Energy in London

London sits in the London distribution region (network area "C"), and that matters because the per-kWh unit rates and daily standing charges you pay are set partly by your local distribution network, so they differ from someone in Yorkshire or the South West. Octopus Energy supplies the whole London region — inner boroughs and outer ones alike — so wherever you are inside the M25 you can switch to them. We deliberately don't quote pence-per-kWh here: regional rates move with the Ofgem price cap, so always check the current London rates on octopus.energy before you commit. What stays the same is the £50 credit through a referral link, which is independent of your region and stacks on top of whatever tariff you land on.

• The £50 only reaches your account if you sign up through the referral link directly — typing octopus.energy or coming via a comparison site usually means London switchers get nothing.
• Your meter, cables and (in much of central London) shared supply infrastructure don't change; Octopus just takes over billing, so flats and conversions switch as easily as houses.
• London renters can switch too as long as you pay the energy bill — you don't need to own the property, just have an account in your name.
• The £50 lands automatically about 2-4 weeks after your switch completes and your first Direct Debit is taken, with no form to claim it.

How to switch in London

Wherever you are in the London distribution region, switching is the same simple process: tap the referral link, enter your address and a meter reading, and Octopus arranges everything with your current supplier. Your supply is never interrupted, and once your first Direct Debit clears your £50 credit is added automatically.
