South Africa's telecommunications contracting market is largely unregulated at the installation level. Anyone can register a company, buy a cable tester, and begin quoting on commercial projects. The result is wide variation in quality, and businesses that choose on price alone often discover months later that their cabling fails to meet the standards required for warranty coverage or network certification.
Whether you are procuring a new structured cabling installation, commissioning a fiber backbone across a campus, or contracting ongoing maintenance for an existing network, the questions below will help you separate competent professionals from under-qualified operators. Work through all 10 before you award any contract.
Licensing and Credentials (Questions 1 to 4)
Credentials are the quickest filter in the selection process. A contractor who cannot answer questions about their licensing and technician certifications is unlikely to have the depth of knowledge required for a professional installation.
Are you registered with ICASA?
The Independent Communications Authority of South Africa issues two categories of service licence under the Electronic Communications Act. A Class ECNS (Electronic Communications Network Service) licence is valid for 10 years and covers local network infrastructure. An Individual ECNS licence is valid for 20 years and authorises national-scope network service provision. Not every structured cabling contractor needs an ECNS licence. Contractors who only install internal building cabling and do not operate as network service providers fall outside that requirement. However, any company providing connectivity services, managing network infrastructure on behalf of clients, or installing infrastructure that connects to a public network must hold the appropriate licence. Ask the contractor to show you their ICASA registration number and verify it on the ICASA website before proceeding.
What cabling standards do you follow?
The answer you want is ANSI/TIA-568-E, the current edition of the Telecommunications Industry Association's commercial building cabling standard. Within that standard, ask specifically about termination convention: T568A is the preferred wiring scheme under TIA-568-E, while T568B remains common in South African commercial installations. Copper cabling categories matter too. Cat5e supports Gigabit Ethernet up to 100 metres; Cat6 reduces crosstalk and supports 10 GbE up to 55 metres; Cat6A is the recommended baseline for new installations and supports 10 GbE for the full 100-metre channel; Cat8 targets short-run data centre links at 25 to 40 Gbps. For fiber, ask whether they work with OM3 (850 nm multimode, 10 GbE to 300 m), OM4 (10 GbE to 550 m), or OM5 (wideband multimode, supports shortwave wavelength division multiplexing). A contractor who cannot explain these distinctions should not be installing your network.
What certifications do your technicians hold?
Individual technician certifications are a stronger indicator of competence than company-level claims. Look for CompTIA Network+, a vendor-neutral qualification that validates core networking knowledge and is widely recognised across South African enterprises. For network infrastructure roles, Cisco CCNA (Cisco Certified Network Associate) demonstrates practical routing, switching, and troubleshooting ability. For wireless networks, Ubiquiti UEWA (Ubiquiti Enterprise Wireless Admin) covers enterprise-grade access point deployment, which is relevant to any project involving Wi-Fi 6 or distributed antenna planning. For structured cabling specifically, Fluke Networks certifications validate hands-on cable testing and certification ability using industry-standard equipment. Ask to see copies of current certifications and check that they have not expired. Many certifications require renewal every two to three years.
Do you carry professional indemnity and public liability insurance?
Any telecommunications contractor working on commercial or industrial premises must carry both professional indemnity insurance and public liability insurance. Professional indemnity covers you if the contractor's design or advice causes financial loss. Public liability covers damage to your property or injury to third parties during the installation. Ask for a certificate of insurance, not just a verbal confirmation, and verify that the coverage is current and the insured amounts are appropriate for the scale of your project. A contractor working on a multi-floor office building with R2 million worth of network equipment should carry public liability coverage of at least R5 million per incident. If a contractor cannot produce insurance documentation within 24 hours, treat that as a disqualifying factor.
Experience and References (Questions 5 to 7)
Credentials tell you what a contractor knows. References and project history tell you what they have actually delivered. Both matter. A contractor can hold every relevant certification but have limited practical experience with commercial-scale projects in your industry.
Can you provide references from similar commercial projects?
Request a minimum of three references from projects completed within the past 24 months that are comparable to yours in scope and building type. If you are installing structured cabling in a 10-storey office building, a reference from a residential estate is not relevant. Contact references directly and ask three specific questions: Was the project completed on time? Did the final cabling pass certification testing on the first attempt? Have there been any fault calls since installation, and how quickly were they resolved? A contractor with a strong track record will encourage you to call their references. One who provides contact details reluctantly or suggests email-only contact may be concealing a less favourable outcome.
How many years have you operated in this region?
Regional experience matters more than total years in business. A contractor based in Johannesburg for 15 years may have limited familiarity with the building regulations, landlord requirements, and subcontractor networks specific to Cape Town or Durban. Ask how long they have been active in your specific metro and how many projects they have completed locally. Also ask whether they maintain a permanent local presence with warehoused stock and technicians on site, or whether they mobilise teams from another city. For ongoing maintenance contracts, a contractor without a local base introduces response time risk. A company that has operated in your city for 5 or more years with a permanent team is generally lower risk than a national operator dispatching from another province.
What testing equipment do you use?
The quality of a structured cabling installation can only be verified with calibrated, manufacturer-approved test equipment. For copper cabling, a cable certifier such as the Fluke Networks DSX-600 or DSX-8000 tests every parameter defined in TIA-568-E, including insertion loss, return loss, NEXT, PS-NEXT, ELFEXT, and PS-ELFEXT at the appropriate frequency for each cable category. For fiber, an Optical Time Domain Reflectometer (OTDR) maps the entire fiber length, identifies splice and connector losses, and detects breaks or bends. An optical power meter and light source are required to verify end-to-end insertion loss against the TIA-568-E limits. A contractor who uses a basic continuity tester and calls that a "certification" is not providing you with the documentation needed to validate a manufacturer's channel warranty. Ask to see a sample test report from a recent project.
SLA Terms and Red Flags (Questions 8 to 10)
The service level agreement is where the relationship between client and contractor is defined legally. A well-written SLA protects both parties. A vague or incomplete SLA almost always benefits the contractor at the client's expense. Read every clause before signing.
What does your SLA include?
A complete telecommunications SLA should specify response times for critical faults (4 to 8 hours is the commercial standard), mean time to repair (MTTR) for different fault categories, scheduled maintenance windows, and escalation procedures when faults are not resolved within the agreed timeframe. On the warranty side, professional contractors provide a 12-month workmanship warranty covering any defects in their installation labour or terminations. For Cat6A copper cabling installed using components from a single manufacturer's certified channel programme, a 25-year channel performance warranty is standard. This warranty is only valid when the contractor is authorised by the manufacturer and uses the correct combination of cable, connectors, patch panels, and patch cords. Ask specifically which manufacturer programme applies and confirm the contractor's authorised installer status directly with the manufacturer.
Do you provide a detailed written scope of work before starting?
Every professional telecommunications contractor should produce a written scope of work before any installation begins. This document should itemise the cable runs by location and length, specify the exact product codes for all materials, state the number of outlets, patch panel ports, and fiber terminations, and define what testing and certification documentation will be delivered on completion. The scope of work forms the basis for variations and protects you if the contractor attempts to charge for additional work that was reasonably implied by the original brief. If a contractor asks you to approve a one-paragraph quote rather than a line-item scope of work, push back before signing anything. Verbal agreements about what is or is not included in the project have no legal weight once a dispute arises.
What are the payment terms?
Standard commercial payment terms for telecommunications installations in South Africa are a deposit of 30 to 40 percent on order to cover materials, a progress payment on reaching agreed project milestones, and a final payment on sign-off of the certification report. Several red flags should cause you to pause before proceeding. A contractor requesting more than 50 percent upfront in cash with no receipt or formal invoice is operating outside normal business practice. A quote that is dramatically lower than the median from three other contractors usually indicates that the contractor has either underspecified the materials (using off-brand cable that will not meet TIA-568-E), underpaid their technicians, or does not intend to complete the project. Also verify that the contractor has a registered South African company number, a physical business address that you can visit, and a verifiable VAT registration if the contract value exceeds the VAT threshold.
"The cheapest quote rarely reflects the total cost of ownership. A cabling installation that fails certification testing costs twice: once to install and again to remediate."
Frequently Asked Questions
Do all telecoms contractors in South Africa need an ICASA licence?
No. ICASA licensing under the Electronic Communications Act applies to companies that provide electronic communications network services or electronic communications services to third parties. A contractor who only installs and maintains internal structured cabling within a building, without operating as a network service provider, is not required to hold an ECNS or ECS licence. However, if that contractor also manages connectivity, operates a private network on behalf of a client, or connects their installation to a public network, a licence becomes necessary. When in doubt, ask the contractor to clarify their licence status and the legal basis for their answer.
What is the difference between Cat6 and Cat6A cabling?
Cat6 cable supports 10 Gigabit Ethernet at distances up to 55 metres using a 250 MHz bandwidth specification. Cat6A (Augmented Category 6) extends 10 GbE support to the full 100-metre structured cabling channel by operating at 500 MHz and incorporating alien crosstalk mitigation through larger cable diameter or individual pair shielding (STP variants). For new commercial installations in South Africa, TIA-568-E recommends Cat6A as the minimum specification, as it future-proofs the installation for at least the next 10 to 15 years of network technology evolution. Cat6 is still appropriate for specific shorter-run scenarios but should not be installed as a building-wide baseline in new construction.
How long should a structured cabling installation take?
Duration depends on the number of cable runs, building type, and access constraints. As a general guide, an experienced two-person team can install and certify approximately 20 to 30 Cat6A runs per day in a straightforward open-plan office environment. A floor with 60 data points would therefore take 2 to 3 working days for installation plus half a day for certification testing and documentation. Multi-floor projects with vertical risers, raised access floors, or occupied spaces requiring after-hours work take proportionally longer. Any contractor quoting unusually short timelines should be asked to explain their methodology in detail.
What documentation should I receive after the installation is complete?
At minimum, you should receive a cable schedule identifying every run by outlet label, patch panel port, room location, and cable length; a full certification test report from the cable certifier in both PDF and the manufacturer's proprietary format (for later re-testing); as-built drawings showing the physical routing of all cable runs; warranty registration confirmation from the cabling manufacturer; and a handover document listing all materials installed with batch numbers. Keep this documentation permanently. When you commission future network upgrades or troubleshoot faults, having accurate as-built records eliminates the need to re-trace every cable manually.
