What electrical work and a COC cost, and what's included
Understand what electrical work and COC certificates actually cost. Learn what drives prices and what cheap quotes leave out.
A low electrical quote isn't a red flag by itself—but a quote that won't specify materials, won't put the scope in writing, or is unclear about whether a COC is included can mean something vital is missing. Understanding what actually goes into the cost of electrical work and a Certificate of Compliance (COC) helps you spot a genuine offer from one that will cost you far more later.

What drives the price of electrical work
Electrical labour charges depend on job complexity, access difficulty, and how much diagnostic work is needed. Simple work—replacing a switch or extending a circuit in an accessible space—costs less than rewiring a roof void or troubleshooting faults in walls. If the electrician has to chase walls, lift floorboards, or work at height, time and risk both rise. The condition of existing wiring matters too. Work on an older home with degraded cables or outdated fittings takes longer than work on a well-maintained property.
Materials are the second leg. Cable, switches, outlets, circuit breakers and safety equipment all have real costs. An electrician's quote should specify which materials they plan to use, so you know whether you're getting standard-grade, compliant components regardless of the price point. Ask what brands and specifications they plan to use—not to demand premium names, but to ensure they're supplying standard-grade, compliant products. A quote that lists materials separately from labour lets you see what you're actually paying for.
Some jobs also require inspections or testing before work starts. If the electrician needs to identify faults, map existing circuits, or check earthing and continuity, that investigation time is part of the cost. It's not padding; it's how they know what they're fixing and whether the job is safe to proceed with.
What a COC adds and why it's not optional
A Certificate of Compliance certifies that the electrical installation meets the National Building Regulations and SANS standards. It's not a sticker the electrician adds for free at the end. Issuing a valid COC requires the electrician to carry out thorough testing, documentation, and professional sign-off. That takes time and carries liability for the person who puts their name to it.
The cost of a COC is embedded in the electrician's quote—it covers the testing equipment, the inspection time, the compliance paperwork, and their professional indemnity insurance. If a quote claims it includes a COC but doesn't specify what testing will be done or what documentation you'll receive, ask for those details before agreeing. A legitimate COC must show test results, circuit details, and the electrician's registration number. If the electrician is reluctant to explain this or suggests a "quick" COC without proper inspection, that's a red flag.
Some electricians quote for the work and the COC separately. This is fine and can even be clearer—you can see both components. Others roll it into one price. Either way, don't accept a quote that's vague about whether the COC is included or treats it as an afterthought.
Comparing quotes: what to look for and what to ignore
Two quotes for the same job may differ because one electrician is using better-quality materials, another has lower overheads, or one has priced in more thorough testing. A quote should list the scope of work, materials to be used, labour time, and explicitly state whether a COC is included and what testing it covers.
Beware of quotes that give no detail, regardless of price. "Rewire house—R5000" tells you nothing. You don't know if that includes a COC, what materials are included, whether fault-finding is priced in, or what happens if complications emerge during the job. A vague quote is an invitation to disputes later.
Asking three to five electricians for detailed quotes (not just a phone estimate) takes more time but protects you. When you compare, you're not chasing the lowest number—you're looking for which electrician has explained the work clearly and priced each component fairly. On Strove, verified electricians can walk you through what your specific job involves and why their pricing reflects the actual scope.
Common questions
- Does the COC cost extra on top of labour and materials?
- A COC is not a separate charge bolted on at the end—the cost of testing, inspection, and compliance documentation is built into the electrician's quote. Some electricians price it separately so you can see the breakdown; others include it in the labour rate. Either way, a legitimate COC is not free and reflects the time and liability involved in signing it off.
- Why do quotes for the same job vary so much?
- Differences in material quality, labour rates, overhead costs, and how thoroughly the electrician plans to inspect and test the work all affect price. A quote that doesn't itemise what's included may leave out detailed fault-finding or specify which materials will be used—ask each electrician to spell out what's included so you're comparing like-for-like, not just numbers. Ask each electrician to spell out what's included so you're comparing like-for-like, not just numbers.
- What should I watch for in a suspiciously cheap quote?
- Be cautious if the quote is vague about materials, testing, or whether a COC is included. If the electrician won't explain what they're supplying or how they'll issue the COC, that lack of clarity itself is the concern, whatever the price—ask them to put the scope, materials, and COC process in writing. A proper quote explains the work, lists materials, and clarifies the scope of testing.
- Can I get a COC without paying for a full inspection and test?
- No. A valid COC requires the electrician to carry out prescribed testing to confirm the installation meets regulations. If someone offers a COC without proper inspection and test results, it's not legitimate and won't be accepted for home sales or insurance purposes.
