Electrical Design & DB Inspections

A residential Certificate of Compliance (COC) in Cape Town typically costs between R800 and R2,500 depending on the size of the property and whether any remedial work is required to bring the installation up to SANS 10142 standard. A COC is valid for two years from the date of issue, after which any change of ownership requires a new COC. Some insurance policies and bond requirements also specify a maximum age for the COC. The cost quoted by ASH Electronics includes the inspection, the certification if the installation is compliant, and a detailed report. If remedial work is needed, we provide a separate itemised quote before proceeding.

A standard residential DB board upgrade — replacing an old fuse board or non-SANS-compliant panel with a modern MCB and RCCB-equipped board — typically costs between R3,500 and R8,000 in Cape Town, depending on the number of circuits, the board location, and whether rewiring of individual circuits is required. Commercial and industrial DB upgrades are quoted on a case-by-case basis. In many cases, upgrading the DB is required to issue a valid COC, particularly for older properties in Lansdowne, Wynberg, and other established Southern Suburbs neighbourhoods where the original wiring may date back 30 to 40 years.

South African law requires a valid COC whenever a property changes ownership — the seller must provide a COC to the buyer as part of the transfer documentation. A new COC is also required whenever electrical work is completed, including new circuits, DB upgrades, solar installations, EV charger installations, and inverter integrations. Landlords are required to have a valid COC for rental properties, and many municipal bodies including the City of Cape Town may require it for new development approvals. Failure to have a compliant installation can void your homeowner's insurance in the event of an electrical fire.

Our electrical inspection covers the complete fixed electrical installation of the property. This includes the DB board — condition, labelling, MCB ratings, RCCB presence and function, earthing and bonding; wiring condition as far as visually accessible; socket outlet and light switch condition; earthing of metal structures; presence and condition of surge protection devices; compliance of any recent additions such as solar systems, inverters, or EV chargers; and testing of earth continuity, polarity, and insulation resistance where required. The report identifies all non-compliances with SANS 10142 and rates them by severity so you can prioritise remediation.

A dedicated data point is a structured cabling outlet — RJ45 Ethernet — wired back to a central patch panel or switch, providing a reliable wired internet connection independent of WiFi. Planning dedicated data points on a floor plan before building or renovating means the cabling is run invisibly inside walls and ceilings rather than as surface-mounted trunking added after the fact. ASH Electronics plans electrical circuits and data points on the same floor plan simultaneously, ensuring that every data point has an adjacent power outlet, that cable routes do not run parallel to power cables (to avoid electrical interference), and that the structured cabling plant meets TIA-568 standards. This integrated approach prevents the most common mistakes that occur when electricians and IT contractors work independently.

Surge protection operates at two levels: Type 1 or Type 2 surge protective devices (SPDs) installed at the main distribution board protect the entire building installation from high-energy surges caused by lightning strikes on the municipal grid or nearby structures. Type 3 point-of-use surge protectors at individual outlets protect sensitive electronics — computers, televisions, NAS devices, and VOIP phones — from residual surges that pass through the Type 1/2 protection. Cape Town and the surrounding Southern Suburbs experience significant lightning activity, and load shedding-related grid switching also introduces voltage transients. ASH Electronics specifies and installs surge protection appropriate to the value of equipment being protected, always treating it as a mandatory component rather than an optional add-on.

Yes, this is one of our specialised services. We produce integrated electrical and structured cabling plans on your architect's or contractor's floor plan, coordinating the placement of DB board feeds, circuit breakers, socket outlets, light fittings, dedicated data points, CCTV camera positions, access control wiring, PABX cabling, and alarm system zones before a single cable is pulled. This planning service prevents costly post-completion remediation and ensures that the finished property meets current SANS 10142 electrical standards and TIA-568 structured cabling standards. We serve new builds and renovations across Cape Town, including Lansdowne, Claremont, Rondebosch, Kenilworth, Tokai, and all surrounding areas.
