If you require an ESOS Assessment to be Undertaken please contact us for a no obligation discussion.
ESOS is a mandatory energy assessment scheme for organisations in the UK that meet the qualification criteria. The Environment Agency is the UK scheme administrator. Most of the below is cut and paste from the ESOS Guide.
You qualify to be subject to ESOS id you are a large undertaking:
any UK company that either:
an overseas company with a UK registered establishment which has 250 or more UK employees (paying income tax in the UK)
For the purposes of calculating your total energy supply, which is done to identify your areas of significant energy consumption, you only need to consider input energy. Only include heat where you are importing the heat to your site or process. Where the heat is obtained by converting another source of energy such as gas into heat (on site) then exclude the heat produced to avoid double counting. However please note that all heat must be included in your audits and energy profiles.
All energy use in buildings is included in ESOS. In relation to multi-tenanted buildings and landlord-tenant relationships, under ESOS the responsibility to include energy within an organisation's total energy consumption calculation is determined by whether the participant is; supplied with that energy and consumes that energy by the assets it holds or by the activities it carries out.
Items that do not need to be included in the calculation of total energy consumption include show homes or the office building under construction where you use grid electricity in the building during the construction of it but which you will no longer have responsibility for on the compliance date. However, if you are using generators on sites then you must include the input fuels in your total energy consumption if you hold them on the qualification date and the compliance date.
ESOS participants may also be part of other energy management/reporting schemes, like:
Please note that simply being part of these other schemes does not automatically count as ESOS compliance for the energy covered by those regimes. You can use energy data you collect as part of your compliance with these schemes to calculate your total energy consumption for your ESOS Assessment but you are likely to have to do additional work to ensure you are also compliant with ESOS.
You must carry out site visits as part of your ESOS energy audit, but you don't have to visit every site where large undertakings hold more than one site. You must make sure you've collected and analyzed data for all your areas of significant energy consumption regardless of the number of site visits.
Organisations with multiple sites or assets that are identical or very similar can take a proportionate approach and apply the energy saving opportunities identified in their site visits to their wider portfolio. The lead assessor and participant organisation should determine a suitable site visit sampling approach to reflect the energy consumption patterns oft heir assets and activities.

The Energy Savings Opportunity Scheme (ESOS) is a mandatory energy assessment requirement for large undertakings in the UK. Managed by the Environment Agency, it seeks to identify cost-effective energy saving measures across buildings, industrial processes, and transport. Organisations must determine their qualification based on employee headcount or financial turnover to avoid non-compliance penalties.
Determining whether your organisation falls under the ESOS mandate is the first step in the compliance cycle. Large undertakings typically include any UK company with 250+ employees or significant annual turnover and balance sheet totals. Understanding your "Total Energy Consumption" (TEC) is vital, as this data forms the foundation of your assessment and identifies "Areas of Significant Energy Consumption" (ASECs) that require detailed auditing.
A core component of a compliant ESOS assessment is the energy audit, which must be overseen by a qualified Lead Assessor. While not every site within a large portfolio must be visited, a proportionate sampling approach must be used to ensure the data is representative of the organisation's overall energy profile.
Managing ESOS compliance is often part of a broader carbon strategy or net zero roadmap. By aligning these mandatory assessments with Energy Statements and corporate sustainability goals, businesses can transform a regulatory burden into a driver for operational efficiency. At SWEL, we provide the technical authority required to guide your organisation through the complexities of UK energy legislation, ensuring both compliance and long-term cost reduction.
