Quick answer: Standing charges are fixed daily fees on energy bills covering grid and supplier costs — you pay them even when usage is zero, and they rose sharply during the energy crisis.
Ofgem caps both unit rates and standing charges for default tariffs. Low energy users pay a higher proportion of their bill in standing charges than heavy users. This guide explains the structure and how to compare tariffs fairly.

Price cap structure
Ofgem sets maximum standing charge and unit rate levels for the default tariff cap each quarter. Both components are capped separately, so a low unit rate may come with a higher standing charge.
Standing charges vary by region because network costs differ across distribution areas. The same cap methodology produces different daily charges depending on your postcode.
Comparing deals
Use a total annual cost estimate for your actual usage profile when comparing tariffs. Comparison sites show standing charge and unit rate separately so you can see the full picture.
Economy 7 electric-only households may have a standing charge on both rate bands depending on the tariff. Factor both daily charges into your comparison.
Future reform
Policy debate continues on moving some policy costs from the standing charge to the unit rate. Watch Ofgem consultations for changes that could help low users who pay a high fixed daily fee.
Smart meters enable time-of-use tariffs where a daily standing charge still applies regardless of when you consume energy. The standing charge remains even on agile tariffs.
Common questions
Can I avoid standing charges?
Some tariffs minimise the standing charge but raise unit rates instead. Compare total annual cost for your usage level rather than focusing on one component alone.
Do standing charges apply when away?
Yes — the daily standing charge accrues whenever your account is active, even in months when your consumption is zero. Closing your account or switching supplier stops the charge from that date.
Are standing charges the same for prepayment?
Prepayment meters pay the same capped standing charge as credit meters under current Ofgem rules for price-capped tariffs. The daily fee is deducted from your meter balance alongside unit costs.
