Make one current layout
Bring furniture, lighting, appliance and cabinet decisions onto the same drawing. Mark sockets, switches and fixed equipment in relation to the final room, not an old layout that another trade has already changed.
Include how the lights should operate and which equipment is being retained. A fitting chosen late can change a driver, support or connection requirement even when the visible position stays the same.
Plan access for first fix
Plan access for first fix
Before plasterboard, plaster, floors or cabinets close the routes, agree which areas must remain accessible. First fix is part of the wider build sequence; it is not simply a date to install every finished accessory.
Existing electrical arrangements can affect access and safe isolation during the build. Agree affected circuits and interruptions with the project team before work disturbs those systems.
Define what must be ready for second fix
Define what must be ready for second fix
Agree the condition of walls, ceilings and cabinetry needed for fitting accessories and connecting the specified equipment. Tell Max when supplied fittings or appliances will actually be available.
A delayed worktop or changed appliance can affect electrical completion. Keep one contact responsible for communicating changes, and agree how variations to scope and cost will be discussed.
Reserve time for completion
Reserve time for completion
Allow for testing, checks and completion records after installation. Include that stage in the programme before the rooms are handed over, rather than treating visible fitting as the end of the electrical work.
Ask which installation certificate and any Building Regulations notification are relevant. They are distinct from a periodic EICR and should match the work that has actually been completed.
Your planning checklist
- Latest room and furniture drawing
- Appliance and light specifications
- First-fix access dates
- Room readiness and product delivery for second fix
- Testing, handover and making-good responsibilities
Questions answered
What is the difference between electrical first fix and second fix?
First fix prepares the agreed wiring routes and positions while the building is accessible. Second fix fits the selected accessories and equipment when the room is ready. The exact tasks depend on the project, and completion also needs the appropriate testing and records rather than stopping at visible fittings.
Ask Max about thisWhich electrical choices must be made before plastering?
Settle socket and switch positions, light locations and controls, and fixed-appliance requirements. Use the final furniture and cabinet layout wherever possible. Product details can affect supports, drivers and connections, so mark remaining decisions clearly instead of allowing an outdated drawing to become the installation plan.
Ask Max about thisCan I move sockets after the electrical first fix?
A position can often be revised, but installed routes and finished surfaces determine the extra work. Changes may reopen plaster or flooring and alter the programme. Raise the change before further work closes the route, then agree its effect on the price and timing.
Ask Max about thisWhat needs to be ready for the electrician at second fix?
Agree the required state of walls, ceilings and cabinetry, and confirm that the specified fittings and appliances are available. Share any delays or model changes before attendance. The electrician can then coordinate final installation, connection and testing with the actual room condition rather than an assumed completion date.
Ask Max about thisIs an EICR the normal certificate after a new electrical installation?
An EICR reports on the condition of an existing installation; it is different from the installation certification for new work. Ask which records and any Building Regulations notification apply to the agreed project. Keep the completion documents together with the specification and any equipment instructions.
