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, refreshed daily.

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 can use four to six times more electricity than a house heated with gas uses gas - so even small differences in unit rate or off-peak window have large bill impact. 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 is determined by your postcode. The first character of your MPAN (the 13-digit electricity supply number on your bill) is also the DNO letter code. Once signed in to Heat Pump Tariffs, we can pick this up automatically from your smart meter data so you don't have to look it up manually.

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.

Standing charges, unit rates and ToU band information are refreshed every 24 hours from supplier publications. Dynamic tariffs (Octopus Agile, Tracker, EDF FreePhase Dynamic) publish new rates daily and are read live during personalised comparisons using your smart meter data.
