Our Certified PAS 2030 Installers

Welcome to our directory of certified contractors. Each installer listed here has been independently assessed and certified by NetRet Group Ltd to meet the requirements of PAS 2030:2023 – the industry standard for the installation of energy efficiency measures (EEMs) in existing dwellings.

These businesses have demonstrated their commitment to quality workmanship, regulatory compliance, and customer service. They are authorised to deliver work under government-backed schemes such as ECO4 and the Great British Insulation Scheme, and each holds TrustMark registration where applicable.

Our certification process is rigorous, transparent, and fully aligned with UKAS-accredited standards. We update this list regularly to ensure only compliant and current installers are shown.

Whether you're a homeowner, principal contractor, or retrofit coordinator, you can trust that all installers featured here meet the highest standards of energy efficiency retrofit delivery.
