EXPERT ESOS LEAD ASSESSOR FOR
ESOS REPORTING.
ESOS REQUIRED?
READ THIS.
The Energy Savings Opportunity Scheme (ESOS) is a mandatory energy compliance scheme impacting 12,000 UK businesses.
ESOS Phase 3 corporations must now report on progress annually, and submit their reports by December 5th each year, and the Phase 4 submission is due on 5th December 2027.
The potential fines for non-compliance are £500 per day plus civil penalties, and the new Environment Agency demands quadruple your risk.
Businesses with more than 250 employees or those which meet both the following financial criteria on 31st December 2026, are required to comply with ESOS:
- Annual Turnover: > £44 Million
- Balance Sheet Total: > £38 Million
All organisations within a corporate group must comply if at least one UK group member meets the criteria above.
We’re ready to help. Shall we start?
WHAT IS THE COST
OF ESOS COMPLIANCE?
REJECT OUTRAGEOUS FEES – OUR FEES FROM ONLY £3,500
With the shortage of Lead Assessors, fees for most businesses tend to be in the range of £9,000–£25,000, and as high as £50,000 for large manufacturing businesses.
The government estimates that the additional cost of adding the Net Zero element for Phase 5 onwards will be as high as £7,500 per audit.
Especially for “white collar” businesses, often in leased buildings, there is limited scope for energy reduction, and behavioural changes take priority. In these cases, transportation costs are often critical.
ESG Pro take a highly scaled approach resulting in fees which start as low as £3,500 per year, and we use the research to create the core narrative for your SECR and PPN 06/21 and PPN 006 reports.

COMPREHENSIVE SERVICE.
USE ESOS TO REDUCE COSTS.
The Energy Savings Opportunity Scheme is designed to help businesses identify energy consumption measures, whether that’s through reduced electricity or gas consumed, to optimising their vehicle fleet, upgrading plant and machinery, and more.
Unlike the SECR which is focussed on carbon emissions, ESOS examines kilowatt hours. They go hand in hand, however, and ESG Pro’s experts will simplify these processes. However, quality ESOS reporting and implementation of our bespoke ESOS Action Plan can deliver a huge reduction in your overall carbon emissions!

HOW TO FUND YOUR
ESOS ACTION PLAN.
Comply without breaking the bank.
Progress against your ESOS action plan commitments must be included in the ESOS assessment, and you are required to act upon your ESOS audit recommendations.
Comply or explain! If your business decides not to carry out any of the recommended measures, you have to explain why – and this disclosure is made public.
Our procurement specialists and Lead Assessors work together to identify opportunities for a ‘shared savings’ energy efficiency scheme, whereby the upfront cost of an energy saving project is covered.
This means that energy efficiency projects can be cost neutral for an organisation, while bringing savings in the long term through lower energy bills.
It’s just another approach by ESG Pro to help businesses comply without breaking the bank!
