Performance Bonds
What They Are, How They Work, and How Contractors Can Secure Approval.
What is a Performance Bond?
With developer insolvencies increasing and development finance tightening, performance bonds are being required on an increasing number of construction projects every day. The requirement may be from a developer in order to ensure that the contractor they hire can complete the build, or that they have the safety net to replace them if they can’t. The requirement might also come from the development funder to release funds, as they want to ensure that a build can be completed no matter what happens.
Performance bonds are often described as simple financial guarantees. In reality, they are credit decisions wrapped in insurance language. From an underwriter’s perspective, the primary question is not whether the project looks attractive, but whether the contractor has the financial resilience and operational capability to survive when things do not go to plan. Here, we look at how pricing works, what insurers or sureties actually look at, and how to position applications effectively.
How performance bonds work
A performance bond is a financial guarantee issued by a surety provider confirming that a contractor will fulfil their contractual obligations. If the contractor defaults, the beneficiary can call on the bond, typically up to a fixed percentage of the contract value.
Bond values and contract requirements
Common bond sizes are around 10% of the contract value, although this varies depending on jurisdiction and contractual terms.
How much do Performance Bonds cost?
Pricing varies depending on risk profile. Typical ranges are 1%–6% (for higher-risk projects, or where applicant credit scoring is poor) of the bond value annually for standard risks.
Factors influencing Performance Bonds costs
Strong balance sheets and established contractors may achieve lower pricing, while international projects or higher-risk sectors may attract higher premiums.
Who needs Performance Bonds?
Construction contractors, infrastructure developers, engineering firms, EPC contractors and companies involved in public sector or international projects commonly require performance bonds. Often, the bond is a prerequisite for contract award or financing.
Construction contractors
General contractors guaranteeing the timely and on-budget completion of major building projects to property owners.
Infrastructure developers
Project owners safeguarding their investments by requiring completion guarantees on large-scale civil works like highways and bridges.
Engineering firms
Specialized firms guaranteeing the delivery and operational performance of complex design-build contracts.
EPC Firms
Turnkey providers responsible for managing and delivering end-to-end industrial, infrastructure, or energy facilities
Public sector contractors
Government vendors mandated by law to provide financial security before bidding on or starting publicly funded works.
International project firms
Global enterprises mitigating cross-border risk to satisfy the strict contractual requirements of foreign clients and investors.
Understanding the underwriting process
Applying for a performance bond can sometimes feel like stepping into the unknown, but the reality is that underwriters are simply looking for predictable signs of stability. To help make the process smoother and more transparent, we’ve broken down exactly how surety providers evaluate your business.
Knowing these factors upfront allows you to approach your application with confidence and put your best foot forward.
What underwriters actually look at
Financial strength is the primary factor. Underwriters focus on liquidity, leverage, profitability trends and existing workload exposure. Track record, procurement structure, contract terms and project complexity also influence underwriting decisions. Sudden growth or unclear financial reporting often increases scrutiny.
Why Performance Bond applications get declined
Declines are usually predictable.
Common issues include insufficient working-capital, excessive bond exposure, weak financial reporting, first-time contractors taking on large projects, or poorly structured contracts. In many cases, positioning and preparation could have prevented the decline.
Common underwriter objections (and how to address them
Typical objections include rapid growth without infrastructure, reliance on single contracts, unclear cashflow forecasts, and weak internal controls.
Addressing these proactively through structured submissions and realistic project planning can significantly improve approval chances.
What drives Performance Bond premiums?
Contractors often assume pricing is arbitrary. In reality, pricing reflects perceived probability of default and recovery risk; the stronger the financial position of the applicant, or the more collateral they are able to post, the lower the price of the bond.
Risk factors that increase or reduce pricing
It’s a very simple equation for the surety provider, how risky the deal is determines how much they will charge.
Factors that influence pricing include financial strength, sector risk, geographic exposure, contract structure, subcontractor reliance and historical performance. Improving financial transparency and demonstrating risk control measures can materially improve outcomes.
Performance Bonds vs bank guarantees
Performance bonds differ from bank guarantees in that surety providers expect zero-loss outcomes and assess operational risk alongside financial strength. Bank guarantees often impact borrowing capacity directly, whereas surety solutions can preserve credit lines while providing required security to beneficiaries.
A strategic approach to securing Performance Bonds
The most common mistake is treating bonds as a last-minute administrative task. Early engagement allows risk positioning, capacity planning and alignment with market appetite, leading to better pricing and faster approvals.

Frequently Asked Questions
Our dedicated Performance Bonds specialists have compiled the questions most commonly fielded regarding Performance Bonds and related topics.
Typically a performance bond can be arranged within a week. The timeframe will largely depend on the quality of information available to the underwriters, the financial stability of the applicant (the worse shape they are in, the more work will need to be done in structuring), and the type of bond required.
Yes, although it would typically be more expensive and in most cases require some collateral to de-risk the proposal.
Yes, there are a number of instances where a Corporate or Personal Guarantee may be required, or cash or adequate collateral must be posted in order to issue the bond.
If the financial stability of the applicant is poor, the risk of an insolvency is much greater and so, therefore is the possibility of the surety needing to pay out against the bond. In order to mitigate that risk – the surety will look for ways to recover expended funds.
Yes, and UK contractors can obtain bonds issued by international surety providers. The ultimate requirements will typically be determined by the beneficiary of the bond.
If, for example, the developer requires a performance bond for the main contractor on a build, that developer will need to be comfortable with the ability to call that bond in the event of a default by the contractor. If they are uncomfortable with the jurisdiction of the Surety and that creates insecurity in terms of the ability to get paid out, they will not accept the bond.
