How Do Business Electricity Bills Work? A Simple Guide for UK Companies

Whether you run a small startup or manage a multi-site operation, understanding your business electricity bill is key to managing overheads and spotting savings opportunities. But with all the line items, units, and charges, it can feel like decoding a foreign language.

In this guide, Scalex Technology explains how business electricity bills work in the UK—so you can read, understand, and manage your costs with confidence.

What’s the Difference Between Business and Domestic Electricity Bills?

While both include charges for electricity used, business energy bills are structured differently from domestic ones:

What’s Included on a Business Electricity Bill?

Here’s a breakdown of the typical components of a UK business electricity bill:

1. Standing Charge

A daily fee (£/day) for being connected to the grid—covers network maintenance and admin costs.

2. Unit Rate (kWh)

The cost per kilowatt-hour (kWh) of electricity your business actually uses. This can vary based on:

  • Time-of-use (ToU) tariffs
  • Contract type (fixed or flexible)
  • Market conditions

3. VAT

Usually charged at 20%. If you’re a charity or use less than 33 kWh of electricity per day, you may qualify for the reduced 5% rate.

4. Climate Change Levy (CCL)

A government tax to encourage lower carbon usage. Charged per kWh unless your business is exempt (e.g. certain charities or renewable users).

5. Metering Charges

Costs associated with data collection, meter operator (MOP) services, or maintenance—especially for half-hourly meters.

6. Capacity and DUoS/TNUoS Charges (for large businesses)

  • DUoS (Distribution Use of System): Local network delivery fees
  • TNUoS (Transmission Use of System): National grid delivery costs
  • Capacity charges: Penalties for exceeding your contracted demand

Sample Business Electricity Bill Breakdown

Imagine a bill for a small office with the following charges:

ChargeAmount
Standing Charge (30 days)£21.00
Unit Charge (1,200 kWh @ 25p)£300.00
CCL (1,200 kWh @ 0.775p)£9.30
VAT @ 20%£66.06
Total£396.36

How Is Business Usage Tracked?

Your bill is calculated based on your electricity meter readings, which may be:

  • Manual (you submit them)
  • Smart (auto-sent to supplier)
  • Half-hourly (HH) for high-consumption businesses

If readings aren’t available, suppliers may issue estimated bills, which can be inaccurate.
