The Contract Behind the Award: Public Sector Terms Suppliers Should Challenge in 2026

The award is not the end of the risk

In 2026, the UK public procurement regime is fully embedded. Contracting authorities have settled into their standard form contracts, framework agreements and dynamic purchasing arrangements, and suppliers have become familiar with the bid process. The risk is that attention remains fixed on winning the award rather than on the contract that follows it. Public sector terms are often presented as non-negotiable, but they are not uniformly so. Some clauses reflect legal requirements; others reflect the authority's appetite for risk. Suppliers need to distinguish between the two before signing.

The Procurement Act 2023 provides the statutory backdrop, but the commercial risks sit in the schedules. A supplier that treats contract review as a post-award administrative task may find that it has accepted flow-down obligations, audit rights, termination rights and payment mechanics that make the contract unprofitable. The following clauses deserve particular scrutiny.

Flow-down obligations

Public sector contracts frequently require the supplier to flow down obligations to subcontractors and to comply with the authority's policies. The trap is a broad flow-down of all obligations in the head contract, without limitation, regardless of whether the supplier can control or even see those obligations. A supplier may be asked to impose security requirements, data protection terms, modern slavery provisions, environmental standards and reporting duties on its supply chain, with no corresponding limitation in its own contract.

Suppliers should ask for the relevant head contract extracts and negotiate a flow-down limited to obligations that are proportionate and relevant to the subcontracted work. The clause should make clear which party is responsible for what, how changes are handled and whether the authority has direct rights against subcontractors. If the supplier cannot control a requirement, it should not accept an unqualified obligation to procure it.

Audit and access rights

Audit clauses in public contracts can be wide. Authorities may seek access to premises, records, systems and subcontractors, sometimes at short notice and at the supplier's cost. Audit rights may extend to pricing, service performance, security and compliance with the authority's policies. In isolation, an audit right may seem reasonable. In combination with open book pricing, unlimited retention periods and access to third-party confidential information, it can become a significant operational burden.

Suppliers should negotiate reasonable notice, access during business hours, a defined scope, confidentiality protections and a cost-allocation mechanism. Audit rights should not become a route to competitor intelligence or to renegotiating the contract through inspection. Where the authority requires open book pricing, the supplier should model the cost of compliance and ensure that the pricing mechanism reflects it.

Termination for convenience

Termination for convenience is common in public contracts. The authority may reserve the right to terminate without cause on short notice. The commercial question is not whether the right exists, but what happens when it is exercised. Suppliers should check whether the contract provides compensation for demonstrable commitments, unrecovered mobilisation costs, committed subcontractor liabilities and lost profit. A termination right with no compensation can be tolerable on a short, low-capital contract and unacceptable on a long-term, capital-intensive one.

Where the clause cannot be removed, suppliers should negotiate a notice period, an exit plan and payment for transition assistance. They should also price the risk into the bid. If the authority insists on immediate termination with no compensation, the supplier should consider whether the contract is worth winning at all.

Payment terms and supply chain finance

Public sector payment terms are often presented as prompt, but the detail matters. Suppliers should check when payment is triggered, whether disputed invoices can be withheld, whether payment is conditional on the authority's own funding and whether supply chain finance arrangements are mandatory. In subcontracts, pay-when-paid clauses can transfer the authority's payment risk down the chain.

Suppliers should negotiate clear payment mechanics, a defined invoice dispute process, interest on late payment and a right to suspend for non-payment. They should also check whether the authority requires retention, performance bonds or parent company guarantees, and factor those costs into the price.

Liability, indemnities and insurance

Public contracts sometimes seek uncapped liability or broad indemnities for data protection, intellectual property infringement, health and safety and breach of security obligations. The supplier should test whether the indemnity is limited to losses caused by the supplier's own acts or omissions, whether it is proportionate to the contract value and whether insurance can realistically cover it. If the authority requires a level of insurance that the market does not provide, the supplier should challenge the requirement rather than assume it can be met.

Change control and benchmarking

Authorities need flexibility, but flexibility should not become a unilateral right to change scope at a fixed price. Suppliers should ensure that changes are documented, priced and approved through a change control procedure. Benchmarking and step-in rights should be limited to defined circumstances and should not allow the authority to rewrite the commercial bargain.

When to negotiate, price or walk away

Negotiate where the clause is unclear, disproportionate or outside the supplier's control: broad flow-downs, unlimited audit scope, short termination for convenience and one-sided indemnities. Price the risk where the clause is commercially acceptable but costly: termination compensation, audit compliance, insurance and reporting. Walk away where the risk cannot be managed: uncapped liability, no compensation for termination on a capital-intensive contract, payment contingent on third-party funding or flow-down obligations that the supplier cannot perform.

A public contract is still a commercial contract. The award may be valuable, but it is not valuable at any price. Suppliers that review the contract behind the award with the same discipline as the bid are better placed to deliver profitably and to avoid disputes after mobilisation.
