Enter the units (kWh) you have used, your unit rate and your daily standing charge, and this estimates the bill for the period. Defaults are the current electricity price cap; both parts together are what you actually pay.
Every energy bill has two parts: the unit rate you pay for each kWh you use, and a fixed standing charge for every day you are connected, whether you use anything or not. The standing charge is why a bill is never zero even in an empty home. To find your units used, take the difference between two meter readings. For more on each part, see understanding your energy bill and standing charges explained.
Common questions
How is my energy bill calculated?
You pay a unit rate for each kWh used, plus a daily standing charge for being connected. Add the two for the period and you have the bill. Under the current cap, electricity is 26.11p per kWh with a 57.19p daily standing charge.
What is the standing charge?
A fixed daily fee covering the network and your connection. It applies every day regardless of how much energy you use, so even an empty property is billed for it.
Does this include VAT?
The default price-cap rates already include VAT at the reduced 5% rate for domestic energy, so the total shown is what you would pay.
