Our PAS 2035 Retrofit Process
We follow a clear, compliant, and customer-focused process to guarantee the best results.
We begin by discussing your goals. A Retrofit Assessor then carries out a detailed survey of your property to gather all the necessary data.
We analyse the assessment findings to create a tailored retrofit plan. This includes an Improvement Option Evaluation (IOE) and a Medium-Term Improvement Plan to suit your budget and ambitions.
Our Retrofit Coordinator oversees the project, organising our installation teams to ensure all energy efficiency measures are fitted correctly and safely.
We conduct a final review of the work, provide you with all necessary documentation and guarantees, and ensure you are completely satisfied with your newly upgraded home.
