Bid Bonds

A Bid Bond is used during the tendering phase – that early stage when contractors are putting in prices to win the job.

It’s there to reassure the client (the project owner) that if a contractor is awarded the job, they’ll stick to their price and sign the contract. In other words, the Bid Bond says: “We’re serious about this tender – and we’ll back it up.”

If the contractor backs out after winning the bid, the client can claim on the bond to cover any costs of re-tendering or price differences.

When Is It Used?

A Bid Bond is submitted with your tender proposal – usually for bigger public or commercial projects where the client wants to know you’re serious about your offer.

It gives the employer confidence that if they pick your bid, you won’t walk away or change your price. It’s a simple way to show you’re committed and ready to take on the job.

The bond stays in place until the contract is awarded. If you win the job, the Bid Bond is usually replaced by a Performance Guarantee. If you don’t win, the bond simply falls away.

So, whenever you’re bidding on a project where the client wants some form of commitment, a Bid Bond is your ticket to the table.

Who Benefits?

The employer is the benificiary – They gain financial protection is the chosen contractor backs out.

the contractor benefits too as this enhances their credibility. Having an insurer-backed bid guarantee signals to the potential employer that the contractor is financially stable and is serious about the potential project.

Frequently Asked Questions

How do I apply for a Bid Bond?

You submit:

  • Your company’s financials and CIPC documents.

  • Details of the tender (employer, value, closing date).

  • Your previous construction experience.
    The insurer assesses your ability to take on the project and then issues the bond.

Do I need collateral to get an Insurance Bid Bond?

Not usually. Insurers may ask for some form of security if your financials are weak or the tender value is very high, but most bid bonds are issued against a small premium only.

Can the employer call up a Bid Bond unfairly?

They can only call the bond if you win the tender and then:

  • Refuse to sign the contract, or

  • Fail to provide the required performance guarantee.
    Insurers will investigate if the call is valid before paying.

Is the Bid Bond amount refunded to me after the tender?

No. It is not a deposit. You pay a premium (a fee) for the guarantee to be issued.

Do all tenders need Bid Bonds?

No. They are mostly required on public sector projects, large commercial contracts, and by certain employers who want extra assurance.

What happens if the contractor fails to enter into the contract?

In essence, Bid Bonds provide a guarantee that the Bidder (Contractor), if awarded the Contract will enter into the said agreement and furnish the prescribed Performance Bond. A cash deposit is required which is subject to full or partial forfeiture if the winning contractor fails to either execute the Contract or provide the required performance and/or Payment Bonds.

What documents should I have prepared for the application?
  • Company profile (including an organogram and copies of the current and previous contracts)
  • Two years’ financial statements and three months’ bank statements
  • Letter of appointment
  • Contract information
  • Guarantee wording requirements
  • Company registration documentation
  • Copies of all members’ identity documents and income tax numbers
  • Copy of letterhead
  • Tax clearance certificates
  • CIDB certificate
What will the guarantor look at when assessing my application?
  • All applications are subject to a thorough analysis to establish the Contractor’s risk profile. This will include an assessment of the Contractors’ financial standing and their resource capabilities to fulfill the Contract obligations.

    For Corporate Clients, emphasis is placed on:

    • the financial standing of the Contractor
    • the company structure and shareholding
    • the Contract information
    • the Guarantee wording requirements
    • the securities available

What Could Trigger A Claim?

Failure to sign the contract

If you are awarded the contract but then refuse or fail to sign the construction contract within the required timeframe, the employer can call on the bid bond.
Example: You win a R50 million tender, but after award you decide not to go ahead because your pricing was too low. The employer can claim against your bid bond.

Failure to provide the required Performance Guarantee

Most tenders require that after award, you must submit a Performance Bond (Performance Guarantee). If you cannot provide this within the set period, the employer may call the bid bond.


Example: Employer awards you a project and expects a 10% performance guarantee within 14 days. You fail to arrange it. The employer claims under the bid bond.

Withdrawing your bid during the validity period

If you withdraw your tender before the expiry of the bid validity period (usually 90–120 days), the employer may call the bond.


Example: You bid for a school project, but two months later you try to withdraw your tender before award because material prices have gone up. The employer can claim on the bond.

Misrepresentation in the tender submission

If the employer discovers that you submitted false information or qualifications in your tender that disqualify you after award, they may trigger the bid bond.


Example: Claiming to have CIDB grading or references you do not actually hold.

Other contractually specified breaches

Some tender conditions allow a call on the bid bond if you fail to comply with any material condition of the tender award (e.g., not attending a compulsory site handover or not mobilising when required).

Tender on Bigger Projects

Unlike Bank Bonds, we don’t require 100% collateral when issuing Bid Bonds. With cash collateral requirements of only 7–15%, our Guarantee facility allows you to free up your cashflow and tender on bigger contracts.

Ensure Your Tender's Success

When issuing Bid Bonds, the Guarantor/Insurer agrees to back you and become your co-principal debtor. This means you’ll then have a third-party’s professional opinion of your ability to perform, enter into and complete the project.

Get Your Tender Submitted Without Delay

Once your initial Guarantee facility has been approved, you can be assured of a fast and seamless process when requesting Bid Bonds for all your future tenders.

Pay Less Tax

Both the Performance Guarantee & the contingency premiums are considered insurance expenses and are therefore deductible for company tax purposes.

Save For A Rainy Day

Your Collateral Funds (Contingency Premium), reserved by the Insurer, will earn investment income at current interest rates. Should your Bid Bonds be returned, expire, or your facility cancelled, your Contingency Premium will be returned to you, inclusive of interest earned. The Contingency fund also allows you to accrue reserves for unforeseen risks on a particular project, or to allow yourself additional capacity for future tenders.
