What is a standing charge on a UK electricity bill?

On most domestic and business electricity bills in Great Britain, you will see two big moving parts: usage charged at a unit rate (pence per kWh) and a standing charge collected as a daily fee. They answer different questions — how much energy you used versus how much it costs to maintain your supply — but both hit the same invoice total.

What the standing charge actually is

The standing charge is usually quoted as pence per day (sometimes shown as pounds per month). It covers fixed costs associated with supplying your property — metering, network-related fixed components on your tariff, and sometimes supplier operational costs bundled into the tariff structure.

It is not “VAT” and it is not the same as your unit rate. Think of it as a baseline fee that accrues even if you use almost no electricity during the billing window (subject to your tariff wording).

How it appears next to unit rates

A typical summary section might look conceptually like this (line labels vary by supplier PDF layout):

Multi-rate tariffs (day/night, half-hourly export/import on advanced meters) add rows, but the pattern repeats:daily charge × billed days sits alongside kWh × rate.

Why suppliers separate fixed and variable costs

Suppliers structure tariffs so fixed network/admin components can be recovered steadily across customers, while usage reflects consumption. That is why two tariffs with similar headline unit rates can produce different totals if one has a much higher standing charge.

When comparing quotes (especially for businesses), treat unit rate and standing charge together— not in isolation.

What to check on your bill

• Billing period length: standing charge lines usually multiply the daily rate by the number of days in the period — confirm it matches the stated dates.
• Duplicate supply points: if you recently switched or had meter exchanges, watch for overlapping periods or stray accounts.
• Tariff version: end-of-fixed-term moves can change standing charge and unit rates together — compare against your renewal letter as well as the PDF.
• VAT band: domestic electricity is typically 5% VAT for ongoing supply in many cases, while business sites are often 20% — your bill should match your situation.

If usage looks flat but the total jumped, see our guide on unexpected bill increases — standing charge shifts are a common culprit alongside pass-through levies.
