Everything you need to specify protection correctly.
Standards, design guides, calculators, datasheets and training for lightning protection, earthing and surge protection. Written by the engineers who design the systems, and linked to the solution and product each topic belongs to.
Four doors into the library.
Each door leads to working material, and every page links on to the LPES solution and product family it supports.

Read the storiesThe six questions we are asked most.
| Your question | Read this first | Then go to |
|---|---|---|
| Does my building need lightning protection by law? | Standards & Compliance | Risk Assessment |
| What earth resistance value do I need? | FAQ: earthing | Global Earthing System |
| Which SPD goes in which panel? | SPD Selector | Surge protection by zone |
| How far apart should air terminals and down conductors be? | Design Tools | Flat roof lightning protection |
| How often must the system be inspected and tested? | Standards & Compliance | Periodic inspection and testing |
| I have a tender BOQ to respond to this week. | BOQ / Tender Support | Downloads & Datasheets |
Tell us what you are working on. An engineer will point you to the right document.
Send the drawing, the BOQ line or the question. We reply with the reference and, where it helps, a short note on how it applies to your site.
