging.

An electric vehicle has a battery that powers it.  Not all electric vehicle batteries are the same size. The battery capacity is measured in kWh. A Nissan leaf can hold 40 kWh, a Mini 32.6 kWh and a Tesla Model Y 75 kWh.

1 kWh can provide around 4 miles of driving.

If we take the Tesla Model Y. A typical rapid charger at the EV charging point on the motorway will current charge around 48p per kWh.

75 kWh x 0.48p = £33.75 to fully charge the Tesla Model Y at a motorway rapid charger.

If you have a home charger or even use the 3-pin plug charger that comes with your EV you can charge your electric vehicle off-peak for much less. Octopus Energy currently has 2 smart tariffs that offer an off-peak tariff for EV owners. They are Octopus Go and Intelligent Octopus. (There is also a variation on the Go tariff called Go Faster) These both offer an off-peak rate of 7.5p per kWh.

75 kWh x 0.75 = £5.63 to fully charge a Tesla Model Y at home. The only downside is that it is slower than a rapid charger so you may have to do it over more than one evening.  I tend to keep mine topped up to 80% and just add an extra few miles every night. It is, however, a massive saving over the course of a year.

Do you need a home charger?

A home charger is helpful as you can get 7 kW into your EV battery in an hour. The 3-pin plug gives you around 2 kW in an hour so it is much slower.  I have recently been using a 3-pin plug to charge at home and as I wasn’t doing many miles a day worked out fine BUT this was while my home charger was being fixed. I much prefer my home charger for the speed and the safety element.

Using an EV repaid charger is still cheaper than petrol.

If you don’t have the space to charge at home then don’t worry as charging an EV is still cheaper than filling up at the pump and is better for the planet. Plus you can always grab a free charge using a kWh EV charger that Tesco!!
