Most builder scams share the same warning signs: no registration certificate, a large cash deposit demanded upfront, no written contract, and a refusal to issue the certificates the law requires. Separately, South Africa has a well-documented problem of criminal extortion on building sites, the so-called construction mafia, who demand a cut of the contract value. This guide covers the red flags to watch for, what to do if your site is targeted, and where to complain.
Red flags for a builder scam
Watch for these warning signs before and during a job:
- Cannot show an NHBRC or CIDB registration certificate, or delays and refuses when you ask. The NHBRC (National Home Builders Registration Council) registers new home builders and the CIDB (Construction Industry Development Board) registers construction contractors.
- Demands a large cash deposit before work starts, especially anything from 50 to 100 percent upfront.
- No written contract, or a refusal to sign one.
- No VAT registration number on the invoice when the business clearly turns over more than R2.3 million a year. R2.3 million is the compulsory VAT registration threshold from 1 April 2026, so a business above it should be registered.
- Refuses to have the work inspected, or is hostile to NHBRC inspections.
- "We don't need a CoC for this". For regulated electrical, plumbing, gas or electric fence work, a certificate of compliance (CoC) is always required, so this is always a red flag.
- Prices far below the market. A quote well under everyone else's often signals cut-rate materials, no insurance, or unlicensed workers.
The construction mafia and "site fee" demands
South Africa has a well-documented problem of criminal extortion in the construction industry, commonly called the construction mafia or "business forums":
- These groups typically demand 30 percent of the contract value as a "protection fee", or insist that specific subcontractors or labourers from their group be employed.
- They use intimidation, threats and sometimes violence to stop work if their demands are not met.
- The economic cost to South Africa is estimated at nearly R49 billion a year.
If you are approached, the safe response is firm and clear:
- Do not pay any "site fee" or "local business forum" levy. Paying funds criminal activity and marks you as a soft target.
- Document everything: video, photos, and written notes with dates and times.
- Report it to the SAPS (South African Police Service) immediately. A case number is essential, so insist on getting one.
- Report it to your municipality and to the relevant MEC (Member of the Executive Council) for Public Works.
- Contact your industry body, Master Builders South Africa, at masterbuilders.org.za.
If this happens at your own building site, you have the right to require your contractor to manage the situation. It should be covered in the contract under the force majeure or site-access clauses, so agree upfront who handles it and how.
Common mistakes
- Paying to make the problem go away. A "site fee" never ends with one payment, and it funds the people threatening you.
- Handling intimidation without a case number. Always report to the SAPS and get the case number in writing.
- Leaving site security out of the contract. Agree before work starts who is responsible if a forum turns up.
- Ignoring the small red flags. No certificate, all-cash, no contract: any one of these is reason enough to walk away.
Where to complain
- Unregistered home builder or structural defects on a new home: the NHBRC, 0800 200 824, nhbrc.org.za.
- A CPA violation or shoddy goods and services: the National Consumer Commission (NCC), 012 065 1940.
- A consumer goods and services dispute under the Consumer Protection Act (CPA): the CGSO (Consumer Goods and Services Ombud), 0860 000 272, cgso.org.za. The CGSO covers repairs, construction, painting and gardening services, so it is a useful first port of call for most trade disputes.
- A claim of R20,000 or less: the Small Claims Court, through your nearest Magistrate's Court clerk. No lawyers are required.
- A PSIRA-regulated security provider behaving badly: PSIRA (Private Security Industry Regulatory Authority), 086 133 3850, psira.co.za.
- An electrical or gas complaint: the DEL (Department of Employment and Labour), labour.gov.za.
- Extortion or threats at your site: the SAPS on 10111, and insist on a case number.
