UK electricity tariffs by region

Britain's electricity supply is split into 14 DNO (Distribution Network Operator) regions, each with distinct standing charges and unit rates. Choose your region below for a heat-pump-and-EV-focused breakdown of the best available tariffs, rebuilt every day.

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 against your specific area. For a fully personalised view, sign in and upload your half-hourly smart meter data; we'll match every tariff in your region to your real consumption pattern.

Why regional comparison matters for heat pump and EV households

Heat pumps

A heat pump needs only about a third of the energy a gas boiler uses to give the same heat, but all of it is electricity, so a heat pump home uses far more electricity than before. That means even small differences in unit rate or off-peak window have a large effect on the bill. Time-of-Use tariffs (Cosy Octopus, British Gas Heat Pump tariffs) and dynamic tariffs (Agile, Tracker) are typically much cheaper for heat pump households than flat-rate standard tariffs. Availability and rates of these products vary by region.

EVs

Overnight EV charging benefits from deep off-peak windows - Intelligent Octopus Go, E.ON Next Drive and similar tariffs publish dedicated low rates between roughly 23:30 and 05:30. Off-peak unit rates and the exact window times differ by region, and some products are only available where the DNO and meter combination is compatible.

Frequently asked questions

A DNO (Distribution Network Operator) region is one of 14 geographic areas covering Great Britain, each managed by a specific company responsible for the physical electricity distribution network in that area. Network costs differ between regions and feed into the standing charges and unit rates suppliers charge.

Your DNO region depends on where you live. The quickest way to find it is your electricity bill: the 2 digits after the S at the start of the bottom row of your MPAN (the 21-digit supply number) are your region code, from 10 to 23. You can also call 105 free from any phone to reach your local network operator. When you sign up to Heat Pump Tariffs you choose your region once, in Meter & region settings, and you can change it there at any time.

Suppliers are required to charge cost-reflective unit rates and standing charges in each region, because network costs (set by Ofgem) differ. A tariff branded under the same name from the same supplier - for example Octopus Cosy - therefore has 14 different price sheets, one for each DNO region.

There isn't a single "cheapest region" - the answer depends on how much electricity you use and when you use it. Standing charges are typically lowest in densely populated regions like London and highest in rural Highlands and Islands areas, while peak unit rates can vary in the opposite direction. The fairest comparison is always against the tariffs available in your own region.

Rates from Octopus Energy, EDF and E.ON Next come from their own published price lists and are updated every day. Other suppliers' rates are checked by hand when they publish changes. Dynamic tariffs (Octopus Agile, Tracker, EDF FreePhase Dynamic) publish new prices every day, and personalised comparisons use those prices with your own smart meter readings.
