What to Look for in a London Energy Deal
Price is the main factor — but four other variables determine whether a deal is right for your London household.
Unit Rate (p/kWh)
London's South East zone runs 24.5p–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.
Contract Length & Exit Fees
12 or 24 months. Exit fees £50–£100/fuel if leaving early. Waived in final 49 days — switch freely.
Payment Method
Direct debit is cheapest. Standard credit costs £60–£120 more per year. Prepayment carries a further premium.
Green Energy Certification
London has strong demand for green tariffs. Certified 100% renewable options are clearly labelled on Switch.
