A half-built warehouse outside Brackenfell burns on a Tuesday night. By Wednesday morning three companies are on the phone: the owner, the builder, and the scaffolding firm, each certain one of the other two is paying. The policy meant to answer the question sits in a lever-arch file, unread since the day the contract was signed. Construction risk works like this: everyone assumes cover exists until the morning it has to perform.

What is contractors insurance?

Contractors insurance is the family of policies protecting a building or engineering project while it is being built: the works, the materials, the plant, and the people around them. The core policy is Contractors All Risk, with liability, plant, and specialist covers arranged around it to match the contract you've signed.

Key Takeaways

  • One policy seldom does the whole job. The works, the plant, public liability, and professional risk each need their own cover, arranged so the pieces meet without gaps.
  • The building contract decides who insures what. Under the JBCC agreements your policy must mirror the contract data, not the other way round.
  • An uninsured subcontractor's loss climbs to whoever on site carries the widest policy, so their cover is your business.
  • Cover doesn't end when the building is handed over. The defects liability period and delayed project revenue carry risks of their own.
  • A policy lapsing between projects leaves the next contract exposed from its first morning.

Contractors All Risk cover explained

Contractors All Risk, CAR in the trade's shorthand, is the policy carrying a project while it exists as neither land nor building. It covers the half-poured slab, the stacked bricks, the works in progress no buildings policy recognises yet. A completed warehouse sits on the owner's property policy, but a warehouse at 60 percent sits on nobody's. The CAR policy insures your contract works and the materials on site against fire, storm, theft, and collapse for the life of the build. The name promises more than any wording delivers. "All Risk" is the industry's most optimistic phrase, and the exclusions begin on the next page. Defective design, wear and tear, and losses after handover sit outside standard cover unless an extension brings them in. What a CAR policy excludes decides more claims than what it covers, so the exclusions deserve the first read, not the last. The reading belongs before you sign the contract, not after the loss adjuster arrives.

Contract works insurance and JBCC requirements

The building contract decides what contract works insurance you carry; the insurer only prices it. Most formal South African projects run on the agreements of the Joint Building Contracts Committee, the standard contracts the industry signs and seldom reads twice. The committee's JBCC quick guide sets out the suite, from the Principal Building Agreement down to the Minor Works Agreement. Those agreements require the works to be insured and name whether the employer or the contractor arranges the policy. They expect proof of cover before work starts on site. On alterations to an existing building, the employer commonly insures, because the existing structure and the new works share one roof and would share one fire. A policy schedule contradicting the contract data is a breach of contract before it becomes an insurance problem. When the two documents disagree, the claim lands in the space between them, and neither the insurer nor the employer is in a hurry to occupy it.

Principal-controlled and contractor-controlled policies

One project can be insured from either end: the employer buys a single policy covering every party on site, or each contractor arrives carrying its own. A principal-controlled policy puts the developer in charge of one wording naming the contractor and subcontractors. It removes the uninsured-subbie problem, but leaves each builder relying on cover they haven't read. A contractor-controlled site multiplies policies instead, and where two insurers overlap on one loss, they argue like heirs at a will reading. The table below shows where each arrangement carries its risk.

Two ways to arrange one project's cover.

Whichever end insures, you must confirm the other end isn't assuming the same thing. A risk both sides believe the other covers is a risk nobody does.

Subcontractor risk and uninsured subbies

An uninsured subcontractor doesn't shrink the site's risk; it moves the risk to whoever still has cover. A plumber's torch starts a ceiling fire; his liability policy lapsed two renewals ago. The claim climbs to the main contractor's insurer, which pays and then pursues a company with nothing to recover. The exposure is growing because the industry is fragmenting: Stats SA's construction industry figures show the largest 100 firms earned 40,0% of industry income in 2014 and 26,7% by 2024. Small and micro firms carried 55,3% of construction jobs in 2024. More of each project now passes through small firms, and small firms are where premiums get skipped in a lean month. Checking a subbie's policy before they start costs you a phone call and a certificate. Discovering the lapse afterwards costs the claim, plus the years of correspondence explaining it.

Plant, tools, and equipment on site

The CAR policy insures the thing being built; your machinery needs insuring separately. Plant All Risk covers the owned fleet, the excavators, mixers, and tower cranes, against damage and theft on site and in transit between sites. Hired-in plant is different: under most hire agreements the machine becomes your responsibility from the moment it arrives, insured or not. A hired crane toppling in an August wind is your account unless your policy says otherwise. Hand tools have their own arithmetic, since they leave a site in one of two ways: in the bakkie they arrived in, or in someone else's. Plant standing idle between contracts still burns, still floods, and still attracts attention. The cover has to follow the machine to wherever it sleeps. A plant schedule reconciled against the yard once a year keeps the sums insured honest and the claims arguable in your favour.

Public liability on construction sites

The largest liability claims on construction sites tend to come from people who never set foot on them. A brick leaves the third floor and finds a parked car. A pedestrian finds an unbarricaded trench, and a month of piling cracks the neighbour's boundary wall. None of these claimants signed your indemnity forms. The Construction Regulations under the Occupational Health and Safety Act place duties on clients, designers, and contractors to manage the risks a site creates. A breach of those duties makes the resulting liability claim harder to defend. Public liability cover pays the compensation and the legal costs when your site injures a third party or damages their property. The limit should be sized to the surroundings rather than the contract value. A R5 million limit reads one way beside an empty plot and another way beside a shopping centre.

Professional indemnity for design and build work

Contractors All Risk pays for damage you can point at; professional indemnity pays for decisions. Professional indemnity is the cover responding when a client alleges your design, specification, or advice caused their loss, and it exists because design, unlike brickwork, shows its cracks later. A design-and-build contractor carries both exposures in one signature. A raft foundation specified too thin produces cracking two years after handover. The CAR policy has long expired, and it excluded design defects anyway, so the claim now stands against the drawing rather than the damage. Without professional indemnity, the contractor defends a design claim from its own pocket, and design claims are priced in professional fees, delay, and demolition rather than bricks. If your contracts include any design responsibility, a CAR policy on its own covers half of what you signed. The other half needs its own policy, with a limit chosen for the projects you design, not the ones you merely build.

Cover during the defects liability period

Your obligations outlive practical completion, the formal handover of the finished building, and your cover has to match them. The defects liability period is the stretch after handover, commonly three to twelve months, when you must return and make good the defects the building reveals as it gets used. The building is handed over with photographs and a ribbon; the obligations stay behind. A standard CAR policy can extend into this period, covering damage you cause while remedying defects and, depending on the wording, damage from causes arising during the original construction. Without the extension, the geyser your team installed in month four fails in month fourteen and floods two floors. The claim lands on a policy no longer in force. The date to check is the policy's expiry against the contract's defects period, not against the handover party. Cover ending at practical completion protects the build; cover ending after the defects period protects the builder.

Delay in start-up cover

On a large project the most expensive loss is usually time. Delay in start-up cover, also sold as advance loss of profits, pays the principal's lost income and continuing costs when insured damage pushes out the completion date. A fire in month ten of a shopping centre build is repaired by the CAR policy. The six months of lost rental and the loan interest running through the delay are repaired by nothing. The exception is delay cover bought before the first brick. The timing rule is unforgiving: you arrange this cover at the start of the project and price it on the revenue at stake. It can't be added once the works, or the trouble, are underway. Developers financing a project on projected income feel the delay harder than the damage, because the bank's repayment schedule shows no interest in site conditions. A project with committed tenants and committed debt has more to lose from the calendar than from the fire.

Annual contractors insurance or project-specific cover

Contractors insurance comes in two shapes: an annual policy covering every contract you take on, and a project policy living and dying with one site. An annual contract works policy runs on declared turnover and covers each new job as it starts. A project-specific policy is matched to one contract's value and duration, then dies at practical completion like a wedding suit going back into its cupboard. Riot and unrest damage sits separately with SASRIA, the state-owned special-risk insurer whose cover rides on your underlying policy through a coupon. Under SASRIA's construction risk regulations a coupon issued for a specific contract runs from inception until completion. The cover goes up to R500 million on any one contract. The gap lives between projects: an annual policy keeps your plant and liability covered while you price the next tender, but a lapsed project policy covers nothing at all. The wrong shape either doubles your premiums or leaves day one uninsured.

Contractors all risk insurance: the cover that holds a project together

Contractors all risk insurance is the single policy most lenders, employers, and principal agents will ask for before a shovel breaks ground. It bundles physical loss or damage to the contract works with third-party liability into one document, so there's no gap between the two covers when collapsed formwork injures a bystander and damages the partially completed structure simultaneously. The Joint Building Contracts Committee's suite of contracts makes this expectation explicit, and most bank-financed developments require evidence of cover before the first drawdown is released.

What you stand to lose without it isn't only the reinstatement cost of damaged works; it's the entire project timeline, your retention, and your relationship with the principal. The insurance industry, to its credit, has designed a policy elegant enough to cover all of that in one document and complicated enough to void it on a clerical error. The policy wording, the declared contract value, and the list of insured parties must all match the contract documents precisely, because a mismatch is the administrative oversight voiding a claim at the worst possible moment. Our guide to contractors all risk insurance walks through what projects need covered and where the common gaps appear.

The paperwork outlasts the scaffolding

Yellow excavator, concrete mixer truck, and generator unit parked on a dusty South African construction site.

Scaffolding comes down in a day. The questions about who carried which risk arrive years later, in letters with reference numbers. By then the site huts are gone and your foreman has moved provinces. What answers those letters isn't memory; it's the wording agreed before the first delivery reached the gate. We admit to asking too many questions at the start of a project, about subbies, about hired cranes, about the neighbour's wall. It's an old habit, and it's cheaper than the alternative. The penance, as ever, is paperwork.

You shouldn't have to work out on the worst morning of a project which of three policies answers for it. With Mont Blanc Financial Services you won't.
