The Celtic Team
Our skilled labour team is at the very heart of our business and everything we do. We care passionately about our people, and many of our employees have worked continuously with Celtic for more than 20 years.
That loyalty and experience bring stability to our business and help us maintain a progressive, sustainable and positive working environment.
Our culture brings much more to your project than just materials - it brings experience, commitment and people who genuinely care about the work they deliver.

Construction and Project Management
Over the past 30 years, Celtic has built an experienced, highly skilled management team, many of whom have progressed through the business and developed their careers with us. Their combined experience and understanding of Celtic’s standards bring confidence and continuity to every project.

Our Quality, Safety, Health and Environmental team works closely with project teams to maintain robust, site-specific safe systems of work on every project. They also oversee our Integrated Management System and support Celtic’s focus on sustainability, responsible sourcing and industry best practice.

Our Surveying team provides clear commercial control on every project, managing cost, change and financial performance from pre-construction to final account.
