How CCL charges have changed

The Climate Change Levy (CCL) -- a tax on business energy use to encourage environmental responsibility -- is seeing an increase in rates for gas and solid fuels starting April 1, 2024. This is designed to help with the government's goal of achieving net zero emissions by 2050.


What is the CCL?

The CCL is an environmental tax added to the electricity and gas bills of businesses and public sector organizations. It incentivises reduced greenhouse gas emissions and improved energy efficiency.


There are two main CCL rates:


  • Main Rate: Applies to all businesses in relevant sectors and varies depending on energy usage.
  • Carbon Price Support Rate: Applies to electricity generators and combined heat and power station operators (not changing in 2024).


What's Changing?

  • Main Rate Increase: The CCL rate for gas is rising from 0.672 pence per kilowatt-hour (p/kWh) to 0.775 p/kWh, matching the existing rate for electricity. This increase aims to create a level playing field between these energy sources and encourage businesses to be more efficient with both.
  • Solid Fuel Rate Increase: The rate for other solid fuels is also rising proportionally to gas.
  • Discount Rate Adjustments: Businesses participating in Climate Change Agreements (CCAs) receive discounts on the CCL in exchange for meeting energy efficiency targets. These discounts are being adjusted to reflect the main rate increase, ensuring CCA participants don't pay more tax.
  • LPG Rate Frozen: The CCL rate for Liquefied Petroleum Gas (LPG) remains unchanged.


Impact on Businesses

This CCL change will lead to higher energy bills for businesses that rely on gas and solid fuels. To mitigate the financial impact, businesses can explore options such as:


  • Energy Efficiency Audits: Identify areas of energy overuse and implement efficiency measures like LED lighting or improved insulation.
  • Renewable Energy Solutions: Consider switching to renewable energy sources like solar panels to reduce reliance on taxed fuels.
  • Ensuring they have the most competitive rates: By comparing all rates available or using a broker to negotiate on their behalf, businesses can make sure they are not over-paying on their unit rates.


The CCL is intended to be a nudge towards environmental responsibility, encouraging businesses to adopt cleaner energy practices. By taking steps to improve energy efficiency, businesses can not only reduce their environmental footprint but also potentially offset the financial impact of the CCL increase.

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.
