Expert Electrical Installation & Repair Solutions
Good electrics should be almost invisible: lights that don’t flicker, plugs that never run hot, and a DB you never have to think about.
When something’s off — nuisance tripping, a burning smell at a socket, or appliances dying after a storm — it’s stressful and potentially dangerous. We handle repairs, new installs, and upgrades with a focus on safety, neat workmanship, and long-term reliability.
Doing a renovation or extension? We add new circuits, relocate points, and size wiring correctly so you’re not overloading a single plug with half the kitchen. Need better lighting? We’ll plan LED layouts that look good and use less power.
Battling load-shedding? We design and install backup solutions — inverter/charger systems with batteries, changeover switches for generators, surge protection, and clear separation of essential vs non-essential circuits so the important stuff (Wi-Fi, lights, fridge) stays on.
Everything we do follows SANS 10142-1 requirements, and where applicable we issue a Certificate of Compliance (CoC) so you’re covered for insurance, resale, and peace of mind.
Common Electrical Problems in Zimbabwean Homes & Businesses
Power tripping — overloaded circuits, faulty appliances, earth leakage faults, or damaged cables.
Hot/burnt sockets or smells — loose connections, worn outlets, or undersized wiring.
Flickering lights — poor connections, failing drivers, or voltage dips/spikes.
Aging/unsafe DB boards — no labelling, no surge/earth leakage protection, messy or overfilled wiring.
Load-shedding damage — surges and brownouts taking out electronics.
DIY/uncertified alterations — additions done without a CoC, creating hidden safety risks.
Our Approach to Electrical Work
We begin with a proper assessment, not guesswork. That means testing: insulation resistance on suspect circuits, earth continuity, RCD (earth leakage) operation, and load checks.
We trace faults methodically to find root causes — whether it’s a failing appliance, a damaged cable in a wall, or an overloaded ring feeding the whole kitchen.
When upgrading or adding circuits, we design for capacity and serviceability: correct cable sizing, protection devices that match the load, tidy routing in conduit/trunking, and a clearly labelled DB.
On DB upgrades we often add surge protection, modern earth leakage (RCD) protection, and re-balance loads to reduce nuisance trips.
For backup power, we survey your usage, size the inverter (kVA) and batteries (kWh), install a safe changeover, and move only essential circuits to backup so the system runs efficiently.
Generators get correct earthing and exhaust clearances; solar-ready clients get guidance on compliance and any municipal SSEG approval steps.
Throughout the job we keep things neat: chase and make good where we open walls, protect finishes, and keep cables clipped and aligned.
Before we leave, we test everything with you — breakers, RCDs, polarity, and backup switchover — and, where required, issue the Electrical CoC with photos and test results for your records.

Frequently Asked Questions
When do I need an Electrical Certificate of Compliance (CoC)?
A CoC is required for most new installations, alterations, and property sales/leases. If you’ve added circuits, moved the DB, installed a geyser/oven circuit, or changed significant wiring, you’ll likely need a new or updated CoC. Insurers often ask for it after a claim. We test, rectify if needed, and issue the CoC so everything is documented and compliant.
My power keeps tripping — what’s the likely cause?
Rapid tripping can be an overload (too many appliances on one circuit), a short circuit (damaged wiring/device), or an earth leakage fault (current leaking to earth). We isolate the faulty circuit, test appliances, and check the wiring so we fix the cause, not just reset breakers.
Can you install an inverter/backup system for load-shedding?
Yes. We size systems based on what you truly need to run, separate essential circuits, add changeover and surge protection, and commission the system safely. We’ll explain battery chemistry options, expected runtime, and maintenance in plain language. If you plan to add solar PV later, we design with that in mind.
How much does electrical work cost?
It depends on scope: small fixes (replacing a faulty outlet or light driver) are quick; DB upgrades, rewires, or backup power installs are larger projects. After assessment we provide a clear, itemised quote with options (repair vs replace, standard vs premium devices) so you can choose the best fit.
How long does a DB upgrade or rewire take?
A typical DB upgrade is often completed in half a day to a day, depending on complexity and labelling/testing. Partial rewires (kitchen/renovation zones) usually take 1–3 days. Full rewires vary with property size and access; we plan phases to keep you powered where possible and keep disruption minimal.
