How Business Bills Differ from Domestic

Business electricity bills have several key differences from household energy bills.

%

20% VAT vs 5% Domestic

Businesses pay the standard 20% VAT rate on energy, compared to just 5% for domestic customers.

CCL

Climate Change Levy

The CCL is an environmental tax that applies only to non-domestic energy supply. The 2025-26 rate is 0.775p/kWh.

HH

Half-Hourly Metering

Larger businesses use half-hourly (HH) meters, meaning their charges vary by time of day with red, amber, and green time bands.

No

No Price Cap

The Ofgem Energy Price Cap only applies to domestic customers. Businesses negotiate rates directly with suppliers.

KVA

Capacity Charges

Businesses may pay capacity charges (in kVA) for their agreed supply capacity. Exceeding agreed capacity incurs excess charges.

PT

Pass-Through Contracts

Many business contracts use pass-through pricing, where third-party charges are billed at cost rather than bundled.
