Octopus Agile customers fall into two groups. The first group switches, forgets about it, and saves around £150-200 passively from the structural difference between Agile rates and the standard price cap. That is not nothing. But it is not why people switch to Agile.
The second group builds a habit. They check prices each evening. They shift their washing machine and dishwasher to overnight windows. They stop using high-draw appliances between 4pm and 8pm. They save £400-600 per year. The difference in effort between these two groups is about 60 seconds per day. Everything starts in the first week.
Here is a day-by-day plan for week one on Octopus Agile.
Day 1: getting your region set on AgileAlert
Your first action is to set your DNO region on AgileAlert. This takes two minutes and makes every price you see accurate for your specific part of the UK.
Agile prices vary by DNO (Distribution Network Operator) region. There are 14 regions across Great Britain, from Scottish Hydro in the north to South Western in the southwest. The price for any given 30-minute slot can differ by 1-3p/kWh between regions. Over a year, that matters.
Open AgileAlert. Find the region selector. Identify your region from your postcode. Our full guide on what a DNO region is and why it affects your Agile prices walks through this in detail if you are unsure.
Once your region is set, look at the price chart for tonight. Identify the cheapest overnight window, usually somewhere between 11pm and 6am. Note the approximate time that prices drop below 8p/kWh. That is your window. Tonight, you are going to use it.
Also note the price chart for tomorrow evening. Specifically, look at the 4pm to 8pm zone. In most regions, on most days, this is the most expensive period of the day. Prices regularly reach 25-50p/kWh during these four hours. Everything discretionary that you can avoid running in this window will save you real money.
Day 2: your first overnight run
Tonight, you run something in the cheap window you identified yesterday. Pick one appliance: your washing machine or dishwasher. Set it to run at the start of the cheapest period.
Most modern washing machines have a delay timer. Set it to start at midnight, 1am, or whichever time sits in the lowest-price window for your region tonight. If your dishwasher has a delay start function, the same principle applies.
A standard washing machine cycle at peak time (say, 35p/kWh) costs roughly 16-20p. The same cycle at 4p/kWh costs about 2-3p. That is a saving of around 14-17p per wash. Across 150 washes per year (three per week), that is roughly £21 per year from a single appliance. Add the dishwasher, the tumble dryer, and the EV charger if you have one, and the numbers grow fast.
The first overnight run feels almost inconsequential. That is fine. The point is not the saving from one wash. The point is that you do it, it works, nothing goes wrong, and the habit takes root. Tomorrow morning you will wake up to a completed load of laundry and a sense that Agile is already working for you. That feeling is the foundation of the habit.
Day 3: understanding your first half-hourly usage chart
Open the Octopus app. Navigate to your usage section. You should see a bar chart or graph showing your electricity consumption broken into half-hour slots. This is data you have never had access to before switching to Agile. It is one of the most revealing things you will see about your home's energy behaviour.
Look for the shape of your consumption. Most households show clear patterns. There is typically a morning rise as people wake up, a quieter period during the day, a significant evening peak starting around 5-6pm, and then a drop into nighttime. The evening peak is where the money is being spent.
Now look specifically at the 5pm to 8pm window. What is running in your house during that time? The dishwasher after dinner? The oven? A tumble dryer? Each of these can be moved. Not eliminated: moved. The same tasks, at a fraction of the cost, simply by starting them later.
Look also for any unexpected spikes. An appliance that runs autonomously on a schedule you set years ago and forgot about. A boiler that fires during peak hours when a timer adjustment could shift it. A storage heater charging at the wrong time. These are the hidden costs that half-hourly data exposes and Agile rewards you for fixing.
Day 4: the peak avoidance habit
Today you establish the single most valuable rule on Agile: nothing discretionary runs between 4pm and 8pm.
The 4-8pm window is when Agile prices spike hardest. This is the national grid's peak demand period. Working households come home, turn on appliances, start cooking, and run baths. Grid demand surges. Agile prices reflect that surge in real time, sometimes reaching 40-50p/kWh or more during cold winter evenings.
By contrast, overnight prices on Agile are routinely 2-8p/kWh. The price difference between peak and overnight is frequently a factor of five to ten. Every kilowatt-hour you move from peak to overnight is a saving of 20-40p. This is not optimisation at the margins. It is structural repricing of your household energy consumption.
The rule is easy to state: the washing machine runs at midnight, not 7pm. The dishwasher runs after 10pm, not after dinner. The tumble dryer runs overnight, not before school in the morning. These are not sacrifices. The clothes are still clean. The dishes are still done. The saving is simply in when those tasks happen.
Households that apply this rule consistently save £100-150 per year from peak avoidance alone, before accounting for any other Agile optimisation. It is the single highest-return behaviour change on Agile.
Days 5-7: building the evening check into your routine
The sustained saving on Agile comes from a single 60-second habit: checking tomorrow's prices each evening.
Octopus publishes the next day's Agile prices every afternoon, usually between 4pm and 5pm. AgileAlert displays them immediately. Open AgileAlert each evening before bed. Look at tomorrow's overnight window. Note when the cheapest period starts. Set your appliance timers accordingly. Close the browser.
That is it. Sixty seconds. The appliances do the rest while you sleep.
Over the first week, this habit requires conscious effort. You have to remember to check. By week three, it becomes automatic. By week six, you do it without thinking about it, the same way you check the weather before choosing what to wear.
The households that save £600 per year on Agile are not doing anything complicated. They are doing this one check, every evening, without fail. The accumulated saving of 365 daily checks is what separates the £200 customer from the £600 customer.
If prices are genuinely low overnight (below 5p/kWh), consider running everything you can: washing machine, dishwasher, charge the laptop, top up the EV. Occasionally prices go negative on Agile, meaning Octopus literally pays you to use electricity. Those are bonus nights. But even ordinary nights at 3-6p/kWh represent massive savings compared to the 26.11p/kWh price cap rate.
What to look at on your first bill
Your first Agile bill arrives after your first full billing period, typically one month. Here is what to look for and how to interpret it correctly.
Compare to the same period last year, not last month. Energy consumption is highly seasonal. Comparing January (high heating, short days) to December is meaningless. Compare your first Agile month to the same month from your pre-Agile billing. If you cannot access that data, compare your average unit rate to the price cap rate of 26.11p/kWh.
Check your average unit rate. The Octopus app or bill will show your average blended rate for the billing period. This is the effective price you paid per kWh after averaging all 30-minute slots weighted by your consumption. Under 15p average is an excellent result for an engaged first month. Under 20p is good. Above 22p suggests you are still consuming heavily during peak hours and there is room for improvement.
Look at your half-hourly usage data against the price chart. Octopus provides both your consumption and the prices for each slot. Lay them against each other. Are your peaks happening during expensive slots? This is the clearest picture of where your remaining savings lie. Use it to refine your timing for month two.
Do not panic about the standing charge. Agile has a daily standing charge, typically around 40-50p/day depending on region. This covers your connection to the network and does not change with consumption. It appears the same on every bill. Some customers are surprised by it. It is normal and applies to every UK electricity tariff.
Your first bill is not a verdict. It is a baseline. Month two will be better than month one. Month six will be better than month three. The habit compounds.
