There are two rates of Climate Change Levy:
• The main rates of CCL
• The Carbon Price Support (CPS) rates of CCL
Main rates of CCL
The main rates of CCL tax the supply of specified energy products ('taxable commodities') such as electricity, gas and coal for use as fuels (that is for lighting, heating and power) by business consumers, including consumers in:
The main rates of CCL do not apply to taxable commodities supplied for use by domestic consumers, or by charities for non-business use.
These rates of CCL are intended to change business behaviour in the UK to reduce energy consumption and/or consider using energy produced from renewable sources such as wind farms, solar energy and hydro power. For further details follow the link below:
CPS rates of CCL
The CPS rates of CCL tax the supply of specified energy products ('CPS rate commodities') such as coal and gas for use in electricity generation on or after 1 April 2013. Owners of electricity generating stations other than Combined Heat and Power (CHP) stations and operators of CHP stations, who generate electricity, must register with and account for the CPS rates of CCL to HM Revenue & Customs (HMRC).
These rates of CCL are intended to maintain a clear price for carbon emissions, encouraging the electricity generation industry to invest in low carbon emission technology. The CPS rates of CCL form part of the Carbon Price Floor (CPF).
You can find further information about CPF and CPS rates of CCL here:
There is also a CPS rate of fuel duty, which is payable on oils used to generate electricity. Businesses will account for CPS through their fuel duty returns. You can find out more information about this in the following HMRC Notice:
All rates of CCL are charged at a specific rate per unit of energy. For the main rates of CCL, there is a separate rate for electricity, natural gas, liquid petroleum gas (LPG) and solid fuels.
For the CPS rates of CCL, there are separate rates for natural gas, LPG and solid fuels.
You can find the current main rates and CPS rates of CCL by following the link below.
For the main rates of CCL, you should register if you supply fossil fuels or electricity generated from fossil fuels for commercial consumption.

Both the main rates and CPS rates of CCL are declared on form CCL 100; the Climate Change Levy return. When you have registered for CCL you must send this form to HMRC to declare the tax due for each accounting period. Accounting periods normally cover a three month period, although you can ask for non-standard accounting periods.
HMRC will send the CCL 100 to you, and it will show the date by which HMRC must receive the completed return and payment made (the due date).
The CCL 100 Climate change levy return must be signed by a responsible person:
• in the case of a limited company this should be the director or company secretary
• one of the partners in the case of partnerships
• the proprietor in the case of sole proprietorships
• an authorised official in the case of an unincorporated body
• a trustee or beneficiary in the case of a trust
A Welsh Language version of the form (CCL 100W) is available from the address shown in paragraph 7.2 of Notice CCL 1 'A general guide to Climate Change Levy'.
The term ‘reliefs’ covers exclusions, exemptions and the reduced rates that can apply to the main rates of CCL. You can find out more about these reliefs and whether you may be able to claim any in the following Notices:
For the CPS rates of CCL, there are no exemptions or reliefs, but there are some supplies which are outside the scope of the tax. You can find out more about this in:
