What is a Low Carbon Consultant (LCC)?

Low Carbon Consultants (LCCs) are recognised experts in reducing carbon emissions in buildings through smarter design, operation, compliance and simulation. 

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 minimising energy use and carbon emissions from buildings both in design and operation. This enables you to go beyond the current legal minimum in improving the energy performance of both new and existing buildings.

Clients can be assured that buildings designed and operated by LCCs will meet the requirements of Approved Document L Volume 2 2021 and Building Control Officers can be assured that compliance is being signed off by suitably qualified professionals. Registrants of the LCC Register have undertaken assessments to demonstrate their competence.

“Although legislative deadlines and the demand for assessors drive our business targets, it’s the quality industry experience, quality training and completing a rigorous quality assessment procedure that is what all our Low Carbon Energy Assessors and Low Carbon Consultants can pride themselves on”.
