Is Octopus Energy Green?

Yes, on all standard Octopus tariffs, electricity is 100% matched with renewable generation via REGO certificates. Octopus Agile, Go, and Flux tariffs additionally help balance the grid by shifting demand to periods of high renewable generation, reducing carbon intensity further than REGO matching alone.

For gas: Octopus does not currently offer 100% green gas (biomethane) as standard. A small additional charge unlocks a green gas match if this matters to your household.

Octopus Energy and Smart Meters

Octopus is one of the UK's most active smart meter installers. SMETS2 required for Agile, Go, Intelligent Go, and Flux tariffs.

SMETS2 (post-2018)

Full compatibility, all smart tariffs available. Half-hourly reads submitted automatically.

SMETS1 (pre-2018)

May lose smart function initially. Octopus upgrades SMETS1 to SMETS2 free of charge.

No smart meter

Traditional meter accepted for standard tariffs. Request free SMETS2 installation on sign-up for smart tariffs.

Economy 7 smart meter

Check Agile or Go tariff compatibility. Confirm night-rate billing before switching.

Can You Switch to Octopus on a Prepayment Meter?

Yes, Octopus accepts prepayment meter customers. Four things to know before you switch.

£500 debt limit applies

If you owe more than £500 to your current supplier per fuel, you cannot switch until the debt falls below this threshold. Ofgem rules apply across all suppliers.

New key or card within 5 days

Octopus sends your replacement prepayment key or card within 5 working days of your switch completing. Your supply continues uninterrupted throughout.

Free upgrade to credit meter

Customers with no debt history can request a free conversion from prepayment to a standard credit meter, usually completed within a few weeks.
