What Is the Climate Change Levy?

The Climate Change Levy (CCL) is a UK government environmental tax on energy supplied to non-domestic (business and public sector) users. It was introduced in April 2001 to encourage businesses to improve energy efficiency and reduce carbon emissions. CCL applies to electricity, natural gas, LPG, and solid fuels such as coal used in non-domestic premises.

CCL does not apply to domestic households. It is charged by energy suppliers directly on business energy bills and shown as a separate line item. Businesses pay CCL in addition to their unit energy cost. Your energy supplier remits CCL to HMRC quarterly.

Domestic premises are fully exempt from CCL. Businesses in an approved Climate Change Agreement receive 92% off electricity CCL and 89% off gas CCL. Renewable electricity backed by REGO certificates is also exempt from CCL.

Climate Change Agreements (CCA)

A Climate Change Agreement is a voluntary deal between an energy-intensive business sector and the Environment Agency. Participating businesses agree to meet energy efficiency improvement targets in exchange for large CCL discounts. The CCA discount is 92% on electricity and 89% on natural gas.

CCA participation is available to qualifying energy-intensive manufacturing sectors: steel, chemicals, cement, ceramics, glass, food and drink, paper, textiles, and others. If you are in a qualifying sector, contact your trade association about joining the relevant CCA umbrella scheme.

Renewable Energy and CCL Exemption

Electricity generated from qualifying renewable sources and backed by a Renewable Energy Guarantee of Origin (REGO) certificate is exempt from CCL. Businesses can purchase 100% renewable electricity tariffs from suppliers who hold REGO certificates, effectively eliminating CCL on their electricity. This is a key financial motivation for green energy procurement beyond its environmental benefit.

Frequently Asked Questions

The Climate Change Levy (CCL) is a UK environmental tax charged on non-domestic (business and public sector) energy use. It applies to electricity, natural gas, LPG, and solid fuels such as coal. It was introduced in April 2001 to incentivise businesses to reduce energy consumption and carbon emissions.
The CCL rate for electricity in 2025/26 is £0.00775 per kWh. Businesses in a Climate Change Agreement (CCA) receive a 92% discount, paying only 8% of the main rate — effectively £0.00062 per kWh.
The CCL rate for natural gas in 2025/26 is £0.00672 per kWh. Businesses in a Climate Change Agreement receive an 89% discount, paying only 11% of the main rate — approximately £0.00074 per kWh.
Yes. Energy supplied to domestic premises (homes) is completely exempt from CCL regardless of the amount consumed. CCL applies only to energy consumed in business, industrial, commercial, and public sector premises.
A Climate Change Agreement is a voluntary agreement between an energy-intensive business sector and the Environment Agency. Under a CCA, businesses commit to improving energy efficiency targets. In return, they receive significant discounts on CCL — 92% off electricity CCL and 89% off gas CCL.
Electricity generated from qualifying renewable sources is exempt from CCL if it is backed by a Renewable Energy Guarantee of Origin (REGO) certificate. Businesses buying 100% renewable-backed tariffs may claim CCL exemption on that electricity.
Yes. Your energy supplier adds CCL to your business energy bill and shows it as a separate line item. If you are CCA-exempt or meet another exemption condition, you must provide a valid CCL exemption certificate to your supplier for them to remove or reduce the CCL charge.
Yes. CCL paid as part of business energy costs is a deductible expense against business profits for corporation tax or income tax purposes. The CCL forms part of the energy cost and reduces taxable profit in the normal way.
Yes. VAT is charged on the full energy bill including the CCL component. Business energy is usually charged at the standard 20% VAT rate, though some supplies qualify for the reduced 5% rate. The CCL is part of the taxable supply for VAT purposes.
CCL exemptions include: energy from renewable sources backed by REGO certificates; energy used for qualifying combined heat and power (CHP) schemes; domestic supplies; and energy used in certain transport and international shipping sectors.
Key strategies: join a Climate Change Agreement if in an eligible energy-intensive sector (92% electricity and 89% gas discount); switch to renewable electricity contracts backed by REGOs (exempt from CCL); invest in onsite solar generation; improve energy efficiency to reduce consumption overall.
Energy-intensive sectors most affected include: manufacturing (steel, chemicals, cement, ceramics, glass), data centres, commercial real estate, retail, hospitality, and food processing. These sectors also benefit most from Climate Change Agreement discounts.
