Applying for accreditation and claiming Levy Exemption Certificates (LECs)

Renewables and CHP Register

All parties wishing to participate in the exemption schemes must first register for a Generator account on the Renewables and CHP (Combined Heat and Power) Register. This is a web-based system used to administer many of the renewable and CHP schemes that we are responsible for.

Once your account has been activated, you can access it and apply for accreditation (for the Climate Change Levy exemption for Renewables), sign the relevant declarations, submit monthly output data and receive/transfer Levy Exemption Certificates (LECs) to other account holders.

More information about this process can be found on the Renewables and CHP Register section of this website.

Applying for accreditation

Applications for accreditation for the Climate Change Levy exemption for Renewables are made through our Renewables and CHP Register. Where you are applying for the CCL exemption for Renewables alongside the Renewable Energy Guarantees of Origin (REGO) and/or Renewables Obligation (RO) or Feed-in Tariffs (FIT) schemes one combined application for accreditation is made. Fuelled stations must also provide information to support the renewable qualifying percentage of fuels used to generate electricity.

Please note that due to recent changes to the CCL scheme, LECs cannot be issued on electricity generated after 31 July. If your generating station commissioned on or after 1 August 2015 and you have applied for CCL accreditation, no LECs can be issued. For more information, please see our CCL FAQs. We will be reviewing Register functionality relating to CCL accreditation and LECs in due course.

Accreditation for the Climate Change Levy exemption for good-quality CHP is obtained through CHPQA (Quality Assurance for CHP). In order to start claiming CHP LECs you will need to inform CHPQA of your intention to claim. They will forward the full details of your accreditation to us. We cannot receive these directly from operators of generating stations.

So that we can link your CHPQA accreditation record to your Renewables and CHP Register account, please email to inform us of your account and CHPQA station details.

Claiming Levy Exemption Certificates

To claim Renewable or CHP LECs, monthly generation data must be submitted within the Renewables and CHP Register within two months following the month of generation. Please refer to the Certificate Issue Schedule published at the bottom of this page. One Renewable or CHP LEC is issued per megawatt hour of eligible electricity.

LECs are issued within the Renewables and CHP Register before the end of the third month following the month of generation. July 2015 was the last month of generation eligible for renewable LECs. Please see our CCL FAQs for more details about the removal of the Climate Change Levy exemption for renewables. March 2013 was the last month of generation eligible for CHP LECs for indirect supplies. LECs are issued directly to the operator of the generating station or their agent where requested to do so.

For stations subject to a Non-Fossil Fuel Obligation (NFFO) or Scottish Renewables Obligation (SRO) contract, we issue LECs directly to the electricity suppliers entitled to receive them. LECs can then be transferred to a supplier’s account on the Renewables and CHP Register.
