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.

Understanding the Climate Change Levy in Detail
The Climate Change Levy (CCL) is an environmental tax on energy delivered to non-domestic users in the United Kingdom. Introduced in 2001 by the Finance Act 2000, its purpose is to encourage businesses, the public sector and agricultural operations to increase energy efficiency and reduce their carbon emissions. The levy applies to electricity, natural gas, liquefied petroleum gas (LPG) and solid fuels such as coal and coke, and is collected by the energy supplier on behalf of HMRC. It appears as a separate line on business utility bills and is payable in addition to VAT at the standard rate of 20%.
There are two main rates: the main rates that apply to most commercial and industrial users, and the Carbon Price Support (CPS) rates that apply specifically to fuels used to generate electricity. For 2025/26 the main rate on electricity is 0.775p per kilowatt-hour, on natural gas it is 0.775p per kWh, on LPG it is 2.175p per kg and on coal it is 6.064p per kg. These rates have risen steadily in line with the government's Net Zero 2050 commitment and are reviewed each Budget. Domestic customers and charities using energy for non-business purposes are exempt from CCL entirely, as are small businesses falling below the de minimis threshold of 33 kWh per day of electricity or 145 kWh per day of gas.
Reducing Your CCL Bill: Climate Change Agreements
Energy-intensive industries can claim a significant discount from CCL by entering into a Climate Change Agreement (CCA) with the Environment Agency. In exchange for meeting agreed energy-efficiency or carbon-reduction targets, operators receive a reduction of up to 92% on the electricity rate and 89% on the gas rate. Over 50 industrial sectors participate in the scheme, including chemicals, food and drink, paper, ceramics, glass and steel. Businesses that fail to hit their targets lose the discount and must pay the full rate retrospectively, so accurate metering and reporting are essential. The CCA scheme has been extended to 2027 and a replacement scheme is currently being consulted on.
How Businesses Can Minimise Their Levy
Beyond CCAs, there are several practical ways to reduce CCL exposure. Using electricity generated from renewable sources through a certified green tariff once qualified businesses for a 100% exemption, though this exemption was removed in 2015 and now only applies to electricity supplied via private wires directly from a renewable generator. Investing in energy-efficient equipment, LED lighting, building insulation, heat recovery and variable-speed drives all reduce consumption and therefore the levy payable. Combined Heat and Power (CHP) plants meeting "Good Quality" status under the CHPQA scheme qualify for levy exemption on the electricity output, providing a significant incentive for on-site generation. Our calculator above lets you model the impact of consumption changes, CCA discounts and fuel mix adjustments so you can quickly estimate the savings available to your business.
