The Climate Change Levy (CCL) is a government tax on energy for business customers. The tax is levied on all business users of energy, including the public sector, at the point of final consumption. The tax aims to reduce energy use to help the UK meet its commitments to reduce greenhouse gas emissions under the Climate Change Convention.

Who needs to pay?

All UK businesses need to pay, with the following exceptions:


  • Energy intensive sectors (covered by the Integrated Pollution and Prevention Control Directive ) will receive discounts of up to 80%
  • Horticultural producers using energy for specific growing or sterilisation purposes will receive discounts of 50%
  • Domestic, residential and registered charity users are exempt
  • Good quality combined heat and power (CHP) and renewable generation is exempt (except for large-scale hydro generation)
  • There are also exemptions for some processes that use energy, but not as fuel


If you think you are eligible for a discount, let us know so that we can collect the right amount of tax from you.
