What to check when hiring extension / renovation contractors in South Africa

MyTrustedTraders ranks on independent public evidence. No ads, no paid placement. Use these checks alongside the evidence on each profile before you decide who to contact.

  • In South Africa, electrical work must be signed off with a Certificate of Compliance (CoC) issued by a registered person. Insist on the CoC, and for plumbing look for PIRB or IOPSA registration, because without a valid CoC a future home-insurance claim can be refused.
  • For a new home or major structural build, the builder must be registered with the NHBRC (National Home Builders Registration Council) and the home enrolled before construction. Check this before you pay a deposit.
  • Ask to see a portfolio of completed work like yours, plus recent references you can contact.
  • Check the credentials and registrations that matter for this work, and that they are current.
  • Get a written, itemised quote with scope, assumptions and a staged payment schedule.

How to judge an extension / renovation contractor

Independent, no-ads guidance. The trade-specific checks that matter most, the warning signs, and what to ask before you hire. Use it alongside each tradesperson’s public evidence above.

Verify before you hire

  • Most extensions and major alterations need building plans approved by your local municipality before work starts, and a structural addition to a home should involve an NHBRC-registered builder: confirm both.
  • Check the contractor is registered with CIPC with a valid tax clearance, has an appropriate cidb grading for larger work, and carries public liability and contractors' all-risk insurance.
  • Make sure subcontracted electrical, plumbing and gas work goes to registered tradespeople who issue the required Certificates of Compliance.
  • Insist on a written contract with a detailed scope, staged payments tied to milestones, and a retention held until snagging is complete.

Warning signs of a cowboy

  • Suggests starting before the municipality approves the building plans.
  • Structural work done without an NHBRC-registered builder, or unregistered subtrades.
  • Demands large cash payments up front, or has no written contract.
  • A quote far below every other bid, or no proof of insurance.

Questions to ask before you hire

  • Are the building plans approved by the municipality, and is structural work NHBRC-registered?
  • Can I see your CIPC registration, tax clearance, cidb grading and insurance?
  • Who does the electrical, plumbing and gas work, and will they issue Certificates of Compliance?
  • Can we agree a written contract with staged payments and a retention?

Frequently asked questions

How do I choose a trustworthy extension / renovation contractor?
Compare the public evidence on each profile: how many independent reviews they have and across how many named sources, the rating and how recent it is, any credential evidence, and the company status. An extension / renovation contractor backed by several named sources is harder to fake than one found in only one place.
Does MyTrustedTraders rank or recommend extension / renovation contractors for payment?
No. There are no ads and no paid placement. Extension / renovation contractors are ranked only by the strength of independent public evidence. No one can pay to rank higher, add a badge, or change their reviews.
Where do the reviews come from?
They're imported from named public review sources and always shown with the source named. They aren't reviews written on MyTrustedTraders. We cross-check the same business across sources rather than creating new reviews.
What should I check before hiring an extension / renovation contractor?
Confirm credentials and insurance directly with the extension / renovation contractor, get a written quote, and run the Cowboy Checker on the business first. MyTrustedTraders helps you shortlist on the evidence. It doesn't replace your own checks before you hire.
