Questions
- Do I have to be an Octopus import customer for Outgoing?
- For the headline rate, yes. Octopus offers a lower export-only SEG rate to homes supplied by someone else; the SEG guide lists both.
- Is Outgoing the best export rate?
- It is the best-known flat rate with no installer condition. The SEG guide on this site lists higher rates that require the supplier's import tariff or their installer.
