Robust Solution

ESOS Auditor was developed in conjunction with the Energy Managers Association and reviewed by Kit Oung the Technical Author for the new ESOS standard PAS 51215: Energy efficiency audit - Competency of a lead energy auditor.

If you are chosen for Audit by your regulator, e.g. the Environment Agency, ESOS Auditor is now accepted as part of your Evidence Pack. The tool enables you to build, store and track the data required for your Evidence Pack online helping give you 100% assurance that it is complete.

We have relationships with all the main ESOS Registers and provide discounts to companies using Lead Assessors registered through these schemes.

Team Connectivity

The ESOS Auditor platform is completely scalable across any size and type of organisation structure. You can have any number of users across multiple sites, and set different levels of access. You can also limit auditing capabilities to your Accredited Lead Assessor.

Key users can also track progress, identify data gaps and produce reports suitable for ESOS Compliance. You can also easily review and prioritise energy efficiency recommendations to find the most cost effective opportunities for you based on automatically calculated ROI.

All Energy Types

ESOS Auditor enables you to upload, store, manage and audit energy data from across all of your energy types: buildings, transport and industrial/commercial processes. You can create energy supply information and allocate different percentages to the relevant buildings or processes.

A specific bulk upload function and enhanced filtering allows you to bring in all the data that you may have already compiled in spreadsheets or other sources as part of previous energy audits or as part of ISO 50001. The platform automatically works out daily usage and also allows you to can attach evidence documentation to each entry.

The platform also allows you to add custom metrics which can be applied to your Buildings and Processes. Ensuring that you can pull reports and filter information based on the internal metrics important to you.

ESOS Compliant

ESOS Auditor is designed specifically to meet all ESOS requirements and enable easy and quick compliance and reporting. The software enforces ESOS rules, ensuring that the collation of data is done correctly first time and that the Lead Assessor is presented with the full complement of required data prior to the Audit.

By allowing access to the appointed ESOS lead Assessor the solution enables all consumption data to be checked for consistency and completeness and for all cost-effective energy efficiency recommendation to be collated and reviewed ready for final reporting. In addition, the final report format is consistent with ESOS requirements, including Life Cycle Assessment.
