Buying Better: How UK Organisations Can Build Accessibility into Supplier Contracts

Procurement is one of the most effective levers an organisation has for improving accessibility. The goods, services and digital products bought today will shape how customers, employees and visitors experience the organisation for years. Yet accessibility is often added late in the process, if it appears at all. A supplier may be asked to confirm that a product is accessible, but the contract may not define what that means, how it will be evidenced or what happens when something goes wrong.

In 2026, UK organisations have both a stronger framework and a clearer expectation to act. The Procurement Act 2023 and its associated regulations have reshaped public procurement, while organisations across the public, private and voluntary sectors are increasingly expected to consider social value and inclusive delivery. Accessibility belongs in that conversation.

This article offers practical guidance rather than legal advice. Contract wording should always be reviewed by qualified procurement and legal professionals.

Why procurement is an accessibility lever

Accessibility is not confined to a website. It affects software, documents, facilities, recruitment processes, customer contact channels, print materials and the subcontractors that deliver services on an organisation’s behalf. Each of those areas may be bought in. If accessibility is absent from the specification, the supplier has little reason to prioritise it. If it is absent from the contract, the organisation has little leverage when problems emerge.

The business case is straightforward. Accessible supply chains widen the potential customer and talent pool, reduce costly remediation and lower the risk of complaints and legal challenge. They also support reputation. Organisations that ask better questions of suppliers tend to receive better evidence and fewer unwelcome surprises.

Start before the tender

Accessibility should appear in the needs assessment, not in a final contract schedule. Define the user journeys and workplace activities the purchase must support. Identify where disabled people are likely to interact with the service, whether as customers, employees or members of the public. Then translate those needs into proportionate requirements.

For digital products, WCAG 2.2 AA is a sensible baseline for web content and mobile applications. For public sector bodies, the accessibility regulations for websites and mobile applications remain relevant. For workplace services and facilities, consider how reasonable adjustments will be requested, delivered and reviewed.

Early market engagement can help. Ask suppliers how they manage accessibility today and whether they can provide evidence. This is not about catching suppliers out. It is about understanding what is realistic and where the organisation may need to build capability over time.

What to ask suppliers

A simple yes or no question about accessibility is rarely useful. Ask for evidence instead. Depending on the purchase, useful questions include:

• Can you provide an accessibility conformance report or equivalent evidence for the proposed product?
• When was the last independent accessibility audit, and what were the findings?
• How do you test with disabled users, and how often?
• How do you handle accessibility defects, including severity and remediation timescales?
• How will you ensure that documents, training materials and support channels are accessible?
• What accessibility training do your delivery and support staff receive?
• How do you manage accessibility in subcontractor arrangements?

For services that affect employment or workplace inclusion, add questions about reasonable adjustments, accessible recruitment materials and the accessibility of premises or customer contact points. Avoid relying solely on supplier self-certification. Evidence should be current, relevant to the product being bought and specific enough to be tested.

Contract clauses that work

Good clauses are clear, proportionate and enforceable. They should define the standard, the evidence required, the process for reporting issues and the consequences of non-delivery. Vague commitments to comply with accessibility legislation are difficult to monitor and easy to dispute.

A practical clause set might require the supplier to:

• ensure that deliverables conform to WCAG 2.2 AA, or another specified standard, at acceptance and throughout the contract term;
• provide an accessibility conformance report before go-live and on an agreed periodic basis;
• maintain a remediation plan for identified issues, with critical defects addressed within a defined timescale;
• cooperate with reasonable accessibility testing and provide access to relevant evidence;
• ensure that support channels and alternative formats are available on request;
• train relevant staff on accessibility responsibilities; and
• flow down appropriate accessibility obligations to subcontractors.

Define terms such as critical, major and minor clearly. Include accessibility in acceptance criteria and change control. If a supplier introduces a new feature, the organisation should know how accessibility will be assessed before release. For higher-risk purchases, consider remedies, service credits or termination rights, but keep them proportionate to the size and nature of the contract.

Monitor without creating unnecessary burden

A contract clause is only useful if it is monitored. The most effective approach is risk-based. Critical services that large numbers of people rely on may need quarterly evidence and sample testing. Lower-risk purchases may need an annual review.

Use existing contract management meetings rather than creating a separate bureaucracy. Ask for a short accessibility update, a defect log and a remediation plan. Sample a small number of user journeys. Review complaints and feedback for accessibility themes. If issues are found, focus on whether the supplier is responding promptly and learning from them.

Internal teams also need to play their part. Procurement, legal, digital and equality leads should agree who owns accessibility requirements and who reviews evidence. Tender documents themselves should be accessible. It undermines the process if suppliers are asked to meet accessibility standards using documents they cannot read.

Current frameworks and forward-looking practice

Public sector organisations should consider how accessibility fits within the Procurement Act 2023, the National Procurement Policy Statement and relevant Crown Commercial Service frameworks. Social value considerations can include inclusive employment and accessible service delivery, provided they are relevant and proportionate. Private and voluntary organisations can adapt the same principles without the public sector framework.

In 2026, the expectation is shifting from occasional accessibility statements to evidence-based supplier management. That is a positive development. It encourages organisations to buy services that more people can use and to treat accessibility as part of quality rather than an afterthought.

Avoiding common traps

Do not leave accessibility until the contract is being signed. Do not accept a supplier’s general statement of compliance without evidence. Do not write clauses that are so broad that neither party can interpret them. And do not assume that monitoring requires a large team. A short, regular review with clear escalation routes is often enough.

The organisations that manage this well tend to start early, ask specific questions and keep the requirements proportionate. They use procurement not as a punitive exercise but as a way to build better supply relationships. The result is a more inclusive supply chain, clearer expectations and fewer barriers for the people who depend on the services being bought.
