What is a Low Carbon Energy Assessor (LCEA)?

Low Carbon Energy Assessors (LCEAs) provide Energy Performance Certificates (EPCs), Display Energy Certificates (DECs) and Air Conditioning Inspection Reports.

LCEAs are certified professionals who produce energy assessments in line with the UK’s Energy Performance of Buildings Regulations. LCEAs can be certified in the following report types:

  • Energy Performance Certificate (EPC): An asset rating that assesses the theoretical energy performance of a building. Required when a non-domestic property is constructed, sold, or let.
  • Display Energy Certificate (DEC): An operational rating based on actual energy use. Required for large public buildings (250m²+) frequently visited by the public.
  • Air Conditioning Inspection Report (ACIR). 

All schemes conform to the requirements of  ISO 17024:2012 and registrants must comply with competency requirements, our code of conduct, maintain appropriate insurance and meet our CPD requirements.

Join CIBSE Certification's register of Low Carbon Consultants to demonstrate competence in providing Energy Performance Certificates (EPCs) and Display Energy Certificates (DECs). Our EPC and DEC Assessor competency schemes are the only operating Energy Assessor schemes accredited by UKAS.
