Climate Change Levy (CCL)

What is the Climate Change Levy (CCL)?

The Climate Change Levy (CCL) is a UK government tax introduced in 2001 to encourage businesses and the public sector to improve energy efficiency and reduce carbon emissions. Unlike RO, CfDs and FiTs, which fund renewable generation, CCL is a direct tax on energy consumption.

CCL applies to the supply of electricity, gas and certain solid fuels used for non-domestic purposes. It is charged per unit of energy consumed, regardless of when or how that energy is used.

The levy is administered by HMRC and is designed to create a price signal that incentivises lower energy use and investment in efficiency measures.


Who pays the CCL?

CCL is payable by non-domestic energy users, including businesses, charities and public sector organisations. Domestic consumers are exempt.


Energy suppliers are responsible for collecting the levy and passing it on to HMRC, but the full cost is passed through to customers via energy bills, usually as a clearly identifiable line item.

Some organisations may qualify for CCL relief or exemption, most notably:


  • Businesses with a valid Climate Change Agreement (CCA)
  • Certain energy-intensive processes
  • Supplies generated from qualifying renewable sources


How much is the CCL (and when are rates revised)?

CCL rates are set by the government and are typically revised annually, usually taking effect from 1 April each year. Rates are published by HMRC in advance to allow suppliers to update billing.


For both gas and electricity, CCL is charged on a pence per kilowatt hour (p/kWh) basis. The current CCL rates are 0.775p/kWh, set to rise to 0.801p/kWh from April 1st 2026, and then to 0.827p/kWh from April 1st 2027.


Unlike RO or CfDs:

  • CCL is not forecast or reconciled
  • There is no recycling or levy adjustment
  • The charge is fixed and unavoidable unless a formal exemption applies


Why CCL matters for businesses

Because CCL is a straight consumption tax, it directly rewards reduced energy use. Efficiency improvements, on-site generation, and CCA participation can all reduce CCL costs. This makes CCL one of the few policy costs that businesses can actively manage rather than simply absorb.

With consumer spending declining and OFGEM raising their price cap, you would be forgiven for seeing February as a month where negative news was at the forefront, but in the energy markets, this was not the case.

In a year that began with falling energy prices, there were recurring catalysts that led to prices climbing steadily higher. Geopolitical uncertainty and the perennial threat of escalating conflicts meant fear would maintain a constant presence in the wholesale markets. We will look back at the key energy stories from 2024, and how the energy markets are likely to shape up in 2025. Quarter 1  The year began with cautious optimism as the UK’s gas reserve levels were healthy and prices for the Summer’24 season were in freefall. In February, prices pulled back to their lowest levels since 2021, and for the first time in a while, we identified that there was greater potential for upside risk than for further downward price movement: “ there now (exists) an asymmetrical element of risk should the market encounter a supply-side problem of significance. ” During February we had advised customers on flexible contracts that this was an ideal time for making purchases. March would see prices begin to ascend again as international conflict would create problems with LNG imports, and we would highlight the geopolitical risks as an area for concern moving forwards: “ fears remain and there are potential negative catalysts that could lead to prices rising further, with the main factors to watch out for being based on geopolitical unrest. “ For a business that purchases their energy in advance, this quarter was the optimal time for purchasing during 2024. In February, electricity prices for Winter’25 were down to 7.75p/Kwh, and as low as 6.05p/Kwh for Summer’25. Winter’25 ended the year with prices above 11.1p/Kwh, with Summer’25 prices exceeding 9p/Kwh. For a company that uses 500,000Kwh of electricity per month, the difference between buying at the February low point compared to today’s prices would represent a yearly saving of over £200,000.
