​Design and Consultancy

​​​The Pre-Construction Services Agreement (PCSA) stage has become essential for achieving Gateway 2 compliance under the Building Safety Act 2022. This legislation requires rigorous building control approval from the Building Safety Regulator (BSR) before construction can begin on Higher-Risk Buildings (HRBs). By appointing contractors early through a PCSA, they can take the lead on design development and compile the documentation needed for Gateway 2, ensuring that safety is fully integrated into the project ahead of the “hard stop” approval point.

​
Our Design & Consultancy team supports projects across lightning protection and earthing, with a strong focus on early engagement at PCSA stage and Gateway 2 compliance.

Delivered by our ATLAS-accredited designers, our services include:

Lightning Protection Risk Assessments (BS EN 62305)​
Fully compliant lightning protection design
Earthing design and calculations
Technical drawings and submittals
Design coordination and consultancy throughout the project lifecycle
Support with Gateway 2 submissions

With increasing regulatory requirements, early and accurate design input is critical to avoid delays, redesign, and compliance risk. We work closely with clients from the earliest stages to deliver practical, compliant, and buildable solutions tailored to each project.
​
If you're working on a project and require support at PCSA stage or beyond, we’d be happy to assist.
