Introduction — Why correct wiring matters (and why GossTech)
Electricity is the lifeblood of the modern home: lights, refrigeration, charging, entertainment, and essential appliances all depend on safe, correctly installed wiring. Faulty or aging wiring is one of the top causes of household fires, frequent power trips, poor appliance life, and expensive energy waste. That’s where GossTech comes in.
At GossTech we combine certified electricians, modern testing equipment, and clear communication to deliver household wiring and rewiring services across Nairobi and throughout Kenya. Whether you’re building a new home, renovating an older property, or experiencing persistent electrical faults, our teams design and install safe, efficient wiring systems that last — and we back our work with professional aftercare and fast response times.

How we work — our process (clear, safe, and transparent)
We follow a predictable, safety-first workflow so you always know what to expect.
- Initial call & site visit
Call 0723613664 or email info@gosstech.co.ke — we arrange a convenient site visit. Our electrician conducts a visual inspection, checks the distribution board, and lists visible issues. - Load assessment & quote
We perform load calculations, identify required circuits, and prepare a written quote that includes materials, labour, expected timeline, and safety tests. - Scheduling & prep
We agree on a start date. For rewires that require outages, we explain how long power will be off and suggest temporary arrangements. - Work execution
Certified electricians perform the wiring or rewiring using quality materials, labeled circuits, and tidy cable routes (concealed or surface as requested). We maintain a safe worksite and protect floors/ finishes. - Testing & handover
After installation we conduct full testing (insulation, polarity, Earth continuity, circuit performance), produce a test report, and issue recommendations for user care. - Aftercare & warranty
We provide a warranty period on workmanship and respond to follow-up calls. We also offer periodic inspection packages.

Major Nairobi estates & neighbourhoods we serve:
Westlands, Kilimani, Kileleshwa, Lavington, Parklands, Garden Estate, Parklands/Highridge, Gigiri, Muthaiga, Loresho, Ridgeways, Runda, Karura, Roysambu, Kasarani, Zimmerman, Thome, Mathare, Kale, Umoja, Eastleigh, Pangani, Ngara, Nairobi CBD, Upper Hill, Luthuli Avenue, Embakasi, Embakasi South, South B, South C, South C Estate, South C Industrial Area, Lang’ata, Karen, Rongai (Ngong Road / Kiserian corridor), Kibera, Dagoretti, Kabiria, Kawangware, Westlands, Nairobi West, Industrial Area, Ngong Road, Kilimani (Baraka, Hurlingham nearby), Parklands, Kilimani, Donholm, Buruburu, Kayole, Dandora, Umoja, Kasarani, Roysambu, Roysambu, Roysambu North, Roysambu South, Kibera, Soweto Kayole, Zimmerman, Highridge — and every other estate, lane, and household in the city.
Summary of what we do in Nairobi: From one-off socket installations in Kilimani to full-house rewires in Karen, inverter-ready wiring in Embakasi, and commercial-residential hybrid installations in Upper Hill and the CBD — our Nairobi teams provide tailored solutions, fast response, and local knowledge (network supply quirks, typical building materials, and estate security arrangements) to minimize disruption.
Other counties & towns across Kenya (we serve nationwide)
We undertake projects across Kenya through our regional teams and trusted partners. Common counties and towns we serve include (but are not limited to):
- Western Kenya: Kisumu, Siaya, Busia, Kakamega, Bungoma — domestic rewires, consumer unit upgrades, solar-ready wiring.
- Central & Rift Valley: Nakuru, Eldoret, Nyeri, Nanyuki, Kericho — new wiring for new homes, rural earthing improvements.
- Coastal Kenya: Mombasa, Kilifi, Malindi — corrosion-aware installations, moisture-resistant routing, protective enclosures.
- Eastern & Northeastern regions: Machakos, Kitui, Meru — off-grid ready wiring and inverter circuits for unreliable grid supply.
Summary for nationwide work: In towns outside Nairobi we adapt to local network conditions, available materials, and accessibility. We partner with local electricians for logistics, while our senior electricians handle design, testing, and final sign-off.
Area-by-area service breakdown (table)
Below is a condensed, practical breakdown showing core services we provide to households in different types of areas.
| Area type | Typical services provided | Why our service is important there |
|---|---|---|
| Central Nairobi suburbs (Kilimani, Kileleshwa, Lavington) | Full rewires, high-end lighting, smart home integrations, dedicated appliance circuits | Older homes, renovations, and smart-home upgrades demand careful rewiring and load balancing |
| Residential estates & suburbs (Karen, Lang’ata, Runda, Gigiri) | New installs, earthing systems, dedicated inverter circuits, garden lighting | Larger properties need correct earthing & outdoor-safe circuits |
| High-density areas (Kawangware, Kibera, Kayole) | Safety remediation, replace makeshift joints, RCD installations, MCB upgrades | Prevent fire risk and reduce overloads where many appliances share limited circuits |
| Industrial & mixed-use (Upper Hill, Industrial Area) | Heavy load assessments, sub-distribution boards, dedicated circuits for large appliances | Mixed use properties need commercial-grade protection and segregation of circuits |
| Coastal & humid areas (Mombasa, Kilifi) | Corrosion-resistant fittings, moisture-proof enclosures, elevated cable routing | Reduce failures due to humidity and salt air |
| Towns & rural homes (Nakuru, Kisumu, Eldoret) | Solar/inverter-ready wiring, earthing improvements, consumer unit upgrades | Frequent outages and off-grid options require robust inverter-capable wiring |
Technical details & best practices we follow
We use industry best practices to deliver long-lasting, safe wiring:
- Correct cable sizing & load calculations: avoid overheating and nuisance trips.
- Zoning of circuits: separate lighting, sockets, kitchen appliances, water heaters and inverter circuits.
- Proper earthing & bonding: earth electrodes, earthing conductors, and bonding of metallic parts to reduce shock risk.
- Use of RCDs/RCBOs and MCBs: to protect persons and circuits.
- Clean terminations & labeled circuits: organized distribution board for future maintenance.
- High-quality materials: certified cables, PVC conduits (or metal where required), proper glands for outdoor runs.
- Smoke detectors & safety accessories: we can install alarm-ready wiring and recommend smoke/CO detectors.
- Documentation & testing: full test reports handed over after work.
Common signs you need rewiring
- Frequent circuit trips or blown fuses.
- Flickering lights or lights dim when appliances start.
- Discoloured or warm switch plates and sockets.
- Burning smell from outlets or switch boxes.
- Old fabric or knob-and-tube wiring in older houses.
- Outdated consumer units or missing protective devices.
If you notice any of these, call 0723613664 for a professional inspection.

Q — Do you provide materials or can I supply them?
A — We can supply all materials (recommended for warranty and quality consistency). If you supply materials we will inspect them before use and advise on compatibility.
Q — Will rewiring increase my property value?
A — Yes — safe, modern wiring, labeled DBs, and updated RCD/AFCI protection are attractive to buyers and often required at sale/inspection.
Q — What about solar and inverter systems?
A — We design inverter-ready wiring and dedicate circuits with appropriate earthing and isolation switches for seamless future solar additions.
Q — Do you issue certificates?
A — We provide a test report and certificate of completion for the work we do, which is useful for handover, sale, or tenancy documentation.
Case studies (short)
- Kilimani townhouse full rewire: Replaced an antiquated consumer unit, installed dedicated kitchen circuits and RCD protection, tidied cabling into concealed trunking. Result: no more nuisance trips and safe kitchen usage.
- Karen family home upgrade: Added inverter-ready circuits, upgraded distribution board, and installed external lighting circuits with proper IP-rated enclosures. Owner could integrate a backup inverter without rewiring.
- Embakasi apartment safety remediation: Replaced poor DIY joints and installed RCDs — immediate reduction in shocks and improved safety.
