Executive summary
This report focuses on one question: which suppliers give households the best value in 2026? We rank suppliers purely on total annual cost and tariff fairness for typical usage, as a cost-first companion to our full performance report.
Value leaders combine competitive unit rates with fair standing charges and no punitive exit fees.
Key findings
- The cheapest headline unit rate is not always the best total-cost deal once standing charges are included.
- Mid-size suppliers frequently offer the strongest value fixes.
- Exit fees can erode the value of an otherwise cheap tariff.
How we rank value
We calculate the total annual cost for typical dual-fuel usage in each region, combining unit rates and standing charges, then adjust for tariff fairness factors such as exit fees.
This gives a like-for-like comparison rather than a misleading headline-rate ranking.
