Frequently asked questions about tariffs in South East England

South East England 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 South East England. 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 South East England was 31.95p/day from Eon Next. Standing charges are paid every day regardless of how much energy you use, so a low standing charge particularly benefits low-consumption households.

A heat pump needs only about a third of the energy a gas boiler uses for the same heat, but it is all electricity, so your electricity use goes up a lot and 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.

Tariffs with a daily supplier feed are updated every day; the others are checked by hand when the supplier publishes new prices. Each tariff card says which. The most recent rate change recorded for South East England is dated 7 Nov 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.
