Supply Chain Advice Pack: Introduction to PAS 2030

Introduction

The PAS 2030:2023 (Publicly Available Specification) ensures high quality, compliant installation of energy efficiency measures in existing homes. Its aim is to ensure that retrofit activity delivered in UK homes delvers the sustainability performance outcomes that the works should provide.

Energy efficiency installers delivering large scale retrofit works will benefit from being certified to and maintaining compliance with PAS 2030 for each of the energy efficiency measures that they wish to install.

PAS 2030 guidance outlines the requirements for competence, technical ability, and overall quality requirements that all installers must follow to meet the necessary standards and maintain quality of works. It should be used in complementarity with PAS 2035 to enable lodgement into the Trustmark data warehouse and compliance with grant funding conditions.

PAS 2030 certification can be gained by installers of retrofit measures and is required on a measure-by-measure basis, meaning a contractor can hold certifications for a single measure in isolation or a suite of measures.
