Octopus Energy tariffs June 2026 — every deal, ranked

Every Octopus Energy tariff — June 2026 table

Annual costs use Ofgem's TDCV (2,700 kWh electricity + 11,500 kWh gas, dual fuel DD) where applicable. Verified June 2026 against Octopus's published tariff information labels and tracker dashboards.

Annual costs use Ofgem TDCV at standard cap-aligned regional rates. Tracker and Agile are averaged across mid-June 2026 daily/half-hourly prices — your bill will vary with wholesale and consumption pattern. Get an exact postcode-level quote via the comparison form.

Octopus 12M Fixed v18, Tracker or Agile? The July 2026 cap maths

Octopus's standard cap-tracking variable rises from £1,632/yr to £1,862/yr on 1 July 2026 — the same headline jump as every other supplier's default. So the meaningful choice is between Octopus's three flagship tariff types.

Octopus 12M Fixed v18 (£1,632/yr) locks in today's cap-aligned price for 12 months with no exit fees. Saves £218/yr versus the post-1-July cap. Best for households that want certainty and don't want to actively manage their energy usage. If wholesale gas falls sharply in autumn 2026 and Octopus launches a cheaper fix, the no-exit-fee structure lets you switch freely.

Tracker v3 (averaging £1,488/yr in June 2026) is priced daily on the previous day's wholesale market — your unit rate changes every morning. Mid-June 2026 averages suggest a £1,488/yr equivalent at TDCV, around £144/yr below Fixed v18. The risk: wholesale gas can spike (it did in Feb 2025 and Sept 2024), pushing the daily rate above the cap. Tracker has a daily price ceiling of ~100p/kWh as a safety net but no cap-equivalent annual ceiling.

Agile (averaging £1,520/yr June 2026) prices every half-hour on the day-ahead wholesale market. Bills are 10–25% lower than Fixed v18 for households that can avoid the 16:00–19:00 peak window (when prices regularly hit 50–80p/kWh). Worst for homes with cookers, dishwashers and tumble dryers running through the early evening peak. Best for homes with batteries, smart appliances, and the discipline to time-shift.

Bottom line: for a typical household with no battery and standard usage patterns, Octopus 12M Fixed v18 is the safest choice this month. For smart-home enthusiasts with a battery, Agile or Tracker can comfortably beat Fixed v18 — at the cost of monthly bill variability.

Octopus Go vs Intelligent Octopus Go — EV tariffs explained

Octopus Go is the simpler product: 8.5p/kWh between 00:30 and 05:30 (five-hour window), 30.1p peak. Works with any home charger including dumb timer-based units. Best for low-mileage EV drivers (under 8,000 miles/yr) who can comfortably charge inside the five-hour window.

Intelligent Octopus Go is the smarter product: 7p/kWh in a six-hour window 23:30–05:30, with automatic extension if your car needs more charge than the standard window allows. The 7p rate also applies to all household electricity used during the smart-controlled window, not just car charging. Requires a compatible smart charger (Ohme, Wallbox, Andersen, Indra, Hypervolt) or compatible vehicle (Tesla, Polestar, Hyundai, Kia, Ford, BMW i-series, etc.). Octopus's tariff page lists current compatibility.

Octopus's 7p off-peak rate is currently the lowest EV tariff in the UK — undercutting E.ON Next Drive (6.7p over a seven-hour fixed window), EDF GoElectric Overnight (9p over five hours) and British Gas Electric Driver v3 (8.95p over five hours). For high-mileage EV drivers (20,000+ miles/yr), Intelligent Go's automatic extension is the killer feature. Compare at your postcode in the form above.

Octopus Cosy — 13p heat pump tariff in three windows

Octopus Cosy charges 13p/kWh in three off-peak windows: 04:00–07:00, 13:00–16:00 and 22:00–00:00 — that's nine hours of cheap electricity spread across the day, matched to typical heat-pump duty cycles (pre-heat in early morning, top-up at lunch, evening cool-down). Outside those nine hours, electricity sits at the standard cap-aligned rate.

Cosy works best with a heat pump that has weather-compensation controls and (ideally) a buffer tank or hot-water cylinder. The 13:00–16:00 window is particularly useful in winter — it lets the pump pre-heat the home before the 16:00–19:00 peak, when wholesale prices are highest. For a 3-bed semi running an 8 kW heat pump with ~5,500 kWh annual electricity demand, Cosy typically beats both the standard variable cap and competitor flat-rate heat-pump tariffs (E.ON Next Heat Pump v2 at 14p; British Gas Heat Pump Tariff at 14.5p) — but only if the pump can actually shift demand into the three windows.

If your heat pump runs continuously through the day with no scheduling control, the simpler flat-rate competitors (E.ON Heat Pump v2 or British Gas) can be a better choice. Use the comparison form to model both at your postcode.

Octopus solar tariffs — Flux, Intelligent Flux, Outgoing Lite

Octopus Flux is the headline solar-plus-battery tariff. Export rates vary by half-hour between 5p/kWh (lowest demand) and 29.32p/kWh (peak demand — typically 16:00–19:00). Import rates are also half-hourly variable. Best for households with a 5+ kWh home battery that can store solar generation and discharge during peak windows. Typical Flux households see net bills 30–60% lower than standard variable for the import portion, plus meaningful export earnings.

Intelligent Octopus Flux adds AI-managed battery dispatch — Octopus's system automatically charges and discharges your battery to maximise export earnings, with peak export up to 32.17p/kWh. Requires a compatible battery system (Tesla Powerwall 2/3, GivEnergy AIO, Fox ESS and others). Best for hands-off solar households that want maximum return without manual battery scheduling.

Outgoing Octopus Lite is the open-market SEG product — 4.1p/kWh flat export for solar owners whose import is on a non-Octopus tariff. Lower than fixed-rate alternatives (E.ON Next Export 16.5p, British Gas Export & Earn Plus 15.1p) but doesn't require you to leave your current supplier for import. Use the comparison form to model SEG earnings against your solar output.

Octopus reputation — Citizens Advice, Trustpilot, customer service

Octopus Energy has been the consistent top-rated UK domestic supplier for the last six years on Citizens Advice's quarterly star rating — typically scoring 4.5 to 5 stars out of 5. Where Octopus dominates: response time on customer-service queries (often inside 24 hours), strong app and online account experience, and the breadth of tariff innovation. The customer-service team is UK-based across Brighton, London, Manchester and Warwick.

Trustpilot (June 2026): around 4.7 stars (Excellent) across ~250,000+ reviews — the highest of any large UK energy supplier. Some recent friction in 2025 around the Shell Energy migration (legacy customers reported billing-system reconciliation delays), but the dust has largely settled by mid-2026. For most households Octopus offers both the lowest tariffs (Intelligent Octopus Go, Cosy, Flux) and the best service — a rare combination in UK energy retail.
