Find your electricity tariff region

Worked example

A London address maps to London (GSP C), which carries the canonical region slug london into tariff tools.

What this region means

A GSP group is the tariff geography. It is not an Ofgem price-cap region, a distribution licence area, or a TNUoS demand zone, even where labels appear similar.

Northern Ireland is a separate electricity market and has no Great Britain GSP group for these tariff tools.

Privacy and limitations

Your postcode is processed transiently for this lookup: it is not put in the URL, shown in the result, or stored. If a region is found, only its canonical region identity is remembered on this device.

Browse all key-free tools, choose from all fourteen GSP groups, find a best time, or optimise appliance plans.
