Frequently Asked Questions: Energy Switching
Will my power or gas ever turn off while switching?
No. Your electricity and gas flow through the same national grid pipes, wires, and meters regardless of which company bills you. The switch is purely an administrative update between energy suppliers.
Why does the Octopus page say "So Martin Steven made you an offer you couldn't refuse"?
That's my dad Martin! Octopus Energy automatically displays the referrer's name at the top of their sign-up page. When you switch through his link, Octopus splits £100 evenly: £50 goes onto your energy bill, and £50 onto his.
Do either Fuse Energy or Octopus charge exit fees?
No. Both Fuse Energy and Octopus Energy standard tariffs have £0 exit fees, meaning you can switch to another supplier at any time without paying a penny in exit penalties.
