steps in our works

Low Carbon Box seek to work within the team and advise along the way to provide assurance of the expected outcome within the required budget, rather than just 'assess' the information and hope for the best. Here is our general approach:

Initial design advice

Using our input at initial design advice provides comfort and integrates an agreed specification to allow the detail design to be completed without unnecessary changes.

Extra Input

We calculate daylight calculations and measure all thermal bridge values along with providing templates for all project types to help you along the way..


We do not watch the clock or leave emails and calls unanswered. We are here to support you and want to share your success in your project.


Your project handover requires a lot of information. We will do everything we can to meet your deadline and provide what you need on time, every time.

What our customers think

I would like to pass on our thanks and appreciation for your hard work, expertise and valued input to the scheme.James Nellist, Lindum Construction
