What we do
Electrical Renovations Cape Town: What the Work Covers
What are electrical renovations? Any change to the wiring, circuits or board that comes with renovating a house. Doing it with the building work is cheaper and neater than coming back later.
When a kitchen, bathroom or extension is renovated, the electrics nearly always change. An electrical renovation Cape Town owners book with us usually includes some of these:
- Rewiring: replacing old cables, especially in older houses where wiring has never been upgraded.
- DB board upgrade: a new distribution board with enough circuits, earth leakage protection and space for future work.
- Plug points and lighting: more plugs where you actually need them, dedicated circuits for ovens and geysers, and lighting on separate switches and dimmers.
- Backup power wiring: a dedicated circuit and change-over for an inverter or battery, so the essentials stay on.
- Outdoor electrics: patio lights, gate motors, pool pumps and garden points, wired for weather.
We plan electrical upgrades in Cape Town homes at the drawing stage. Once the tiles and cupboards are in, moving a plug point costs far more.

Rewiring a House in Cape Town: Signs Your Electrics Need an Upgrade
How do you know if your house needs rewiring? These are the signs we look for before rewiring a house in Cape Town. Electrical renovations Cape Town homeowners delay are the ones that cost most later.
The earth leakage keeps tripping
Often a sign of damp in old wiring, a faulty appliance or a deteriorating cable. In older homes in the wet southern suburbs it often gets worse in winter.
Old board, old fuses
Ceramic fuses, a cramped board with no spare ways, or no earth leakage unit. A DB board upgrade is usually the first step.
Warm plugs, flickering lights
Loose connections or overloaded circuits can heat up. This is a fire risk and needs an electrician quickly.
Extension leads everywhere
A house that needs adaptors in every room was not wired for today’s appliances, chargers, inverters and home offices.
Rules and CoC
Electrical Certificate of Compliance Cape Town: The Rules That Apply
Do you need a certificate of compliance after electrical work? Yes. In South Africa an electrical installation must have a valid certificate of compliance, and new or altered work must be certified when it is done. Electrical renovations Cape Town inspectors and buyers accept have this in order.
Who can do it
Only a registered electrician can issue an electrical certificate of compliance. Ask for their registration before work starts.
The wiring code
Installations must meet SANS 10142-1, the national wiring code. It covers cable sizes, earth leakage protection, earthing, bathrooms and outdoor points.
Selling your home
You need a valid electrical CoC to transfer a property. For a sale it should usually be no older than two years. Renovation work done properly makes that certificate easy to get.
Insurance
After a fire, an insurer may ask whether the electrics were compliant. A certificate for the renovation work protects you.
Kandua’s guide puts a standard electrical CoC at about R950 to R1,500. On our jobs the certificate for the new work is part of the price, not an extra.
Backup and solar
Inverter and Solar-Ready Wiring in Cape Town Renovations
Do you still need backup power in Cape Town? TechCentral reported in May 2026 that the country had gone a full year without load shedding, but Eskom has warned it could return around 2029 to 2030. A renovation is the cheapest time to prepare. Electrical renovations Cape Town families book now should include it.
Essential circuit
We split the board so lights, plugs for the router, TV and fridge, and the gate motor sit on an essential circuit that an inverter can carry.
Space and cable routes
We leave space and a cable route for an inverter and battery in a ventilated spot, and conduit to the roof for future solar panels.
City authorisation
The City of Cape Town says all solar PV systems in its supply area must be authorised before they are switched on, and it applies to battery systems too. Since October 2023 it no longer accepts new off-grid or standby applications, so new systems are treated as grid-tied and need a City-approved inverter.
Lower bills
Cape Town electricity tariffs rose 6.7% to 7.5% on 1 July 2026. LED lighting, a geyser timer and better switching cut the bill whether or not you add solar.
Portable plug-in UPS trolleys do not need City authorisation, but anything wired into the house does. We wire the house so the installer can connect and register the system correctly.

Electrical Renovation Cost Cape Town: Guide Prices
How much does it cost to rewire a house in Cape Town? Kandua’s current guide puts whole-house rewiring at about R10,000 for a very small property up to R80,000+ for a larger home with complex wiring, including labour, materials and certification. Electrical renovation Cape Town prices depend on the house more than the board.
These figures come from Kandua and are guides, not quotes. Prices go up where walls must be chased through old plaster, ceilings are low or there is no roof access. Every electrical renovation Cape Town quote we send lists each point and circuit.
Across Cape Town
Electrical Upgrades Cape Town: What We See by Area
Electrical upgrades Cape Town homes need depend on the age of the house and the weather. Electrical upgrades Cape Town wide follow the age of the house.
Older suburbs
Observatory, Woodstock, Rondebosch and Wynberg have many houses with old wiring that has been added to over decades. Full rewiring is common.
Northern suburbs
In Kuils River, Bellville, Brackenfell and Durbanville, 1970s to 1990s homes often need a new DB board, more circuits and inverter wiring rather than a full rewire.
Coastal areas
In Sea Point, Fish Hoek, Muizenberg and the Strand, salt air corrodes outdoor fittings and connections. We use weatherproof, marine-grade fittings outside.
Wet winters
In Newlands, Constantia and Bishopscourt, heavy rain means outdoor points, gate motors and pool pumps need proper protection and earth leakage.
How we work
How Electrical Renovations in Cape Town Run, Step by Step
How long does rewiring take? A small house can be rewired in a few days. Electrical work inside a bigger renovation runs alongside the building programme. Every electrical renovation Cape Town job we run follows these steps.

Do I need a certificate of compliance after electrical renovations?
Yes. New or altered electrical work must be certified by a registered electrician, and you need a valid electrical CoC to sell the property.
How often does an electrical CoC need renewing?
A CoC does not need renewing while nothing changes, but for a property sale it should usually be no older than two years, and any new work needs certifying.
How do I know if my house needs rewiring?
Frequent earth leakage trips, an old fuse board, warm plugs, flickering lights, burning smells or extension leads in every room are all signs. An electrician should test the installation.
Do I need to register my solar or battery system with the City of Cape Town?
The City says all solar PV systems in its supply area must be authorised before switching on, including battery systems. Portable plug-in UPS trolleys are exempt.
Is load shedding over in Cape Town?
TechCentral reported in May 2026 that there had been a full year without load shedding, but Eskom has said it could return around 2029 to 2030. Wiring for backup during a renovation is still sensible.
How long does a DB board upgrade take?
Usually a day for the board itself, with the power off for part of it. Adding new circuits takes longer.
Can electrical work be done while I live in the house?
Yes, for most jobs. The electrician switches off one circuit at a time and keeps the rest of the house powered where possible.
