Frequently asked questions about tariffs in London

London is served by UK Power Networks, the Distribution Network Operator responsible for electricity distribution in this part of the UK. Your DNO is set by where you live; you cannot change DNO, but you can choose your electricity supplier freely from any company that serves this region.

Each of the 14 UK DNO regions has its own network distribution costs, set by Ofgem. These costs are passed through to suppliers, who reflect them in the unit rates and standing charges shown on your bill. Two identically-named tariffs from the same supplier can cost different amounts depending on which region you live in - so it always pays to compare using rates specific to your postcode.

Yes. Octopus Energy actively supplies customers in London. Heat-pump-friendly tariffs such as Cosy Octopus and Octopus Agile, and the EV-focused Intelligent Octopus Go, all have published rates for this region. Eligibility for individual products (such as Intelligent Octopus Go) may still depend on having a compatible smart meter and EV charger.

At the time of the latest update, the lowest published standing charge in London was 37.93p/day from EDF. Standing charges are paid every day regardless of how much energy you use, so a low standing charge particularly benefits low-consumption households.

Heat pumps consume significantly more electricity than gas boilers consume gas, so the unit rate you pay matters a great deal. On a flat-rate standard tariff, savings depend heavily on insulation and how efficiently the heat pump is run. Time-of-Use tariffs such as Cosy Octopus, or dynamic tariffs such as Octopus Agile, are usually cheaper for heat pump households because they let you draw most of your electricity during off-peak periods.

Tariff rates and standing charges shown on this page are refreshed daily. The most recent rate change recorded for London is dated 5 July 2026. Dynamic tariffs (such as Octopus Agile and Tracker) publish new rates every day; their headline numbers shown here are illustrative off-peak figures rather than fixed prices.
