The rates
| Direct debit | Now | Since last quarter | Against Great Britain |
|---|---|---|---|
| Electricity, per kWh | 26.55p | up 0.22p | 0.23p more than average |
| Electricity, per day | 55.41p | down 2.43p | 0.58p more than average |
| Gas, per kWh | 8.09p | up 0.67p | 0.12p more than average |
| Gas, per day | 29.96p | up 0.66p | 0.28p more than average |
Gas includes 5% VAT. Electricity carries no VAT until 31 March 2027, so the electricity changes against last quarter include VAT coming off.
Prepayment
Electricity 25.74p per kWh, gas 7.80p per kWh. Standing charges are the same as direct debit.
Economy 7 and other multi-rate meters
54.64p a day, and an average of 25.14p per kWh across day and night. How that splits into a day and a night rate is up to each supplier, so check your bill for yours.
