DB board upgrades, rewiring and solar retrofit for Melrose's established 1970s and 80s homes. 5 minutes from Sandton CBD.
Melrose is one of Sandton's most established residential pockets. The character is appealing, but electrical infrastructure from the 1970s and 80s has real limitations that show up under today's power demands.
Homes built in that era were wired for a fraction of the load that a modern household draws. Back then, a house might have had a single air conditioner, no heated towel rails, no inverter, no EV charger. The wiring gauge, the DB board size and the earthing arrangements were all designed around that much lighter load. When owners add solar, a heat pump, a high-draw kitchen or a home office setup, the original wiring often cannot keep up safely. We see overloaded circuits, aluminium sub-mains, and DB boards with minimal or no earth leakage protection on a regular basis in Melrose.
A DB board upgrade replaces the original fuse-based or small MCB board with a properly rated unit carrying the right circuit breakers, earth leakage protection and surge protection. It also gives you the correct infrastructure to connect a solar inverter safely. We work to SANS 10142 throughout, and every job we complete that involves supply alterations or new circuits is covered by an electrical certificate of compliance.
Load shedding has changed the conversation around solar in Melrose considerably. Residents who have been through three or four years of Stage 4 and Stage 6 outages are no longer asking whether solar makes sense; they're asking how quickly they can get a system in and what size works for a home of their age and roof type. The good news is that most Melrose properties have generously sized roofs with good north-facing exposure, which makes them reasonable candidates for 5-8kW hybrid systems paired with a Pylontech or Hubble battery bank.
Solar on an older home does require some additional groundwork. Roof structures built 40-50 years ago are sound in most cases, but we assess the timber condition and tile or IBR panel state before we propose a mounting system. Where a roof is marginal, we recommend a structural check before proceeding rather than loading panels onto a surface that may need attention in the near future. Any grid-tied system we install is registered with City Power through the SSEG process, so your export and import metering is handled correctly from day one.
From rewiring a 1970s property to adding a solar backup system, here is what we cover in this suburb.
Replace ageing fuse boxes and undersized boards with compliant modern distribution boards. Essential before adding solar or any high-draw appliance.
Circuit-by-circuit rewiring where insulation is degraded or wiring gauge is insufficient for current loads. We can phase the work to suit your budget.
5-8kW Deye or Sunsynk hybrid inverter with Pylontech or Hubble batteries, designed for older roof structures. SSEG registration with City Power included.
Certificate of compliance for property sales, bond applications and insurance requirements. We inspect, identify defects and issue the COC once all items are resolved.
Tracing intermittent trips, unexplained outages and wiring faults in older homes where original circuit documentation may no longer exist.
Heat pump, Kwikot geyser and Heat Tech towel rail wiring on dedicated circuits, with correct MCB sizing and earth leakage protection.
Working in older suburbs requires a different approach than new builds or estates. Here is what that means in practice.
Melrose properties often have underground cable runs that were installed without the conduit protection required under current SANS 10142 regulations. When we open a trench for a new circuit or solar DC cabling, we document what we find rather than simply routing around it. Where the existing underground wiring presents a risk, we flag it and quote for remediation separately so you can make an informed decision.
Many homes in the area are rental properties or have changed hands multiple times, which means ad hoc electrical additions by various contractors over the decades. The result is often circuits that are not labelled, boards that do not reflect current wiring, and loads that have grown well beyond the original design. A thorough inspection before we do any work protects both the homeowner and ourselves as the issuing contractor on the COC.
For property transfers, the conveyancing attorney will require a valid electrical certificate of compliance before registration can proceed. In Melrose, because the housing stock is older, defect lists tend to be longer than in newer suburbs. We give you a clear written defect list with a fixed quote to remedy each item, so there are no surprises between inspection and COC issue. Explore our full COC inspection service for more detail.
If you are purchasing a Melrose home and want an independent pre-purchase electrical inspection before you commit, we offer that as a standalone service. It gives you a realistic picture of the work required and the likely cost before you take transfer. See our electrical services and solar packages for full details.
Older homes often need preparatory work before solar or COC can be finalised. We quote transparently so you know the full scope. See the full pricing guide for every package.
