Grid Supply Point Region for a UK Postcode (Octopus Energy)

octopusenergy/grid-supply-point

The UK electricity grid supply point group a postcode belongs to, as a group id such as _C (London): the region key used to pick the right regional tariff code and rates. A postcode the service does not know returns an empty list. Pass the postcode with or without the space.
