The importance of 3rd party guarantees

Introduction

Host Adam Armour-Florence is joined by industry experts Andrew Champ and Mitch Gee from SWIGA to explore the critical role of third-party guarantees in retrofit projects.

Drawing on decades of experience in construction and external wall insulation, the guests unpack what 3rd party guarantees are, why they matter, and how they protect both homeowners and project stakeholders. The discussion highlights key challenges in the retrofit sector, including subcontracting risks, inconsistent quality standards and the need for better data sharing across certification and guarantee providers.

Andrew and Mitch also share practical insights from large scale programmes such as social housing decarbonisation schemes, demonstrating how early engagement with guarantee providers and robust quality assurance processes can lead to consistently successful outcomes. They challenge common misconceptions around failure rates in insulation projects, emphasising that with the right checks and accountability in place, high-quality delivery is not only achievable but already being demonstrated.
