Ryan Williams, Project Manager, Kier Construction (Western & Wales)

Nolan Commercial have been thoroughly professional throughout the Maes yr Yrfa project and have delivered a quality product in a safe manner. They have embraced our progressive snagging system, with any defects dealt with quickly. As a result of their performance on this project they have become fully incorporated on the Kier supply chain. I would recommend their use to any other contractor and in particular the installation team we have on site.
