This document summarizes a report on barriers to whole home energy efficiency retrofits in the UK. It identified over 400 financial and non-financial barriers grouped into 8 categories: economic, education/skills, political, consumer, coordination/supply chain, installation issues, performance, and pilots. The report aims to break down these barriers by creating an industry action plan focused on developing a vision for retrofits, implementing whole home retrofit delivery plans, and improving consumer information through working groups. The goal is to increase demand for whole home retrofits to help industry growth and for the UK to achieve energy efficiency targets.
