The climate change levy and energy efficiency

To ease the impacts of climate change, the UK government provides several environmental tax and relief schemes encouraging business to take more environmentally friendly approaches across their operations. 

Introduced in April 2001, the Climate Change Levy (CCL) is one of these measures. We’ll walk through what it entails below.

The Climate Change Levy: An overview

The Climate Change Levy (CCL) is an environmental tax charged on the energy that businesses use. A means of encouraging businesses to be more energy efficient in how they operate, the CCL aims to reduce the overall emissions that businesses produce. 

In simple terms, the more energy efficient your business is, and the less carbon-emitting energy you use, the less CCL you’ll pay.

So who does it apply to? Any business in the industrial, public services, commercial and agricultural sectors is subject to the tax, which is charged on ‘taxable communities’ for heating, lighting and power purposes. It is not charged on road fuel and other oils that are already subject to excise duty. 

Your business must register for the Climate Change Levy. If you do not pay the Climate Change Levy – or you do not register – you'll have to pay a penalty of £250 for each instance.

How the Climate Change Levy rates work

CCL is paid at either the main rate or Carbon Price Support (CPS) rate, these differ in the following ways:

Main rates

Any business in the industrial, public services, commercial and agricultural sectors will be charged CCL at the main rate on electricity, gas and solid fuel use. You can find these main rates listed on your business gas or electricity bill.

Carbon Price Support rates

If you own generating stations or you operate combined heat and power stations, then you’ll be required to pay the Carbon Price Support rate. This levy rate varies for each commodity: kilowatt-hours for gas and electricity, and kilograms for all other taxable commodities.

That said, if you generate your own energy and make money through the Feed-in Tariff, it’s unlikely you will have to pay the levy since you’ll be classed as a small generator.

Paying a reduced rate on the CCL

If your business is looking to pay a reduced main rate on CCL charges, you’ll have to enter into a Climate Change Agreement (CCA) with the Environmental Agency. This is a voluntary agreement that aims to reduce your energy use and CO2 emissions.

However, there is a trade-off. Paying a reduced rate means you’ll be required to improve your business’ energy efficiency and lower your average energy consumption. You’ll also have to measure and report your business’ energy use and carbon dioxide emissions against targets set over for two-year terms.

Businesses bound by a CCA will receive a reduction of 90% in the CCL rate paid on electricity bills, and a 65% reduction on all other fuels. To check if your business is eligible for a CCA, head here.

Should you meet the targets set at the end of each term, you’ll then continue to receive the Climate Change Levy discount.

Climate Change Levy Exemptions

Your business may be exempt from paying the Climate Change Levy if you meet the following requirements:

  • Your business uses small amounts of energy – less than 33kWh electricity and/or 145kWh gas a day
  • You’re a domestic energy user, i.e., energy is used in homes, schools, caravans and self-catering accommodation
  • You’re a charity involved with non-commercial activities

You can find guidance on what constitutes charitable or domestic use in our VAT & CCL Guidance document here.

To claim for an exemption on paying the Climate Change Levy, you'll need to complete the Government's Climate Change Levy supplier certificate (PP11) and return it to our Customer Services team on

Even if you're not exempt, you may still be able to pay a reduced rate by making energy-efficient changes to your business. The best way to do this is to sign a Climate Change Agreement that we mentioned above.

Claiming back on the Climate Change Levy

If you've overpaid on your Climate Change Levy, then it's possible to claim a tax credit. Head to the page here for more information as well as the necessary forms you'll need to fill in.
