TrustMark has been working closely in consultation with Scheme Providers to provide an update on PAS2035:2023 Retrofit Design Guidance.

This guidance has been updated to assist the preparation of Retrofit Designs and corresponding documentation, to help comply with the requirements of PAS2035:2023.

It has been prepared by ecmk Ltd in consultation with TrustMark and other TrustMark Scheme Providers including; Elmhurst Energy, The Installation Assurance Authority (The IAA) and Quidos Ltd.

Produced with the support of Nigel Jones at CoreLogic UK, the PAS2035 Design Best Practice Guide has been created to highlight key areas to follow, to help ensure compliance when working with, and producing retrofit designs.

You can view this guide on Assessor Hub or the TrustMark website.
