Tariffs
Tariffs — see what a different rate means for your whole home
Start with the rates you already pay, quick-fill an Ofgem benchmark, or enter a tariff you’re considering. Then see what it could change across electricity, gas, solar, battery, EV and heating.
Three ways to start
Use My Energy
Your current household rates and annual usage can already flow in from My Energy.
Quick-fill a benchmark
Use the current Ofgem default-tariff benchmark as a starting point, then edit anything that differs.
Enter any tariff
Have a supplier quote or tariff sheet? Enter the exact unit rates, standing charges and any one-off fees.
Supplier-by-supplier live market selection is not connected yet, so every populated figure remains visible and editable.

Common questions about comparing tariffs
- How do I compare two tariffs fairly?
- Use the same annual electricity and gas kWh for both tariffs, so only the rates and standing charges differ. This page does that automatically using your My Energy figures, then applies each tariff's rates to the same usage.
- What does the standing charge actually pay for?
- It's a fixed daily fee for being connected to the network, charged regardless of how much energy you use. It's added to your usage cost, so a low unit rate with a high standing charge can still cost more overall for low users.
- Is a time-of-use tariff worth it?
- That depends on how much of your electricity you can genuinely shift into the cheap period, which this page estimates from your assumed cheap-rate share. If little of your use happens overnight, a lower blended rate may not outweigh a higher daytime rate.
- How do exit fees and joining credit affect the first year?
- An exit fee on your current tariff and any joining credit on the new one are one-off amounts, so they're only added to the first-year total, not the ongoing annual figure. Look at both numbers, since a tariff can look better in year one but worse afterwards, or the other way round.
- Why doesn't this page search the market for me?
- No. It compares the rates shown. The Ofgem quick-fill is a reference benchmark, not a market search. A live supplier catalogue can be connected later without changing the calculation engine.
