The New CCA Scheme (2026): Timelines, requirements and important updates

Find out the latest information ahead of CCA Phase 3

Phase three of the government’s Climate Change Agreements (CCAs) scheme is due to commence on 1st January 2026. This new five-year scheme will require businesses to actively participate, update their reporting practices and adapt to stricter targets for energy efficiency. 


Here we summarise the latest information to help you keep abreast of the changes and ensure eligibility. These updates include 2025 milestones and the full timeline for Phase 3 newly released in June 2025.


What are Climate Change Agreements?


Climate Change Agreements are voluntary compliance arrangements whereby eligible industries work towards energy reduction targets, and in return benefit from a reduction in the Climate Change Levy (CCL) – a tax on energy use designed to encourage energy efficiency and promote low-carbon technologies. 


The ongoing CCA scheme is important for organisations aiming to improve their sustainability credentials while managing energy costs. It provides a structured framework for businesses to achieve their environmental targets, engage in forward planning, and align with other carbon and energy legislation. 


Below we outline the latest updates and milestones to be aware of.


What you need to know about CCA Phase 3


Whilst 2025 is essentially a free or “fallow” year of CCL discounts without targets in place, Phase 3 is fast approaching with updates which may have some implications:


Eligibility

Businesses will need to demonstrate that they still meet the eligibility criteria and opt-in to the new scheme (at the time of writing the window for entry is still to be confirmed). Updates to the criteria as outlined here could impact ability to qualify.


Targets

Businesses will face stricter energy efficiency and carbon reduction targets aligned to the UK’s net zero goal. There will also be a new baseline of 2022 instead of 2018.


Savings Assessment Tool (SAT)


The scheme includes a Savings Assessment Tool (SAT) which facilitates annual reporting and is designed to help organisations estimate and document their energy and carbon savings. The next phase will require updates to the required information including:


  • 2022 baseline data.


  • Under the new scheme, targets will be set up differently, using the NOVEM method of energy allocation, which allows for more accurate reporting of a facility’s energy performance when production volumes or energy intensity vary between products.


  • Targets will be split between fixed and variable energy use and require operators to declare their proportions of each (and, where applicable, also between product categories).


  • Combined Heat and Power (CHP) reporting methodology changes which will include disclosing the proportional split between fuel for heat and fuel to generate electricity.


  • Facility-level reporting – all reporting will need to be conducted at facility level, with the ability to group sites under a single target no longer permitted.


  • Businesses will also need to report on potential energy savings, including from adopting renewables and savings from switching to CHP. Otherwise, from all planned efficiency projects.


Performance Account Template (PAT)


A mandatory requirement, the PAT is a standardised document, required at the end of each Target Period, to report on progress of a company's energy actions.


There will be a new requirement to report annual mid-target energy and production data in addition to target period end data.

The requirement will be to submit an updated Performance Account Template alongside the Target Period end data in the first quarter of the following year, specifically in the following timeframes:


Feb/Mar 2027 – submit for Phase 3 Target Period 1

Feb/Mar 2029 – submit for Phase 3 Target Period 2

Feb/Mar 2031 – submit for Phase 3 Target Period 3


CCA Phase 3 Timeline


CCA Phase 3, when incorporating both Target Periods and Certification Periods, will run from January 2026 until March 2033. The below table outlines the full timeline.

Climate Change Agreements (CCA) Phase 3 Timeline Table

CCA Glossary: key definitions


Facility: a single site which will now have to have its own CCA.


Certification Period:  a period of time during which compliance CCA holders are eligible for discounted rates of CCL.


Performance Account Template (PAT): a standardised document required by CCA to report the progress of actions impacting energy and carbon emissions.


Savings Assessment Tool (SAT):  a tool for documenting and estimating energy and carbon savings for the CCA scheme.


Target Period: a period of time used to calculate CCA holders’ energy efficiency to determine if they have met targets.


Target unit: facility or group of facilities that share a single CCA under the old scheme


Umbrella Agreements:  These agreements are between a sector association and the Environment Agency and contain a sector- specific commitment to energy efficiency improvements and carbon reduction targets for a specific period.


Underlying Agreements:  These agreements are held by operators for specific sites within a sector and contain targets appropriate for a specific type of operation.





We would encourage all scheme members to keep abreast of the government updates regarding the CCA scheme to ensure you remain compliant and incorporate the new requirements.

2025 CCA Calendar


Sector-specific targets are still to be determined over the course of the year and currently working to the following schedule:

Now:

  • The Department for Energy Security and Net Zero (DESNZ) is currently developing sector targets based on submitted SATs. 


Early summer:

  • Target proposals will be sent to sectors.

 

Summer:

  • Target negotiations (8 weeks to allow sectors to counter proposals).

 

September:

  • Final target letters sent to sectors.

 

October:

  • Umbrella Agreements sent to sectors.

 

November:

  • Underlying Agreements sent to scheme members.


December:

  • Deadline for members to sign Agreements.


The First Phase 3 Target Period commences 1st  January 2026.
