Price is the main factor: but four other variables determine whether a deal is right for your London household.

London's South East zone runs 24.5p to 26.1p/kWh. A fixed deal below these rates saves on every appliance.
Standing Charge (p/day)
~57p/day electricity + ~29p/day gas (~£314/year combined). Low-standing-charge tariffs benefit low-usage flats.
