Agile Octopus

Half-Hourly Pricing

A dynamic electricity tariff where your price changes every 30 minutes based on wholesale market rates. When demand is low and renewables are plentiful, prices can drop below zero — meaning you get paid to use electricity.

Plunge Pricing: prices can go negative when supply exceeds demand
Price Cap Protect limits the maximum rate to £1/kWh
Average Agile customers saved £440 per year compared to standard tariffs
Electricity only — no gas version available
No exit fees — switch away any time

Best for

Tech-savvy households with solar panels, batteries, or the flexibility to shift energy use to cheaper periods.

Requirement

Requires a SMETS2 smart meter

📊

Octopus Tracker

Daily Wholesale Pricing

Your unit rate changes daily to reflect the wholesale market price of energy. Unlike Agile, Tracker uses a single daily rate rather than half-hourly slots, making it simpler to follow while still benefiting from market drops.

One daily rate for electricity and gas, updated after midnight
Based on independently published day-ahead auction prices
Price Cap Protect: max 100p/kWh (electricity) and 30p/kWh (gas)
No exit fees, but you cannot rejoin for 9 months after leaving
Long-term Tracker customers saved over £1,400 vs Flexible since 2021
12-month fixed term for the formula and standing charges

Best for

Customers comfortable with some price variability who want to benefit from falling wholesale costs.

Requirement

Requires a smart meter and existing Octopus account

What's changing in April 2026?

Smart Tariff Savings

Tracker and Agile tariffs continue to undercut the cap during calm market periods, offering the biggest savings.

Which tariff is right for you?

Not sure where to start? Here's a quick guide based on your situation.

→ Flexible Octopus

No commitment, no exit fees, and rates that follow the Ofgem cap. The easiest option for most households.

“I want to lock in my rates for the year”

→ Agile Octopus

Charge your battery when prices are lowest (or negative) and use stored energy during expensive peaks.

One daily rate that tracks wholesale costs. Simpler than Agile, and historically cheaper than the cap.
