Supported by the UK’s Largest EPC scheme
On 1st June 2017 Elmhurst Energy Systems Limited took ownership of iATS. Elmhurst Energy is the UK’s largest accreditation scheme for EPC assessors, which includes non-domestic energy assessors and SAP Assessors. Elmhurst have already started investing more resources into the iATS Scheme and will continue to grow and develop the scheme in the future. 

Links with SAP Assessors
Elmhurst’s SAP EPC software now offers a search facility which allows Elmhurst’s SAP Assessors to search for iATS air testers when they require an air test for their As-Built SAP Calculations. This could result in even more business for  iATS Air Testers.

Search and validation facility (coming soon)
