Electricity Cost in the UK 2026 Per kWh Rates & How to Save
UK electricity costs an average of 34p per kWh under the Ofgem price cap in Q2 2026, with a daily standing charge of 61p. The average UK household uses 2,700 kWh per year, resulting in an annual electricity bill of approximately £1,800 (including gas). Rates have stabilized somewhat after the 2022-2023 energy crisis but remain significantly higher than pre-crisis levels. Fixed tariffs below the cap are available and can save £100-300/year.
Ofgem Price Cap Explained
The Ofgem Energy Price Cap sets the maximum amount suppliers can charge per unit of energy and as a daily standing charge. As of Q2 2026, the cap is 34p/kWh for electricity and 6.76p/kWh for gas, with standing charges of 61p/day (electricity) and 32p/day (gas). The cap is reviewed quarterly and applies to default/variable tariffs. You can potentially pay less by switching to a competitive fixed tariff. The cap does NOT limit your total bill — it limits the per-unit rate. Higher usage means a higher bill.
How UK Electricity Rates Compare
The UK has some of the highest electricity prices in Europe, driven by wholesale energy costs, network charges, environmental levies, and supplier margins. UK (34p/kWh): Among the highest in Europe. France (27p/kWh): Lower due to nuclear power. Germany (39p/kWh): Even higher than UK. Spain (24p/kWh): Lower with strong renewable growth. USA ($0.168 = ~14p/kWh): Much cheaper due to abundant domestic energy. The UK's high rates make energy efficiency and solar panels particularly worthwhile investments.
Fixed vs Variable Tariffs
Variable (SVR): Tracks the Ofgem cap, currently 34p/kWh. Changes quarterly. No exit fees. Fixed tariff: Locks in a rate for 1-2 years. Currently available at 28-32p/kWh from competitive suppliers — below the cap. Exit fees may apply (typically £30/fuel). Recommendation: If you can find a fixed tariff below 34p/kWh, lock it in. Use comparison sites like Uswitch, Compare the Market, or MoneySupermarket. Always compare the total annual cost including standing charges, not just the unit rate.
Economy 7 and Time-of-Use Tariffs
Economy 7: Lower overnight rate (~15p/kWh) for 7 hours, higher daytime rate (~40p/kWh). Best for homes with storage heaters or EV charging. Only saves money if 40%+ of usage is overnight. Octopus Agile: Half-hourly rates that track wholesale prices. Can be very cheap (even negative) overnight but expensive during peaks. Best for tech-savvy users with smart appliances. Octopus Go / Intelligent Go: Flat 7.5p/kWh overnight rate specifically for EV owners. The best EV charging tariff in the UK by far.

|---|---|---|---|
| Ofgem Cap (Variable) | 34p/kWh | 61p/day | Default — switch away |
| Best Fixed Tariff | 28-32p/kWh | ~55p/day | Most households |
| Economy 7 (Night) | ~15p/kWh | 65p/day | Storage heaters, EV |
| Economy 7 (Day) | ~40p/kWh | (included above) | Avoid daytime heavy use |

| Octopus Agile (avg) | 20-40p/kWh | ~45p/day | Tech-savvy, flexible |
How to Reduce Your Electricity Bill
1. Switch tariff: Compare and switch to a fixed deal below the cap — saves £100-300/year. 2. LED lighting: Replace all bulbs with LED — saves £50-100/year. 3. Smart thermostat: Reduce heating usage by 10-15%. 4. Draught-proofing: Seal windows, doors, and letterboxes — saves £50-100/year. 5. Loft insulation: 270mm loft insulation saves £200-400/year on heating. 6. Solar panels: A 4kW system generates 3,400 kWh/year, saving £800-1,100/year at current rates.
