First fix and second fix for kitchen rewires

How first fix and second fix are sequenced around the kitchen fitter, walls, cabinets and finished accessories.

Kitchen rewires are usually split around the renovation. First fix sets cable routes and back boxes before the walls and cabinets close in; second fix fits and checks the finished accessories once the kitchen is ready.

How the sequence usually works

  • Confirm the kitchen layout, appliance plan and likely routes before first fix.
  • First fix the agreed cables, boxes and positions before plastering, tiling or cabinet installation blocks access.
  • Return for second fix once surfaces, cabinets and appliances are ready for the finished sockets, switches, isolators and lighting.

What helps the sequence stay tidy

  • Clear fitter dates and a shared understanding of when walls, tiles and cabinets will be closed.
  • Final appliance and accessory choices before positions are fixed.
  • Enough access for testing, second fix and handover at the end.

What can change the scope

  • If first fix is missed or access is closed early, the electrical route may need re-planning.
  • Late changes to cabinet layout, splashback height or appliances can require extra work.
  • Older wiring or poor previous work found during strip-out can change the agreed route.
