Solutions for your most complex surety risks
In the UK, surety supports construction and infrastructure by providing bonds that help businesses meet contractual obligations. In a challenging economic and political climate, surety is often a better alternative to bank lines of credit because it preserves working capital, protects borrowing capacity, and provides contract-specific security.

Our products
Surety guarantees play an important role in supporting contractual obligations, regulatory requirements, and commercial confidence across a wide range of industries. They provide a financial guarantee that a party will meet its commitments, helping to protect project owners, public bodies, and other stakeholders if those obligations are not fulfilled. From construction and infrastructure to customs, tax, and professional compliance, surety bonds offer a flexible risk-management solution tailored to specific needs. The most common bond types include
Performance bond
Guarantees that a contractor will complete a project in accordance with the agreed contract terms, or the bond will compensate the beneficiary for resulting losses.
Appeal bond
Required by courts to ensure that an appellant will satisfy the judgment, costs, or damages if the appeal is unsuccessful.
Advance payment bond
Protects the beneficiary if advance payments made to a contractor are not properly used or the work is not delivered.
Customs/deferred duty bond
Secures payment of customs duties, taxes, and compliance obligations on imported goods.
Retention bond
Replaces cash retention by guaranteeing that defects or outstanding obligations will be remedied under the contract.
Pension bond
Supports the funding of pension obligations, providing reassurance that pension liabilities will be met.
Decommissioning bond
Guarantees the cost of decommissioning, dismantling, or site restoration obligations if the responsible party fails to carry them out.
Reclamation bond
Ensures land or a site is restored to a usable or agreed condition after activities such as mining, quarrying, or land disturbance.
Bid/tender bond
Guarantees that a bidder will enter into the contract and provide the required performance security if their tender is accepted.
Warranty bond
Covers defects and faulty workmanship during the warranty period after practical completion.
Letter of credit replacement
Acts as substitute security for a letter of credit, often used to replace bank-issued collateral in favour of a surety.
