Why aren’t the Octopus smart tariffs on comparison sites?
It is hard to compare these tariff against a traditional tariff without knowing your normal daily pattern of use. If you are able to shift loads from the peak times you will reduce the cost of your electricity overall.
How do I know I will save money?
Unfortunately, energy comparison sites can’t do the calculations for you as this innovative product is so different to the traditional tariffs and each household has a different consumption pattern. Octopus Energy are keen for these tariffs to work and have a transparent pricing formula, sometimes related to the spot price of electricity for each half hour period, they are also the Which recommended provider for the seventh year in a row, and are rated 5 stars on Trustpilot!
Without a smart meter you will need to estimate your use, you could use an energy monitor and find your normal electrical demand during the day. Or just give the tariff a try, if it isn't cheaper there are no exit fees! Remember to use our link to get £50.00 credit on your bill to make a saving from the start.
If you are already using a smart meter, see if you can download your half hourly consumption data from your current supplier, then merge the data with our historic Octopus tariff prices files (make sure the dates and time local or UTC line up) and multiply the amount consumed by the price to get the cost for each half hour. Find the sum of the all the half hour segments and compare this to your bills for the period (including the daily standing charge if applicable) to see if you would have paid less, even without any simple lifestyle changes.
Do I have to change my lifestyle?
No, but, with a little planning you could save more money. Start with the largest electrical loads and see if they can be planned to avoid the peak periods or even better planned for the cheapest rate times. Large consumption items include:
- Electric vehicle charging
- Immersion heaters
- Electric underfloor heating
- Tumble driers
- Washing machines
- Dish washers
- Electric hobs and ovens
Many of these large consumer items are becoming smart and have features such as delayed start or timed finish so you can control the timing. Older appliances could have there start time adjusted using a timer switch. Remember, when the prices go negative (plunge pricing) these are the appliances you should plan to use. Before running these appliances during the night, please do think of fire safety; check your smoke alarms, make sure doors are closed and have an escape plan!
The price is mostly lower than a traditional tariff, but could it cost me more?
Yes, using large loads during the peak time can cost more, this tariff puts you in control. The tariffs are capped to protect you from extreme spot prices.
I have / I am thinking of getting photovoltaic (PV) solar panels, does this make a difference?
That’s great, depending on the direction of your solar panels you could find that you are generating a lot of your own electricity during the peak time which saves you even more money. When planning use of large consumption appliances, you will have to consider the weather as well as the tariff prices to maximise your savings.
I have / I am thinking of getting battery storage, does this make a difference?
Yes, with enough battery capacity you could charge them at the lowest rate and during price plunges, then power your house from the batteries during the peak time.
