Two mid-table UK export tariffs, both tied or partly tied to import choices. The headline rates differ by roughly 6p/kWh — but the right pick depends on which import tariff you want alongside.
Octopus Outgoing pays 12p/kWh for solar export (cut from 15p in March 2026) but requires you to be an Octopus import customer too. EDF's variable export tariff pays 5.6p/kWh to EDF import customers; anyone else gets EDF's open-to-all rate of 3p/kWh. Octopus wins on every kWh exported. If you don't want to switch import supplier, Scottish Power SmartGen (6p, open to all) beats both EDF rates.
