With the industry’s growth fuelled by renewable energy adoption and infrastructure demands, adhering to regulations like SANS 10142 is essential to mitigate risks, ensure reliability, and avoid penalties. Non-compliance can lead to hazards, legal liabilities, and financial losses, underscoring the need for proactive adaptation amid global and local pressures. SANS 10142, the Wiring of Premises standard, forms the backbone of electrical installations in South Africa. Edition 3.2, released in August 2024, introduces updates aligning with international norms, including enhanced requirements for renewable systems like solar PV and battery storage. By March 2026, full adoption of the IEC 60364 series is anticipated, completing a phased integration that began earlier. This overhaul addresses modern challenges, such as smart technologies and embedded generation, ensuring installations are safe and efficient. Key changes include clearer guidelines for PV-to-grid synchronisation, surge protection, and energy storage systems, reflecting the surge in rooftop solar amid load-shedding concerns. Compliance extends beyond SANS to bodies like the National Regulator for Compulsory Specifications (NRCS), which combats uncertified imports flooding the market. These substandard products undermine safety and sector integrity, prompting calls for stricter enforcement. For homeowners and businesses, obtaining a Certificate of Compliance (CoC) is mandatory for property transfers, insurance validity, and regulatory adherence.

Critical risks of fire safety in residential environments ASP Fire is drawing attention to the significant fire risks in residential environments, stressing the importance of proactive fire-safety management at the household level. While fire protection in commercial and industrial sectors is highly regulated, domestic fire safety is often underestimated. “Fire risk in residential properties is frequently ASP Fire recommends a structured approach to residential fire risk, encompassing both engineering controls and behavioural practices. Measures include regular inspection and certification of electrical systems, installation of smoke detection and alarm devices, provision of portable fire extinguishers in high-risk areas, and development of clear evacuation procedures for occupants. “Fire-safety engineering is about more than compliance;
overlooked, yet the potential consequences are no less severe than in industrial facilities,” comments Michael van Niekerk, CEO of ASP Fire. “The same principles of fire prevention, detection, and suppression that are standard in industry should be applied, in a scaled manner, to the home environment.” Key contributors to domestic fire incidents include compromised electrical installations, overloaded distribution boards, faulty appliances, open-flame devices, and inadequate housekeeping. Van Niekerk cautions that such risks, while often perceived as minor, create conditions where fire can ignite and spread rapidly. “The growth rate of a typical residential fire is exponential. Within three to five minutes, conditions can become untenable. Early detection and suppression are therefore critical.” Africa, with new international investors earmarking substantial equity to support this growth. With over 750 business clients and 140 MW of installed capacity under management, SolarSaver’s approach prioritises operational cost certainty and transfers performance risk away from clients, providing a hassle-free path to affordable clean energy. “For any business owner, the fundamental question is always: ‘Am I paying as little as possible to operate my business?’” explains Lance Green, head of sales at SolarSaver. “When considering a move to solar energy, this question becomes complex, with various solar financing models presenting different risks and rewards. Many businesses are better served treating solar like a utility: pay for reliable, delivered energy, not for the headaches of asset ownership, replacements, and performance risk.” Why ‘rent’ is not a swear word Green says that while the instinct to own an asset is strong in business, it’s not always the smartest financial move for solar assets. “Businesses don’t own their connection to the national grid; they simply pay a utility for the power it supplies. SolarSaver applies this same logic to solar energy. By offering a fully serviced, funded model, we remove the significant upfront capital expenditure and the ongoing responsibilities of ownership.” “This structure aligns our incentives directly with our clients: if the system doesn’t produce power, we don’t get paid,” Green adds. “This transforms solar from a capital purchase into a predictable, low-cost operational expense.” Predictable costs in an unpredictable world One of the greatest challenges for businesses is forecasting long-term operational costs, especially with volatile electricity tariffs. The SolarSaver model provides a high level of cost certainty. “Even for complex off-grid operations, such as remote lodges, clients know exactly what their energy will cost for the duration of our term agreement, whether that is a 10- or 20-year term,” says Green. “This fixed-rate structure offers a powerful hedge against the escalating tariffs of traditional utilities, delivering significant savings and budget stability over the life of the term agreement.” When evaluating how to procure solar, decision-makers typically face three paths: an outright cash purchase, a straight asset finance lease from a bank, or a fully serviced solution like SolarSaver’s. Each has distinct implications for a business’s balance sheet and operational risk profile.
it is about risk management,” stresses Van Niekerk. “Applying proven methodologies at the residential level significantly enhances resilience and reduces the likelihood of catastrophic outcomes.” As a specialist in holistic fire-risk management solutions, ASP Fire provides consulting, system design, and compliance auditing services across commercial, industrial, and residential sectors in South Africa and beyond. The company continues to advocate for a culture of fire awareness supported by sound technical interventions.

they can access unique tax incentives or grants that require ownership and deliver significant near-term benefits. It can also be attractive for organisations with access to cheap internal capital and a strategic mandate to own critical infrastructure.” Owning a solar installation ties up capital in a long-lived but depreciating, performance-sensitive asset that will ultimately require refurbishment or replacement. Solar modules degrade and parts have finite component life. Batteries need replacement at least every 10 years, depending on duty cycles, and commercial- grade inverters offer up to 15 years’ capacity in good operating conditions. End-of-life arrives with a lumpy CAPEX requirement to replace all or part of the system, and owned systems can lag behind the rapid pace of technological advancement. Total cost of ownership isn’t just the purchase price; it includes degradation, component replacements (notably inverters and batteries), maintenance, insurance, and underperformance risk, says Green. “Even if you have the capital to fund solar assets outright, you still need to take care of maintenance and insurance, typically via a service level agreement (SLA), with an outside company. Annual SLA costs are typically 2.5% of the capital purchase price. And is your maintenance and cleaning company invested in the output of the solar asset if they don’t own the asset?” Green explains. Bank asset finance While a straight asset finance lease from a bank may eliminate the initial CAPEX, it introduces other variables. The bank’s primary interest is in the loan’s repayment, not the performance or longevity of the solar installation. This model results in full asset ownership at the end of the finance term and potential balance sheet advantages. However, Green says the cons are significant. “If financed, the business is exposed to rising rates, fees, and refinancing risk, as well as taking on the responsibility for maintenance, insurance, and repairs. Critically, if the system underperforms or fails, the loan repayments continue regardless, creating a scenario where you pay for an asset that isn’t delivering on performance.”
SolarSaver’s fully serviced solution SolarSaver’s model is fundamentally different. It is a comprehensive energy service where the client pays only for the power produced or a fixed monthly rental, with zero capital outlay, explains Green. SolarSaver designs, funds, installs, and manages the system for the duration of the agreement, usually a 20-year term. “The primary advantage is the complete transfer of risk,” says Green. “SolarSaver is responsible for all maintenance, component replacements, insurance, and continuous performance monitoring. Our revenue is tied directly to the system’s output. For a grid-tied system, clients are only billed for the green energy produced. If the system is down, they simply use the grid as before and receive no bill from us.” For a hybrid or off-grid system on a fixed rental, clients are not charged for any days the system is offline. This guarantees that the interests of the client and SolarSaver are perfectly aligned: maximum uptime and optimal performance. Peace of mind through performance-aligned billing The difference in accountability is stark. “With a bank- financed system, underperformance is the client’s problem,” says Green. “With SolarSaver, it’s our problem. This structure provides complete peace of mind that the system will remain operational and efficient.” SolarSaver teams provide full monitoring and support, ensuring operational continuity without burdening the client’s internal resources. Clients have absolutely no risk and a guarantee that their solar asset is always working for them. The bottom line is that solar is an infrastructure asset that depreciates physically and economically, requiring vigilant lifecycle management, says Green. Business leaders should not be attached to ownership, but rather evaluate a fully serviced, CAPEX-free model against a traditional purchase using their own energy usage data. “The numbers will speak for themselves, proving that the smartest hassle-free, CAPEX-free way to go solar is to treat it like the utility it should be.”

Grounded in safety: the real backbone of any electrical installation W hile smart technologies and sleek fittings often steal the spotlight in modern electrical systems, it’s the
Equally important are the accessories – lugs, glands, saddles, ties, and sleeves. These small components are often left until last, but using the wrong product can compromise the entire installation. A professional finish doesn’t end at the distribution board or the faceplate. It’s the tidy cable runs, the correctly sized lugs, and the well-earthed surge protection that reflect a job done properly. In the end, good electrical work is about more than just getting the power on. It’s about keeping it on – safely, efficiently, and reliably. And that all begins with what’s happening behind the scenes.
an afterthought. A direct or indirect lightning strike can send a surge powerful enough to fry appliances, damage infrastructure, and bring operations to a standstill. Proper surge protection devices (SPDs), installed at the right points in the system, act as gatekeepers. They absorb and redirect these harmful spikes. When paired with a solid earthing system, they provide a strong line of defence against the unpredictable. Moving on to cables – the veins and arteries of any electrical setup. High- quality cable is about more than copper and insulation. It’s about long-term performance, fire resistance, ease of installation, and the confidence that what’s behind the walls is just as solid as what’s in plain sight. consolidate real-time consumption, EPC ratings, portfolio-wide benchmarks, and performance deviations. Decision-makers will use these platforms to prioritise interventions and allocate budgets more effectively. The 7 December deadline A key message emerging from the national discourse is that the mandatory compliance deadline will not be extended. The DEE has reaffirmed that building owners, accounting officers, and organs of state will be held accountable for ensuring EPCs are obtained for all applicable buildings. Non-compliance will trigger enforcement actions and potential penalties, a significant shift that has remained enforced since the early phase of rollout. This clarity is expected to accelerate certification activity. The rise of mandatory energy efficiency plans One of the most impactful developments anticipated in the next cycle is the introduction of mandatory energy efficiency plans. After the first EPC is issued, building owners will be expected to develop structured improvement plans, use measured data to guide interventions, use smart meters to profile data, demonstrate progress during the next certification round, and incorporate EPC outcomes into broader sustainability strategies. This aligns South Africa with global best practice and will encourage long-term operational shifts rather than one-off compliance. Quality assurance: a new layer of oversight To uphold credibility and national consistency, the DEE is set to formalise a network of Quality Assurers (QAs). These independent parties will review completed EPCs, validate inspection evidence, ensure correct application of methodologies, and identify any inconsistencies. Building owners and registered EPC professionals should note that QA services
connection ensures that, in the event of a fault, current has a safe path to dissipate. This protects both people and equipment. Poor or inadequate earthing is a silent risk. It doesn’t make noise, but when something goes wrong, the consequences can be devastating. Whether you’re wiring a home or a high-rise building, correct earthing isn’t optional. It’s the base layer of every safe system. Now consider that in a country like South Africa, where summer storms are fast, frequent, and often ferocious, lightning and surge protection must never be treated as
unseen essentials that do the heavy lifting, keeping people, property, and systems safe. Among these, earthing, lightning and surge protection, and the often-underappreciated world of cables and cable accessories, form the foundation of every reliable installation, according to Voltex.

Energy Performance Certificates: what comes next? By: Claudia A. Naidoo-Hedley, sustainability specialist and SANEDI-registered EPC professional A s South Africa continues to navigate the intersecting pressures of climate change, national energy constraints, These developments reflect significant progress since the mandate’s inception in 2020. Many organisations that once viewed EPCs as compliance-heavy now regard them as strategic tools for energy cost control, asset enhancement, and long-term operational planning.
checkbox; they represent a fundamental shift in how buildings are assessed, valued, and managed. Their broader long-term impact includes: 1. National energy security: EPC-driven improvements can significantly reduce 2. Capital investment and asset value: Better-performing buildings attract higher occupancy rates, lower utilities expenditure, and increasingly, preferential lending terms tied to green performance. markets move toward decarbonisation, South Africa’s EPC system provides a measurable link between environmental goals and building operations. 4. Skills development and sector growth: The EPC ecosystem, comprising engineers, auditors, architects, graduates, trade-skilled professionals, verification professionals, and demand on an already strained grid, supporting resilience and reducing operational risk. 3. Alignment with global climate commitments: As international sustainability specialists, continues to expand, contributing to national green economy growth. matured from an introductory compliance requirement into a central component of the national energy strategy. With clear deadlines, increasing enforcement, and stronger technical oversight, the next 12 to 24 months will define how effectively the country transitions toward more efficient, resilient, and future-ready buildings. The journey ahead requires collaboration among building owners, registered EPC professionals, public institutions, and regulatory authorities. However, the benefits, which include reduced operational costs, improved building performance, stronger national energy security, and alignment with global sustainability, are more than compelling. A turning point for SA’s built environment South Africa’s EPC programme has
and evolving global sustainability standards, the built environment stands at the centre of both challenge and opportunity. Energy Performance Certificates (EPCs), mandated for specific categories of buildings, have rapidly emerged as one of the country’s most influential regulatory instruments, propelling owners, operators, and institutions towards measurable energy responsibility. With the national deadline of 7 December 2025 having remained firm, the conversation is no longer about whether EPCs matter, but rather what comes next. Understanding EPCs EPCs are not unique to South Africa. Globally, EPCs form part of established energy transition frameworks across Europe, North America, Australia, and parts of Asia. Their purpose is universal: to provide an independently verified measure of a building’s energy performance, benchmark it against predefined thresholds, and make this information publicly visible to drive behavioural and operational improvement. South Africa’s EPC framework draws from the same international principles while integrating country-specific drivers, particularly unreliable energy supply, rising operational costs, and the urgent need to modernise the country’s commercial, institutional, and public-sector building stock. National progress: tracking South Africa’s EPC journey A key indicator of progress is the number of EPCs issued nationally. The South African National Energy Development Institute (SANEDI)’s EPC dashboard indicates the national baseline and shows the number of registered EPC professionals who have maintained their issuance presence in the industry, reflecting increased competence and the upskilling of more trained professionals. The regulatory environment has become clearer, supported by stronger guidance, standardisation, and alignment with the core principles of ISO 17020, SANS 1544:2014, and SANS 10400XA:2021, ensuring registered EPC professionals maintain independence, consistency, and technical accuracy.
EPC professionals and quality assurers as industry experts The EPC landscape depends heavily on technically skilled professionals who can interpret building profiles, review consumption data, perform site inspections, validate performance, and align findings with national standards SANS 1544:2014 and SANS 10400 XA:2021. Their responsibilities extend beyond simple certification; they act as interpreters of regulations and technical expertise, providing transparency to the public. Registered professionals need to undergo continuous training to keep pace with evolving methodologies, data requirements, and policy changes. As the next phase of the EPC framework unfolds, SANEDI and the Department of Energy and Electricity (DEE) will increasingly rely on these skilled professionals to ensure credible oversight. What comes next The initial rollout of EPCs focused on compliance and capturing the national baseline performance. The next phase will shift from “What is the building’s rating?” to “What must we do about it?” Several technical developments are expected to shape this transition: 1. Larger emphasis on data analytics: EPCs generate standardised datasets that allow building portfolios to be compared, segmented, and analysed. These insights reveal patterns of energy waste, opportunities for efficiency upgrades, performance anomalies requiring deeper investigation, and trends across building types and geographic regions. 2. ASHRAE-aligned energy audits: There is a growing need for ASHRAE-level audits, particularly for buildings scoring at the lower end of the rating scale (E, F, or G). These energy audits support identification of high-impact energy- saving interventions, lifecycle planning for equipment upgrades, creating awareness of how energy is used and distributed in a building, and cost-benefit modelling of retrofits. 3. Prioritisation through digital dashboards: Energy and sustainability dashboards are set to become mainstream tools that
