Lighting & Electrical - Commercial Fit-out First and Second Fix

Review the subcontract scope and main contractor's programme. Confirm first-fix start date and the expected second-fix window.

Place purchase orders for first-fix materials - containment, cables, back boxes - with confirmed delivery date aligned to the programme.

Install trunking and conduit, pull cables, fix back boxes, and make distribution board connections before plastering begins.

Complete a first-fix record on site noting what is installed, deferred, and any scope variations. Agree sign-off with the main contractor and raise the first-fix stage invoice.

Place purchase orders for second-fix accessories once the programme date is confirmed. Check delivery lead times against the second-fix window.

Fit socket fronts, switch plates, light fittings, and consumer unit accessories. Make final connections after decoration is complete.

Complete testing and issue the Electrical Installation Certificate. Submit O&M documentation and handover pack. Raise the final invoice with certification attached.

We don't have a clear record of what was completed at first fix, so when we return for second fix weeks later the crew is working from memory or calling the site manager.

Materials for first and second fix are often ordered together but delivered separately, and we lose track of what's on site and what's outstanding when the second-fix crew arrives.

Raising the milestone invoice for each phase relies on someone in the office knowing the site has hit the right stage - which means we often invoice late or miss stage payments entirely.
