What this instrument does

The Climate Change Levy (General) Regulations 2001 (SI 2001/838) provide the operational mechanics of the Climate Change Levy (CCL), a per-unit tax on energy supplies to non-domestic consumers. The CCL was introduced by the Finance Act 2000 to incentivise energy efficiency in the business sector.

Made by the Commissioners of Customs and Excise (now HMRC) under the Finance Act 2000, Schedule 6. In force from 1 April 2001. This is a tax instrument administered by HMRC, not a regulatory instrument administered by Ofgem.

How the CCL works

Energy suppliers (registrable persons) account for and pay the levy to HMRC. The economic burden passes to business consumers through energy prices. Domestic consumers are exempt under the enabling Act.

The Regulations do not set the CCL rates (those are in the Finance Act, updated annually). They provide the machinery for five categories of supply:

• Full-rate supplies: standard CCL applies
• Half-rate and reduced-rate supplies: for facilities covered by climate change agreements (voluntary energy efficiency targets negotiated with the Environment Agency)
• Exempt supplies: renewable-source electricity (via Levy Exemption Certificates), and other specified categories
• Excluded supplies: below de minimis thresholds, certain fuel types

Administration (Part II)

Registrable persons must submit returns for each accounting period and pay by the due date (Regs 4-6). They must maintain a "climate change levy account" and preserve records for six years (Regs 7-9).

Bad debt tax credits are available where a customer defaults after the supplier has accounted for CCL (Reg 10). Overpaid CCL may be reclaimed, subject to an unjust enrichment defence: HMRC may withhold repayment where the claimant has already passed the cost to customers (Reg 19).

Reduced rates for climate change agreements (Regs 44-45)

Facilities covered by climate change agreements (CCAs) receive reduced CCL rates. Businesses negotiate energy efficiency targets with the Environment Agency; in exchange, they pay a lower levy. This is the main policy lever connecting the CCL to industrial energy efficiency outcomes. Supplier certificates are required to support the reduced-rate treatment (Reg 34).

Renewable electricity exemption (Part IV)

Renewable-source electricity is exempt from the CCL. This operates through a certification system for generation, separate from the Renewables Obligation. The exemption provides an additional revenue stream for renewable generators through Levy Exemption Certificates (LECs).
