Octopus Energy Rates in the UK – Compare Tariffs & Switch Today

Fixed-rate Octopus tariffs

Fixed-rate tariffs give you price certainty. Your unit rate (p/kWh) and standing charge are fixed for the length of the contract (typically 12–24 months), although your overall bill will still change depending on how much energy you use.

• Ideal if you want protection from potential price rises
• Easier to budget with predictable rates
• Exit fees may apply if you leave before the end of the term

Flexible Octopus (variable tariff)

Flexible Octopus is the standard variable tariff. Prices can go up or down with wholesale costs and Ofgem price cap changes, but there are usually no exit fees, giving you flexibility.

• Freedom to switch again without penalties
• Rates can decrease as well as increase
• Linked to Ofgem's price cap for standard variable tariffs

Smart time-of-use tariffs (Agile, Go & more)

With a compatible smart meter, Octopus offers innovative time-of-use tariffs that reward shifting your usage to off-peak periods.

• Agile Octopus – half-hourly prices that reflect wholesale markets
• Octopus Go – cheaper night-time electricity, popular with EV charging
• Intelligent Octopus – smart EV charging with optimised off-peak rates

These tariffs can be extremely competitive if you are able to move high-usage activities (such as EV charging, washing, or heating) into cheaper time bands.

Green Octopus tariffs

Many Octopus tariffs are backed by 100% renewable electricity, sourced from wind, solar and hydro. Some deals also offer greener gas options via carbon offsetting or biogas.

• 100% renewable electricity on eligible tariffs
• Support the transition to a low-carbon energy system
• Often priced competitively with non-green tariffs

Unit rate (pence per kWh)

This is the price you pay for each unit of energy you use, measured in kilowatt-hours (kWh). Octopus Energy unit rates differ across gas and electricity and vary by region and tariff type.

Standing charge (daily fee)

A fixed daily charge that covers the cost of maintaining your connection to the energy network and running customer service operations. Standing charges can differ between tariffs and suppliers.

Billing frequency and payment method

You may be able to choose between monthly direct debit, on-receipt of bill, or prepayment (depending on your meter type). Many of the most competitive Octopus Energy rates are available when paying by monthly direct debit and opting for online billing.

Estimated vs actual readings

With a smart meter, your readings can be sent automatically, so you're billed for what you actually use. Without a smart meter, submitting regular manual meter readings helps avoid estimated bills and keeps your monthly payments more accurate.
