So Energy tariffs and pricing
Typical tariff types
- Fixed-rate tariffs – Unit rates and standing charges are locked for a set term (e.g., 12 months). Good for budgeting. Early exit fees may apply if you leave before the end of your term.
- Standard variable tariffs (SVT) – Rates can move up or down and are influenced by market conditions and the Ofgem energy price cap. No fixed end date; usually no exit fees.
- Economy 7 / two-rate meters – If you have a multi-rate meter, So Energy may offer off-peak night rates and day rates. Suitability depends on your usage pattern.
What affects your price? Your region, meter type (single rate vs two-rate), payment method (e.g., Direct Debit), annual usage (kWh) and tariff choice all influence your final cost. The easiest way to see accurate prices is to compare with your actual usage.
Renewable electricity with So Energy
Many So Energy tariffs match your electricity consumption with renewable generation using REGOs (Renewable Energy Guarantees of Origin). This means for every unit of electricity you use on eligible tariffs, an equivalent amount of renewable electricity is added to the grid annually.
Renewable-backed electricity can help reduce your household’s market-based carbon footprint. Availability varies by tariff; always check plan details before switching.
Smart meters and usage insights
So Energy supports the national smart meter rollout. If your home is eligible, you can typically book a smart meter installation at no extra cost. Smart meters send automated readings and can provide near real-time consumption data via your In-Home Display, helping you understand and reduce energy use.
- Automated meter readings (no more manual submissions)
- Accurate billing based on actual usage
- Better visibility of peak vs off-peak consumption
Installation appointments are subject to engineer availability and your property’s technical suitability.
