Electrical installation in Nairobi spans everything from a new maisonette in the suburbs to an office fit-out in Westlands, and in older buildings across the city the problems are familiar: undersized or brittle old cables, fuse boards from decades ago, missing earthing, sockets overloaded with adaptors and breakers that trip whenever the kettle and microwave run together. In newer buildings, rushed work by unqualified fundis can be just as risky.

Nerpax Systems provides electrical installation, rewiring and inspection across Nairobi County for homes, apartment blocks, offices, shops, schools and light industrial premises. We start with a site survey, then supply quality materials and install to the Kenyan wiring regulations, with correctly sized circuits, proper earthing and a modern DB board.

Serving Nairobi

Nairobi packs almost every kind of property into one county: office towers in the CBD and Upper Hill, apartment blocks in Kilimani and along Thika Road, leafy compounds in Karen and Runda, and busy industrial yards off Mombasa Road and in Industrial Area. Each brings its own worries. Landlords need intercoms, access control and CCTV covering shared entrances, businesses want cameras they can check from a phone, and homeowners want gates, fences and alarms that work when the area loses power. Frequent KPLC interruptions also make UPS units, inverters and generator changeovers a common request. Nerpax Systems serves the whole county with supply, installation and delivery.

Electrical Installation in Nairobi: FAQs

Do you do office electrical fit-outs in Nairobi?

Yes. We plan lighting, power sockets, data points and dedicated circuits for equipment such as servers and air conditioning, working around your layout and timeline. Where the building is occupied, we can schedule disruptive work outside business hours by agreement.

My older Nairobi house still has a fuse board. Should I upgrade?

In most cases, yes. Old rewireable fuse boards lack modern protection such as RCDs, which cut power when there is a risk of electric shock. We inspect the board and wiring, then recommend a board upgrade alone or with rewiring of any unsafe circuits.

Can you wire a new apartment block in Nairobi?

Yes. We work alongside your contractor from conduit and first fix through to boards, final connections and testing. Each unit gets its own board and protection, with common areas on a separate landlord supply. We plan meter positions and risers early to avoid rework.
