Retrofit Glossary for Warm Homes Delivery

Introduction

Clear and accessible communication is essential in retrofit projects, where technical terms and acronyms can easily create barriers for residents and delivery teams. This glossary has been developed to offer consistent, residentfriendly explanations of key terms used across the Warm Homes programme. It provides simple definitions relating to energy performance, building fabric, heating systems, assessment processes, and project delivery, helping to strengthen understanding at every stage of the retrofit journey.

By using everyday language that focuses on comfort, cost savings and practical outcomes, the glossary makes it easier for residents to engage with proposed measures and supports clearer communication from project teams. The aim is to reduce confusion, build trust and ensure the benefits of retrofit are understood by everyone involved.
