SECR carbon reporting: a guide for UK companies


As part of its push towards greater climate action, the UK government has mandated that large UK organisations must disclose their electricity usage and greenhouse gas emissions alongside their annual financial reports. This requirement is now live for 11,900 firms across the UK, most of which are reporting their emissions for the first time.

This new programme—Streamlined Energy and Carbon Reporting (SECR)—replaces the now-defunct Carbon Reduction Commitment (CRC) Energy Efficiency Scheme. It continues the same mission of encouraging more efficient operations, while expanding the reporting scope to ensure companies are taking real action on carbon. Watershed helps UK companies like Wise and Monzo prepare their SECR filings. We’re sharing here the basics of what you need to know: whom the SECR programme applies to, what it asks for, and how and where to file the resulting report.

Covered organisations

The new obligations cover all UK quoted companies. They also cover private companies and nonprofits that have two or more of:

  1. 250+ employees
  2. £36+ annual turnover
  3. £18m+ balance sheet

What SECR asks for

SECR requires companies to disclose three metrics and two pieces of commentary:

  1. Total energy consumption - Most organisations can calculate this by adding their gas and electricity bills. Unquoted organisations and LLPs must also include fuel purchased for all business travel beginning and ending in the UK.
  2. Scope 1 and 2 greenhouse gas (GHG) emissions - Using the Greenhouse Gas Protocol’s framework, Scope 1 covers direct emissions from company-controlled infrastructure, whilst Scope 2 covers emissions associated with the purchase of electricity, steam, heat, and cooling. These are expressed in carbon dioxide equivalents (CO2e) to normalise emissions of non-carbon greenhouse gases.
  3. An emissions intensity ratio - To put your emissions in context, they must also be expressed relative to some business activity—eg. tonnes of CO2e per dollar of turnover. The chosen ratio (see options in Annex F) must be considered “most appropriate” for your core business activity.
  4. Brief commentary on actions taken - You must list all actions taken in the past year to improve energy efficiency across your infrastructure and operations.
  5. Notes on methodology - You must make it clear how you calculated your consumption, emissions, and intensity ratio.

Metrics 1 and 2 must also include annual totals for the prior reporting year for reference. Quoted companies must disclose metrics 1-3 for their entire global footprints, broken out between UK and non-UK totals. 

How to report

Filing requirements are based on organisation type:
