Octopus Saving Sessions pay a fixed rate per kWh saved during peak hours
Octopus Energy pays registered customers for reducing electricity use during designated “saving sessions” called by the National Grid Electricity System Operator (ESO). The payment rate for winter 2025/2026 was confirmed at £3.00 per kWh saved, paid as bill credit (Octopus Energy Saving Sessions terms and conditions page, October 2025).
Octopus Saving Sessions pay £3.00 per kWh saved, with typical earnings of £10-£60 per winter season. A gas-heated 3-bed semi averages £28, while heat pump homes earn around £52.

Savings are calculated against a baseline of the household’s average electricity use during the same time window on the previous 10 weekdays. Only the kWh you reduce below your baseline earns payment. You are not paid for your normal consumption.
Typical household earnings range from £10 to £60 per winter season
A typical three-bedroom semi-detached home with gas heating earned an average of £28 across the 2025/2026 winter session period (Octopus Energy blog, “Saving Sessions results winter 2025/26”, April 2026). Households with electric heating or heat pumps can earn more because they can shift larger loads, averaging £52 for these homes.
Maximum earnings for any single session in 2025/2026 was £18.60 for homes with a heat pump and battery storage (Octopus Energy customer data published on their community forum, March 2026). Earnings are paid as a one-off bill credit within 14 days of each session, not as cash.
Quick numbers what a typical session pays
| Household type | Typical baseline (kWh per session) | Typical reduction (kWh) | Typical payment per session (£) | Typical total across 12 sessions (£) |
|---|---|---|---|---|
| Gas-heated flat, no storage | 1.2 | 0.4 | 1.20 | 14.40 |
| Gas-heated 3-bed semi | 2.5 | 0.9 | 2.70 | 32.40 |
| Electric-heated 3-bed semi | 4.0 | 1.8 | 5.40 | 64.80 |
| Heat pump + battery 4-bed detached | 6.5 | 3.5 | 10.50 | 126.00 |
Baseline and reduction figures are averages from Octopus Energy’s published session results for December 2025 to February 2026 (Octopus Energy “Saving Sessions results” page, accessed March 2026). Total assumes 12 sessions per winter, the number actually called by the ESO in 2025/2026.
The National Grid ESO calls sessions when the grid is under strain, typically 4–7pm on winter weekdays
Saving sessions are triggered by the ESO’s Demand Flexibility Service (DFS), which pays suppliers to reduce demand during peak risk periods (National Grid ESO, “Demand Flexibility Service 2025/26”, published October 2025). Sessions are announced by text or app notification 24 hours in advance. You cannot choose which days to participate.
Typical session window is 1–2 hours between 4pm and 7pm, though occasional late-evening sessions occur. You are not penalised for missing a session. You simply earn nothing for that day.
To earn anything, you must shift your electricity use outside the session window, not just turn things off
Payment is calculated only on the kWh you reduce below your baseline. If you use more than baseline, you earn nothing for that session. You are not charged extra either.
Effective strategies include delaying dishwasher, washing machine, tumble dryer, and oven use until after 7pm. Heat pump users can preheat the house before the session starts, then let the temperature drift down during the window. Battery storage owners can charge from the grid before the session and discharge during it. This is the highest-earning strategy.
The payback calculation depends entirely on whether you can shift load without inconvenience
If you already run appliances in the evening, shifting them to after 7pm costs nothing in money or time. It is pure profit. If you would need to buy a smart plug, timer, or battery to participate, the earnings are unlikely to cover the equipment cost within one winter.
A £50 smart plug and timer setup would take 2–3 winters to pay back at typical earnings. This is not recommended as a purchase solely for Saving Sessions. The only exception is a home battery (5–10 kWh), which can earn £80–£150 per winter and has a separate payback case from solar self-consumption. home battery payback 2026
You must be an Octopus Energy customer with a smart meter to register for Saving Sessions
Eligibility requires an Octopus Energy domestic electricity account with a working smart meter in SMETS2 or SMETS1 (if enrolled on the DCC network) (Octopus Energy, “Saving Sessions eligibility” page, accessed 2026). You register through the Octopus Energy app or website. No installer or certification is needed.
Octopus Energy is the only supplier currently offering DFS-based saving sessions to all domestic customers. Other suppliers run similar schemes but under different names and rates. There is no MCS, TrustMark, or Gas Safe requirement because Saving Sessions involve no installation. Only meter data is used.
