“The East Midlands project has been one of the most high profile and logistically challenging contracts Colas have ever undertaken in the UK, and having everyone working together to ensure we delivered the outputs and quality required has ensured a fantastic outcome in completing in just 5 weekends.

We are delighted with the finished product. I would like to personally thank you all for the effort and commitment that you all provided for the East Midlands project over the past five weekends. All of your staff were great lads and working the long hours over the weekends they all performed admirably.”

As a preferred subcontractor of Aggregate Industries, Celtest have undertaken both site and laboratory testing on most of our major build schemes across the UK with great success. They have a good technical skill base and excellent site knowledge, from the guys in the office to the technicians on site. They're always there when you need them and a pleasure to work with.

''We have worked with Celtest regularly for over twelve years making use of their site testing and laboratory services. They are our first point of call as they always provide a professional, efficient and friendly service''

“I was first introduced to Celtest more than 30 years ago when I was manager of an analytical chemistry department. Since that time, the industry has changed vastly, mainly in response to new legislation, new construction practices and materials, and constantly updated testing protocols. Celtest has met all of those challenges with dynamic continued professional development to the present day, such that they offer a much broader scope of accredited, state-of-the-art testing, related to construction,  and civil engineering issues,  all with a rapid response and competitive pricing, whilst still maintaining their inherent values of friendly approach-ability”

Since their inception in 1980, I have had the privilege of seeing Celtest grow from a company with only four employees including the current directors, to now being able to provide unsurpassed technical knowledge and services. I and the companies that I have served have benefited hugely from their expertise. They can always be relied upon to provide excellent advice on some of the most complex of material testing issues.
