How small business electricity is billed
A typical bill combines the unit rate charged per kWh consumed with a fixed daily standing charge that covers the cost of maintaining the connection regardless of usage. For small business electricity, the standing charge often represents a meaningful share of the total annual bill because consumption volumes are moderate.
Additional pass-through costs, including network charges and government-mandated environmental levies, are usually built into the headline unit rate rather than itemised separately on a standard fixed contract.
Indicative small business electricity consumption
| Premises type | Typical annual kWh | Notes |
|---|---|---|
| Small independent shop | 15,000 - 25,000 | Lighting and refrigeration dominant |
| Café or small restaurant | 20,000 - 40,000 | Kitchen equipment increases load |
| Small office (5-15 staff) | 20,000 - 45,000 | IT equipment and HVAC dominant |
| Small workshop or trade unit | 30,000 - 50,000 | Machinery use varies significantly |

Green and renewable-backed electricity
Many suppliers offer renewable-backed electricity tariffs at little or no premium to standard tariffs for small business customers, typically supported by Renewable Energy Guarantees of Origin certificates. These do not guarantee the physical electrons supplied to the meter come from a renewable source, but they do support the wider renewable generation market.
Businesses that want to demonstrate sustainability credentials to customers or in tender documents often find this a straightforward way to do so without significant additional cost.
Regional and network cost variation
Electricity network charges vary across the UK's regional distribution areas, meaning identical consumption profiles can produce different bills depending on location. This is separate from wholesale energy cost and reflects the cost of maintaining local infrastructure.
When comparing quotes across multiple sites in different regions, it is normal to see different unit rates even where the supplier and contract terms are identical.
Meter reading accuracy
Small business electricity meters are often read less frequently than domestic meters, which can lead to estimated billing between actual reads. Submitting regular meter readings, or upgrading to a smart meter, helps ensure bills reflect actual consumption rather than estimates.
Disputed estimated bills are one of the most common causes of billing complaints in the small business segment, so accurate reading data is worth prioritising.
