How do I pick the best energy tariff in 2026?

Start from how and when you use energy. If you want certainty under the current price cap, look at a fixed deal below £1,723/yr; if you use a lot overnight, Economy 7/10 or an EV/time-of-use tariff can beat single-rate. Then compare your postcode with EnergyPlus.

What is the current energy price cap?

the Ofgem price cap is £1,723 a year for a typical dual-fuel direct-debit home (October–December 2026, confirmed by Ofgem). It caps default-tariff unit rates and standing charges, not your total bill, because your usage still drives the cost.

Is it worth fixing my energy tariff now?

Often yes. With several fixed tariffs already below the £1,723 price cap, locking in can save a typical home around £300 over 12 months. Check the term length and any exit fees against how long you expect to stay before committing.

Should I get Economy 7 or a normal tariff?

Economy 7 gives a 7-hour cheap night window with off-peak rates from about 12.5p/kWh. It wins when roughly 40% or more of your electricity is used overnight, such as with storage heaters, hot-water tanks or EV charging. Otherwise its higher day rate can cost more.

What is the best EV charging tariff right now?

Overnight EV rates start at 6.99p/kWh in 2026, including EDF GoElectric (6.99p, 23:00–06:00), Intelligent Octopus Go (8p, 23:30–05:30) and E.ON Next Drive (8.5p, 00:00–06:00). The best choice depends on your charger, car and usage pattern.

I have solar panels — how do I get paid for export?

Through a Smart Export Guarantee (SEG) tariff. The best 2026 flat rates are tied to taking that supplier's import tariff - around 12-13p/kWh (Ecotricity, E.ON Next) and 18p/kWh at EDF - with installer-locked deals up to 25p/kWh (Good Energy, needs a battery); Intelligent Octopus Flux is closed to new customers. Variable export floors sit around 5–7p/kWh.

What is the difference between the unit rate and the standing charge?

The unit rate is what you pay per kWh of energy you use. The standing charge is a fixed daily cost for staying connected, around 63p a day on average for electricity in 2026. Comparing both gives a truer picture, especially for low-usage households.

Will my energy supply go off if I switch?

Typically no. Switching changes the company that bills you, not the physical gas and electricity supply. Admin issues can occasionally delay completion, but supply interruptions are not expected.
