Building Control

By working with Quadrant, commercial clients have a single point-of-contact through which Building Regulations approval can be attained. Quadrant have decades of experience providing Building Regulation approval for various commercial clients. These range from small independent entities to large corporations such as Asda, Waitrose and Office shoes. Using Quadrant, commercial clients can feel assured that increasingly complex Building Regulations are being adhered to.

We pride ourselves on providing a first-class Building Control service. From project inception to completion on site, a single-point-of-contact at Quadrant will provide prompt, proactive and practical solutions to save you time and costs. We are able to approve Building Regulations throughout England and Wales saving our commercial clients time and resources contacting each Local Authority for approval.

Each project Quadrant works on is assigned a project manager. We have project managers with decades of experience working with commercial clients on varying projects. Our project managers are here to keep you informed of how to ensure that your project adheres to ever complicated Building Regulations. If you need advice on how to proceed with your build, you can feel assured that we have project managers who are happy to work with you to complete your build to the highest standard.

In addition to our core Building Control service, we also offer:
