Paul and I worked on my Abbey Wharfe development of 24 apartments in Selby. Paul was the project manager for the main contractor. I always found Paul honest, reliable, hardworking and professional. He ensured that the development was finished both on time and at the original cost estimate. I would certainly recommend Paul as a project manager for any future projects that you may have.

I previously worked with Paul on one of the largest solar install projects in Europe. Working above one of Europe’s largest manufacturing / assembly lines The project consisted of three main activities. 1) Removal of existing asbestos roof 2) Installing new high tech cladding system 3) Installing new solar arrays. Due the size and complexed nature of this project. Someone with great experience in managing a large project was essential. Paul was responsible for the immense planning and execution. During the time I spent working on this project. Paul, displayed excellent skills in handling challenges and maintaining quality standards. It was a pleasure work with Paul and some of his method used, I’ve since implemented on my projects I’d class Paul as a true professional, who is passionate about his projects and is valuable asset to the growth of any company he’s involved with.
