SECR: 40MWh is equivalent to around 9 houses worth of electricity or 4 houses worth of gas.

The exemption for large companies to deliver annual SECR returns is only 40,000kWh. Most large companies will be significantly above this when accounting for electricity, gas and vehicle fuel.

Streamlined Energy and Carbon Reporting (SECR) is aimed at encouraging companies to benchmark and then reduce their energy and fuel use and so reduce greenhouse gas emissions (and by doing so, improve their profit margins).

It also includes fleet fuel use, so if you meet two of these three conditions

  1. More than 250 employees
  2. Annual turnover £36m or greater
  3. Annual balance sheet total £18m or greater;

…then less than 4,000 litres of annual diesel consumption would be sufficient to put your company above the exemption threshold. That’s equivalent to roughly one company car travelling around 35,000 miles.

It became law in the UK on 1st April 2019 and will mandate almost 12,000 companies to assess and publicise their energy, fuel and carbon emissions data, every year henceforth.
