With ista, companies gain accurate data, SECR-ready reports and actionable insights that support compliance today and net zero tomorrow.
Introduced in 2019, Streamlined Energy and Carbon Reporting (SECR) was designed to make corporate energy and carbon disclosures in the UK broader, simpler and more transparent. It is designed to provide stakeholders with clearer insights and encourage companies to adopt efficiency measures that reduce costs and emissions.
However, for many organisations, converting fragmented energy data into a compliant SECR disclosure is far from simple. Applying the latest government conversion factors and documenting efficiency actions can quickly become complex and time-consuming.
That’s where ista comes in. Our energy and carbon reporting experts support you through every step of the process, from data collection and emissions calculations to preparing clear, compliant reports. With ista as your partner, SECR compliance becomes straightforward, helping you to save energy, reduce costs, and improve your sustainability performance.
Carbon audits are now mandatory for large UK businesses. Introduced in 2019, Streamlined Energy and Carbon Reporting (SECR) is a mandatory UK reporting framework. It requires large companies to disclose their energy consumption, greenhouse gas emissions and efficiency measures in their annual reports. The aim is to increase transparency, encourage efficiency improvements and support the UK's goal of achieving net zero carbon emissions by 2050.
SECR applies to quoted companies listed on the London Stock Exchange or equivalent markets, as well as to large limited liability partnerships and large UK-incorporated but unquoted companies, provided they meet two or more of the following criteria:
• 250 or more employees
• Turnover in excess of £36 million
• Balance sheet in excess of £18 million
However, many smaller businesses also choose to report their energy consumption and CO₂ emissions voluntarily to strengthen their ESG credentials and demonstrate sustainability leadership.
Companies within the SECR framework must include the following in their annual reports:

The UK has long been a leader in taking action on climate change, introducing policies that cut greenhouse gas emissions, promote sustainability and drive efficiency in business operations. One key initiative is the Climate Change Agreements (CCA) scheme.
CCAs are voluntary agreements designed for energy-intensive industries. By committing to sector-specific energy or carbon reduction targets, businesses can secure substantial savings – up to 90% – off the Climate Change Levy (CCL), a UK tax on non-domestic energy use.
Although separate from SECR, CCAs align closely with carbon auditing. Participants must measure and report energy consumption and emissions against agreed targets, using the same data and processes that underpin SECR compliance.
This makes CCAs a win-win: companies reduce operational costs while contributing directly to the UK’s net zero goals. From 2025, a new CCA framework will strengthen this approach.
Updates include:
Together, SECR and CCAs create a powerful incentive for businesses to improve energy efficiency, cut emissions and unlock measurable financial benefits.
Our custom solutions are designed to help our clients reduce their environmental impact, improve health and safety in their buildings, and save money on energy costs.
