• Wrote a full RAMS to Willmott Dixon's acceptance checklist, revised once to close every comment, for a two man crew working over about two weeks in phases from 28 July 2025.
• Small block: installed four external 25 x 3 mm PVC coated aluminium down conductors on the finished brickwork from roof to 600 mm above ground, each with a test clamp, and drove a copper bonded earth rod at the base of each under a permit to dig and a CAT scan.
• Large block: traced the five cast in tapes, extended the two mansard tapes up behind the new zinc cladding before it was closed, and tested each for continuity to the foundation before accepting it as a down conductor. Where the structure could carry current we bonded the steel at roof and ground level with M10 clamps at about 20 m spacing.
• Installed the roof network after the parapets were finished but before the handrails went in, adding a cross conductor so no roof area exceeds 20 m, and bonded the solar panel frames, satellite dishes, plant and steel roof hatch frames.
• Ran a full continuity and resistance test on every down conductor and electrode with a calibrated digital earth tester and issued a Lightning Protection Test Certificate.

Both blocks brought to a complete, tested system: four new down conductors and earths on the small block, and the large block's cast in conductors verified, extended and earthed. The test certificate was issued to the client.
