Next update: when Ofgem reprints the next quarterly cap or Octopus changes Agile’s published rules.
By: Switch Editorial Team, Switch Squid Ltd
Octopus Agile is a half-hourly smart electricity tariff that does not sit under the Ofgem default-tariff price cap — so you should judge it against the October–December 2026 dual-fuel Direct Debit typical bill of £1,723, not against a made-up “Agile saves £X” average. Ofgem confirmed that £1,723 figure on 26 August 2026 (about 4% above the restated July £1,663). Agile publishes 48 unit rates for the next day, rewards load-shifting, and carries Octopus’s own Price Cap Protect ceiling of 100p/kWh. It can beat a boring SVT if you move demand. It can also cost more if you cook and charge at 5pm every night.
I am Switch. This page explains Octopus Agile tariff UK 2026 in plain English, with the official cap maths you need for a fair comparison, then sends you to live compare CTAs. I will not invent an Octopus “typical Agile annual bill” I have not calculated from your half-hourly data.

What Octopus Agile actually is
Agile is an electricity import tariff from Octopus Energy. Instead of one unit rate all day, you pay a different pence-per-kWh price for each of the 48 half-hour slots. Octopus publishes tomorrow’s schedule in the afternoon (commonly around 4pm, exact time can vary). Your smart meter must send half-hourly reads so Octopus can bill the right slot. Standing charges still apply every day and vary by distribution region — Agile does not delete the standing charge.
Rates track the day-ahead wholesale market plus network costs and Octopus’s tariff uplift. Evening peaks (often late afternoon into early evening) are usually dearer. Quiet overnight and high-renewable slots can be cheap — sometimes plunge-priced. Regional differences matter: London is not North Scotland.
Ofgem October 2026 cap — the benchmark
| Item | Oct–Dec 2026 Direct Debit | Source |
|---|---|---|
| Typical dual-fuel annual | £1,723 | Ofgem news 26 Aug 2026 |
| vs Jul–Sep restated | £1,663 (+4%) | same |
| Electricity unit (GB avg) | 26.32p/kWh | Ofgem unit rates |
| Electricity standing | 54.83p/day | same; 0% VAT on elec this period |
| Gas unit (GB avg) | 7.97p/kWh | same; 5% VAT on gas |
| Gas standing | 29.68p/day | same |
The cap limits default (SVT) unit rates and standing charges for households on standard variable tariffs. Agile is not an SVT default product priced from that cap. Comparing Agile to £1,723 is still the right household conversation, because that is the bill many people will pay if they do nothing before 1 October 2026. Fixed deals and other time-of-use tariffs are separate products — judge each on its own quote.
Price Cap Protect at 100p/kWh
Octopus documents an upper limit on Agile import unit rates — commonly described as Price Cap Protect at 100p/kWh including VAT — so a wholesale spike cannot bill you an uncapped half-hour. That ceiling is a crisis backstop, not a comfortable everyday rate. It is also not the Ofgem SVT cap. Do not confuse the two in a FAQ answer to your neighbour.

Who Agile suits in 2026
- EV drivers who can schedule charging overnight or into cheap plunge slots.
- Heat-pump or high-electric homes with automation (smart schedules, batteries, immersion timers).
- Households happy to watch the app and shift dishwasher / tumble / oven away from peak windows.
- Not people who need a single predictable Direct Debit and cannot move load — take a fixed dual-fuel quote or an SVT and sleep.
Agile is electricity-focused in the classic product story. Gas for heating may still sit on a separate Octopus tariff. When you compare “versus £1,723”, remember £1,723 is dual-fuel typical use — your electricity-only Agile maths will not equal that headline unless you rebuild both fuels.
How to compare Agile to the £1,723 cap without lying to yourself
- Export a few weeks of half-hourly usage from your smart meter / Octopus account (or a previous supplier’s HH data if you have it).
- Multiply each half-hour’s kWh by a sample Agile day from your region (Octopus publishes the schedule).
- Add your regional standing charge × days.
- Compare that illustration to an SVT illustration built from the October electricity pence at the same kWh, then add your gas if you are dual-fuel.
- If you cannot do the arithmetic, do not switch on vibes — use a fixed quote compare instead.
Blog posts that shout “families save £440 a year on Agile” without your usage profile are marketing. SwitchSquid will not reprint an unsourced saving as fact.
Agile vs Octopus Go / Cosy / fixed — quick map
| Product type | Price behaviour | Best for |
|---|---|---|
| Octopus Agile | 48 half-hour rates daily | Flexible / automated load |
| Octopus Go (EV) | Cheap night window, higher day | Predictable overnight EV charge |
| Fixed dual-fuel | Locked unit rates for term | Budget certainty |
| SVT under Ofgem cap | Moves with quarterly cap | Do-nothing default |
Go is often simpler for EV drivers who only need a known cheap overnight block. Agile is for people who will chase plunge pricing and accept peak risk. Fixed is for anyone who hates the app. The October £1,723 SVT illustration is the do-nothing baseline.

Smart meter prerequisites
Without working half-hourly smart meter data, Agile cannot bill correctly. If your meter is dumb, in tick mode, or stuck on monthly estimates, fix that before you romanticise wholesale prices. Octopus’s own Agile pages and help centre cover eligibility — follow those, not a third-party checklist from 2024.
Risks people underweight
- Evening peak lifestyle — family dinner + EV plug-in at 5:30pm on Agile is how bills inflate.
- Standing charges — still there every day even when unit rates plunge.
- Regional spreads — never judge Agile from a national screenshot.
- Gas — dual-fuel £1,723 includes gas; Agile electricity wins do not automatically cut the gas half.
- Exit / product rules — read Octopus terms for how you leave Agile if it is not working.
Export, solar and batteries — keep the products straight
If you have rooftop solar, Agile import pricing is only half the story. Export may sit on a separate Outgoing / SEG-style product with its own rates. A home battery that charges from the grid on plunge slots and discharges through peak dinner can amplify Agile’s upside — and it can also create messy bill narratives if you do not log what the battery did. SwitchSquid’s rule on this URL: explain the import tariff cleanly first. Do not blend solar export pence into an Agile “saving” unless you have both schedules in front of you.
Heat-pump households should be even more careful. Cosy Octopus and other heat-pump tariffs exist precisely because a single half-hourly import product is not always the gentlest fit for steady winter heat demand. If your heat pump runs hard through the evening peak, model that season before you leave a fixed electricity deal for Agile.
Direct Debit budgeting on a spiky tariff
Agile’s unit rates move daily; your Direct Debit usually does not. Octopus will still collect a smoothed DD and reconcile. That smoothing can hide a bad month until the balance catches up. Check the account balance monthly for the first quarter on Agile. If the balance climbs while your lifestyle has not changed, you are probably charging expensive half-hours — fix the schedule before winter.
For dual-fuel homes, keep gas DD and electricity DD mentally separate when you read the October £1,723 headline. Agile will not rewrite your gas standing charge. A brilliant Agile electricity month plus an unchanged gas SVT can still produce a bill that feels like the cap.
What to do this week (before 1 October 2026)
If you are on an SVT, the October cap rise is coming. Options, ranked by how much homework you want:
- Compare fixed dual-fuel quotes on MoneySuperMarket via our Awin link and on the SwitchSquid energy hub.
- If you already have half-hourly data and automation, model Agile for two weeks before switching.
- If you drive an EV and want simplicity, evaluate Octopus Go alongside Agile — same family, different shape.
- If you cannot shift load, ignore Agile Twitter and take the fixed or SVT path with eyes open.

FAQ
Does the Ofgem price cap apply to Octopus Agile?
No. The cap limits default SVT rates. Agile is a separate half-hourly product. Octopus applies its own unit-rate ceiling (Price Cap Protect, 100p/kWh) instead.
What is the October 2026 dual-fuel price cap figure I should remember?
£1,723 a year for a typical Direct Debit dual-fuel household on the 2026 typical-use benchmark, as published by Ofgem on 26 August 2026.
Can Agile be more expensive than the cap?
Yes. If your usage sits in expensive half-hours, your electricity unit costs can exceed a capped SVT illustration. That is the trade for access to cheap slots.
Do I need a smart meter for Agile?
Yes — working half-hourly data is part of how the tariff bills. Fix meter issues before you switch.
Is Agile good for EV charging?
It can be, if you schedule charging into cheap slots. If you only want a fixed cheap overnight window, compare Octopus Go as well.
Will SwitchSquid quote my Agile annual bill?
Not from a national average. Without your half-hourly profile, any £/year saving claim is fiction. Use the MSM compare and Octopus’s own tools with your data.
Where do I compare normal fixed and SVT deals?
Use MoneySuperMarket (campaign 911601) and switchsquid.com/energy/.
