How Energy Cost Calculator 2026/27 Works
How electricity costs are calculated
Your electricity cost = (appliance watts divided by 1,000) multiplied by hours used per day multiplied by unit rate in pence. The standing charge is a fixed daily fee regardless of usage, currently around 60p/day (£219/year). Always added on top of your usage.
Ofgem price cap
The Ofgem price cap sets the maximum unit rate and standing charge suppliers can charge per unit of energy. It is reviewed quarterly. For Q2 2026 (April to June), the electricity unit rate cap is approximately 24.7p/kWh. This is what most households on a standard variable tariff pay.
How to reduce your electricity bill
Electric showers, ovens, and washing machines are the biggest consumers. Switching to an Economy 7 tariff if you have storage heaters, reducing shower time, and using appliances off-peak can cut bills significantly. An A+++ fridge-freezer uses ~75% less energy than an older model.
Frequently Asked Questions
The Ofgem electricity price cap for Q2 2026 (April to June) is approximately 24.7p/kWh with a 60p/day standing charge for a typical home on a standard variable tariff. This is reviewed every quarter by Ofgem. The cap peaked at ~52p/kWh in Q4 2022 during the energy crisis.
Ofgem estimates the typical UK home uses 3,500 kWh of electricity per year. Homes with electric heating, hot water, or electric vehicles use significantly more. An EV adds roughly 2,000 to 3,000 kWh/year depending on mileage.
Electric showers (8 to 10kW), tumble dryers (~2.5kW), electric ovens (~2kW), and washing machines (~2kW) use the most electricity. Running an electric shower for 8 minutes uses about 1.2 kWh, costing around 29p at current rates.
Fixed-rate tariffs are sometimes available below the price cap. Check comparison sites like Uswitch, MoneySuperMarket, or the Ofgem comparison tool. Always compare based on your actual usage rather than the headline rate.
