How the Standing Charge Calculator Works
The calculator converts a daily standing charge into monthly and annual costs by multiplying the daily pence figure by 365 days and converting to pounds. It then compares your current standing charge against a comparison figure you enter — from another supplier, tariff or an average — to show the difference over a year.
What Is a Standing Charge?
A standing charge is a fixed daily amount you pay simply for being connected to the gas or electricity network. It applies every day even if you use no energy at all, which is why it forms part of your bill regardless of how much you switch off.
Why Standing Charges Matter
Standing charges can make a meaningful difference to annual bills, particularly for low-usage households. If you use relatively little energy, the fixed daily charge can make up a large share of your total bill, so comparing standing charges between tariffs is worthwhile.
Electricity Standing Charges vs Gas Standing Charges
Electricity and gas usually carry different standing charges. Dual fuel customers typically pay both — a separate daily charge for electricity and another for gas — so the combined daily figure can be higher than people expect. This calculator lets you compare them separately or together.
Why Supplier Standing Charges Differ
Standing charges vary because of network and maintenance costs, your region, the tariff type, each supplier's own pricing decisions, policy costs and the market rules that govern how these charges are set. Two homes in different regions can pay quite different daily charges as a result.
