Electrical Design for Shop Fit-Out (UK BS7671)

Project Overview:
We require a professional electrical design for a commercial shop fit-out in Walton-on-Thames, UK. The design must comply with BS7671:2018+A2:2022.
A full CAD drawing will be provided with all zones, circuits, and equipment clearly plotted and identified. Your job will be to carry out the technical design and calculations based on this information.
Scope of Work:
• Load calculations based on provided appliance and equipment schedule (e.g. 3-phase coffee machines, fridges, tills, lighting).
• Cable sizing (including voltage drop, grouping, and installation conditions).
• Circuit design and protective device specification (MCB/RCD/RCBO).
• Distribution board schedule.
• Earthing and bonding per BS7671.
• Annotated layout showing cable routes and circuit numbers (you can build off the provided CAD).
Circuit Requirements:
• Multiple radial socket circuits
• Two lighting circuits
• Each 3-phase outlet on its own individual circuit
Files Provided:
• CAD floor plan (with zones, devices, and boundary already mapped)
• Equipment/power schedule
Deliverables:
• PDF with full electrical design and circuit layout
• DWG/DXF CAD output with annotated circuits
• Load schedule and distribution board schedule
• Cable and protection specifications
Timeline:
• Preferred turnaround: 3–5 working days
