Electrical work in an office
Office electrics follow the desks. When teams grow, move or change how they work, power, lighting and cabinets have to move with them.
An office’s electrical layout is built around its furniture plan: power to desks through floor boxes, desk modules or perimeter trunking, supplies for printers and kitchenettes, dedicated circuits for the comms cabinet, and lighting suited to screen work. When the layout changes, desk positions, partitions and meeting rooms need new or moved supplies, and lighting may no longer line up with the rooms.
Property guides describe how electrical work changes with the type of building it happens in.
Offices sit inside buildings with landlord requirements. Changes to the tenant’s installation usually need landlord approval, drawings and sometimes the building’s nominated contractors for certain work. To avoid disrupting staff, anything that needs circuits switched off is normally planned for evenings or weekends.

04Questions
Questions people ask
- Why does the kitchenette keep tripping?
- Kettles, coffee machines and microwaves running together can overload a circuit sized for less.
- Can floor boxes be moved?
- Often, depending on the raised floor or screed and where the supply cables run.
- Should the server cabinet have its own circuit?
- Yes. A dedicated circuit stops a fault elsewhere switching off the network.
- Do small changes need landlord approval?
- Many leases require it for any change to the electrical installation; check yours.
