My name is Richard Weaver. I am a fully accredited freelance ESOS Lead Assessor and I trade under the name Enercert.
I have undertaken many hundreds of site surveys through ESOS phases 1, 2 and 3, as employee, contractor and as direct consultant.
My services are best suited to ESOS participants at the lower end of the scale: 250 to 1000 employees or less than 15 to 20 sites. However, my experience extends through all forms and types of organisation.

ESOS Phase 4
'Phase 4' is the fourth iteration of ESOS, the first being 'Phase 1' in 2014.
Thanks to the enforcement activities of the Environment Agency , most of those falling into the requirement for Phase 4 will have undertaken Phase 3, and should therefore be familiar with the basics of the ESOS 'process'.
The best preparation for Phase 4 is to begin early in the accumulation of energy consumption data for all sites, activities and transport. This data will be analysed and transcribed by the Lead Assessor.
This consumption data must cover a continuous 12-month period which includes the 31st December 2026. The chosen 12 months could be the calendar year 2026, or as chosen by the organisation, such as an accounting or academic year.
As with Phase 3, an online "Notification of Compliance" is required.
