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.

​​

I seek to serve clients at the lower end of the ESOS 'spectrum': those with up to around 500 employees or up to a dozen business locations.    However, my experience extends through all forms and types of organisation, including​

​

  • Large manufacturing, including pharmaceuticals and food

  • Logistics, including maritime

  • Education

  • Care sector and medical buildings

  • Retail and trade counter

  • ​Motor trade and dealerships

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 

​
