Supply Chain Advice Pack: Costing retrofit projects

Introduction

Homes have become the second highest emitting sector in the UK1 and the cost of decarbonising them is substantial: “The CCC estimates that an investment of about £250 billion will be needed to fully decarbonise homes by 2050, the equivalent of about £9 billion each year from the late 2020s to 2050” (House of Commons, 2022)2.
