PAS 2030 & Trustmark Accreditations.


What is PAS 2030?

PAS 2030:2019 relates to companies who are installing energy efficiency measures (EEM) in existing domestic buildings or dwellings, sometimes referred to as retrofit or refurbishments.

PAS 2030 is the industry standard that all installers who are installing energy efficiency measures under Government initiatives must meet. The standard sets requirements for different elements of the business, including installer competence, technical knowledge and ability, management systems, skills training and health & safety policies.
