O’Reillys have dealt with all of our projects in a very professionally manner from design stage right through to on-site installation, they would be one of our preferred suppliers and we would no hesitation recommending them for any similar works.”

-Pat Connolly, BAM Contractors

“We recently worked with O’Reilly Concrete on both Blackfriars Road and Woodberry Down, London.
For both of these projects ORC replaced the original RC Column design with a Precast alternative solution which had significant impact in reducing our construction time and labour costs for both projects.
They carried out their scope of works with an outstanding level of service from design stage through to site delivery.
We would highly recommend O’Reilly Concrete UK for any precast solutions and look forward to working with them in the future”
