Electrical installation in Kiambu is under real pressure as the county builds at pace, from apartment blocks in Ruiru and Juja to family homes around Kikuyu, Limuru and Kiambu Town. The weak point in many of these projects is the wiring, and work done by an unqualified fundi can leave undersized cables, missing earthing and boards that trip constantly, problems that stay hidden until something burns.

Nerpax Systems is a Kiambu-based team providing electrical installation, rewiring and inspection across the county. We survey the site, plan circuits around how the building will be used, then supply quality materials and install conduit, cabling, DB boards, lighting, sockets and earthing to the Kenyan wiring regulations. Every circuit is tested before handover.

Serving Kiambu

Kiambu is home ground for Nerpax Systems, with our base in the Kikuyu area. The county stretches from fast-growing satellite towns such as Ruiru, Juja and Ruaka to tea estates around Limuru, dairy farms in Githunguri and the factories of Thika. That mix shapes the work: rental blocks and student hostels need CCTV, intercoms and well-planned wiring, family homes in new estates want automated gates and electric fencing, and farms far from the main roads lean on solar pumping and backup power when the grid drops. Contractors building across the county also need materials delivered and panels fitted on schedule. We supply, install and deliver throughout Kiambu.

Electrical Installation in Kiambu: FAQs

Do you handle electrical work for both new builds and old houses in Kiambu?

Yes. For new builds we work with your contractor from first fix through to final connection and testing. For older homes we inspect first, then rewire fully or in parts depending on what we find. Both follow the Kenyan wiring regulations and end with testing and a clear handover.

Can you work with my contractor on a building site in Kiambu?

Yes. We coordinate with the contractor on when conduit and boxes go in before plastering, and when second fix and testing happen. Planning the electrical work early avoids chasing finished walls later and keeps the project on schedule.

Is it worth inspecting a newly built house before moving in?

Yes, especially if the wiring was done quickly or you do not know who did it. An inspection checks earthing, protection, cable sizes and workmanship. It is far cheaper to correct problems before you move in and furnish the house than after a fault appears.
